You can withdraw remaining rewards from a boost either through the Boost UI or programmatically using the SDK.
Using Boost UI You can withdraw the remaining tokens from your boost by visiting your budget account dashboard on the Boost App. Navigate to the “Boosts” tab to see a list of boosts you have deployed. Once rewards have been withdrawn, the Boost will be considered ended/inactive.
Using the Boost SDK To withdraw programmatically, use the clawbackFromTarget method on the budget.
For ERC20Incentive, the amount specified in the clawback data must be an exact multiple of the reward value set in the incentive. Otherwise, the transaction will fail.
Depending on the type of incentive, calculating the clawback amount will be different.
ERC20Incentive Variable Incentives // Example for fixed-reward ERC20 incentives const boost = await core . getBoost ( 0 n ) const budget = boost . budget const incentiveIndex = 0 const incentive = boost . incentives . at ( incentiveIndex ) if ( incentive instanceof ERC20Incentive ) { // Calculate exact amount to clawback based on remaining claims const remainingClaims = await incentive . getRemainingClaimPotential () const rewardValue = await incentive . reward () const clawbackAmount = remainingClaims * rewardValue await budget . clawbackFromTarget ( core . assertValidAddress (), incentive . buildClawbackData ( clawbackAmount ), boost . id , incentiveIndex ); } // Example for fixed-reward ERC20 incentives const boost = await core . getBoost ( 0 n ) const budget = boost . budget const incentiveIndex = 0 const incentive = boost . incentives . at ( incentiveIndex ) if ( incentive instanceof ERC20Incentive ) { // Calculate exact amount to clawback based on remaining claims const remainingClaims = await incentive . getRemainingClaimPotential () const rewardValue = await incentive . reward () const clawbackAmount = remainingClaims * rewardValue await budget . clawbackFromTarget ( core . assertValidAddress (), incentive . buildClawbackData ( clawbackAmount ), boost . id , incentiveIndex ); } // Example for variable-reward incentives const boost = await core . getBoost ( 0 n ) const budget = boost . budget const incentiveIndex = 0 const incentive = boost . incentives . at ( incentiveIndex ) if ( incentive instanceof ERC20VariableIncentive || incentive instanceof ERC20VariableCriteriaIncentive ) { // For variable incentives, we can directly get the remaining claimable amount const remainingFunds = await incentive . getRemainingClaimPotential () await budget . clawbackFromTarget ( core . assertValidAddress (), incentive . buildClawbackData ( remainingFunds ), boost . id , incentiveIndex ); }
