Terms and attribution

Licence

The contracts are released under the MIT licence. Read them, fork them, deploy them, build on them.

What you build

• Read every market's state from the chain, without asking us.
• Index our events and republish what you derive.
• Build interfaces, bots, dashboards, analytics and alerting on the contracts.
• Route trades through buyOnMarket, or through a market's own buy and sell.
• Quote our formulas, addresses and event signatures.

No API key, no permission, no agreement. The integration surface is minimal and entirely on chain.

What you do not claim

• Do not present yourself as UNPRICED, or as operated by us. Third-party services are third-party services. Our name, mark and domain do not imply that we run, endorse or vouch for what you built.
• Do not present a fork as the real thing. Copies exist. Their contracts are not the addresses in Contracts.
• Do not show a marginal price as a realisable exit. Display exitValue alongside it. This is the one thing we ask of every interface built on this protocol, and the reason exitValue lives on chain.
• Do not show earnings you cannot derive from the chain or the index. No projected, estimated or motivational figures presented as amounts owed.
• Do not present UNPRICED as a bet, a prediction market, or a wager on a result. It is none of those, and the description misrepresents the product.

Changes

Contract addresses change when a factory is redeployed, and the fee preset is replaced for future markets. Both are announced, and both are readable on chain. This documentation describes what is deployed. When it and the chain disagree, the chain is right.
