Bridges
NEAR Chain Signatures.
NEAR Chain Signatures lets a smart contract derive a per- (account, path, curve) external key on Bitcoin, Ethereum, Solana, TON, Stellar, Sui, Aptos and sign transactions there without leaving the home chain. The Tenzro adapter wraps the NEAR MPC contract surface so Tenzro accounts can broadcast on all of those targets through a single derivation rule.
