RPCh SDK integration B2B use case

RPCh SDK integration

Liquality offers a lot of providers for a lot of different chains. Instead of integrating RPCh on a per provider settings, integrate it globally and enable it then for all EVM based chains and p providers.

Development work:

• Instantiate RPCh SDK with a static client secret as thiis will be the same for all wallet users
• Integrate RPCh SDK into EVM based providers, so that when RPC requests happen they are send with the SDK instead
• RPC endpoints can be configured the usual way in liquality and are adhered to by RPCh (use them during SDK init or send API call)

• Real last work on the wallet by their developers was done in April 2023.
• The readme build and run commands do not work, there is an issue from Dec 2022 asking for a fix, and it wasn't tackled. https://github.com/liquality/wallet/issues/965
• Wallet uses Node 16, when we need at least Node 18
• Seems that wallet future is dead
