Partial Reward Claims

Guide to partial reward claiming in Reward Vaults with WBERA emissions.

Partial Reward Claims

getPartialReward lets integrators claim a selected portion of accrued Reward Vault rewards instead of claiming the entire balance in one call.

Reward Vault emissions are distributed in $WBERA.

getReward vs getPartialReward

Method	Amount claimed	Remaining rewards	Common use case
getReward	Full accrued amount	0	Full claim
getPartialReward	Caller-selected amount	Non-zero	Streaming or periodic claims

A getPartialReward call settles the requested amount in $WBERA. rewardToken() reads $WBERA.

Solidity example

pragma solidity ^0.8.26;

interface IRewardVault {
    function earned(address account) external view returns (uint256);
    function getPartialReward(address account, address recipient, uint256 amount) external;
}

contract PartialClaimManager {
    IRewardVault public immutable rewardVault;

    constructor(address vault) {
        rewardVault = IRewardVault(vault);
    }

    function claimPartial(uint256 amount, address recipient) external {
        uint256 available = rewardVault.earned(msg.sender);
        require(amount <= available, "amount exceeds rewards");
        rewardVault.getPartialReward(msg.sender, recipient, amount);
    }
}

Integration guidance

• Read earned(account) before submitting a claim.
• Keep claim sizes below available rewards to avoid AmountGreaterThanReward.
• For delegated claim flows, enforce explicit operator authorization.
