What is a web3 in-game overlay?
An in-game overlay is a plugin for all popular game engines that:
  • enriches the game experience
  • provides the game developer’s access to user data otherwise unavailable
  • makes user’s onboarding faster
  • increases time spent in-game
  • increases sales by facilitating the buying experience
  • decreases development costs by providing ready-made components

Friends online and offline
Achievements tracker

Achievements are provided by the game developer. The achievements catalog is pre-filled by the game developer’s representative, with each achievement getting an internal AchID. Later during the game process, the game server sends API POST requests to notify the overlay central server about new user’s achievements by their internal AchID.

Data collection

Data we collect from game:
  1. Time spent in game
  2. Achievements

Data game gets from the central overlay server (about user):
  1. Owned in-game NFTs
  2. User’s friends offline and online
  3. User’s wallets

Auth workflow
  1. The game developer obtains an API key from the Overlay Team
  2. The user obtains a special player token in the Overlay account
  3. The game initializes the overlay plugin with the api key
  4. The user opens the overlay and inputs the player token
  5. The plugin connects to the overlay backend, obtains a special overlay token for the session (think of it as a JWT token) and starts bidirectional data transfer
Game Engines Supported
