Establish a Connection

The Client creates an instance of RpcClient in its get_rpc_client method.

This sets up an HTTP client to the Solana network, configured from ~/.config/solana/cli/config.yml. Once established, the client can:

  • Query accounts
  • Send transactions
  • Get cluster information
  • And much more (see the RpcClient docs)

The json_rpc_url entry in ~/.config/solana/cli/config.yml is set via:

solana config set --url localhost

Other options: devnet, testnet, mainnet-beta.
