Missing Jetton Transfers in Transaction Query

[keyliaran]

I'm attempting to retrieve transactions, but I am only receiving a single transaction involving TON transfer. Is it possible to also retrieve transactions with Jetton (USDT) transfers?

Explorer Link:
TONSCAN Explorer

There should be two USDT transfers and one TON transfer visible for the address.

Code Sample:

package main

import (
	"context"
	"encoding/base64"
	"log"

	"github.com/xssnick/tonutils-go/address"
	"github.com/xssnick/tonutils-go/liteclient"
	"github.com/xssnick/tonutils-go/ton"
)

const (
	num = 10
)

func main() {
	client := liteclient.NewConnectionPool()
	err := client.AddConnectionsFromConfigUrl(context.Background(), "https://ton.org/global.config.json")
	if err != nil {
		panic(err)
	}

	api := ton.NewAPIClient(client, ton.ProofCheckPolicyFast).WithRetry()

	accountAddr := address.MustParseAddr("UQC7CECsMMrNJVcxJH8TlR-tK8yTS3gOC2JVvQdYyeC1RVZA")

	// we need fresh block info to run get methods
	b, err := api.CurrentMasterchainInfo(context.Background())
	if err != nil {
		log.Fatal(err)
	}

	// we use WaitForBlock to make sure block is ready,
	// it is optional but escapes us from liteserver block not ready errors
	res, err := api.WaitForBlock(b.SeqNo).GetAccount(context.Background(), b, accountAddr)
	if err != nil {
		log.Fatal(err)
	}

	lastTransactionId := res.LastTxHash
	lastTransactionLT := res.LastTxLT

	headSeen := false

	for {
		trxs, err := api.ListTransactions(context.Background(), accountAddr, num, lastTransactionLT, lastTransactionId)

		if err != nil {
			log.Fatal(err)
		}

		log.Printf("transaction count %d", len(trxs))

		for i, tx := range trxs {
			// should include only first time lastTransactionLT
			if !headSeen {
				headSeen = true
			} else if i == 0 {
				continue
			}

			if tx.IO.In == nil || tx.IO.In.Msg.SenderAddr().IsAddrNone() {
				// external message should be omitted
				continue
			}

			if tx.IO.Out != nil {
				// no outgoing messages - this is incoming Toncoins
				continue
			}

			// process trx
			log.Printf("found in transaction hash %s", base64.StdEncoding.EncodeToString(tx.Hash))
		}

		if len(trxs) == 0 || (headSeen && len(trxs) == 1) {
			break
		}

		lastTransactionId = trxs[0].Hash
		lastTransactionLT = trxs[0].LT
	}
}

Can you help me understand how to modify the code to retrieve Jetton transfer transactions alongside the TON transfer? Thanks!

Hi, as i see in explorer you have only one out transaction and you see it, if you want to see incoming then remove tx.IO.Out != nil

Currently, I have 8 transactions in total: 6 involving TON (5 incoming, 1 outgoing).

When I call the following method:

trxs, err := api.ListTransactions(context.Background(), accountAddr, num, lastTransactionLT, lastTransactionId)

And log the number of transactions (output will be 6)
log.Printf("transaction count %d", len(trxs))

I also print the transaction hashes (5 in msgs where i have recieved ton, and 1 out msg):

for i, tx := range trxs {
    log.Printf("found transaction hash %s", base64.StdEncoding.EncodeToString(tx.Hash))
}

However, I'm not receiving two transactions where I received USDT. The hashes for these missing transactions are:
(5c508c90aa472e06fa063b9d0396fec1975e1f5760d982363b3035f5bf0f7122, eDdYeBMSmHRDDeYyRzlhmUAFg/MqlbAOOiGT4W+PRdA=)

These transactions don't appear in the response, and I'm unsure why they're missing. Any ideas on what might be causing this?
