Airdrop Utils

Airdrop utils module contains the verify function to check if a Merkle proof combined with an address and amount are part of the Merkle tree root.


Checks if the sender is allowed to redeem an amount from an airdrop using Merkle proofs. It returns the index of his Merkle proof to add to the Bitmap struct.

public fun verify(
    root: vector<u8>,
    proof: vector<vector<u8>>, 
    amount: u64, 
    sender: address
): u256
  • @param root: The Merkle tree root that keeps track of all the airdrops.
