A Detailed Explanation of BenPay's Self-Custody and Fund Security Mechanism
The security of an on-chain yield card fundamentally hinges on three elements: whether assets are under user self-custody, whether fund flows are fully verifiable on-chain, and whether the yield strategy originates from secure and transparent curated protocols. The BenPay On-Chain Yield Card achieves the unification of secure yield generation and instant spending through its "self-custody" architecture and the automated execution of on-chain smart contracts, while ensuring users' absolute asset control. This article aims to objectively analyze the security design of the BenPay On-Chain Yield Card, covering its self-custody principles, smart contract guarantees, and the risk control logic behind its curated yield strategies.
I. The Core Security Foundation: The Essential Difference Between Self-Custody and Traditional Custody
The security cornerstone of the on-chain yield card is self-custody. This means private keys are entirely user-controlled, and assets always reside in the user's personal blockchain address; the platform cannot access them. This is fundamentally different from entrusting assets to a centralized platform, as detailed in the comparison below:

II. In-Depth Security Mechanisms: How the On-Chain Yield Card Safeguards Funds and Yield
II.1 Technical Foundation: Smart Contracts Ensure Process Security
Fund security is automatically guaranteed by audited, public on-chain smart contracts, with a transparent and verifiable process:
Deposit & Lock: When a user deposits stablecoins, the funds are locked in a public smart contract.Strategy Execution: After enabling interest generation, the contract automatically deploys card accounts' idle balances to rigorously vetted mainstream DeFi yield protocols.Yield Compounding: Generated interest is automatically credited to the contract balance, enabling reinvestment.Instant Spending: During a purchase, the contract automatically settles the required amount and completes the payment. Funds always circulate within an on-chain loop secured by the user's private key.
II.2 Yield Security: Curated Strategies and Risk Control
The security of "yield generation" is a core aspect of this product. Its safety stems not from high-risk speculation but from prudent strategy design:
Protocol Vetting Criteria: Only integrates blue-chip DeFi protocols (such as Aave, Compound) that have undergone long-term market validation and are based on over-collateralization, avoiding nascent or structurally complex risky protocols.Risk Diversification: Funds are distributed across multiple robust protocols via smart contracts, preventing total loss from a single point of failure.Real-Time Monitoring & Transparency: The asset allocation and performance of all strategies are publicly visible on-chain, allowing for real-time monitoring by any third party.
II.3 Operational Security: Ultimate Responsibility and Tools for Private Key Management
In the self-custody model, user management of private keys is the final security barrier. The on-chain yield card guides best practices through its design:
Hardware Wallet Compatibility: Supports connection to mainstream hardware wallets, enabling offline private key storage and providing the highest level of security isolation for assets.Non-Custodial Design: The platform does not store and cannot recover user private keys or seed phrases, eliminating the risk of centralized database breaches at its root.Security Guidance: Provides clear security education at critical operation points, reminding users to perform offline backups and assume self-custody responsibility.
III. Direct Answers to Common Security Questions (Q&A)
Q1: If the issuing party ceases operations, will my assets be affected?
A: No. Because the assets always remain in the blockchain smart contract, controlled by your private key. Even if related services are discontinued, you can still interact directly with the contract via a blockchain explorer to withdraw your assets independently.
Q2: Where are the funds for yield generation placed? How is the security of these DeFi protocols ensured?
A: Funds are automatically deployed by the smart contract to the aforementioned curated blue-chip DeFi protocols. These protocols have undergone long-term real-world testing, multiple code audits, and employ over-collateralization models, with their security widely recognized within the industry. The platform continuously monitors the health of these protocols.
Q3: During payment, how are my transaction privacy and overall fund security maintained?
A: Payment involves only the settlement of a portion within the smart contract. Your total asset balance and other transaction history remain securely protected by your private key. All transactions are visible on-chain but are linked only to anonymized address information, offering a different privacy characteristic compared to traditional banks.
Conclusion
The BenPay On-Chain Yield Card constructs a tripartite solution that unifies security, yield, and liquidity by integrating self-custody asset control, the transparent automation of on-chain smart contracts and blue-chip protocols. Its security model can be summarized as: user-controlled private keys + publicly executed contracts + prudently selected strategies, offering a dependable tool for users who prioritize asset sovereignty and capital efficiency.

