How to subscribe transaction on account #19488

Closed stone89son closed 2 years ago

stone89son commented 3 years ago

Problem

I am building a trading platform. When a user orders a Buy token, they will have to send SOL to my SOL account. The part I'm building is getting real time that transaction and adding it to the database, where in Solana Blockchain I must is research? Thank for read and help me.

hi, the best is I think to subscribe off-chain using 

         connection!.onLogs(PUBKEY_OF_YOUR_ACCOUNT,
         ( logs, context ) => getlogssubscribe( logs,context ),
         'finalized',
         );

then in getlogssubscribe you call an on-chain program and send the tx signature you just get. in that on-chain program you can use https://docs.rs/solana-client/latest/solana_client/rpc_client/struct.RpcClient.html#method.get_transaction to get infrormation about the tx. if is it ok, write in your database
