Cubist
Cubist builds hardware-backed key management and embedded wallet infrastructure for Web3. Its flagship product, CubeSigner, generates and seals cryptographic keys inside FIPS 140 HSMs running in AWS Nitro Enclaves and enforces transaction approvals with a programmable Policy-as-Code engine. The CubeSigner REST API spans organizations, users, roles, keys, policies, contacts, sessions, and multi-factor approvals, plus multi-chain signing for EVM (Ethereum, Avalanche), Bitcoin/Taproot, Solana, Sui, Tendermint, Ethereum validators (eth2), and Babylon Bitcoin staking. Authentication is a two-stage OIDC-to-session-token exchange with least-privilege scopes and step-up MFA. Cubist is backed by Amplify Partners and Polychain and is SOC 2 compliant.
Cubist publishes 30 APIs on the APIs.io network, including Account API, Accounts API, Audit API, and 27 more. Tagged areas include Company, Developer Tools, Key Management, Wallets, and Digital Signatures.
Cubist’s developer surface includes documentation, engineering blog, support, authentication, sandbox, CLI, and 24 more developer resources.