Les cartes de rendement en crypto sont-elles sûres ? D'où provient le rendement ? La dépense affecte-t-elle les gains ? Y a-t-il des frais cachés ?
Avec l'émergence des cartes de rendement en crypto, de plus en plus d'utilisateurs commencent à explorer des moyens de générer un rendement sur la chaîne à partir de leurs actifs numériques tout en les utilisant pour leurs dépenses quotidiennes. Toutefois, pour les utilisateurs occasionnels, les questions les plus importantes ne sont pas de savoir s'ils « peuvent gagner », mais si le mécanisme de rendement est transparent, si les risques sont maîtrisables et si les coûts sont clairement indiqués.
Cet article détaille les principaux points à considérer avant d'utiliser une carte de rendement en crypto pour la première fois — en abordant les sources de rendement, les frais, les risques, la sécurité et le flux opérationnel — afin de vous aider à éviter jusqu'à 90 % des pièges courants.

Avec de plus en plus de commerçants et de réseaux de paiement qui acceptent les actifs cryptographiques, les cartes de paiement cryptographiques évoluent progressivement de la question "peuvent-elles être utilisées" à celle de "comment les utiliser de manière plus efficace". Dans ce processus, les cartes de cashback cryptographiques et les cartes de rendement cryptographiques (également appelées cartes de rendement sur chaîne) sont devenues les deux produits les plus comparés par les utilisateurs.
Elles semblent toutes pouvoir "générer des profits tout en étant utilisées", mais les différences essentielles sont très évidentes en ce qui concerne les sources de revenus, la structure des risques, le contrôle des actifs et le public cible. Cet article se concentrera sur la comparaison de ces points clés et utilisera la carte BenPay comme exemple concret d'analyse.

While Decentralized Finance (DeFi) has made earning passive income on stablecoins accessible to everyone, a significant hurdle remains: the constant trade-off between liquidity and utility. Traditionally, if you wanted to earn yield, your funds may be locked away; the moment you needed to spend, your earnings stopped. Most traditional crypto payment card options function as "pass-through" tools that hold your funds in non-interest-bearing accounts, essentially letting your money sit idle and lose value overtime while you wait to swipe.
Imagine a world where your money never stops working for you—where you earn high-interest returns until the very second you pay. This is the era of the On-Chain Yield Card, a new category of crypto payment tool that allows you to "Earn While You Spend." By bridging the gap between on-chain yield investment and daily liquidity, this on-chain solution is fundamentally redefining how Web3 users manage their wealth in the real world.
What is an On-Chain Yield Card?
An On-chain Yield Card is a next-generation crypto payment tool. Beyond the standard spending features of traditional crypto cards, it allows the card balance to participate in on-chain yield strategies. Unlike traditional cards, which act solely as payment gateways where funds remain idle, an on-chain yield card—once the 'earn' feature is activated—allocates funds to DeFi protocols to generate potential returns.
In short: While funds in a traditional crypto card simply sit waiting to be spent, the balance in an On-chain Yield Card captures potential yield while maintaining full liquidity.
How Does an On-Chain Yield Card Work? Where Does the Revenue Come From?
The core of an On-Chain Yield Card lies in its ability to allow card account balances to participate in on-chain yield strategies rather than simply sitting idle awaiting consumption. Unlike a Traditional Crypto Payment Card, once a user actively enables the "Earn" feature, the account balance participates in on-chain DeFi protocols according to preset strategies to seek potential returns. This process is transparent, verifiable, and executed by smart contracts, ensuring users maintain full control over their funds. Please note that yields fluctuate with market volatility, and fixed returns are not guaranteed.
The income generated by these cards typically originates from the following sustainable on-chain sources:
Over-collateralized Lending: The most common source of yield. Assets are provided to decentralized lending protocols such as Aave or Compound. Since borrowers must provide collateral higher than the loan amount, the risk of principal loss is minimized while interest flows back to the depositor.Staking and Network Rewards: For compatible Proof-of-Stake (PoS) assets, yields are earned by participating in the security validation of the blockchain network itself.Liquidity Provisioning: Funds are used to provide liquidity for decentralized exchange (DEX) pools. In return, holders receive a proportional share of transaction fees generated by global trading activity.Tokenized Real-World Assets (RWA): Advanced on-chain solutions are bringing institutional-grade yields—such as tokenized U.S. Treasuries—directly into account balances. This allows users to capture government-backed "risk-free" rates while maintaining 24/7 liquidity.
The entire lifecycle is automated. When a transaction occurs at a Point of Sale (POS), the system triggers "instant" liquidation, redeeming only the precise amount required to settle the payment. The remaining balance continues to generate yield uninterrupted, ensuring your funds are continuously compounding until the very moment of consumption.
On-Chain Yield Card vs. Crypto Payment Card: What’s the Difference?
To understand the difference between a yield card and a Traditional Crypto Payment Card, one must first examine how standard crypto cards work. While they successfully bridge crypto assets with real-world payments, their design prioritizes spending convenience over asset efficiency, leaving idle balances unable to generate yield.
How a Traditional Crypto Payment Card Works?
A Traditional Crypto Payment Card is essentially a "bridge" or "gateway" tool. The process is typically linear: you manually "top up" a custodial wallet where funds sit as "dead assets" until they are converted into fiat at the time of payment. This model forces users to sacrifice yield potential for the sake of spending convenience.
Flaws of Traditional Crypto Payment Cards:
The "Idle Asset" Trap: Most traditional cards require you to deposit funds into a zero-interest wallet. If you keep $5,000 in your card for monthly expenses, those assets are effectively "dead."Yield Interruption: To spend, funds must be moved out of yield-bearing accounts, causing interest generation to stop immediately.Centralization Risk: Most standard cards are custodial. You do not own private keys, and the security of your funds depends entirely on the platform.Invisible Fees: Many traditional cards hide poor exchange rates or high "spreads" when converting cryptocurrency to fiat.
Why the On-Chain Yield Card is Outperforming Traditional Crypto Payment Cards

