Luca BertonCrypto Meets Regulatory Compliance
The Markets in Crypto-Assets Regulation (MiCA) brings crypto-asset service providers (CASPs) under EU financial regulation. And DORA applies to MiCA-regulated entities. This means crypto exchanges, custodians, portfolio managers, and transfer service providers must implement the same ICT risk management, incident reporting, and resilience testing as traditional financial institutions.
For an industry built on "move fast and break things," DORA's requirements represent a fundamental operational shift.
DORA Requirements for Digital Asset Infrastructure
Wallet & Key Management Infrastructure
- HSM-backed key management: Private keys for custody must be protected by hardware security modules — no software-only key storage for regulated custody
- Multi-signature schemes: Transaction approval requiring multiple key holders — prevents single points of compromise
- Key ceremony documentation: Formal, witnessed procedures for key generation, backup, and rotation
- Disaster recovery for keys: Documented recovery procedures with tested backup restoration. Key loss = permanent asset loss.
- Cold/warm/hot wallet architecture: Risk-tiered custody with the majority of assets in cold storage
Blockchain Node Infrastructure
- Node redundancy: Multiple full nodes across availability zones — a single node failure shouldn't affect service
- Chain monitoring: Real-time monitoring of blockchain state — reorganisations, forks, and mempool analysis
- RPC infrastructure: Redundant RPC endpoints with failover. Don't depend on a single Infura/Alchemy endpoint.
- Block data retention: Full archival nodes for transaction history and audit trail (DORA Art. 12 — logging requirements)
Smart Contract Risk Management
- Audit requirements: Independent smart contract audits before deployment (not just internal review)
- Formal verification: Mathematical proof of contract correctness for high-value contracts
- Upgrade mechanisms: Proxy patterns or modular architecture allowing security patches
- Monitoring: Real-time monitoring of contract interactions for anomalous behaviour (MEV attacks, flash loan exploits)
Incident Reporting for Crypto
DORA incident classification for digital assets:
- Major incident: Loss of customer assets, exchange downtime affecting trading, key compromise, smart contract exploit
- Reporting timeline: Initial notification within 4 hours, intermediate report within 72 hours, final report within 1 month
- Unique challenges: Blockchain transactions are irreversible. A smart contract exploit may result in permanent, unrecoverable loss. Traditional incident response (rollback, restore from backup) may not be possible.

View on Amazon →Infrastructure Architecture
- Kubernetes for exchange infrastructure — Matching engine, order book, API gateway on K8s with HA and autoscaling
- Dedicated nodes for blockchain — Full and archival nodes on bare metal or dedicated instances (not shared K8s)
- HSM integration — AWS CloudHSM, Azure Dedicated HSM, or on-premise Thales/nCipher for key management
- Transaction monitoring — Real-time blockchain analytics for AML/CFT compliance (Chainalysis, Elliptic integration)
- Multi-region active-active — Trading infrastructure across at least two regions with < 100ms failover
