I have minted some NFTs on opensea. These are on Polygon Mumbai network. Now I want to transfer these to token to other addresses using alchemy web3. Here is the code I am using.
Note: This is supposed to run in nodejs restful API, so there is no wallet available that why I am manually signing the transaction.
async function main() {
require('dotenv').config();
const { API_URL,API_URL_TEST, PRIVATE_KEY } = process.env;
const { createAlchemyWeb3 } = require("@alch/alchemy-web3");
const web3 = createAlchemyWeb3(API_URL_TEST);
const myAddress = '*************************'
const nonce = await web3.eth.getTransactionCount(myAddress, 'latest');
const transaction = { //I believe transaction object is not correct, and I dont know what to put here
'asset': {
'tokenId': '******************************',//NFT token id in opensea
},
'gas': 53000,
'to': '***********************', //metamask address of the user which I want to send the NFT
'quantity': 1,
'nonce': nonce,
}
const signedTx = await web3.eth.accounts.signTransaction(transaction, PRIVATE_KEY);
web3.eth.sendSignedTransaction(signedTx.rawTransaction, function(error, hash) {
if (!error) {
console.log("🎉 The hash of your transaction is: ", hash, "\n Check Alchemy's Mempool to view the status of your transaction!");
} else {
console.log("❗Something went wrong while submitting your transaction:", error)
}
});
}
main();
Assumed that you have Metamask installed in your browser, and that the NFT smart contract follows ERC721 Standard
const { API_URL,API_URL_TEST, PRIVATE_KEY } = process.env;
const { createAlchemyWeb3 } = require("@alch/alchemy-web3");
const {abi} = YOUR_CONTRACT_ABI
const contract_address = CONTRACT ADDRESS
require('dotenv').config();
async function main() {
const web3 = createAlchemyWeb3(API_URL_TEST);
web3.eth.getAccounts().then(accounts => {
const account = account[0]
const nameContract = web3.eth.Contract(abi, contract_address);
nameContract.methods.transfer(account, ADDRESS_OF_WALLET_YOU_WANT_TO_SEND_TO, TOKEN_ID).send();
})
.catch(e => console.log(e));
}
main();
