Cast

Issue

At the moment, we don't differentiate real Mainnet/Sepolia from those created by Devnet, since chain_id is the same. Thus, after commiting a transaction, Cast displays invalid links to block explorer pages.

Additional logic to block explorer printer should be added to supress it from providing links to transactions made on Devnet. Potential directions:

• Analyze URL (works on localhost, but not e.g. in Docker)
• Ask Devnet developers for advice
