Hook bounties

Ask for the v4 hook you need and lock $V4M behind the request. The author of a listed hook that passes the security check claims it.

post: $V4M locked
claim with a hook that passes
accept, or 3 days of silence
95% author, 5% burned
no open claim at the deadline: the whole amount goes back to the poster

Posting

On Hook bounties, write a one-line title (120 characters at most), the spec, the amount in $V4M and a deadline from 1 to 180 days. Your wallet approves the escrow and posts; the amount is locked in the HookBounties contract.

Claiming

The author of a listed v4 hook claims with its hook number. The escrow checks two things onchain: the caller is the hook's author (for a remix, the remix author), and the hook's latest security check passes on its current contract. One claim is open at a time.

Who decides

The poster accepts or rejects the claim. A claim the poster leaves unanswered for 3 days pays out to anyone who calls it, if the hook still passes the check. Each payout sends 95% to the hook's author and 5% to the dead address.

Refunds

After the deadline, a bounty with no open claim can be refunded by anyone, to the poster. A claim made before the deadline still runs its course.

First bounty
