Account Abstraction

Deploys a smart account for the user to interact with your app. The specified personal wallet will be the admin signer. For more information about Account Abstration, see the glossary.

using Thirdweb;
 
public async void ConnectWallet()
{
    // Reference to your Thirdweb SDK
    var sdk = ThirdwebManager.Instance.SDK;
 
    // Configure the connection
    var connection = new WalletConnection(
      provider: WalletProvider.SmartWallet,        // The wallet provider you want to connect to (Required)
      chainId: 1,                                  // The chain you want to connect to (Required)
      password: "myEpicPassword",                  // If using a local wallet as personal wallet (Optional)
      email: "email@email.com",                    // If using a personal wallet login option that requires email (Optional)
      personalWallet: WalletProvider.LocalWallet   // The personal wallet you want to use with your Smart Wallet (Optional)
    );
 
    // Connect the wallet
    string address = await sdk.wallet.Connect(connection);
}

The ultimate goal of a smart account is to be able to sponsor gas fees for your users, while providing a signless and gasless experience.

They also work with any wallet provider as the EOA, but it is recommended to use a signless wallet, like Embedded Wallets, for the best experience.

You would then be able to login to the exact same persistent EOA and smart account address across your apps, and even across different platforms.

You can also create session keys (revokable), allowing new signers to interact with the smart account without being the admin. You may also add/remove admins.

using Thirdweb;
 
// Reference to your Thirdweb SDK
var sdk = ThirdwebManager.Instance.SDK;
 
// Create a session key
string signerAddress = "0xSignerAddress";
List<string> approvedTargets = new List<string> { "0xTargetAddress" };
string nativeTokenLimitPerTransactionInWei = "0";
string permissionStartTimestamp = "0";
string permissionEndTimestamp = Utils.GetUnixTimestampIn10Years().ToString();
string reqValidityStartTimestamp = "0";
string reqValidityEndTimestamp = Utils.GetUnixTimestampIn10Years().ToString();
 
var createSessionResult = await sdk.wallet.CreateSessionKey(
  "0xSignerAddress",
  approvedTargets,
  nativeTokenLimitPerTransactionInWei,
  permissionStartTimestamp,
  permissionEndTimestamp,
  reqValidityStartTimestamp,
  reqValidityEndTimestamp
);
 
// Get a list of current signers with permission details
List<SignerWithPermissions> signers = await sdk.wallet.GetAllActiveSigners();
 
// Revoke a session key
var revokeSessionResult = await sdk.wallet.RevokeSessionKey("0xSignerAddress");
 
// Add admin
var addAdminResult = await sdk.wallet.AddAdmin("0xSignerAddress");
 
// Remove admin
var removeAdminResult = await sdk.wallet.RemoveAdmin("0xSignerAddress");
 
// These features pair well with the `smartWalletAccountOverride` option to connect to a specific smart wallet
var connection = new WalletConnection(
  ...options,
  smartWalletAccountOverride: "0xSmartWalletAddress"
);
var address = await sdk.wallet.Connect(connection);

Smart accounts, through paymasters, can be seen as a "plugin" to your user wallets, whereby all gas fees can be sponsored onchain. To enable this, simply set the gasless option to true in your ThirdwebManager prefab.

All smart accounts are deployed through an Account Factory, which is a contract that deploys smart accounts on behalf of your users. You would need to set this address in your ThirdwebManager prefab's settings as well.
