How this service works
A buyer-side control console for signature risk, EIP-712 review, transaction decoding, ERC20 allowance risk, Permit/Permit2 approvals, transaction simulation summaries, spend guard policy, receipt gate enforcement, and private-key boundaries.
Output
A JSON object containing: a 'controls' array of active wallet safety controls, a 'boundaries' object defining private-key and signing boundaries, a 'copyPastePolicy' string describing clipboard/copy-paste rules, a 'privateKeysAccepted' boolean, and metadata fields (tool name, route, project, deterministic flag). Summarizes all relevant spend guard, EIP-712, ERC20 allowance, Permit/Permit2, transaction simulation, and receipt gate policies for the given app and chain.
Example use cases
Autonomous agent spend guard setup
“Set up the wallet signing safety pack for my autonomous trading agent called 'trade-bot' on Base (chain 8453) with a max of $0.10 per call — I need to know the spend guard policy, ERC20 allowance risk flags, and whether private keys are accepted.”
EIP-712 signature risk review before deployment
“Before I deploy my DeFi agent app 'defi-agent' on Ethereum mainnet (chain ID 1), can you pull the wallet signing safety pack with a $0.05 max per call and show me the EIP-712 review controls and Permit2 approval rules?”
Receipt gate enforcement for x402 payment agent
“My x402 payment agent app 'pay-runner' is running on Base (chain 8453) with a $0.02 max per call — fetch the wallet safety pack and tell me what receipt gate enforcement and copy-paste policy rules are in effect.”
Technical details
Endpoint
GEThttps://x402-wallet.558686.xyz/v1/tools/wallet-signing-safety-packWhen to prefer
Choose this endpoint when an AI agent needs a consolidated, structured wallet safety policy pack before executing on-chain transactions — particularly when you need EIP-712 risk assessment, ERC20 allowance review, Permit2 approval rules, spend guard limits, and private-key boundary enforcement all in one call. Prefer it over building individual checks piecemeal when operating on EVM chains with an autonomous agent wallet.
Side effects
- Missing or invalid chainId returns an error or empty controls
- Unknown appName may return default/empty policy set
- maxPerCallUsd of zero or negative may cause validation rejection
- Network or payment failure (x402 $0.018 USDC required per call) returns 402 Payment Required
- Unsupported chainId may return empty boundaries object
