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.
