Your custody provider shouldn't also be your counterparty

In a market shaped by FTX-style collapses and $1.5 billion exchange breaches, institutions need custody they can verify.

Fully Open-Source

Every line of code is auditable. No closed-source security modules, no proprietary MPC implementations, no blind trust required. Verify everything.

No Exchange Conflict

Unlike Coinbase and Gemini, Blockstream is not an exchange. Your assets are held by a pure infrastructure provider with no competing interests.

Bitcoin-First Expertise

Over a decade focused on Bitcoin infrastructure. Deep specialization rather than spreading thin across hundreds of tokens and chains.

Multi-Sig Security

Battle-tested multi-signature architecture. Proven, transparent, and mathematically verifiable. No proprietary MPC black boxes.

Hardware-Rooted

Built on Blockstream Jade hardware security. Air-gapped signing, secure key generation, and tamper-evident design from silicon up.

Segregated Assets

Bankruptcy-remote, segregated custody architecture. Client assets are never commingled. Cryptographic proof-of-reserves on demand.

Built for the problems institutions actually face

From regulatory compliance to 24/7 operations, Blockstream Enterprise addresses the real barriers to institutional Bitcoin adoption.

Regulatory clarity, not regulatory burden

Banks spend years navigating SAB 122, OCC guidance, and state-level patchwork regulations. Blockstream provides pre-built compliance frameworks so you can move at the speed of the market.

  • SAB 122 and OCC-aligned custody frameworks
  • Automated BSA, AML, CTF, and OFAC compliance
  • MiCA-ready for European operations
  • Travel Rule implementation included

Compliance Ready

Pre-built frameworks for global regulatory requirements

Security you can verify, not just trust

$2.5 billion was stolen from exchanges and custodians in 2025 alone. Closed-source security failed. Open-source, hardware-rooted architecture eliminates the single points of failure that made those breaches possible.

  • Air-gapped signing with Jade hardware modules
  • Multi-signature governance with configurable policies
  • Real-time proof-of-reserves and cryptographic attestation
  • Zero breaches. Open-source track record since 2014.

Verifiable Security

Open-source, hardware-rooted, mathematically proven

Go live in weeks, not years

Deutsche Bank and Citi each spent two years building custody infrastructure. Blockstream's API-first platform means you can integrate institutional-grade custody into your existing systems without rebuilding from scratch.

  • API-first architecture for seamless integration
  • 24/7 monitoring and incident response
  • Automated reconciliation and client reporting
  • White-label options available

API-First Platform

Integrate with your existing systems in weeks

Designed for institutions that can't afford to trust

Every component is auditable, every transaction is verifiable, and every key is protected by hardware you can inspect.

01

Segregated Custody Architecture

Client assets are cryptographically isolated. No commingling, no rehypothecation. Each account is independently verifiable through on-chain attestation.

02

Multi-Signature Governance

Configurable m-of-n signing policies with hardware-enforced authorization. Geographic distribution of signing keys across secure facilities.

03

Air-Gapped Key Management

Private keys never touch an internet-connected device. QR-code and SD card based transaction signing with Blockstream Jade hardware modules.

04

Liquid Network Integration

Confidential transactions on Blockstream's Liquid sidechain for institutional settlements. Faster finality, lower fees, and transaction privacy.
