Introduction
Private DeFi is here. It’s live and running on COTI.
DeFi reinvented how value moves. Lending, stablecoins, trading, liquidity. All without a middleman with every transaction posted across public blockchains anyone can verify. It became one of the largest engines in Web3. But a missing piece was exposed as DeFi attempted to scale: Privacy.
On a public blockchain, your balances, your trades, and your positions are exposed by default. Every move is visible to competitors, threat actors, bots, and to anyone watching the chain. In addition, privacy is a human right. Every individual has a right to protect their data, wallet amounts and transactions.
Privacy needs to meet builders, projects, and users where they already are. That means privacy native to the standards the whole ecosystem runs on and available to be used by users and builders where they already are.
That is what COTI delivers. Privacy built in and programmable across the entire DeFi stack.
COTI Private DeFi: Built Different
Plenty of projects talk about privacy. COTI built the fastest and most flexible version of it for real applications. Three things set it apart.
Fully programmable privacy. Privacy on COTI is not a single fixed feature. While COTI enables Private ERC20 tokens, it’s not limited to just private tokens and balances.
Builders decide what stays encrypted and what stays public, at the function level, and can tighten privacy as a product matures. The flexibility that made smart contracts powerful now applies to confidentiality.
Selective disclosure for compliance. Confidential does not mean unaccountable. COTI supports selective disclosure, so the right information can be revealed to the right party, like an auditor or a regulator, without broadcasting it to the entire world. Privacy and compliance work together, so it can scale globally and legitimately.
The fastest, lightest, and most cost-effective privacy in Web3. COTI runs on Garbled Circuits, a cryptographic protocol for secure multi-party computation (MPC). It is up to 3,000x faster and 250x lighter than alternative privacy solutions. Privacy that is too slow or too expensive does not get used. COTI made it fast and cheap enough to power real DeFi at scale.
Here is the difference, side by side.
The COTI Private DeFi Stack
Private DeFi is not one product. It is a full stack of privacy-enabled building blocks, each one designed to work together. Here’s what’s live & what’s next:
Private ERC20 Tokens: Live now
At the base of the stack sits Private ERC20 tokens. COTI’s privacy-enhancement to the leading token standard in the world. It behaves exactly like the ERC20 you already know. Hold it, send it, receive it, approve it to a contract, and build DeFi around it.
The difference is in the data: balances, transfer amounts, and allowances are all encrypted on-chain. Each holder has their own encryption key. Only you can decrypt your balance. Everyone else, including validators, sees ciphertext.
Your assets, with Privacy On, and your balance visible only to you. Supported private assets already live on COTI Network include COTI, USDT, USDC.e, wETH, wBTC, wADA, and gCOTI. It is live and enabled in MetaMask, the world’s number one wallet, with support expanding to more wallets soon.
Today, anyone can mint a Private ERC20 token on COTI. Any ERC20 can easily become a Private ERC20 on COTI Network and any other EVM chain. I If you can write an ERC20, you can write a Private ERC20.
The Privacy Portal: Now Live
If Private ERC20 is the foundation, the Privacy Portal is the gateway. It is where you turn Privacy On.
The Portal is a simple web app and the control surface for privacy. Bring a public token in, send a private one out. In a few clicks you can shield a supported public token into its private version, then hold it, send it, and receive it on-chain, and make it public again whenever you choose.
The Privacy Portal will serve as the onramp to the private DeFi ecosystem powered by COTI. The Privacy Portal is easy to use, lightning fast and low cost, designed to be multichain, supporting a wide variety of tokens & stablecoins.

Private NFTs: Live now
The same privacy primitives extend to non-fungible assets. On COTI you can create, mint, and transfer private ERC-721 NFTs, with ownership kept confidential. The COTI MetaMask Snap already lets you sync, import, and view private NFT metadata and images directly in your wallet.
This opens the door to privacy-preserving digital collectibles, identity credentials, access tokens, and more.
PriveX: Private Perps DEX
Trading is where privacy matters most. Whales get hunted, wallets get exposed, positions are exposed and larger transfers are vulnerable.
PriveX, the first perpetual DEX built on COTI, will soon be launching private trading. Imagine privacy powered- perps and spot trading for humans and agents. Where asset amounts and balances stay encrypted, protecting strategies.
PriveX has already processed over $20 billion in total trading volume, and uses intent-based execution to keep strategies confidential. The first private Perps DEX is almost here.
Private RWAs
Real-world assets are the next great migration on-chain, a market projected to reach $30 trillion. The blocker has always been transparency. Institutions will not put proprietary deal structures, counterparty identities, and transaction volumes on a public ledger, which is why most enterprise RWA deployments stay stuck on private, permissioned chains.
COTI changes that. Together with Zoniqx, the AI-native operating system for tokenized real-world assets, COTI powered the world’s first privacy-enabled RWA on testnet. Issuance, transfers, and settlement stay encrypted end to end, with selective disclosure for regulators and auditors, so issuers get global liquidity while keeping sensitive financial data private.
