Wallets & Custody
Wallet Security & Key Management

Crypto assets are more than just digital coins – they are assets with real economic value. Unlike traditional bank accounts, the blockchain world has no central authority that can reverse losses or restore access. Whoever controls the private keys controls the assets. That’s exactly why a well-thought-out wallet and custody strategy is essential.

Service overview

Our services
in detail

From secure wallets to multi-sig architecture – we protect your digital assets.

Hardware wallets

Hardware Wallet Setup

What this service is

Hardware wallets store private keys offline and are among the most secure forms of crypto custody. We guide you through the secure initial setup – from device authenticity verification and secure key generation to final handover.

Why this matters

A hardware wallet is only as secure as its setup. Devices can be tampered with in transit (supply chain attack), malicious or compromised firmware can silently exfiltrate private keys, and an insecurely generated seed puts all managed assets at risk from day one. Common mistakes include activating devices without authenticity checks, storing seeds digitally or skipping passphrases – errors that are often impossible to correct later.

What’s included

  • Device authenticity check (packaging & firmware verification)
  • Secure seed generation with offline-only backup
  • PIN and passphrase concepts
  • Clear training on safe everyday usage

Your concrete benefit

✓Maximum offline security
✓Protection against compromised devices and firmware
✓No dangerous setup errors
✓Long-term protection of larger assets
Custody concepts

Self-Custody & Custody Setup Design

What this service is

We develop individual custody concepts that define: who has access to assets, who approves transactions, and how security and control are distributed.

Why this matters

Without a clear concept, risks emerge: individuals as single points of failure, unclear responsibilities and lack of scalability with growth.

What’s included

  • Self-custody (full self-control)
  • Custody-like models (e.g. shared responsibility)
  • Clear responsibilities & access controls

Your concrete benefit

✓Clear responsibilities
✓More security through structure
✓Suitable for individuals, teams & companies
✓Future-proof & extensible
Multi-sig

Multi-Sig Architectures & Approval Processes

What this service is

Multi-signature wallets require multiple approvals before a transaction is executed. We design and implement these architectures including role and decision processes.

Why this matters

Single keys are a high risk: human error, misuse, loss or extortion. Multi-sig distributes responsibility and drastically reduces risks.

What’s included

  • 2 of 3 directors must approve
  • 3 of 5 key holders give approval
  • Flexible signature schemes as needed

Your concrete benefit

✓Protection against internal & external risks
✓Clear approval processes
✓Ideal for companies, treasuries & family offices
✓Higher trust among partners & investors
Recovery

Backup, Recovery & Emergency Strategies

What this service is

We develop structured backup and recovery strategies so that assets remain accessible even in exceptional situations.

Why this matters

Without a recovery plan: loss of seed = loss of assets. Illness or death = no more access. These risks are frequently underestimated.

What’s included

  • secure seed backups
  • geographic separation
  • documented emergency processes

Your concrete benefit

✓Protection against total loss
✓Clear emergency procedures
✓Security for you & your relatives
✓Long-term value preservation
2FA security

Two-Factor Authentication

What this service is

We implement secure two-factor authentication (2FA) for wallets. We rely on proven methods such as authenticator apps, hardware tokens or biometric methods.

Why this matters

Passwords alone provide insufficient protection. Through phishing, data leaks or social engineering, attackers can gain access to accounts. 2FA adds an additional security layer.

What’s included

  • Setup of TOTP-based authenticator apps (Google Authenticator, Authy, etc.)
  • Integration of hardware security keys (YubiKey, etc.)
  • Backup strategies for 2FA codes and recovery keys
  • Training on secure usage and management

Your concrete benefit

✓Drastically increased account security
✓Protection against phishing and unauthorized access
✓Professional setup with backup strategies
✓Compliance with security standards
