Inilunsad ng NEAR ang tool para sa pag-sign ng mga transaksyon sa Bitcoin, Ethereum at higit pa
Swiss non-profit organization NEAR Foundation has launched “Chain Signatures,” enabling users to sign transactions on supported blockchains from a single NEAR account. Chain Signatures enables accounts and smart contracts on NEAR to sign transactions for different chains. At launch, this will include Bitcoin, Ethereum and Cosmos network chains, as well as DogeCoin and XRP Ledger. It will soon support Solana, TON Network and Polkadot, according to the team. By enabling Chain signatures, DeFi protocols can utilize assets from other chains without requiring a cross-chain bridge. This is possible because Chain Signatures are designed to be account-based rather than bridge-based.

This is particularly innovative for non-smart-contract chains like Bitcoin, DogeCoin and Ripple because none of the major bridges support these chains today,” Cole said. NEAR protocol documents show that Chain Signatures link NEAR account addresses to other blockchains using an Additive Key Derivation. This mechanism enables the
