Features

• x402-gated protected calls: unpaid requests return HTTP 402 with payment requirements before audit work runs.
• ERC-20 approval scanning with current allowance validation.
• Etherscan-compatible explorer fallback hooks for Approval logs when API keys are configured.
• NFT ApprovalForAll discovery hooks and revoke calldata.
• Revoke calldata for ERC-20 approve(spender, 0) and NFT setApprovalForAll(operator, false).
• Daydreams-style manifest/entrypoints plus compatibility alias for hyphenated clients.
• No private-key handling, no signing, no fund movement; unsigned tx targets/calldata only.

x402 Caveat

The deployment proves x402 reachability/payment-requirement behavior: unpaid protected calls return HTTP 402 with requirements. Full paid verify/settle is implemented through configurable facilitator /verify and /settle, but has not been live-tested because the expected facilitator URL/schema and exact Base USDC asset identifier need to be provided/configured.

Best-submission hardening update pushed.

New source commit: tolga-tom-nook/approval-risk-auditor-agent@f388ab2
Submission branch updated: #198

Additional improvements:

• Expanded supported chains to Ethereum, Base, Polygon, Arbitrum, Optimism, BSC, Avalanche, Fantom, and Gnosis.
• Added short agent-kit-style compatibility route: POST /entrypoints/audit/invoke.
• Existing routes remain: canonical /entrypoints/audit_approvals/invoke, Add Approval Risk Auditor submission #167-style /entrypoints/audit-approvals/invoke, and legacy /invoke.
• Added spender bytecode / known-spender risk flags for unknown EOA/contract spenders when checks are available.
• Expanded regression tests: npm test now passes 23 tests across 3 files; npm run build is clean.
• Redeployed Worker; /entrypoints now advertises aliases audit-approvals and audit, and unpaid /entrypoints/audit/invoke returns HTTP 402 with the canonical x402 resource.
