Deploy private smart contracts on COTI, or plug COTI privacy into the chain you already use.
A high-performance network for private smart contracts. Write in Solidity, encrypt what matters, and settle in seconds.
Keep your app, accounts and assets on the EVM chain you already use. COTI runs the private computation and returns an encrypted result only you can read.
Live on Avalanche
Since September 16, apps on Avalanche can compute on confidential data in production, allowing users and developers to shield AVAX and USDC directly through the Privacy Portal
Read the announcementCOTI is a groundbreaking blockchain network designed to enable computation on encrypted data through the use of Garbled Circuits. By combining advanced cryptographic techniques with blockchain technology, COTI opens new possibilities for secure and private data processing.
How much do I have to relearn?
Almost nothing. If you build on Ethereum, you already know how to build on COTI, with the same Solidity, Foundry, Hardhat, viem, ethers.js and MetaMask. Privacy comes from COTI's private data types, which work like the ones you already use and run on garbled circuits.
Features
What can I build with it?
Any app that handles money or personal data eventually needs privacy. With COTI, you add it to the product you already have, and your users never have to switch chains or wallets.
Features
Who gets to see what?
You decide. Data stays encrypted by default, but your contracts can still use it, and you can grant access to specific people for a specific time.
Features

Our mission
We believe the world's money will soon move the way information does, on open networks. But those networks are public, and nobody wants to run their finances in public.
COTI is the privacy network for programmable money. We enable financial institutions, businesses, developers and individuals to hold, move and settle value on public blockchains confidentially, helping bring real-world finance on-chain.
Our institutional-grade technology has been developed across the European Central Bank, the Bank of Israel, Avalanche, Input Output and the Cardano Foundation, and built since 2017 toward a single idea: private money as the standard.
“COTI gives individuals, businesses and institutions a way to transact on public blockchains without transacting in public.”
