I want to ask a question about how to get all the transaction records of a contract. I found an rpc provider.
https://docs.tonconsole.com/tonapi/api-v2
There is a method called
/v2/blockchain/accounts/{account_id}/transactions
Partial transaction records can be obtained
I don’t know much about the acquisition and principle of after_lt and before_lt. I randomly extracted two values ​​from the transaction record of a certain contract in the blockchain browser. When I requested it here, I found that the obtained result data was insufficient.