As the global economy transitions toward a 24/7 digital model, the on-chain yield card represents the future of Web3 payments. It eliminates the outdated practice of ‘parking’ funds in non-interest-bearing accounts. In this new era, holding funds is just as profitable as asset appreciation—giving your daily balance a higher velocity of capital and more generous returns than traditional savings accounts.

Frequently Asked Questions (FAQ)
Q1: Are on-chain yield cards safe compared to traditional bank cards?
While traditional bank cards are protected by government schemes, on-chain yield cards rely on the security of blockchain technology and audited smart contracts. By using an on-chain yield card, you enjoy asset transparency—you can clearly see where your funds are—and if it is a self-custodial card, you are the only one with the authority to move your assets. However, please note that risks still exist; please assess your personal risk tolerance before use.
Q2: How is an on-chain yield card different from a High-Yield Savings Account (HYSA)?
While both offer interest in balances, an on-chain yield card typically provides relatively secure and stable returns by directly accessing curated decentralized protocols. Additionally, yields fluctuate with market conditions, and a fixed return is not guaranteed.
Q3: How is the APY of an on-chain yield card calculated?
The APY of an on-chain yield card is determined by the market supply and demand of the underlying DeFi protocols and will fluctuate with market changes. Actual returns may increase or decrease, and a fixed return is not guaranteed.

