Crypto custody
built for the
quantum era
A hybrid MPC + TEE wallet for B2B organizations that need enterprise-grade security — and a 30-year guarantee that it stays that way.
Hardware-isolated signing for high-value transfers
The cold tier is an air-gapped device that signs transactions in complete isolation — no network connection, no shared memory, no attack surface.
Large transfers require physical approval on the device before any funds move. The prototype uses post-quantum SPHINCS+ signatures so the security holds even against future quantum hardware.
Air-gapped cold wallet — transaction approval interface
Three tiers. One custody policy.
Each tier is optimized for its risk level — hot for speed, warm for governance, cold for maximum security.
Hot Wallet
Instant payments and high-frequency transactions with programmable spending limits. Sub-30ms signing, 100 TPS.
Warm MPC
Multi-party threshold signing — no single point of key compromise. Distributed approval across geographically separated nodes.
Air-gapped Cold
Hardware-isolated signing for large transfers. Post-quantum SPHINCS+ signatures. Physical approval required.
