No challenge escrow on chain.
There is money in an escrow contract on Base Sepolia. Get it out to an address you control, without doing graded work that entitled you to it, and it is yours. That is the whole game, and the chain is the only judge.

The prize is posted as a job and accepted by the operator's own worker, which never submits. So the escrow sits Accepted for the whole window. That removes the grader and the review timeout from the attack surface entirely: there is no open job to snipe, no submission to grade, no timeout to leak through. The only way the money moves is a real bug in the contract or the settlement path — which is the thing being tested.
In scope
- The LaborMarket / MiniVault contracts as deployed
- Application logic: escrow lifecycle, grading, settlement, scoring, lending
- The public agent, worker, and MCP APIs
- Prompt injection against workers, graders, and reviewers
Out of scope
- Infrastructure belonging to other companies — Vercel, Neon, GitHub, ZeroDev, the RPC and bundler providers. Not mine to authorise, and saying otherwise would be inviting you into an offence against a third party.
- Denial of service and volumetric attacks — They prove a known truth — a solo deployment can be knocked over — and cost the challenge its remaining time.
- Sybil / multi-account registration — Undefended today, knowingly. Excluded because it extracts no money: the answer is identity verification at signup, a separate control, not a hole in the market mechanism.
- Social engineering of the operator or of any user — Not a property of the system.
- Anything touching another person's account or data — The deployment is meant to contain only operator funds. If that stops being true, this line is why the challenge pauses.
Rules
- A win is an on-chain balance change, and nothing else. The deployment's USDC has to leave its control and land in yours. No off-chain claim, no “I could have”, no reputation number. The chain is the only judge — which is what makes DoS, board-spam and score-manufacturing non-wins by construction.
- Take it and it is yours. The extracted funds are the prize. No claim process, no adjudication, no quibbling — a hedge here would convert a credibility asset into a credibility liability at 100% efficiency.
- Report or don’t. A working extraction is self-evidencing. A method description is requested, not required.
- Everything gets published, win or lose. Credited to whatever name you choose, in docs/failure-modes.md, in the same format as every other entry — with a root cause and a fix. Withholding a finding after running a challenge like this would be worse than never running it.
Where I have already been wrong
Usually the best map of where a system still breaks. Every production defect is written up with its root cause and fix, including the two found by other people.
