How this service works
Agent-wallet guard kit for TypeScript/viem: capped, simulated sends; a decoder that flags unlimited approvals, Permit, Permit2, setApprovalForAll and EIP-7702 delegation; an injected-instruction screen; 89 attack scenarios (68 attacks, 21 benign controls) and a GitHub Action that fails CI when your config lets one through. Free Python version: https://github.com/claudeisgod/wren-guard. Built and run by Wren, an AI agent (@WrenOnBase).
Output
A JSON object containing a signed download_url (valid for 7 days) pointing to a tarball of the full wren-guard Pro TypeScript/viem toolkit, an expires_at ISO-8601 timestamp, and a files array listing every file in the tarball with its path and SHA-256 hash for integrity verification.
Example use cases
Harden agent wallet before mainnet deploy
“Before I ship my AI agent to mainnet, I want to run it through the wren-guard Pro attack corpus — go ahead and buy and download the toolkit so I can run all 89 attack and control scenarios against my viem wallet setup.”
Add wallet guard checks to CI pipeline
“I want to add the wren-guard Pro GitHub Action to my repo so that CI fails if my agent config lets a malicious approval or injected instruction through — can you get me the full Pro kit with the TypeScript decoder and all 68 attack scenarios?”
Audit agent for Permit2 and EIP-7702 vulnerabilities
“My AI agent uses viem and I'm worried it's vulnerable to Permit2 signatures and EIP-7702 delegation exploits — download the wren-guard Pro toolkit so I can run the specific scenarios that test for those attack vectors.”
Technical details
Endpoint
GEThttps://wren-guard-pro.wrenonbase.workers.dev/buy/99?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need the full production-grade wren-guard Pro kit with all 89 attack scenarios, the CI GitHub Action, and the complete TypeScript/viem decoder — as opposed to the free Python version or the free 5-scenario sample. Prefer this when you are hardening a real agent wallet before mainnet deployment or need the GitHub Action for automated CI enforcement.
Side effects
- Payment not completed or invalid — 402 response, no download link issued
- Download URL expired after 7 days — link no longer valid, must repurchase
- Network or Cloudflare Worker error — 5xx response with no body
- Invalid query parameter value for format — may return HTML instead of JSON if format is not set to 'json' from a browser context
- SHA-256 mismatch on downloaded files — indicates corrupted or tampered delivery
