hi

const seqno = await wallet.methods.seqno().call();

This code cannot get seqno and the return value is null. Is there any possible error that could cause this?

If wallet is uninitialized, it will return null. You should do ?? 0 then.

const TonWeb = require('tonweb');

const tonweb = new TonWeb(new TonWeb.HttpProvider('https://toncenter.com/api/v2/jsonRPC', {apiKey: '3b617d26c48aebc729cf5c4601f4732c0cf14331674ad4762e419180704d1330'}));

const wallet = tonweb.wallet.create({address: 'EQAI9IoJmk--P5U9i4wa3UpI0juy-zcF-vJclvWS5NUa58Vh'});

async function sendTransfer() {


console.log(tonweb)
const seqno = await wallet.methods.seqno().call();

console.log(seqno);
}

sendTransfer();

Are you familiar with ?? JS operator?

Do I need to call a method on tonweb to activate this address?

Outgoing transfer will do that.

I have already transferred money to this address

Yes, and money is there. How the contract would become init when money is transferred?

You must obtain seqno before transferring money, but when I call the tonweb SDK method to obtain seqno, it is null. I don’t understand whether there is a problem with my code or what other operations need to be done.

When seqno is null, it shall be replaced with zero.

ok i try again

thanks

Review your implementation carefully, making sure to follow these steps. It's crucial to obtain the sequence number (seqno) before proceeding:
Note that you most get the seqno first
1. const seqno = await WalletContract.getSeqno(); //Outside your whileloop if are useing try() it should be outside the try()
2. let currentSeqno = seqno; //outside the whileloop
3. while (currentSeqno == seqno) { //set your while condition like so
console.log("waiting for transaction to confirm...");
await sleep(1500);
currentSeqno = await walletContract.getSeqno();
}
console.log("transaction confirmed!");
}