Private RWAs are moving from testnet toward mainnet as Zoniqx onboards issuers across asset classes and jurisdictions, opening a world of RWA Private DeFi.
Private AI Agents: Live Now
Agents are quickly taking over onchain: trading, paying, and coordinating around the clock. Without privacy, every agent action can leak its strategy, its logic, and the sensitive data it touches.
COTI brings privacy to the agent economy. AI Agent skills and MCP (Model Context Protocol) support are live on COTI Network, so agents can transact and compute on encrypted data without exposing positions, credentials, or proprietary logic.
AI Builder Tools and MCP: Live Now
You should not need a cryptography degree to build with privacy.
COTI’s AI builder tools and MCP server make it simple to add COTI privacy to an app or an agent, mint private tokens, build with private tokens and more. Any builder, including vibe coders, can now build the next generation of Private DeFi.
COTI Private DeFi on Multiple Chains
The COTI Private DeFi stack does not stop at COTI’s own network. The same building blocks are designed to expand across the crypto-verse.
Privacy-on-Demand brings Garbled Circuits powered privacy to any chain, token, and app. It starts with Ethereum and leading L1s and L2s, with more chains to be announced.
The plan is to bring COTI’s full privacy & private DeFi stack to leading EVM chains, projects and tokens. While enabling builders and users to access privacy on the platforms, wallets, and tools they already use.
What You Can Build with COTI Private DeFi
Put the full-COTI privacy stack together and a new category of applications becomes possible.
Private Tokens: Turn any public ERC20 into a private token. Balances and transfers encrypted.
Private Stablecoins: Shield, store, send and receive private stablecoins.
Private Payments: Move value on without broadcasting client info, salaries, invoices, or amounts.
Confidential Lending: Borrow, lend, and provide liquidity without exposing positions.
Private DEXs and Perps: Trade with asset amounts and balances kept confidential.
Tokenized Real-World Assets: RWAs that keep ownership and financial details protected, with selective disclosure for compliance.
COTI MPC enables dynamic and unique Private DeFi applications to be built across a wide-variety of networks. Unlocking Private DeFi use cases including creative new DEXs, new dApps, and apps.
Why This Matters
DeFi proved that open, permissionless finance works. The missing piece was always privacy. Not privacy bolted on as an afterthought, but privacy built into the standard the ecosystem already runs on, fast enough and cheap enough to use everywhere.
COTI’s Garbled Circuits mainnet has already processed over 110 million on-chain transactions, with privacy live in production across DeFi, payments, AI, and real-world assets.
COTI is unlocking a world of Private DeFi. Privacy On, across multiple chains, wallets, apps, tokens and use cases.
Stay COTI.

Build the future of private AI agents. 60 days. 175,000 $COTI in prizes.
Intro to Agent Edition
AI agents are taking over on-chain. The merge of AI and blockchain has arrived, and it’s called Web4.
These agents are predicted to trade trillions and become the primary users of blockchain in the coming years. Billions of intelligent agents will autonomously execute trades, coordinate tasks, manage assets, and make decisions on-chain.
But there’s a problem. Without privacy, every agent’s identity, strategy, and transaction is fully visible. Copy-traded. Front-run. Exploited. The agentic economy can’t scale without highly-scalable, programmable privacy. That’s where you come in.

Public to private. Send private. Private back to public. One wallet. Four clicks.
TL;DR
→ Take a public token on COTI and make it private in one click via the Privacy Portal
→ View and send your private balance directly inside MetaMask through the COTI Snap
→ Convert private tokens back to their public form whenever you choose
→ End-to-end onchain privacy powered by Garbled Circuits
Private Token Loop
COTI has introduced a full-private token lifecycle all within a single wallet. Take a top public token, bridge it to COTI Network and then you can make it totally private. Use the COTI Privacy Portal to make top tokens private in a single click. Hold and send your private tokens with a balance only revealed to you.
Once you’re ready to make your tokens public once again, turn your private tokens back to public in a single click. Easy, simple and all within your wallet.
Here is the full loop in four screenshots.
1. Pick a public token at privacy.coti.io
Open the Privacy Portal and select a public token from the Public Tokens panel. The Portal supports COTI, wETH, wBTC, USDT, USDC.e, wADA, and gCOTI. Choose an amount, click Portal In, and approve the transaction in MetaMask.
2. See your private balance in MetaMask
Once the conversion confirms, your tokens are now private. The balance is encrypted on-chain and visible only to you through the COTI MetaMask Snap. Open MetaMask and your private balance is right there in the wallet you already use, decrypted locally on your device.
3. Send privately from MetaMask
Click Send Token in the Snap, enter a recipient on the COTI Network, and approve the transaction. The transfer is encrypted, on-chain, and confirmed at the lowest cost and fastest speed of any private token transfer, a fraction of a penny in gas.
4. Portal Out back to public
Return to the Privacy Portal, select the private token from the Private Tokens panel, and click Portal Out. Approve the transaction. Your tokens return to their original public form on the COTI Network, fully liquid, fully under your control.
