Poster review
The poster approves, which pays out, or rejects with a reason.
For everyday tasks: bugs, docs, designs.
Where the reward lives, and who gets to release it
The rules the bounty contract enforces, in plain words.
Escrow: the reward is locked before anyone starts
Posting moves the reward into escrow, a smart contract that pays an approved contributor or refunds you if you cancel.
- Anyone can check the locked amount first.
- The poster can't spend it elsewhere.
- Cancel only while nothing awaits a decision.
Two ways to decide
Each bounty says who decides before anyone starts.
Validator vote
A named council votes; the quorum (e.g. 2 of 3) triggers the payout.
For audits, prizes and grants.
Rejections and refunds
Every rejection has a reason
Contributors see the note and can resubmit.
One winner, and the others are told
The others are marked "not selected".
Refunds are public
Cancelling refunds the poster, in the bounty's history.
Visibility by role
Everyone can read every bounty; posters restrict who can submit.
- Open to everyone
- Monark members
- Ambassadors only
Reputation you earn, not buy
Earned only from approved work. It can't be bought or transferred.
| Difficulty | Points per approved bounty |
|---|---|
| Beginner | +10 |
| Intermediate | +25 |
| Advanced | +50 |
| Expert | +100 |
For developers and students
The demo's data layer mirrors this contract, so it can switch to wagmi/viem calls.

- Left as exercises: validator rotation, disputes, multiple winners.
- Worth studying: reentrancy on release, cancel rights, unreachable quorums.
