Rewards distributor

Merkle-claimable reward rounds: how a round is created, verified and claimed.

RewardsDistributor (0x123508dFCe1Bd5Dc5e25f627030F6a7C754429b1) pays out Points seasons, weekly prizes, creator grants and any future fee rebate. It is deliberately simple:

• Funded up front. createRound(token, root, total, expiresAt, label) pulls the full total of token from the caller before the root is published, so every listed allocation is backed by a balance the contract already holds.
• Merkle claims. A leaf is keccak256(abi.encodePacked(index, account, amount)); pairs are hashed sorted (OpenZeppelin MerkleProof). claim(roundId, index, account, amount, proof) transfers amount to account and marks the index claimed; anyone may submit a valid claim on a wallet's behalf.
• Expiry and sweep. After expiresAt, unclaimed balances can be swept to the treasury (sweep, owner only, and only once the round has expired). Before expiry the owner cannot touch a round's funds.

Claiming

The Points page lists your open allocations with the proof ready; one transaction per round. Integrators: fetch the round's leaf file (published with every round), build the proof, call claim. isClaimed(roundId, index) says whether a leaf was already paid.

Verifying a round

1. RoundCreated(roundId, token, root, total, expiresAt, label) on Blockscout gives the root and the funded total.
2. Recompute the root from the published leaf file and compare.
3. Sum the leaves: it must equal total.

Owner powers

The owner (protocol) can create rounds, sweep expired rounds and change the treasury address. It cannot alter a live round's root, pull funds before expiry, or block a valid claim. See Security model.
