Decode an off-chain SIGNATURE REQUEST before you sign it: EIP-712 typed data (eth_signTypedData_v4) or a plain personal_sign string. Turns the opaque request into a human-readable summary plus security risk flags for the drainer patterns wallets miss - gasless unlimited token approvals (EIP-2612 Permit, DAI permit, Uniswap Permit2) and asset-transferring marketplace orders (Seaport). Keyless, deterministic, zero network.