With the growing adoption of cryptocurrency payments, more and more people want to use their crypto assets for everyday spending instead of letting them sit idle in a wallet. This raises a common question:
Is there a crypto debit card that can be used for daily transactions while the balance also earns yield?
The answer is yes. This is exactly what the BenPay On-Chain Yield Card offers — letting your funds grow while remaining readily available.
What Is an “Earn-While-You-Spend” Crypto Debit Card?
An “earn-while-you-spend” crypto debit card is essentially a card that combines payment functionality with an optional yield-generating mechanism.
It works like a regular debit card for spending, but also allows the unused balance in your card account to earn interest once the user activates the “Earn” function. This type of product is called an On-Chain Yield Card
Core features:
Have crypto assets in the card account earn yield after the user chooses to enable itSpend funds anytime without restrictionGrow their balance dynamically without extra manual operations
Unlike cashback crypto cards or simple staking tools, it offers a more flexible and transparent revenue experience.
BenPay On-Chain Yield Card: Grow Your Funds While Keeping Them Accessible
The BenPay On-Chain Yield Card is designed specifically for crypto users, with its core value in:
On-Chain Yield (User Activated)
When a user clicks the “Earn” button on their card account balance, the eligible balance participates in on-chain yield protocols, achieving:
Interest generationReal-time yield updatesDaily settlementTransparent on-chain tracking
Compared to traditional bank deposits, this provides higher returns and full transparency.
Note: Yield applies only to the card account balance chosen by the user, not the entire card balance. Funds are not automatically deducted — yield starts only after the user activates the feature.
Ready-to-Use Funds, No Lock-Up
Even when assets are earning yield on-chain, they remain accessible:
Payments are deducted directly from the card balanceNo need to redeem or pause yield in advanceNormal spending is unaffected
This means users can earn yield while keeping their funds ready for spending.
How Does an “Earn-While-You-Spend” Cryptocard Work?
The mechanism consists of three main components:
On-Chain Yield Protocol
After the user enables yield, the card account balance participates in long-tested, blue-chip DeFi yield protocols, such as AAVE, Compound, Morpho, Sky and more, achieving stable asset growth (APY starting from 3%, subject to market conditions and is not guaranteed).
Yield sources, contract addresses, and operational logic are executed on-chain and can be independently verified by the user.

Real-Time Payment System
When a user makes a purchase, payments are deducted from the available card balance.
Balances that have enabled yield continue to generate returns according to the protocol, without being interrupted by spending.
The payment process requires no extra steps, allowing transactions and yield accumulation to run in parallel.
Security and Transparency
All operations are executed on-chain, ensuring transparency and security:
Card account balances and yield status are always viewableYield sources and settlement logic are publicly verifiableUsers retain full control over whether to enable yield
How Is It Different from Traditional Crypto Cashback Cards or Staking?

Traditional crypto cards typically provide a small percentage of cashback, while staking requires locking assets with risks and unlock periods. The On-Chain Yield Card allows funds to earn yield while remaining accessible, but requires the user to activate the yield feature.

Who Is This Card For?
The BenPay On-Chain Yield Card is ideal for:
Users who want to make idle crypto assets work for themThose with frequent fiat or crypto payment needsUsers who value transparency and the ability to withdraw anytimePeople who don’t want to lock funds in staking protocols
Especially suitable for:
Users who want to spend crypto anytimeUsers who prefer automatic yield management without manual stakingUsers who want to maximize returns while maintaining flexibility
BenPay On-Chain Yield Card FAQs
Is earning on the BenPay On-Chain Yield Card automatic?
No. Earning is generated only after the user manually activates the “Earn” feature. Before activation, the card account balance does not participate in any on-chain yield protocols, and funds are never automatically deployed.
Are funds locked after enabling on-chain yield?
No. Enabling on-chain yield does not lock funds or restrict spending. Users can continue making payments at any time without redeeming or pausing yield, with no lock-up or unbonding period.
What is the difference between an on-chain yield card and staking?
Staking requires locking assets, while an on-chain yield card keeps funds fully liquid. Yield on the card is optional, user-activated, and does not limit payment usage, unlike traditional staking mechanisms.
Is on-chain yield risk-free?
No. On-chain yield involves risks associated with DeFi protocols. These include smart contract risk, protocol-level market risk, and asset price volatility. Transparency does not eliminate risk, and users should decide independently whether to enable yield.
Who is an earn-while-you-spend crypto debit card suitable for?
It is best suited for users who want to earn yield on idle crypto while retaining full spending flexibility. Users who prefer fixed returns or fully regulated traditional financial products may find this model unsuitable.
Conclusion
An on-chain yield card is not designed to replace banks or staking — it redefines how funds behave while being used. Traditionally, money is either spent or invested. The BenPay On-Chain Yield Card introduces a different approach: allowing funds to remain spendable while optionally earning yield — without lock-ups. Only when the user explicitly enables yield do funds continue to generate on-chain earnings while being used for payments, according to transparent on-chain protocol rules.
For users who value:
Liquidity without sacrificing on-chain yields potentialTransparent, on-chain–verifiable mechanismsFull control over whether yield is enabled
The BenPay Crypto Debit Card offers a new “earn-while-you-spend” experience that differs fundamentally from crypto cashback cards or staking products.

