Hello, I have a SC for distributing funds and i can't get my head around nonce. I have a local wallet which will make a lot of contract function calls and each call will make a transaction in the SC to send funds to different wallets. How should i choose the nonce? I guess that on the local wallet i have to increment the nonce i get from the API for the contract calls, but for the SC transaction inside the function how should i manage the nonce?
