Is there a way to wait for the termination of the created transaction?

Hello!

So, for example, I sent a message with
tx, _, err := w.SendWaitTransaction(ctx, msg)

Is there a way to wait for finalization of this transaction?

Hi, transactions in TON are asynchronous, it means that each address spawns its own transaction that goes into queue. SendWaitTransaction waits for transaction completion on the wallet contract side, usually wallet spawns new transaction on the target address's side (at receiver's wallet or contract).

So it is like transactions chain, in theory it can be no final point (in case of recursive calls, unless we have enough coins). But for most of the cases you can follow this transactions chain and wait for the completion of every transaction spawned by out messages of previous transaction, and repeat it till no more new out messages emitted.

Library methods FindLastTransactionByOutMsgHash and FindLastTransactionByInMsgHash can help with it.
Later I will try to add this directly to lib.
