PANews reported on August 8 that Illia Polosukhin, co-founder of the public chain project NEAR Protocol, said on the X platform that Chain Signatures has been launched on all mainnets. This is a big step towards chain abstraction: Chain Signatures enables NEAR Protocol smart contracts to sign transactions on any blockchain. Previously, we faced the problem of liquidity fragmentation in DeFi, and now all chains will share a decentralized financial layer. No more dozens of wallets and addresses, no more manual cross-chain bridging, and no more gas fees on the tokens of each chain. Instead, all applications can be accessed no matter where the user is, and applications are fully multi-chain compatible from day one. Developers can also program more logic directly into their smart contracts.
