using StarkSharp;

var client = new StarknetClient("https://starknet-mainnet.public.blastapi.io");
var account = "0x1234567890abcdef...";

var balance = await client.GetBalance(account);

{
    ContractAddress = "0x...",

    Calldata = new[] { recipient, amount }
};

var result = await client.SendTransaction(transaction);
Console.WriteLine($"Transaction Hash: {result.TransactionHash}");

Contract Interaction

var contract = new Contract(contractAddress, abi, client);

// Call contract function
var result = await contract.Call("get_balance", new[] { userAddress });

// Change contract state
await contract.Invoke("set_balance", new[] { userAddress, newBalance });
