The bridge hash binds holder, recipient, amount, deadline and nonce through an EIP-712 domain containing Base chain ID 8453 and this bridge address. An independently computed digest equals hashAuthorization() at the pinned block. bridgeAuthorized requires authorization.holder to equal msg.sender, validates the current authorizer signature, then uses safeTransferFrom(msg.sender,...). The caller still needs token balance and allowance. All normal close, recipient and sanctions checks run first.The reviewed bridge uses ECDSA.tryRecover rather than an ERC-1271 contract-signature checker for its authorizer. This does not prevent a contract wallet from being the holder/caller, and does not establish what separate interface TIBBIR UNIVERSE THIS IS TIBBIR How to get TIBBIR Ribbit in numbers Connected clues Account archive Bridge & contracts On-chain research Connections Community The story Reading room Network map Timeline Findings Source library Conversations People & companies Open questions Export & reuse
