The Near Foundation has unveiled Chain Signatures, a groundbreaking protocol designed to streamline transaction signing across multiple third-party blockchains using a single Near account. Currently operational on Near's testnet, Chain Signatures is slated for a mainnet release in early May, as confirmed by a Near spokesperson. Powered by a decentralized multi-party computation (MPC) network and bolstered by Near network validators, Chain Signatures empowers Near accounts, including smart contracts, to execute transactions on any blockchain. This revolutionary capability allows Near accounts to manage numerous addresses across all blockchains, paving the way for innovative decentralized finance (DeFi) applications. In the near future, Chain Signatures will benefit from additional security measures provided by EigenLayer, as outlined by the foundation. The Near Foundation expressed enthusiasm about the prospects of decentralized finance (DeFi) on non-smart contract chains, highlighting the newfound feasibility on various networks, including Bitcoin. This breakthrough opens avenues for developers to seamlessly create DeFi products utilizing assets from disparate chains without the need for asset bridging mechanisms.
