Thirdweb .NET SDK

Overview

The Thirdweb .NET SDK is a powerful library that allows developers to interact with the blockchain using the .NET framework. It provides a set of convenient methods and classes to simplify the integration of Web3 functionality into your .NET applications.

Features

• Connect to any EVM network
• Query blockchain data using Thirdweb RPC
• Interact with smart contracts

Installation

To use the Thirdweb .NET SDK in your project, you can either download the source code and build it manually, or install it via NuGet package manager.

dotnet add package Thirdweb

Usage

using Thirdweb;

// Create a client
var client = new ThirdwebClient(secretKey: secretKey);

// Interact with a contract
var contract = new ThirdwebContract(client: client, address: "0xBC4CA0EdA7647A8aB7C2061c2E118A18a936f13D", chain: 1, abi: "function name() view returns (string)");
var readResult = await ThirdwebContract.ReadContract<string>(contract, "name");
Console.WriteLine($"Contract read result: {readResult}");

// Or directly interact with the RPC
var rpc = ThirdwebRPC.GetRpcInstance(client, 1);
var blockNumber = await rpc.SendRequestAsync<string>("eth_blockNumber");
Console.WriteLine($"Block number: {blockNumber}");

// Create accounts
var privateKeyAccount = new PrivateKeyAccount(client, privateKey);
var embeddedAccount = new EmbeddedAccount(client, "myawesomeemail@gmail.com");
var smartAccount = new SmartAccount(client, embeddedAccount, "0xbf1C9aA4B1A085f7DA890a44E82B0A1289A40052", true, 421614);

// Attempt to connect pk accounts
await privateKeyAccount.Connect();
await embeddedAccount.Connect();

// Relog if embedded account not logged in
if (!await embeddedAccount.IsConnected())
{
    await embeddedAccount.SendOTP();
    Console.WriteLine("Please submit the OTP.");
    var otp = Console.ReadLine();
    (var embeddedAccountAddress, var canRetry) = await embeddedAccount.SubmitOTP(otp);
    if (embeddedAccountAddress == null && canRetry)
    {
        Console.WriteLine("Please submit the OTP again.");
        otp = Console.ReadLine();
        (embeddedAccountAddress, _) = await embeddedAccount.SubmitOTP(otp);
    }
    if (embeddedAccountAddress == null)
    {
        Console.WriteLine("OTP login failed. Please try again.");
        return;
    }
}

// Connect the smart account with embedded signer and grant a session key to pk account
await smartAccount.Connect();
_ = await smartAccount.CreateSessionKey(
    signerAddress: await privateKeyAccount.GetAddress(),
    approvedTargets: new List<string>() { Constants.ADDRESS_ZERO },
    nativeTokenLimitPerTransactionInWei: "0",
    permissionStartTimestamp: "0",
    permissionEndTimestamp: (Utils.GetUnixTimeStampNow() + 86400).ToString(),
    reqValidityStartTimestamp: "0",
    reqValidityEndTimestamp: Utils.GetUnixTimeStampIn10Years().ToString()
);

// Reconnect to same smart account with pk account as signer
smartAccount = new SmartAccount(client, privateKeyAccount, "0xbf1C9aA4B1A085f7DA890a44E82B0A1289A40052", true, 421614, await smartAccount.GetAddress());
await smartAccount.Connect();

// Log addresses
Console.WriteLine($"PrivateKey Account: {await privateKeyAccount.GetAddress()}");
Console.WriteLine($"Embedded Account: {await embeddedAccount.GetAddress()}");
Console.WriteLine($"Smart Account: {await smartAccount.GetAddress()}");

// Initialize wallet
var thirdwebWallet = new ThirdwebWallet();
await thirdwebWallet.Initialize(new List<IThirdwebAccount> { privateKeyAccount, embeddedAccount, smartAccount });
thirdwebWallet.SetActive(await smartAccount.GetAddress());
Console.WriteLine($"Active account: {await thirdwebWallet.GetAddress()}");

// Sign, triggering deploy as needed and 1271 verification
var message = "Hello, Thirdweb!";
var signature = await thirdwebWallet.PersonalSign(message);
Console.WriteLine($"Signed message: {signature}");
