COTI confirmed that the gcEVM implementation, based on Garbled Circuits, has been live on mainnet since March 2025 and has processed more than 125 million transactions on-chain.
COTI launched Nightfall in its internal testnet phase, the first decisive step on the path toward deployment on the Ethereum mainnet. The protocol, based on an open-source ZK Roll-up architecture originally developed by Ernst & Young in 2019, is designed for regulated and institutional environments that require transaction privacy without sacrificing transparency or auditability.
COTI introduced its “Private DeFi” framework as the category that, according to the company, will define the future of decentralized finance. Its central argument is that the full transparency of public blockchains exposes the balances, transactions and strategies of any user, representing a real cost for individuals, institutions and artificial intelligence agents operating on-chain.
COTI and Midnight Foundation have entered a strategic partnership aimed at expanding privacy-focused infrastructure across the blockchain sector. The collaboration will focus on interoperability, privacy standards, research initiatives, and developer tools.
Carbon DeFi launched its MCP server on the COTI network, allowing artificial intelligence agents to deploy and manage automated trading strategies directly on-chain. The server grants access to 25 tools covering six strategy types: Limit Orders, Range Orders, Recurring Strategies, Concentrated Liquidity, Full Range Liquidity, and Swaps, with no manual configuration required from the user.
COTI added Whisper, a confidential prediction market, as a new grant recipient within its privacy ecosystem. Whisper emerged from the COTI Vibe Coding Challenge, where it placed second and received a 25,000-token prize for its proposal. The platform encrypts users' on-chain positions using Garbled Circuits and operates with pUSDC as its betting currency.
COTI launched the Privacy Portal, a web app that converts public tokens into private ones with a single click on its network. The platform supports seven assets and fees are paid using its native token. The system is non-custodial, operates entirely on-chain and uses the Garbled Circuits technology developed by the protocol.
COTI solved Yao's ‘Millionaires Problem' on Ethereum's Sepolia testnet using Garbled Circuits with no trusted intermediaries. The solution was developed with Soda Labs, is live on mainnet, and is compatible with the EVM environment and Solidity. Vitalik Buterin had publicly identified Garbled Circuits as the path toward purely cryptographic guarantees in multiparty computation.
COTI launched Private ERC20, an ERC20-compatible token standard that encrypts balances, transfers and approvals at the protocol level. It uses Garbled Circuits and an MPC precompiler to ensure only the token holder can decrypt their own balance. The standard was audited by Sayfer and is already available on the COTI network.
COTI announced a partnership with Sayfer, a Web3 cybersecurity firm with zero recorded hacks among its clients since its founding in 2019. Sayfer completed several independent audits of the smart contracts behind COTI's private ERC-20 tokens and the upcoming Privacy Portal. The firm joins as a long-term security advisor.
