BLOCKSTREAM ENTERPRISE

Qualified Custody for Institutional Bitcoin

Institutional custody is a $1.5T market gated by one question: can you verify the architecture, or are you trusting a vendor's word? Blockstream Enterprise gives regulated custodians hardware-rooted multisig, independent proof of reserves, off-exchange settlement, and a no-rehypothecation guarantee — the credentials clients and examiners require.

Custody architecture, not a black box

Every custody design choice — key generation, signing quorum, recovery path, attestation — is documented, auditable, and built on open primitives. Clients and examiners can verify the architecture rather than trust a vendor's word for it.

  • Hardware-rooted keys generated on air-gapped hardware
  • Independent proof of reserves — attestable without the custodian's cooperation
  • Off-exchange settlement and zero rehypothecation by design

Built for institutional custody operations

Blockstream Enterprise extends the Liquid Federation architecture — production-tested with $1.33B in tokenized financial instruments and 19,000+ BTC bridged — to institutional Bitcoin custody. It plugs into existing custody operations rather than replacing them.

Role-Based Custody Permissions
Distinct roles for proposer, signer, approver, and auditor with cryptographically-enforced scopes. Maps to SoD requirements for SOC 2 and ISO 27001.
icon
Segregated Client Accounts
Per-client wallet structure with on-chain proof of reserves. Each client independently verifies their balance is included without exposing other client data.
icon
Policy-Bound Co-Signing
Blockstream's federated co-signer completes quorum under defined policy — address whitelists, value caps, time delays — without ever holding the institution's keys.

Built for every stakeholder in the decision

A custody decision is made by a committee. Each member is evaluating something different — so each gets proof in their own language, on one verifiable architecture.

Security & Risk
For the technical evaluator
  • Hardware-rooted keys generated on air-gapped hardware
  • Open-source firmware and primitives — review the code, not a spec sheet
  • Federated signing quorum across operationally separated parties
Finance & Audit
For the economic buyer
  • Proof of reserves verifiable independently of vendor attestation
  • Zero rehypothecation — keys and assets stay under the institution's control
  • Off-exchange settlement removes exchange counterparty exposure
Compliance & Legal
For the control owner
  • Role separation maps to SoD requirements for SOC 2 and ISO 27001
  • Per-client segregated accounts with independent reserves attestation
  • Policy-bound co-signing with a cryptographically-enforced audit trail

Designed For

  • Custodial banks and trust companies onboarding institutional Bitcoin programs
  • Funds and state reserves comparing providers against BitGo, Fireblocks, Komainu, and Copper
  • Bitcoin-native platforms building qualified-custody and institutional-staking capacity

Verify, don't trust

Every control on this page is something you or your examiners can check yourselves — the differentiator a black-box custodian structurally cannot offer.

Proof of reserves
Balances attestable independently, any time.
Zero rehypothecation
Client assets are never lent or re-pledged.
Off-exchange settlement
Settle without exchange counterparty risk.
Maps to SOC 2 / ISO 27001
Role separation aligned to your control framework.