Introduction
Alors que l'écosystème DeFi continue de mûrir, les opportunités de générer un rendement sur la chaîne ne sont plus rares. Ce qui retient vraiment les utilisateurs, ce n'est pas le manque d'opportunités, mais les barrières à la participation. Des mécanismes de protocole opaques, des règles hautement spécialisées, des flux de fonds peu clairs et des étapes opérationnelles complexes découragent souvent les utilisateurs. Même lorsque les utilisateurs reconnaissent que leurs actifs pourraient être utilisés de manière plus efficace, beaucoup choisissent encore d'attendre ou de laisser leurs fonds inactifs pendant de longues périodes.

À mesure que les cryptomonnaies évoluent, passant d'une cible d'investissement à un outil de paiement, une question plus fondamentale surgit : la « carte crypto » que nous tenons entre les mains est-elle simplement un canal de dépenses, ou s'agit-il d'un moteur d'actifs auto-entretenus ?
Imaginez ce scénario : vous avez 5 000 USDT sur votre carte, en attente de votre prochain voyage d'affaires, de votre réservation d'hôtel ou de vos dépenses quotidiennes. Pendant ces 60 jours où vous ne les avez pas dépensés, ils n'ont rien fait. Le problème ne réside pas dans le fait de les dépenser ou non, mais plutôt : ces 5 000 USDT auraient pu continuer à générer des revenus pendant qu'ils « attendaient d'être dépensés ».

【January 8, 2025】According to an official announcement, BenPay DeFi Earn has officially launched four new investment targets: Morpho USDC, Morpho USDT, Sky USD, and Ethena USDe, further enriching users’ secure and stable asset growth options in the DeFi space.
All new investment targets are selected from DeFi protocols with on-chain verifiable mechanisms, covering a range of yield-generation models. The relevant yield data is public and transparent; however, actual performance may vary based on multiple factors, such as on-chain interest rates, capital utilization, overall market conditions, and more, and will adjust dynamically as market conditions change.
Morpho USDC Earn: Institutional-grade vault management with funds allocated to compliant borrowers. Earnings grow automatically with interest, with an approximate APY of 3.79%.Morpho USDT Earn: Efficient matching via smart algorithms; all loans are fully collateralized. Earnings fluctuate with market demand, with an approximate APY of 3.58%.Sky USD Earn: Backed by U.S. Treasuries and on-chain credit businesses. Deposit certificates are accumulative assets whose value increases over time, with an approximate APY of 4.5%.Ethena USDe Earn: Based on a spot-perpetual arbitrage strategy, designed for steady growth, with an approximate APY of 5.1%.
Actual APYs are subject to market fluctuations; the above figures are for reference only.
This update complements BenPay DeFi Earn’s existing investment targets—such as AAVE, Compound, and Solana—by covering multiple yield mechanisms to meet diverse risk preferences and asset growth needs. Through a single unified interface, BenPay, users can complete cross-chain transfers, deposits, and redemptions, simplifying on-chain participation and complexity while ensuring full asset traceability and true user control.
In the future, BenPay will continue to expand high-quality DeFi options, focusing on the three core pillars—protocol security, on-chain transparency, and capital efficiency - to continuously refine its products and user experience.

Selon Chainalysis, en 2025, plus de 3,4 milliard de dollars de cryptomonnaie ont été volés, et le nombre de vols de portefeuilles personnels a augmenté à 158 000 cas, principalement en raison de fuites de clés privées et de problèmes liés aux plateformes centralisées. Alors que les portefeuilles cryptographiques évoluent pour devenir davantage des plateformes intégrées pour les paiements, la répartition des actifs et le rendement, les cartes de rendement sur chaîne attirent de plus en plus d'attention.
Pour les nouveaux utilisateurs, la question la plus pressante reste : une carte de rendement sur chaîne est-elle sûre ? En résumé, il n'existe pas de réponse absolue à la question de savoir si elle est « entièrement sûre » ou « entièrement instable ». Leur sécurité dépend principalement de trois facteurs : si les fonds sont auto-gérés, si les rendements sont vérifiables sur la chaîne, et si les fonds peuvent continuer à générer des rendements tout en restant pleinement disponibles pour les paiements.

