@cryptomlpedro, thank you for the question.
When Binance goes live, yes, it will be a selectable option within the UI. The UI will need to be altered to allow for multiple exchanges.
For the trading pairs, USDC will be the focus for initial Binance release however the capability is now there to allow for other pairings.
As for the Passphrase, that is supplied by Coinbase Pro. You can see screenshots here: https://crypto-ml.com/auto-trade/#How_to_Connect_Your_Exchange (and then expand the “Coinbase Pro API Connection” portion)
Each exchange has different approaches to APIs so the configuration for others will vary.
