# windle > windle is a Solana protocol where teams back onchain-verifiable promises with collateral, a YES/NO market prices each promise, and at the deadline the chain decides: ship → collateral returned, YES paid; miss → collateral slashed to NO holders. Status: pre-launch. Markets, prices and amounts shown on the website are illustrative, not live data. Collateral assets, minimums and fees are not decided yet. ## How it works - [Promise](https://www.windle.fun/promise): a team makes an onchain claim anyone can verify, e.g. "Mainnet by Dec 1". - [Collateral](https://www.windle.fun/collateral): the team locks funds it loses if it doesn't deliver. - [Market](https://www.windle.fun/market): buy YES if you believe, NO if you don't; the price is the odds. - [Incentive](https://www.windle.fun/incentive): the only insider is the team, and it profits only by shipping. - [Judge](https://www.windle.fun/judge): at the deadline the chain checks the condition (program deployed, vesting untouched, revenue above N). No oracle votes, no disputes. - [Outcome](https://www.windle.fun/outcome): ship → collateral returned, YES paid; slash → collateral to NO holders. - [Ecosystem](https://www.windle.fun/ecosystem): built on Solana, works with pump.fun tokens. - [Join](https://www.windle.fun/launch): make a promise or back a team. ## Docs - [Documentation](https://docs.windle.fun/): concepts, guides, FAQ, risk disclosure. - [Introduction](https://docs.windle.fun/introduction/) - [How it works](https://docs.windle.fun/how-it-works/) - [FAQ](https://docs.windle.fun/faq/) ## Optional - [Brand kit](https://cdn.windle.fun/): logo marks and app icons. - [API reference](https://api.windle.fun/reference): early, subject to change.
