Do you build GDPR-aligned data architecture?

Yes, data minimization, encryption, and access-control patterns are built into our architecture by default for platforms handling EU personal data.

What is MPC wallet technology?

MPC splits a private key into encrypted shares held separately, so transactions can be signed without ever reconstructing the full key in one place.

How is MPC different from multi-signature wallets?

MPC signs off-chain using threshold cryptography and works across all chains uniformly; multi-sig requires on-chain signatures and is chain-dependent.

Is MPC-based custody insurable?

Yes, many institutional insurers now offer coverage for MPC setups that meet defined operational and security controls.

What happens if one key-share server goes down?

As long as the threshold number of remaining shares are available, signing continues uninterrupted — this redundancy is one of MPC's core advantages.

MPC Wallet & Crypto Custody Infrastructure Development in Germany

Traditional key management concentrates risk in one place. Hurain Technologies builds MPC (multi-party computation) custody infrastructure where private keys are split across encrypted shares, so no single device or person ever holds the complete key. Designed for exchanges, funds, and DAOs that need institutional-grade security without a single point of failure. In Germany, that means building to the technical expectations of High-Value Regulated Markets: Banking and payment platforms are typically supervised by BaFin, with data handling governed by GDPR at the technical and organizational level.

Germany Regulatory Landscape

What mpc custody infrastructure buyers in Germany need to know

Banking and payment platforms are typically supervised by BaFin, with data handling governed by GDPR at the technical and organizational level.
Crypto-asset custody and trading activity in Germany has historically required specific licensing consideration under German financial supervision.
Open banking API programs commonly reference PSD2-derived technical standards for strong customer authentication.
We build to these technical expectations while German licensing and data protection sign-off should run through qualified local counsel.

The Challenge

Problems we see teams struggling with

Single point of failure risk

One compromised device or person with access to the full private key can drain funds.

On-chain multi-sig overhead

Traditional multi-signature wallets create blockchain overhead and reduced privacy.

Cross-chain custody complexity

Building custody per blockchain instead of one unified architecture wastes engineering effort.

Institutional audit readiness

Custody setups must meet SOC 2 and ISO 27001 standards, which traditional key storage rarely does.

Operational bottlenecks from over-restrictive approval flows

Custody controls designed without input from the operations team that uses them daily often become so restrictive they get worked around, which defeats their purpose.

Disaster recovery gaps

Key-share backup and recovery procedures that haven't been tested leave a fund or exchange unable to access its own custody in a genuine emergency.

Our Approach

How we deliver mpc custody infrastructure in Germany

MPC/TSS signing

Transactions signed collaboratively without ever reconstructing the full key.

No single point of failure

Key shares distributed across parties and HSMs so one breach cannot compromise custody.

Policy engine

Transaction limits, whitelists, and multi-step approvals enforced automatically.

Role-based access

Granular permissions so team members have exactly the access their role requires.

Multi-chain support

One custody architecture works across Bitcoin, Ethereum, Solana, and other major chains.

Audit logging

Full, tamper-evident logs of every signing event for compliance review.

Tested disaster recovery procedures

Key-share backup and recovery processes designed and rehearsed before they're needed, not documented once and never verified.
