Key Takeaways

The Usual Protocol is a decentralized finance (DeFi) project that aims to make real-world assets (RWAs) more accessible to everyday users.

It addresses issues with existing stablecoins, including profit centralization and lack of transparency.

The Usual ecosystem has three main tokens: USD0, a stablecoin backed by real-world assets, USUAL, a governance token, and bUSD0, a liquid staking token that represents staked USD0, allowing users to earn rewards while keeping liquidity.

Introduction

Stablecoins are one of the most widely used tools in crypto. They let users hold value without worrying about large price swings, and they help connect traditional finance with decentralized finance. But most popular stablecoins have a hidden problem: the companies that issue them keep most of the revenue.

The Usual Protocol was created to change this dynamic. It introduces a stablecoin ecosystem where users share in the value they help create. This article explains how Usual works, what its tokens do, and why it was built.

What Is the Usual Protocol?

The Usual Protocol is a blockchain-based project that uses real-world assets (RWAs) as collateral to back its stablecoin. Instead of keeping all the revenue from this model, Usual redistributes value back to the people who use the protocol.

At its core, Usual has three tokens working together: USD0 (the stablecoin), bUSD0 (a liquid staking token), and USUAL (the governance and reward token). Together, these create a system where users are not just customers but actual stakeholders in the protocol.

The protocol is designed to be transparent and verifiable. Collateral details can be checked on-chain and through regular public audits, giving users greater confidence in what backs their stablecoins.

Core Components of the Usual Protocol

USD0: the stablecoin

USD0 is Usual's native stablecoin. It is backed 1:1 by short-term, low-risk assets like U.S. Treasury bills, which makes it fully collateralized.

Users can mint USD0 by depositing approved collateral directly. For those who cannot hold certain asset types, the protocol's DAO can assist with minting and then redistribute USD0 back to them.

To keep USD0 secure, the protocol only accepts collateral that meets strict standards. This includes full backing without leverage, high liquidity so assets can be sold quickly if needed, and regular transparent audits.

bUSD0: the liquid staking token

bUSD0 is Usual's liquid staking token. It represents USD0 that has been locked into the protocol for a four-year period.

When users stake their USD0, they receive bUSD0 in return. This token can still be traded on secondary markets, so users do not lose full access to their funds while they earn staking rewards.

USUAL: the governance token

USUAL is the governance and reward token of the Usual Protocol. It is used to vote on protocol decisions and to reward users who contribute to the ecosystem.

USUAL tokens are minted based on the protocol's revenue, not a fixed schedule. This ties the token supply to actual activity and growth, which can help with long-term sustainability.

Holders can stake USUAL to earn additional USUAL tokens. They can also vote on important protocol decisions, such as which assets to accept as collateral and how rewards are distributed.

Why Was Usual Created?

Traditional stablecoin providers generate billions of dollars from the yield on their collateral assets. This revenue rarely flows back to users. Usual was built to address this imbalance.

The protocol also aims to fix limited access to RWAs and improve transparency. By putting collateral information on-chain and making it publicly auditable, users can verify for themselves what backs the stablecoins they hold.

Looking ahead, Usual plans to expand its product range with a yield optimizer, fixed-rate products, and fixed-term instruments. These are intended to give users more ways to interact with the protocol.

Governance and Decentralization

When Usual first launched, the protocol was overseen by Usual Labs to ensure a smooth rollout. Over time, governance has been transitioning to the Usual DAO, where USUAL holders collectively make decisions.

Governable aspects include which assets are accepted as collateral, how the treasury is allocated, and how reward structures are adjusted. This gives the community direct input into the direction of the protocol.

FAQ

What makes USD0 different from other stablecoins?

USD0 is backed by real-world assets like U.S. Treasury bills rather than cash held at a bank. It is permissionlessly mintable, meaning anyone with approved collateral can create it, and its collateral details are publicly auditable.

Is bUSD0 the same as USD0++?

bUSD0 is the current name for the liquid staking version of USD0, previously known as USD0++. It represents staked USD0 locked for a four-year period and can be traded on secondary markets while earning staking rewards.

How does the Usual Protocol redistribute value to users?

