fix: allow wallet connect on multiple chains

[berteotti]

Description

• Fixes wallet connect on multiple chains. Previously only worked on Mainnet.
• Adds a script to override the wallet connect verification code from env variables. This is needed so Wallet Connect can verify us. https://docs.walletconnect.com/cloud/verify
• Improves UX for wallet connection and Wallet Connect.

Would love to have a more detailed description about why are we generating a txt file with wallet connect key and so on.

I think it's important for us to get that context.
