How to get valid transaction_hash?
Because after using ICPledger.transfer, the return value is only BlockIndex, without transaction_hash, and at the same time, query_blocks cannot be used to query without transaction_hash.
Because it is found in ICP Explorer https://dashboard.internetcomputer.org/transactions, only transaction_hash can be viewed.
In this way, the transaction can only be browsed by obtaining the transaction_hash in advance. How to obtain the transaction_hash?
Or is it possible to view transactions by BlockIndex?
Thanks!
