Prediction-market protocol

One protocol. Every way to ask the crowd.

Seer turns questions into tradable outcomes and prices into signals. Five applications run on the same contracts, the same outcome tokens and the same oracle — each one tuned to a different kind of decision.

The stack

Five questions, one foundation

Every app is a lens on the same thing: a market whose price you can read. Pick the app by the question you are asking.

Outcome tokensERC-20 per outcome, built on Conditional Tokens — any wallet or AMM can hold and trade them.

Market typesCategorical, multi-categorical, scalar and multi-scalar — from yes/no to “how much”.

ResolutionReality.eth answers, with Kleros arbitration when an answer is disputed.

Conditional marketsMarkets that only settle if a parent outcome happens — the engine behind Futarchy.

Who it is for

Signals for people who have to decide

DAOs and governors

Read what a proposal is expected to do to your metric — pass versus not — before the vote. The vote stays yours.

Funders and reviewers

Let traders and agents pre-rank a field of grants or submissions so reviewers spend time where it matters.

Risk and treasury teams

Compare market-implied failure probabilities across protocols instead of reading one price alone.

Two readers

Built for people and for agents

AI agents already trade on Seer through Deep. So every Seer interface has a second reader: flip the Agent switch in the top bar and the page you are looking at becomes the structured data behind it. Humans can audit what agents see; agents never have to scrape a UI built for eyes.
