# Unity SDK Setup for Ecosystem Wallets

> Ecosystem Wallet Documentation for Sequence's Unity SDK.

<Steps>
  <Step title={"Configure your Unity Project"}>
    Sign in and create a project on [Sequence Builder](https://sequence.build).

    Next, create a SequenceConfig ScriptableObject in Unity: `Assets` > `Create` > `Sequence` > `SequenceConfig` and place it inside your `Resources` directory.

    Make sure you insert the required fields:

    * **Builder API Key:** Your Project Access Key from your [Builder project.](https://sequence.build/)
    * **Wallet App Url:** The URL of the Ecosystem you want to connect to. If you are unsure, use `https://v3.sequence-dev.app` as a default.
  </Step>

  <Step title={"Create your own Sign-In flow"}>
    You can optionally get the configured auth providers from the Ecosystem directly and check if your target auth method, like Email or Google, is supported.
    Next, let's call an auth method like Google. This will redirect the user to an external browser to authenticate against the Ecosystem.

    You have two options to authenticate. You either create an implicit- or explicit session. You create an implicit session by passing no node to the `Permissions` field.
    Implicit session will only allow transactions to contracts from the Ecosystem. For this demo, let's instead create an explicit session for a specific contract.

    ```csharp theme={null}
    // Let's create the permissions object
    Chain chain = Chain.TestnetAbitrumSepolia;
    Address contractAddress = new Address("0x33985d320809E26274a72E03268c8a29927Bc6dA");
    BigInteger deadline = new BigInteger(DateTimeOffset.UtcNow.ToUnixTimeSeconds() * 1000 + 1000 * 60 * 5000);
    BigInteger valueLimit = 0;

    IPermissions permissions = new ContractPermissions(chain, contractAddress, deadline, valueLimit);

    // Let's call the Sign-In method
    SequenceConnect connect = new SequenceConnect();
    IWallet wallet = await connect.SignInWithGoogle(permissions);

    // Optionally, get the Ecosystem config to check your auth providers
    EcosystemConfig config = await connect.GetEcosystemConfig();
    ```
  </Step>

  <Step title={"Try our Built-In Demo (optional)"}>
    Import the `Demo` sample from Unity's Package Manager. Additionally, checkout our boilerplate
    script [EcosystemWalletLoginWindow](https://github.com/0xsequence/sequence-unity/blob/master/Packages/Sequence-Unity/Sequence/SequenceBoilerplates/Scripts/EcosystemWallet/EcosystemWalletLoginWindow.cs) for integration details.

    You can use this Boilerplate inside your project after importing the Demo Samples. Then, simply call this function:
    `BoilerplateFactory.OpenEcosystemWalletLogin(parent)`

    If you have installed the SDK as a `.unitypackage` file, please locate the Demo scene inside
    Unity's `Project` window under `Packages > Sequence SDK > Sequence > Samples > Demo`
