# Unreal SDK Quickstart

> Add a Sequence-powered smart wallet to your Unreal game.

## 🛠️ Step 1: Install Sequence's Unreal SDK

Download [v3 from the SDK's GitHub Releases](https://github.com/0xsequence/sequence-unreal/releases/tag/v3.0.0)
to access Ecosystem Wallets. You can download one of the `.zip` files, depending on the Unreal Engine version you are using.

To see Ecosystem Wallets in action, [try our Built-In Demo.](/sdk/unreal/wallets/ecosystem-wallet/setup#try-our-built-in-demo)

## 🔑 Step 2: Configure your Unreal Project

Go to [sequence.build](https://sequence.build), sign up or log in, and create a new project. You can follow the [Builder Getting Started](/solutions/builder/getting-started) guide to get a step by step flow.

Follow our [Unreal Setup](/sdk/unreal/wallets/ecosystem-wallet/setup) to configure the Unreal SDK.

## 💼 Step 3: Create a Session with Permissions

To send a transaction to a specific contract, you must first create a session with the required permissions.

  <Tab title="C++">
    ```cpp theme={null}
    const FString Target = TEXT("0x33985d320809E26274a72E03268c8a29927Bc6dA");
    const int64 ChainId = 421614;
    const int64 Deadline = 1856724472000;
    const int64 ValueLimit = 0;

    UContractPermissions* Permissions = UContractPermissions::CreateContractPermissions(ChainId, Target, Deadline, ValueLimit);
    ```
  </Tab>
</Tabs>

Next, use the permissions object to call an authentication function — for example, Sign In with Google.
If you prefer, you can also leave the permissions empty to create an implicit session.

    const TSuccessCallback<bool> SuccessCallback = [this, OnSuccess](bool Result) { };
    const FFailureCallback FailureCallback = [OnFailure](const FSequenceError& Error) { };

    USequenceConnect* Connect = NewObject<USequenceConnect>();
    Connect->SignInWithGoogle(Permissions, SuccessCallback, FailureCallback);
    ```
  </Tab>

## 📨 Step 4: Send Transactions

Finally, let’s use our wallet session to send a transaction to the contract address specified in our permissions.

    const FString FunctionSignature = TEXT("explicitEmit()");
    const int64 Value = 0;
    const TArray<FString> Values = { };

    UContractTransaction* Transaction = UContractTransaction::CreateContractTransaction(To, Value, FunctionSignature, Values);
    ```
  </Tab>
</Tabs>

Next, use the transaction object and pass it to the SendTransaction function.
Optionally, if you're interacting on a mainnet without gas sponsorship, you can [fetch fee options](/sdk/unreal/wallets/ecosystem-wallet/blockchain-interactions#get-fee-options) first.
