 You can configure custom RPC endpoints in your .env file for better reliability and higher rate limits. If not specified, the tool will fall back to public RPC endpoints.
 
 ### Network Selection
-For EVM operations, you can specify the network by name (ethereum, base, arbitrum, optimism, bsc, polygon, avalanche). The tool will automatically use the appropriate RPC endpoint and network configuration.

 ### THORChain Configuration
 The tool uses Nine Realms public endpoints by default, but you can configure a custom THORChain node URL in the .env file for better reliability and rate limits.
