v4.20.1

What's Changed

• [Cross-Platform] Added support for new chains.

This patch also removes a duplicate DLL and incomplete third party prefabs making the import process in Unity 2021 a little easier.

v5.0.0-beta.4

What's Changed

Support for Account Abstraction 0.7.0 (EntryPoint 0.7.0)

You may now opt to use our new Account Factories that are built on top of the 0.7.0 ERC-4337 standard release, by passing Constants.ENTRYPOINT_ADDRESS_V07 as your entryPoint parameter in SmartWallet.Create or through the ThirdwebManager's ConnectWallet function. Note that we will continue supporting AA 0.6.0 - so no rush.

Among various other things, this unlocks:

• Improved gas costs when interacting with Smart Wallets due to packed UserOp structs and more changes.
• Improved gas limit estimations and faster simulation.
• Token Paymasters - though not live on 0.7 until a little later, the API has been exposed to pass a TokenPaymaster (enum) when creating a Smart Wallet and choose which ERC20 you want users to pay gas with. This is an alternative to the default gasless flow where you sponsor gas for your users.

We've also added support for Abstract Testnet's native account abstraction (ZkSync-based chain).

Authentication

The new API for authenticating with your backend through SIWE in a single call looks like this now.

public static async Task<T> Authenticate<T>(
        this IThirdwebWallet wallet,
        string domain,
        BigInteger chainId,
        string authPayloadPath = "/auth/payload",
        string authLoginPath = "/auth/login",
        string authPayloadMethod = "GET",
        string authLoginMethod = "POST",
        bool separatePayloadAndSignatureInBody = false,
        IThirdwebHttpClient httpClientOverride = null
)

We've made it a little more flexible so you can hopefully get rid of any custom authentication code you might have and use this helper instead to unlock backend thirdweb auth with any wallet easily.

We've also fixed an issue with some older variants of Smart Wallet factories which resulted in "Invalid SIgnature" being thrown upon personal signing (and by extension, authenticating).

API Improvements

• Low Level - Added IThirdwebWallet.ExecuteTransaction support for external and smart wallets to execute raw low level transaction input rather than going through ThirdwebTransaction.
• Low Level - Simplified the ThirdwebTransactionInput by adding a constructor with user friendly types.
• Mid Level - Added ThirdwebTransaction.Prepare, allowing you to have a quick way to estimate, simulate and populate a transaction without sending it.
• High Level - Deprecated Utils.FetchThirdwebChainAsync, please use Utils.GetChainMetadata as the former will be removed in a future version.

General Improvements

• Stricter coding standards were implemented, making sure the core won't fail you regardless of which .NET version or platform you're on.
• Improved performance and stability across the board.
• Various minor bugfixes were implemented and a couple properties were renamed to improve DX.

v5.0.0-beta.3

What's Changed

Unity 6.0.0 Preview, SIWE as a login method, Account Linking

• Added support for Unity 6.0.0+ Preview (Unity 2023 Tech Stream 3)
• Added SIWE (Sign In With Ethereum) as an additional login provider for In-App Wallets.

// The external wallet you want to login with
var myExternalWallet = await PrivateKeyWallet.Generate(client: Client); // for simplicity, using generated wallet

// Setup auth with SIWE
var siweOptions = new InAppWalletOptions(authprovider: AuthProvider.Siwe, siweSigner: myExternalWallet);

// Setup connect options with chain ID
var connectOptions = new WalletOptions(provider: WalletProvider.InAppWallet, chainId: 421614, inAppWalletOptions: siweOptions);

// Login with SIWE!
var siweInAppWallet = await ThirdwebManager.Instance.ConnectWallet(connectOptions);
var address = await siweInAppWallet.GetAddress();

• Added ability to link accounts, creating a Unified Identity across email, phone, social and other authentication options.

// Your main InAppWallet account, already authenticated and connected
InAppWallet mainInAppWallet = ...

// An InAppWallet with a new auth provider to be linked to the main account, not connected
InAppWallet walletToLink = await InAppWallet.Create(client: Client, authProvider: AuthProvider.Telegram);

// Link Account - Headless version
var linkedAccounts = await mainInAppWallet.LinkAccount(walletToLink: walletToLink);

// Link Account - Unity wrapper version
var linkedAccounts = await ThirdwebManager.Instance.LinkAccount(mainInAppWallet, walletToLink);

// You can also fetch linked accounts at any time
List<LinkedAccount> linkedAccounts = await mainInAppWallet.GetLinkedAccounts();

The LinkAccount API requires the parameters you typically use to login with a normal InAppWallet. It will authenticate the new wallet and link it directly to the main wallet. This makes it simple to have multiple identities tied a single evm-compatible account.

Miscellaneous

• Performance and speed improvements for OTP based login methods.
• Added caching for Utils.FetchThirdwebChainDataAsync.
• Added Utils.IsEip155Enforced to check whether a chain enforces EIP 155.
• Added smarter transaction gas fee defaults based on whether chain supports 1559.
• ThirdwebContract.Read and ThirdwebContract.Write can now take in full or partial method signatures:
  • var name = await contract.Read<string>(method: "name", ...) still works.
  • var name = await contract.Read<string>(method: "function name() view returns (string)", ...) now also works.
  • var name= await contract.Read<string>(method: "name() view returns (string)", ...) now also works.
  • var result = await contract.Write(..., method: "claim(address, uint256, address, uint256, (bytes32[], uint256, uint256, address), bytes)", ...) now also works.
  • We still recommend using our awesome extensions for common standards such as contract.DropERC20_Claim to make life easier!
• Added support for ERC20 Paymasters.
