🏦Budgets & Smart Contracts
To run an incentive program that distributes onchain token rewards, projects deploy a smart contract that holds funds and manages payouts. This contract is fully controlled by the project — Fuul has no access to or control over it.
Budgets are only required for token rewards. Points-only programs don't need a smart contract or budget.
How it works
Deploy
Initialize your program through the Fuul webapp — this deploys a smart contract you fully own
Fund
Deposit tokens into the contract via the webapp, or send funds directly from any wallet or multisig
Distribute
When users earn rewards, Fuul generates signed claim checks (vouchers) that users redeem against your contract
Recover
Set expiration periods on claim checks to recover unclaimed rewards and reallocate them
Key properties
Non-custodial
Your project is the sole administrator of the smart contract. Fuul never has access to your funds.
One budget per program
All active payout rules draw from the same budget
Multi-chain
Deploy on any supported EVM chain (Arbitrum, Base, Optimism, HyperEVM, and more)
Direct transfers
Funds can be sent directly to the contract address from any source — no additional approval steps needed
Withdraw anytime
Funds can be withdrawn at any time through the webapp
Unclaimed reward recovery
Define expiration periods for claim checks. Expired, unclaimed rewards can be recovered and reused.
Claim on behalf
Projects can claim rewards on behalf of users — no action required from end users, improving UX
If the smart contract does not have sufficient balance, reward claims will fail. Monitor your budget and top up as needed.
Supported tokens
You can distribute rewards in any whitelisted ERC-20 token or native tokens (ETH, etc.) on supported chains.
To use your token for onchain payouts, Fuul requires a token whitelisting process. Contact [email protected] for details.
