Hello guys, good day, how is everyone?
I am trying to write a program that can scan the pairaddress of a contract and add liq then sync in 1 transaction. I want the contract to scan the pair address and replace according to a set threshold every 3 - 5 seconds. This has to scan every 3 seconds and top up the threshold automatically.

I tried building a webapp that can do this but it only allows 15 minutes. I want to try hangfire now. Can I build a smart contract that can do this? Can anyone help if you have an idea?