Introduction
Pour la plupart des détenteurs d'actifs numériques, les fonds finissent généralement dans l'un des trois endroits - et chacun présente des défauts clairs :
Conservés sur un compte d'échange : Pratique à utiliser, mais les actifs sont sous garde. La sécurité et la transparence restent des préoccupations constantes, et les fonds ne génèrent généralement aucun rendement.
Stockés inactifs dans un portefeuille : Les actifs sont sécurisés, mais simplement « stockés », sans participer aux opportunités de rendement en chaîne.
Déposés dans des protocoles DeFi : Un rendement est possible, mais le processus est complexe, et les risques sont difficiles à prédire. Une fois les fonds déployés, il est souvent difficile d'y accéder pour les dépenses quotidiennes.

For Web3 payments to truly enter the mainstream, it is essential not only to address issues of "efficiency and cost" but also to restore users' control over the "privacy boundaries of their digital identities." In other words, privacy is a prerequisite for payments to achieve mass adoption, not merely an optional technical enhancement.
BenFen Chain’s private payment system is designed precisely to address this core challenge. Built on the BenFen Chain ecosystem, BenPay (www.benpay.com) enables users to leverage the BenPay Card for daily small-value payments—such as dining, subscriptions, transportation, and online purchases—making stablecoin payments more accessible and seamlessly integrated into everyday life. The system uses advanced MPC technology to automatically conceal transaction details, including amounts, times, recipient information, and address correlations across transactions. Additionally, BenFen Chain introduces a "selective disclosure mechanism" that allows users to grant limited transaction visibility to merchants or regulators when necessary, enabling a "verifiable yet untraceable" payment experience.

As crypto payments move closer to everyday use, crypto cards have become a practical tool for cross-border spending, ad payments, and premium subscriptions. Yet one long-standing problem remains unresolved: Money sitting in a card account does nothing until it is spent. This inefficiency is exactly what an on-chain yield card is designed to solve.
In this guide, we’ll explain what an on-chain yield card is, how Earn While You Spend works in practice, the security and self-custody model behind it, real-world implementation examples (BenPay), and who this product is best suited for.
What Is an On-Chain Yield Card?
An on-chain yield card is a crypto payment card that enables the card account balance to participate in on-chain earnings after the "Earn" button is activated by the user. In simple terms: An on-chain yield card = a crypto payment card combined with an on-chain yield mechanism based on the balance of the card account
Unlike traditional crypto cards, where balances sit idle until spent, an on-chain yield card ensures that unused funds continue to work and generate on-chain yield in the background.
Key Differences from Traditional Crypto Cards

