On-chain escrow · OPN Testnet

Rewards stay locked
until the proof
is real.

RewardVault holds giveaways, ambassador rewards, bounties, and campaign payouts in escrow on OPN Chain. Every wallet gets a Merkle proof. Tokens move when the proof, the amount, and the deadline agree.

3 wallets · one leaf each

A CSV becomes one leaf per wallet. Duplicate addresses are added together, and invalid amounts are rejected.

Workspace

Campaigns, claims, and locked balances in one view.

Connect a wallet, switch to OPN Testnet, and run the drop from the same screen you are about to open.

01

One leaf per wallet

Each leaf is a hash of the address and its allocation. A messy CSV is cleaned before the root is published.

leaf = keccak256(address, allocation)
0xA91c…  2,400
0x18Fd…    800
0x77B1…  5,000

02

Claim any installment

Recipients take part of an allocation now and the rest later. The original proof keeps working until the allocation is used up.

03

Each drop is sealed

A campaign keeps its own root, deadline, funding, and claim total. Publishing the root is the last edit it ever gets.

Vault rules

The owner sets the drop. The contract keeps the books.

  1. 01

    Cancel only while the drop is untouched

    The owner can cancel before the deadline, and only if nobody has claimed yet.

  2. 02

    Unclaimed tokens return after the deadline

    Once the deadline passes, the owner withdraws whatever the campaign never paid out.

  3. 03

    Locked rewards stay locked

    Surplus recovery can move leftover reward tokens. It leaves campaign liabilities where they are.
