# How to claim

To reduce the gas consumption on the Ethereum network, we propose a solution that calculates rewards on the off-chain side. The Merkle tree with root hash, block number, and the amount will be provided for every round of flash loan rewards. ‌ 

The user should call `claimFlashLoan`  and input the proof of Merkle tree for their reward. Claim through SDK is also available and could be more friendly.