Users do not need to manually participate in DeFi or understand complex DeFi protocols. After activating the "Earn" button, as long as the funds remain in the card account, they can continuously generate on-chain returns.
How “Earn While You Spend” Works
Card Account Balance-Based On-Chain Yield Model
In an on-chain yield card, Earn While You Spend refers to a card account balance-based on-chain yield mechanism, not transaction-based rewards. Instead of earning from each payment, users earn an on-chain yield from the unspent portion of their card account balance.
Here’s how it works in practice:
Card Account Balances Remain On-Chain
When users top up stablecoins into an on-chain yield card, those funds are held in an on-chain wallet linked to the card. Before being consumed, the balance of the card account remains on the chain, enabling it to be compatible with smart contracts and on-chain yield protocols. The card itself is merely a payment interface, not an asset custodian.
Idle Funds Are Automatically Allocated to Yield
Any portion of the card account balance that is not immediately spent is considered idle funds. After users activate the "Earn" function, these idle funds are allocated into high-liquid, relatively low-risk on-chain yield strategies.
After starting to "earn", the entire process is automated for users:
No manual depositsNo complex DeFi knowledge required
From the user's perspective, the card account balance will continue to accrue on-chain yield during the period the "earn" is active.
Spending Does Not Interrupt Earning
A key feature of the Earn While You Spend model is that earning and spending happen simultaneously. When a user makes a payment:
The amount spent will be deducted from the card balanceThe remaining balance in the card account will continue to generate incomeThe funds in the card account can always be used immediately
For example, if a user tops up 1,000 USDT to the card account and spends 300 USDT on the card, the remaining 700 USDT in the card account will continuously generate on-chain income until it is spent.
Not Cashback, Not Rewards
It’s important to clarify that this model is fundamentally different from cashback or reward cards.
Yield is not generated by spendingThere are no per-transaction incentivesEarnings come from time and the balance size of the card account, not from usage frequency
Yield accrues as long as funds remain in the card account. The longer funds remain in the card account, the more yield they generate—without affecting the user’s ability to spend.
Therefore, the true meaning of "earn while you spend" is that users do not have to choose between "using funds" and "letting the funds make money." They can consume freely while allowing the remaining balance in their card accounts to continuously participate in on-chain yield in the background.
Security and Self-Custody
Security is the foundation of any on-chain financial product.
Self-Custodial Architecture
Most mature on-chain yield cards adopt a self-custodial architecture, meaning:
Users retain full control of their assetsThe platform does not freely move user fundsAsset states can be verified on-chain
In practice: The card is a spending interface, not a custodian of assets.
Yield Strategies Designed for Liquidity
Unlike aggressive DeFi investments, yield strategies behind on-chain yield cards prioritize:
High liquidityAbility to withdraw funds at any timeCapital preservation over maximum APY
The objective is not yield maximization, but: Stable, uninterrupted earnings while maintaining spendability
Clear Risk Boundaries
An on-chain yield card is:
Not risk-freeBut it has a significantly lower risk than active DeFi investingComparable to an “on-chain money market” experience
This balance makes it suitable for users who want yield without complexity.
Real-World Implementation Example: BenPay On-Chain Yield Card
To illustrate how an on-chain yield card works in practice, consider the BenPay On-Chain Yield Card (mentioned purely as an example).
Users top up stablecoins (USDT/USDC) to card accounts for daily spendingUnused card account balances will automatically participate in on-chain yield after the user actively activates the earn functionDaily earnings are visible, such as: “Yesterday’s yield: +2 USDT”No additional action is required, and spending remains seamless

The key innovation is not high yield, but changing the default state of card account balances from "idle funds" to "on-chain assets that can generate value". This transformation has also fundamentally changed users' perception of card account balances: the money in the card account is no longer just temporary consumption funds, but a continuously operating asset.

No. Spending and earning on-chain yield can happen simultaneously.
Do I need Complex DeFi knowledge?
No. Users only need to enable the earn function independently. The subsequent on-chain interest generation process will be automatically executed by the system, and users do not need to perform any DeFi operations.
Is it risk-free?
No on-chain product is risk-free, but risk is significantly lower than active DeFi.
Is it meant for long-term investing?
It’s best for idle balances used for spending and storage—not high-risk investing.
Final Thoughts
The On-Chain Yield Card is not merely for obtaining earnings. Its true value lies in solving the problems of idle funds and inefficient use, allowing your assets to continuously increase in value through consumption and payment. By turning idle balances into productive assets, it transforms a crypto payment card into a value-generating financial interface, bridging everyday spending and on-chain finance in a way that feels natural, simple, and sustainable.

Risk Notice
On-chain yield cards are not risk-free. Funds are exposed to on-chain protocols, smart contract risks, and market fluctuations. Users should understand that earnings are not guaranteed. Always review platform terms and consider potential losses before using them.

