Oracle And Hybrid Games

Not every game that fits Midgard will be fully onchain or fully native to Starknet.

Midgard still wants an oracle or hybrid path for games that are:

off-chain
semi-onchain
on another chain
not yet ready to implement the full Starknet-native flow

Why this matters

Midgard works best with games that produce clear scores and short sessions.

That includes a much wider set of games than the current Starknet-native ecosystem alone. If Midgard only supported fully onchain Starknet games, a large part of the design space would stay closed.

Current state

The current live contract path is still the Starknet-native one:

factories create sessions through a game contract
challenges create sessions through a game contract
activation and settlement read score and game_over directly from that contract

The frontend contains experimental local game surfaces, but those are not yet a published contract-supported builder path for hybrid or off-chain games.

What the oracle path is for

The custom oracle is meant to let Midgard work with games that cannot rely on Starknet contracts alone for score truth.

That includes:

browser games that run off-chain
games with a mix of off-chain gameplay and onchain settlement
games hosted on other chains
games that want Midgard’s market layer without rewriting their core runtime for Starknet

How to think about the architecture

Starknet-native games

Use the standard embeddable route described in Game Integration and in the official Provable Games EGS docs.

Hybrid and external games

Use the oracle path.

The oracle layer is intended to:

attest to the session being valid
provide the score Midgard should settle against
let Midgard preserve the same factory and challenge economics even when gameplay happens elsewhere

What this unlocks

This is the path that makes Midgard bigger than a Starknet-only game adapter.

It opens the door to:

Midgard-native arcade games that are mostly off-chain
semi-onchain games with stronger UX than pure contract execution
game studios outside Starknet that still want score-backed challenge markets

Practical guidance

If you are building a fully onchain Starknet game, start with Game Integration.

If you are building something hybrid, off-chain, or cross-chain, treat the oracle route as a roadmap conversation with the Midgard team rather than a ready-made integration surface today.
