Technical approach
No whole private key, ever
Multi-party computation splits each key into shares held on separate machines; they sign together without the full key existing anywhere.
Shares sealed in secure enclaves
Key shares and policy logic run inside Intel SGX or AWS Nitro enclaves, so even someone controlling the server cannot read them.
Rules enforced before signing
A policy engine checks who is sending what, where and how much, and requires the right approvals before the key shares will sign.
Clients settle with each other
Firms on Fireblocks can find and pay one another directly, and the payments network adds ramps, FX and stablecoin issuers.
