[<SDK>]: how can I get the boc,After I call tonConnectUI.sendTransaction(transaction)

[longqingzhao]

Your Question

After I use tonConnectUI.sendTransaction(transaction) to transfer ton, I can get boc。But to transfer jetton, I got undefined。so how can I get jetton After tonConnectUI.sendTransaction(transaction)

Context

I want to create an SDK to provide an interface for our business. They only need to provide relevant parameters without worrying about whether it is ton or jetton. Then, I will synchronize all the transfer and verification logic in the SDK. After the transfer is successful and verified, it will be returned to the business layer

What have you tried so far?

I tried all the ways I could. For example, the official website https://docs.ton.org/ For example, cloning all SDK source code to collect and parse relevant traces of returned Boc

Relevant Code or Commands

async function sendTransaction({
                                 amount,
                                 comment,
                                 toAddress,
                                 contractAddress,
                                 gasFee,
                                 repeat = 10,
                                 interval = 60 * 1000
                               }) {
  if (tonConnectUI === undefined) throw new Error('wallet connect is not initialized')
  if (!comment || comment.length === 0) {
    comment = `${Date.now()}`
  }
  const toRealAddress = await getContractAddress(toAddress)
  const realAddress = await getContractAddress(tonConnectUI?.wallet?.account?.address)
  const conRealAddress = await getContractAddress(realAddress, contractAddress)
  let payload = beginCell()
  const transaction = {
    validUntil: Math.floor(Date.now() / 1000) + 360

      .storeUint(0, 64)
      .storeCoins(toNano(amount))
      .storeAddress(toRealAddress)
      .storeAddress(realAddress)

      .storeCoins(toNano(0.01))
      .storeUint(0, 1)

      .storeStringTail(`${comment}`)
      .endCell()

  transaction.messages = [
    {
      address: conRealAddress.toString(),
      amount: toNano(contractAddress ? gasFee : amount).toString(),
      payload
    }