The protocol redistributes value primarily through USUAL tokens, which are minted based on revenue and distributed to users who provide liquidity or stake their assets. This means users share in the economic upside of the protocol rather than having it captured by a central issuer.

Can I lose my funds if collateral values drop?

The Usual Protocol uses strict collateral standards, including low-risk, fully backed assets with high liquidity. It also maintains an insurance fund to address potential collateral losses. However, all DeFi protocols carry risk, and users should research thoroughly before participating.

Closing Thoughts

The Usual Protocol offers a different approach to the stablecoin model. By combining real-world assets with a multi-token system and a community governance model, it aims to give users more transparency, access, and a share of the value they generate.

Its three-token system (USD0, bUSD0, and USUAL) works together to support stability, reward long-term participation, and enable community-driven decision-making. Whether the model succeeds at scale will depend on how the protocol evolves and how users engage with it over time.

Key Takeaways

Bonding curves are mathematical models that link a token's price directly to its supply, forming the basis of many tokenomics systems in crypto.

As more tokens are purchased, the price tends to rise; as tokens are sold, the price tends to fall. This relationship is automated and governed by a smart contract.

Common bonding curve shapes include linear, exponential, logarithmic, step-function, and S-curve models, each producing different pricing dynamics for buyers at different stages.

Bonding curves carry risks including price manipulation, exit liquidity challenges, and token volatility. They do not guarantee any level of stability or return.

Introduction

A bonding curve is a mathematical model that automatically adjusts a token's price based on its circulating supply. It's a core mechanism in crypto tokenomics that removes the need for a centralized order book by using a formula encoded in a smart contract to handle buying, selling, and pricing.

The concept builds on a simple principle: as demand grows and more tokens are purchased, price rises; as tokens are sold and supply decreases, price falls. This creates a predictable, transparent pricing mechanism that operates automatically without human intervention.

Bonding curves are used in token launches, decentralized exchanges, governance systems, and other applications across the crypto ecosystem. Understanding how they work can help you evaluate projects that rely on this pricing model.

What Are Bonding Curves?

Bonding curves are mathematical models that create a direct relationship between a token's price and its total supply in circulation. A predefined formula, stored in a smart contract on a blockchain, calculates the current price at any given supply level.

When someone buys tokens, new tokens are minted and added to the supply. When someone sells, tokens are burned and removed from supply. The smart contract adjusts the price automatically with every transaction, ensuring that pricing is always consistent with the formula and cannot be manipulated by a third party.

This is similar to how supply and demand work in traditional markets. When demand outpaces supply, price tends to rise. Bonding curves apply this logic in a programmable, automated way, making pricing rules transparent and enforceable by code.

How Do Bonding Curves Work?

The core mechanic is straightforward. A smart contract holds a reserve of funds (such as ETH or SOL). When a buyer purchases tokens, the funds go into the reserve and new tokens are issued at the current price. When a seller returns tokens, the contract burns them and releases the corresponding funds from the reserve.

The price at any point is determined by the bonding curve formula. Early buyers pay lower prices because supply is still low. Later buyers pay higher prices as supply grows. This structure often rewards early participants, though it also exposes them to higher risk if the token fails to attract sustained demand.

Projects can customize the shape of the curve to produce different pricing behaviors. The most common types are linear, exponential, logarithmic, step-function, and S-curves.

Linear bonding curves

A linear bonding curve increases the price by a fixed amount for each new token added to supply. Price growth is steady and predictable, making linear curves easier to understand for new buyers.

Exponential bonding curves

In an exponential curve, the price increases faster as supply grows. Each additional token costs significantly more than the last, which means early buyers can see substantial gains if demand continues to grow. Projects that want to strongly reward early participation may use this model. However, the rapid price acceleration also means later buyers pay much more.

Logarithmic bonding curves

A logarithmic curve starts with rapid price increases as early tokens are bought, but the rate of increase slows as supply expands. This tends to benefit the earliest buyers most, while providing more price stability for later participants once the initial surge settles.

Other curve types

Beyond these three common shapes, projects also use step-function curves, where price increases at specific milestones rather than continuously, and S-curves, which combine initial slow growth, a rapid middle phase, and eventual stabilization. Inverse bonding curves work in the opposite direction, with prices starting high and decreasing as more tokens are issued.

