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.
