Blockrise
Blockrise operates in the threat model where a single compromised key or a custodial counterparty failure can wipe out a lifetime of bitcoin savings. Founded in 2017 and based in Rotterdam, the Netherlands, the company runs a Bitcoin-only financial platform spanning custody, brokerage, wealth management, Bitcoin-backed loans, secured lending, treasury services, and legacy planning. The technical stack centers on HSM-based infrastructure , segregated on-chain wallets, and a semi-custodial custody model that keeps direct ownership with the user while providing institutional-grade key management. For security engineers, the relevant surface area is cryptography, blockchain infrastructure, and custody architecture. The semi-custodial model means users hold direct ownership of their bitcoin - Blockrise manages the security layer via hardware security modules and on-chain segregation, not omnibus pooling. The platform covers the full lifecycle: acquisition through brokerage, yield via lending, collateralized credit through Bitcoin-backed loans, and long-term succession through legacy planning and treasury management. Blockrise holds a MiCAR license under the Dutch Authority for the Financial Markets (AFM), operating within Europe's regulatory perimeter. The client base spans individuals, corporates, and institutional players - each with different key-management expectations and compliance requirements. The company's emphasis on verifiability and transparency maps directly to audit-readiness and proof-of-reserves concerns that define the current custody landscape.
