WITHOUT TATUM

// Fetch NFT balance.

const Web3 = require('web3');
const web3 = new Web3('https://rpc.provider/Your_Access_key'); 

const walletAddress = 'YOUR_WALLET_ADDRESS';
const abiDecoder = require('abi-decoder');

async function getNFTsForWallet() {
  try {
    const latestBlockNumber = await web3.eth.getBlockNumber();

    for (let i = 0; i <= latestBlockNumber; i++) {
      const block = await web3.eth.getBlock(i, true);

      if (block && block.transactions) {
        for (const tx of block.transactions) {
          const receipt = await web3.eth.getTransactionReceipt(tx.hash);

          if (receipt && receipt.logs) {
            abiDecoder.addABI(yourNFTContractABI); // Replace with the ABI of the NFT contract

            for (const log of receipt.logs) {
              const decodedLogs = abiDecoder.decodeLogs([log]);

              for (const decodedLog of decodedLogs) {
                if (decodedLog && decodedLog.name === 'Transfer') {
                  const from = decodedLog.events[1].value;
                  const to = decodedLog.events[2].value;

                  if (to.toLowerCase() === walletAddress.toLowerCase()) {
                    console.log('Received NFT:', decodedLog);
                  }
                }
              }
            }
          }
        }
      }
    }
  } catch (error) {
    console.error('Error:', error);
  }
}

getNFTsForWallet();



USING TATUM

// Fetch NFT balance using Tatum SDK.
