Crypto & Digital Asset
Safeguarding
Protecting cryptocurrency wallets, NFT collections, and digital asset portfolios from theft, social engineering, SIM-swap attacks, and sophisticated phishing campaigns.
Request a Private ConsultationWallet & Key Security
Securing private keys, seed phrases, and hardware wallets against theft, loss, and coercion. We design multi-layered key management architectures that eliminate single points of failure — ensuring your digital assets remain protected even if one security layer is compromised.
Transaction Security
Protecting against interception and social engineering during transfers. From address verification protocols and clipboard hijacking prevention to SIM-swap defence and phishing detection — we secure every step of the transaction lifecycle to prevent irreversible losses.
Why this matters
Cryptocurrency operates without a safety net. There is no bank to call, no fraud department to file a claim with, and no way to reverse a transaction once it is confirmed. The security of your digital assets depends entirely on the measures you put in place before an attack occurs.

What's Included
Protecting your digital wealth
01
Digital Asset Security Audit
A comprehensive assessment of your entire digital asset ecosystem — from wallet configurations and exchange accounts to the devices and networks you use to manage your portfolio.
- Complete wallet inventory and security assessment covering hardware wallets, software wallets, exchange accounts, and any custodial arrangements — evaluating the security posture of each against known attack vectors
- Seed phrase and private key storage evaluation assessing how your recovery phrases and keys are generated, stored, and protected — identifying single points of failure that could result in total asset loss
- Exchange account security review covering authentication methods, API key permissions, withdrawal whitelists, and session management to ensure your exchange presence is hardened against account takeover
- Device and network assessment of the computers, phones, and internet connections you use to manage digital assets — identifying malware risks, insecure configurations, and network vulnerabilities that could compromise transactions
02
Wallet Architecture & Key Management
Designing and implementing a secure wallet architecture that protects your digital assets through defence in depth — ensuring no single point of failure can result in total loss.
- Multi-signature wallet configuration requiring multiple independent approvals for high-value transactions — preventing a single compromised key from enabling unauthorised transfers
- Hardware wallet setup and hardening including firmware verification, PIN and passphrase configuration, secure initialisation procedures, and physical storage recommendations for long-term holdings
- Geographic key distribution strategies spreading signing keys across multiple secure locations and jurisdictions — protecting against physical theft, coercion, and single-location disasters
- Inheritance and succession planning for digital assets including dead-man switches, trusted executor protocols, and time-locked recovery mechanisms that ensure assets remain accessible to your heirs
03
Operational Security for Transactions
Implementing rigorous operational security procedures for every interaction with your digital assets — from routine transactions to large transfers and new platform onboarding.
- Transaction verification protocols including address confirmation procedures, test transaction requirements, and real-time monitoring to detect address poisoning, clipboard hijacking, and man-in-the-middle attacks
- SIM-swap protection through carrier PIN locks, number porting freezes, hardware security key migration for all accounts, and authentication app hardening to eliminate the mobile number as a single point of failure
- Phishing and social engineering defence including email filtering, domain monitoring for typosquatted crypto platforms, and tailored awareness training focused on the specific tactics targeting high-value crypto holders
- Incident response planning with pre-agreed procedures for suspected compromise — including emergency asset transfer protocols, exchange freeze contacts, and forensic investigation capabilities to trace and potentially recover stolen funds
Who This Is For
Designed for those who need it most
HNWIs & Entrepreneurs
Safeguarding the digital asset portfolios of entrepreneurs and investors from theft, social engineering, and SIM-swap attacks
UHNWIs & Family Offices
Institutional-grade security for significant cryptocurrency holdings and family office digital asset strategies
Wider Network
Protecting the advisors, brokers, and associates who handle digital asset transactions on behalf of high-net-worth clients
Irreversible transactions mean
irreversible losses.
In the world of digital assets, there is no undo button. A single compromised key, a single successful phishing attack, or a single moment of inattention can result in the permanent loss of millions. Security must be absolute because the consequences are.
Key questions
Common questions from principals about cryptocurrency security, wallet protection, and safeguarding digital asset portfolios.
How do you secure hardware wallets and seed phrases?
We implement a layered approach to hardware wallet security. This includes verified device procurement from official sources, secure initialisation in air-gapped environments, strong PIN and passphrase configurations, and firmware integrity verification. For seed phrase storage, we design bespoke solutions based on your requirements — from metal backup plates stored in separate secure locations to Shamir Secret Sharing schemes that distribute your recovery information across multiple trustees, ensuring no single person or location holds complete access to your assets.
Can you protect my exchange accounts from being compromised?
Yes. Exchange account security is a critical layer of our programme. We migrate all authentication to hardware security keys, implement IP-based access restrictions where supported, configure withdrawal address whitelists, review and restrict API key permissions, enable all available security features, and establish monitoring for unauthorised login attempts. We also assess the exchange’s own security track record and recommend asset distribution strategies that limit your exposure to any single platform.
What is a SIM-swap attack and how do you prevent it?
A SIM-swap attack occurs when an adversary convinces your mobile carrier to transfer your phone number to a SIM card they control. This allows them to intercept SMS-based two-factor authentication codes and gain access to your accounts. We prevent this by eliminating SMS-based authentication entirely, migrating to hardware security keys and authenticator apps, implementing carrier-level protections including account PINs and port-freeze requests, and monitoring for indicators that a SIM-swap may be in progress.
What if I suspect my wallet has been compromised?
Time is critical in a suspected crypto compromise. Our incident response protocol includes immediate asset transfer to pre-configured emergency wallets, exchange notification to freeze accounts and flag suspicious addresses, blockchain forensics to trace the movement of funds, and coordination with law enforcement and recovery specialists where applicable. Having these procedures pre-established and tested before an incident occurs is essential — delays of even minutes can mean the difference between recovery and total loss.
Can you help with NFT and DeFi security?
Yes. NFT collections and DeFi positions carry unique risks including smart contract vulnerabilities, approval exploits, and marketplace phishing. We assess the security of your NFT storage, review smart contract approvals that may grant excessive permissions to third-party contracts, implement wallet segregation strategies that isolate high-value NFTs from active trading wallets, and monitor for targeted phishing campaigns that spoof popular NFT marketplaces and DeFi platforms.
How do you handle digital asset inheritance planning?
Digital asset inheritance requires careful planning because the same security measures that protect your assets can also lock them away permanently if you become incapacitated or pass away. We design inheritance frameworks that balance security with accessibility — including encrypted instructions for trusted executors, time-locked recovery mechanisms, multi-party key sharing arrangements, and legal documentation that integrates with your broader estate planning. Everything is tested to ensure your heirs can actually access the assets when the time comes.
