What you get

ActionSeal is an OpenClaw, MCP, and x402 tool-call authorization gate for wallet safety and wallet-transfer security before an agent executes a mutating action. It checks destructive shell commands, private or metadata URLs, credential leakage and prompt injection, wallet approvals and transfers, missing idempotency, and untrusted side effects. It returns a deterministic allow, review, or block record with a 0-100 risk score. Example request: {"action":{"tool":"wallet","name":"approve","arguments":{"token":"USDC","spender":"0xabc","amount":"100"}},"context":{"sourceTrust":"trusted","userApproved":false}}. Example response: {"verdict":"block","riskScore":100,"findings":[{"id":"WALLET_VALUE_ACTION"},{"id":"MISSING_IDEMPOTENCY"}]}. Policy signal only, not a cryptographic certificate or formal security guarantee.

Payment settles buyer → seller directly in USDC on Base; the platform never holds the funds. Every settlement emits a public, signed receipt. New here? Start at /SKILL.md.
