Cubist
Cubist is a security-first Web3 infrastructure company that builds hardware-backed key management and confidential compute for digital assets. Its flagship platform, CubeSigner, keeps cryptographic keys sealed inside secure hardware (HSMs and AWS Nitro Enclaves) while giving developers low-latency signing through revocable sessions and a programmable policy engine - resolving the old tradeoff between cold-wallet security and hot-wallet speed. Founded by applied cryptographers and security researchers from Carnegie Mellon and UC San Diego who designed primitives underlying Ethereum and Avalanche, Cubist serves staking providers, DeFi protocols, bridges, and institutions building on internet capital markets.
