Cathena
Cathena builds infrastructure for composable onchain markets. It turns uncertainty into a programmable primitive by allowing two or more outcomes to combine, form markets through liquidity, and settle transparently on-chain.

설명
Cathena is an infrastructure layer for composable outcome markets. Instead of traditional prediction markets which are isolated applications, Cathena treats outcomes as programmable primitives that can be created, combined,, and settled onchain.
At the core of Cathena is the idea of programmable uncertainty. Any uncertain event — such as an asset outperforming an index, oil moving above a target price, gold beating another commodity, or an AI company outperforming the stock market can be represented as an on-chain market. These markets are formed naturally by liquidity, priced through user participation, and settled transparently using agents and verifiable data sources.
This idea was formed at the start of the hackathon observing that users didnt actually care if Anthropic price for example was at 1 trillion valuation, rather if holding Anthropic will outperform the broader stock index.
Cathena’s first version was built during a hackathon as a private AI market against a stock index, allowing users to express views on whether AI related assets could outperform broader market benchmarks. This demonstrated the core primitive: combining outcomes into markets that are composable, financialized, and capable of being settled through autonomous infrastructure.
The broader vision is to make outcome markets as composable as tokens, liquidity pools, and lending markets in DeFi. Developers, traders, liquidity providers, and AI agents should be able to build on top of these outcome primitives to create new markets, hedge real-world risk, generate intelligence, and allocate capital.
Cathena is not just a prediction market interface. It is a foundation for programmable markets where uncertainty itself becomes an on-chain building block.
