Sequence Wallet Authentication

Gamers LAB offers native support for Sequence wallet-style authentication, enabling seamless web3 login flows for players through its REST server infrastructure. This integration provides a secure and straightforward method for identifying and authorizing users within blockchain-enabled games.

1. Wallet Sign-In with Sequence

Authentication begins by obtaining a Sequence Wallet IdToken (JWT). This token is generated on the client side via the Sequence SDK and submitted to the Gamers LAB REST server for verification.

Once verified, the server issues a custom Gamers LAB JWT, which contains:

• A signed verification message

• The player’s unique playerIndex

• The associated applicationId

• Additional session-specific metadata

This JWT is used to authenticate all subsequent REST calls. The original Sequence Wallet IdToken is single-use and can be discarded after the Gamers LAB JWT has been issued.

2. Developer References

To assist developers with integration, Sequence provides documentation and code examples for both major engines:

• Unreal Engine Guide – Unreal Guide

• Unity Engine Guide – Unity Guide

3. Example: Unity Authentication Call to Generate JWT

// Example: Getting the Sequence JWT token from the Unity game client
const jwt = await wallet.getIdToken();

4. Submit to Gamers L.A.B. Rest Server

Send the obtained JWT to the following endpoint:

// REST POST Request
POST /api/Auth/wallet/login/sequence-jwt

Request Body:

{
  "jwt": "<your_sequence_id_token_here>"
}

Server Response

If valid, the Gamers LAB server will return a platform-specific JWT.

This JWT should be stored securely and used in the Authorization: Bearer <token> header for all future authenticated API calls.
