About Kash
Kash operates a prediction marketplace at app.kash.bot where users buy and sell shares in real-world outcomes, including sports, crypto prices, politics, technology, and cultural events. Markets use an automated market maker, settle in USDC on Base, and support multi-outcome markets, leverage, limit orders, social trading, AI-assisted market creation, leaderboards, and creator incentives. Users can trade directly through the app or reply and quote-post on X using Kash's trading account. The platform serves individual traders, creators, online communities, and business or ecosystem partners that embed or create markets.
Skills
About the Role
Build the zero-knowledge infrastructure behind prediction markets, including circuits for market resolution, privacy-preserving proofs, cryptographic primitives, zkTLS, proof systems, circuit optimization, onchain integrations, and security architecture.
Requirements
- 3+ years working with zero-knowledge proof systems
- Strong experience with Circom, Noir, or similar DSLs
- Deep understanding of constraint systems, R1CS, and circuit optimization
- Familiarity with zkTLS, attestation protocols, or oracle design
- Solid foundation in cryptography and mathematics
- Experience with Solidity and EVM integration is a plus
- Contributions to open-source ZK projects are a bonus
Responsibilities
- Design and build ZK circuits for market resolution and verification
- Implement zkTLS and proof systems for trustless data attestation
- Optimize circuit performance and proving times
- Work with smart contract engineers to integrate proofs onchain
- Research and prototype cryptographic approaches
- Contribute to security architecture and threat modeling
