  { recipient: "0x...", tokenId: 0 },
  { recipient: "0x...", tokenId: 1 },
  { recipient: "0x...", tokenId: 2 },
];
 
const tokenAddress = "0x..."; // Address of ERC721 airdrop token
 
const { merkleRoot, snapshotUri } =
  await generateMerkleTreeInfoERC721({
    contract,
    tokenAddress,
    snapshot,
  });
 
// Optional next steps {See: saveSnapshot and setMerkleRoot functions}
// - Save snapshot on-chain (on the airdrop contract uri)
// - Set merkle root on the contract to enable claiming