In the traditional financial world, earning interest on savings typically means depositing funds in a bank and accepting relatively low rates. In the decentralized finance (DeFi) space, however, anyone can become their own "bank" by depositing cryptocurrencies into on-chain protocols to directly access higher-yielding assets. If you're curious about "DeFi earnings" but unsure where to start, this article provides a clear, secure beginner's guide, along with an introduction to how innovative platforms like BenPay can help you take your first step with ease.
What is DeFi Yield?
In simple terms, DeFi earnings refer to the interest or rewards users receive by depositing cryptocurrency assets (such as stablecoins like USDC and USDT, or mainstream tokens) into top DeFi protocols. This DeFi earnings model is typically presented as an APY (Annual Percentage Yield). These protocols function like automated "digital banks," pooling the deposited assets for activities such as lending, trading, or other on-chain operations, and returning the majority of the generated profits to the users who provided the assets.
DeFi Yield VS. Traditional Finance
Compared to traditional finance, the core advantages of DeFi earnings lie in：
No intermediaries: No banks or institutions act as middlemen, reducing costs.Global and open access: Anyone with an internet connection can participate.Transparency: All transactions and interest rates are publicly verifiable on the blockchain.Potentially higher returns: Under specific market conditions, certain DeFi protocols may offer annualized yields higher than traditional savings rates, though returns can fluctuate with market movements.
Three Major Challenges for Beginners Participating in DeFi Earnings
While the prospects are enticing, newcomers often encounter the following obstacles when entering the DeFi world directly:
High Technical Barriers: Managing wallet private keys, understanding gas fees (transaction costs), and interacting with complex DApp interfaces.Insufficient Risk Awareness: Including risks such as smart contract vulnerabilities, market volatility, and inherent design flaws in protocols.Cumbersome Operations: Processes like identifying high-yield protocols, transferring assets across chains, and frequently optimizing returns are incredibly time-consuming.
Risk Notice for DeFi Earnings (Must-Read for Beginners)
DeFi earnings are not risk-free products. Users should fully understand the following risks before participating:
Smart Contract Risk: Even leading protocols may have undiscovered vulnerabilities.Market Risk: APY fluctuates with market liquidity and interest rate changes.Stablecoin Risk: Stablecoins are not bank deposits and are not protected by deposit insurance.

Want to earn passive income with crypto but feel overwhelmed by complex DeFi protocols, high gas fees, and security risks? You're not alone. The promise of DeFi earnings is compelling, but the path to getting started is often riddled with technical barriers. This guide breaks down exactly how passive income with DeFi works in 2025 and introduces a simplified, secure way to generate yield—without needing to become a blockchain expert overnight.
What is Passive Income in DeFi (And Why It Matters)
In the traditional financial world, passive income might come from rental properties or stock dividends. In decentralized finance (DeFi), it refers to the yield or interest your crypto assets can earn simply by being put to work on the blockchain.
Understanding On-Chain Yield vs. Traditional Savings
When you deposit money in a savings account, the bank lends it out and gives you a small fraction of the interest. DeFi flips this model. By using smart contracts, you can directly lend your assets to others, provide liquidity for trading pairs, or stake in secure networks. In return, you earn a yield, often significantly higher than traditional banks, because you're cutting out the middleman. This is the core of earning from DeFi.
The Rise of Accessible DeFi in 2025
The narrative has shifted. DeFi crypto earn opportunities are no longer just for technical traders. In 2025, the focus is on accessibility, user experience, and integrated security. Products are being built to abstract away the complexity, allowing anyone with a smartphone to tap into the potential of on-chain stablecoin yield and other earnings.
The Main Challenges for Beginners Wanting DeFi Earnings
The potential is vast, but the initial hurdles are real. Here are the key pain points new users face:
Why Is DeFi So Complicated for New Users?
Complexity and Technical Barriers
Navigating a DeFi staking platform or liquidity pool requires understanding wallets, transactions, approvals, and concepts like impermanent loss. One wrong click can lead to lost funds. For someone looking for simple best DeFi earnings, this learning curve is the biggest deterrent.
Is DeFi Passive Income Safe?
Security Concerns and Protocol Risks
The "do your own research" (DYOR) mandate is heavy. Beginners must audit smart contract code, assess team credibility, and monitor for exploits. The fear of placing funds into a fraudulent or poorly audited protocol is a significant barrier to starting DeFi crypto earn activities.
Do Gas Fees Reduce DeFi Profits?
High Gas Fees That Eat Into Profits
Every transaction on a blockchain—depositing, claiming rewards, withdrawing—costs a "gas" fee. For smaller investments, these fluctuating fees can completely erase any profit, making earning interest on crypto strategies inefficient.
