// 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();
// Fetch NFT balance using Tatum SDK. import { TatumSDK, Network } from '@tatumio/tatum'; const tatum = await TatumSDK.init({ network: Network.ETHEREUM }); const balance = await tatum.nft.getBalance({addresses: [‘your address’]});
