const typedAccount = await smartAccount.useNetwork<"base">("https://mainnet.base.org" as "base");

// For custom RPC URLs without type hints (only sendTransaction, transfer and waitForTransactionReceipt methods available):
const customAccount = await smartAccount.useNetwork("https://mainnet.base.org");