Practical Use of Bonding Curves

Bonding curves are widely used in decentralized finance (DeFi) for token launches and automated pricing. One of the most visible examples is pump.fun, a token launch platform built on the Solana blockchain.

Pump.fun allows users to create and distribute tokens, most commonly meme coins, using a bonding curve to manage all pricing and liquidity automatically. When a new token is created, the bonding curve sets the starting price and controls how it changes as tokens are bought and sold. There is no need for an external market maker or centralized price feed.

As buyers purchase tokens, the curve tracks progress toward a predetermined market cap target. Pump.fun displays this as a visual percentage bar in its interface. 

Once a token reaches its market cap milestone, the platform automatically pairs the SOL raised through the bonding curve with the token supply to create a trading pool on Raydium, a Solana-based exchange. At that point, the bonding curve mechanism is retired and open market trading takes over.

This graduation process bridges bonding curve mechanics with traditional liquidity pools.

Risks and Limitations of Bonding Curves

While bonding curves provide transparency and automation, they carry significant risks. Unlike a traditional automated market maker (AMM) that relies on external liquidity providers, a bonding curve's reserve is funded entirely by buyers. If demand drops sharply, sellers may face limited exit liquidity, especially in early-stage tokens with small reserves.

Bonding curves can also be susceptible to price manipulation. Large purchases inflate the price quickly due to the curve's formula, allowing early buyers to sell at significantly higher prices than later participants paid. This dynamic is sometimes exploited in coordinated schemes designed to profit at the expense of later buyers.

Token volatility is an additional concern. Because bonding curve prices respond directly to buying and selling activity, even small changes in demand can produce large price swings. Projects using bonding curves do not guarantee any level of stability, and token values can decline to near zero if interest wanes.

These risks don't mean bonding curves are inherently flawed. They are a useful tool for automating token pricing and distribution. But understanding the mechanics helps users make more informed decisions when participating in bonding curve-based projects.

FAQ

What is a bonding curve in crypto?

A bonding curve is a mathematical formula encoded in a smart contract that automatically sets a token's price based on its circulating supply. As more tokens are purchased, the price increases; as tokens are sold, the price decreases. The contract handles all buying, selling, and pricing without human intervention.

Why do early buyers benefit from bonding curves?

Early buyers purchase tokens when supply is low, so they pay lower prices based on the curve formula. If demand grows and more tokens are bought, later participants pay higher prices. Early buyers can sell their tokens at these higher prices, potentially earning a return. However, this also means early buyers take on more risk if the project doesn't attract sustained demand.

How does pump.fun use bonding curves?

Pump.fun uses bonding curves to manage token pricing and liquidity automatically on Solana. When a new token is created, the curve controls price changes as tokens are bought. Once the token reaches a target market cap, the platform transfers the raised SOL and token supply to Raydium to create an open liquidity pool. The bonding curve is then retired and standard market trading begins.

What are the main risks of bonding curves?

Key risks include exit liquidity problems (the reserve may be insufficient if many sellers exit at once), susceptibility to price manipulation by large buyers, and significant token price volatility. Bonding curves do not guarantee stable prices or any level of return. Users should research any bonding curve project carefully before participating.

What is the difference between a bonding curve and an AMM?

Both bonding curves and automated market makers automate token pricing. An AMM relies on external liquidity providers who deposit paired assets into a pool, while a bonding curve funds its reserve directly from buyers of the token. AMMs typically operate after a token is already trading on a decentralized exchange, whereas bonding curves are often used at the token launch stage before open market trading begins.

Closing Thoughts

Bonding curves bring an automated, transparent approach to token pricing by encoding supply-and-demand dynamics directly in smart contract code. They have become a foundational tool in DeFi, enabling projects to launch tokens and manage liquidity without centralized intermediaries.

Platforms like pump.fun have demonstrated how bonding curves can work at scale, processing large volumes of token launches and transferring liquidity to open markets automatically. At the same time, the risks of manipulation, exit liquidity shortfalls, and token volatility should be considerations for anyone participating in bonding curve-based systems.