The Power of End-to-End Privacy
Most privacy systems are difficult and challenging to use. Forcing users to decide whether to keep their assets public or private. With COTI, the ease of use is so simple your tokens can easily move between public and private, in an open loop.
Every step happens on the same network, in the same wallet, with the same keys. The Privacy Portal handles the conversion. The COTI MetaMask Snap handles holding, sending, and receiving. Together they give users a complete privacy lifecycle for any supported token, with the option to enter or exit at any moment.
That is what programmable privacy looks like in practice. Not a sealed-off zone, but a switch you control.

Today, we’re excited to announce an official partnership between COTI and Midnight Foundation, an organisation dedicated to advancing the development, adoption, and real-world impact of the Midnight Network, a privacy-first blockchain built by Shieleded Technologies.
Together, COTI and Midnight will collaborate to bridge and broaden the privacy landscape, advance industry standards, and work together to grow a global privacy ecosystem that serves builders, enterprises, and users.
This partnership brings together two of the most prominent privacy protocols in Web3, each with distinct and complementary technology, united by a shared mission: making privacy a foundational layer of blockchain.
What We’re Building Together
This is a strategic alignment between two privacy-native protocols to push the entire ecosystem forward.
COTI and Midnight will actively collaborate on:
Privacy standards development: Joint contributions to best practices and frameworks that define how to build using privacy on-chain.
Cross-chain composability: Enabling the interoperability of our privacy protocols and tokens, unlocking new use cases across both ecosystems.
Builder and enterprise empowerment: Enabling developers and institutions to leverage industry-leading privacy technology from both Midnight’s zero-knowledge architecture and COTI’s Garbled Circuits.
Privacy research and joint marketing: Advancing the shared mission of making privacy mainstream through collaborative research and awareness initiatives.
NIGHT Token Live on the COTI Network
The NIGHT token, Midnight’s native governance token, is already live on the COTI Network. NIGHT token was bridged via ChainPort in January of 2026 (Full Article).
COTI bridged NIGHT to their native network and ecosystem to expand the liquidity and utility for builders, traders, and participants of the Global privacy ecosystem.
The Rise of Midnight
Midnight Network is a next-generation privacy blockchain built by Shielded Technologies. Shielded Technologies is an emerging engineering company pioneering privacy-enhancing, decentralized technologies for real-world adoption. As a spinout from leading web3 venture studio Input Output, the company serves as the core technology partner to the Midnight Foundation, building the foundational infrastructure powering the Midnight network.
Midnight restores the original promise of crypto and aims to be the architecture of freedom. No one should be forced to choose between utility and privacy.
Unlike privacy coins that obfuscate transactions, Midnight combines zero-knowledge cryptography (ZK-SNARKs) with selective disclosure tooling, enabling developers and users to retain privacy where needed while staying compliant and auditable. Its hybrid-ledger design separates public and private data, supporting seamless interactions between transparent and confidential logic.
The NIGHT token launched in late 2025, and Midnight’s mainnet is scheduled for launch in late March 2026.
A Shared Privacy Mission & Philosophy
COTI and Midnight represent two of the most advanced approaches to privacy in Web3.
COTI’s Garbled Circuits deliver high-performance, scalable and cost-effective encrypted computation, fully EVM-compatible, and purpose-built for DeFi, RWAs, and enterprise use cases.
Midnight’s zero-knowledge architecture enables programmable smart contracts where sensitive information remains encrypted end-to-end, yet verifiable, with precise control over data disclosure.
Both COTI & Midnight approach solving the challenges of privacy and pursuing adoption with similar philosophies.
Programmable privacy gives builders and enterprise users selective control over what data is revealed and concealed.
Developer-friendly tooling supporting the creation of privacy-preserving apps with the latest in AI tooling for broader adoption.
Confidentiality as a fundamental feature in DeFi, private payments, identity management, enterprise data protection, and real-world asset tokenization.
The combined capabilities of both protocols is positioned to serve builders and institutions across virtually every category. By aligning together, we’re creating an ecosystem where the rise of privacy benefits everyone.
Why This Matters & What’s Next
Privacy is the single biggest unlock for mainstream blockchain adoption. Institutions will not move sensitive financial data on-chain without confidentiality. Users will not trust systems that expose every interaction. Builders need real privacy tools to create products people actually want to use.
By connecting two of the leading privacy ecosystems, we’re expanding the range of privacy tools available to builders and setting standards that can accelerate institutional adoption.
We’re on a mission to make privacy the default, not the exception. Together with Midnight, we’re moving that vision forward.
About Midnight Foundation
The Midnight Foundation is an organisation dedicated to advancing the development, adoption, and real-world impact of the Midnight network, the privacy enhancing blockchain project developed by Shielded Technologies. Designed for confidential smart contracts, Midnight enables censorship-resistant yet compliant decentralised applications. It leverages zero-knowledge proofs and a cooperative tokenomics architecture — with NIGHT as the utility token and DUST as the shielded capacity resource — to deliver a powerful combination of privacy, security, and decentralization.
