functionSPACE is an open-source protocol and developer framework that provides building blocks for payoff and prediction markets, founded by zerocloo. functionSPACE's Twitter Score is 17 out of 1000 as of September 2026, ranking #57,664 among 486,860 tracked accounts.
functionSPACE was founded in 2025 and received Seed funding from Smape Capital. The protocol lets developers design binary, range, linear, distribution-based, and custom payoff structures tied to numerical events, all on a shared market surface. Its architecture is built as universal trading infrastructure that unifies liquidity, makes market creation permissionless, and handles market resolution internally.
functionSPACE's official developer package is published as @functionspace/core, and its primitives are suited for prediction markets, structured derivatives, research tools, and media applications. A continuous-probability design allows participants to express beliefs as full probability distributions rather than single-point outcomes. The native token $FS is used for bonding within the Reality Market resolution mechanism, which rewards accurate assertions and slashes dishonest ones.
functionSPACE's ecosystem includes live and community-built applications such as propSPACE, indexSPACE, Pulso, and Calibrated. The team includes Tom as CEO, Igor as Research Lead, and Duy Cao as Ecosystem Lead. functionSPACE has been running live prediction competitions, including World Cup events, powered by its own protocol. functionSPACE has published 411 posts and has 3,471 followers as of September 2026, and has been mentioned by 12 accounts a total of 17 times.
