Decode EVM transaction calldata before signing: finds the function signature (signature DB, verified by re-encoding to reject selector collisions), decodes all arguments, expands multicall batches, and warns about unlimited token approvals, approve-all-NFTs, permits, ownership changes and upgrades. Works for any EVM chain.
