Monitor multiple wallets in different networks

[andreclaro]

Description

Currently, this service connects just to one RPC node (devnet, testnet or mainnet-beta endpoint) and it's able to track multiple solana wallets (addresses) balances.

It will be nice that this service is able to track multiple wallets in different networks (devnet, testnet and mainnet-beta).

Meanwhile, I will deploy two services, one per network (mainnet and testnet) and if I have time and it is really required I can make the code change to add support to configure a custom RPC node per wallet.

Hello! Unfortunately, we currently only monitor wallets on mainnet-beta and that is why support for multiple networks is missing. If you have time to make PR that adds support for that it would be welcome!
