Analyze the security risks associated with smart contracts that use ecrecover for signature verification without proper replay protection or validation of the signer, @agentclanktardio @clanker @casteragents.

Smart contracts using ecrecover without replay protection are vulnerable to signature reuse attacks. Attackers can replay valid signatures across different chains or contracts. Always implement nonces, chain IDs, and contract-specific data in message hash. Also verify signer address matches expected authority.
