A simplified version of thirdweb's AirdropERC721 contract used for migrating your NFTs to a new wallet. Works with thirdweb gasless options
Usage (Node.js)
- With gasless (very useful when you want to rescue the NFTs that are stuck in your drained wallets)
try {
const _tokenAddress = process.env.TOKEN_ADDRESS!; //
const migrateContractAddress = process.env.MIGRATE_CONTRACT!; // migrate erc721
const _recipient = process.env.NEW_WALLET!; // new wallet that will receive the rescued nfts
const thirdwebSdk = ThirdwebSDK.fromPrivateKey(process.env.LEAKED_PRIVATE_KEY!, 'polygon', {
gasless: {
openzeppelin: {
relayerUrl: process.env.OZ_GASLESS_POLYGON!,
},
},
secretKey: process.env.THIRDWEB_SECRET_KEY,
});
const _tokenOwner = process.env.DRAINED_WALLET_ADDRESS!; // leakedWalletAddress
const [migrateContract, nftContract] = await Promise.all([
thirdwebSdk.getContract(migrateContractAddress),
thirdwebSdk.getContract(_tokenAddress),
]);
// You need to approve the Migrate contract to send the NFTs on your behalf
const isApproved = await nftContract.erc721.isApproved(_tokenOwner, migrateContractAddress);
if (!isApproved) await nftContract.erc721.setApprovalForAll(migrateContractAddress, true);
else console.log('contract is approved to send nfts');
const owners = await nftContract.erc721.getAllOwners();
// Get all the tokenIds of the targeted collection in the drained wallet
const allTokenIds = owners.filter((item) => item.owner === _tokenOwner).map((item) => item.tokenId);
// Due to block space limit, we only send a few hundred per batch (tweak the number til it works for u)
const magicNumber = 100;
const _tokenIds = allTokenIds.length <= magicNumber ? allTokenIds : allTokenIds.slice(0, magicNumber);
// Start migrating
const data = await migrateContract.call('transferERC721', [_tokenAddress, _tokenOwner, _recipient, _tokenIds]);
return res.send(data);
return res.send(_tokenIds);
} catch (err) {
console.log(err);
return res.send(err);
