Varrock VC

Richard backs concentrated, contrarian pre-seed and seed bets in the future of finance. For crypto-native products, he looks for category creation, missionary founders, power-user retention and continuous zero-to-one product innovation. For crypto-adjacent companies, crypto should be an enabling feature inside a much larger industry, led by commercially strong domain experts with superior distribution and unit economics rather than recent crypto pivots.

HashKey Capital

Check: No verified personal check-size range is published. HashKey Capital operates multiple venture, liquid, and multi-strategy vehicles; fund size and disclosed portfolio rounds should not be converted into Yerui's individual authority.

Yerui is a HashKey investment director with documented fund-committee responsibility and a contributor to the firm's technical sector research. The research evaluates infrastructure and applications across ZK, MEV, intents, account abstraction, data availability, Bitcoin, AI x crypto, DePIN, staking, and related Web3 layers. The consistent lens is whether technical design improves transaction flow, verifiability, capital efficiency, decentralization, and real demand.
