Bitcoin Self-Custody. We hold your hand, not your keys.
We help you secure Bitcoin for the long term using cold-wallet setups. From device selection to backup design and recovery planning, we guide you through every practical step. Our service is built for long-term holders who want a custody solution they can understand, verify, and recover independently - without trusting third parties.
We do not assess, recommend, or provide custody guidance for alternative digital assets.
Bitcoin self-custody is unforgiving. Small mistakes can lie dormant for years before causing irreversible loss. So far, an estimated 3.7 million Bitcoin have been lost.
The Bitcoin network itself has never been hacked. Losses stem entirely from management failures - compromised software, lost keys, or operational mistakes.
That's why professional guidance matter. Together, we check the tricky parts and question
assumptions so that you can remain confident and independent.
Good security begins with discretion. Tell us what you want to achieve without sharing your name, holdings, or other sensitive information.
If we are a good fit, we can continue privately online or
arrange a face-to-face consultation.

To send Bitcoin securely, a wallet must generate a unique, unpredictable secret code (called a k-value) for every transaction. A bug in Android’s “SecureRandom” system caused some wallets to reuse these codes or generate predictable ones. By comparing just two affected transactions, attackers could calculate a user’s private key and steal all the funds. Users had to update their apps immediately and move their money to new, secure addresses.
Hackers stole more than $600,000 by compromising the Ledger Connect Kit used by popular cryptocurrency websites. Visitors saw familiar “Connect” or “Sign In” prompts, but the request had been swapped. Clicking the button signed a hidden permission that sent funds to the attackers.
What Coinkite clients thought was a reliable setup turned out to have a fatal flaw. A five-year-old coding error left thousands of wallet seeds vulnerable, resulting in the loss of over 1,800 BTC in just days. Adding at least 100 private dice rolls during setup would have supplied sufficient entropy to prevent this, but most affected clients did not perform this critical step. Attackers did not need to breach the hardware; they simply calculated the weak keys.
Attackers secretly altered code running across websites that used the Adform advertising platform. The malicious code acted like an invisible pickpocket: when someone copied a cryptocurrency address, it replaced it with the attacker’s address. It would even replace the correct address again if the user retried. Because the attack happened inside the website, antivirus software could not detect it. Only checking the destination on the physical hardware-wallet screen could reveal the swap before funds were sent.

We work privately and at your pace. No pressure, no one-size-fits-all solutions. We analyse the risks before you act, and guide you through building custody setups you fully understand. We prioritize a step-by-step approach over automated black boxes. By walking through every step together, we ensure you understand the why behind every strategy, not just the how.
Choose the level of support that matches your situation - from a simple first setup to advanced security planning or ongoing threat updates. We guide you at your own pace, giving you time to make informed decisions while remaining fully in control of your Bitcoin.
Create a Bitcoin seed phrase safely using a high-entropy process and load it into a compatible wallet of your choice. We guide you through the role of entropy and passphrases, preparing a private environment, generating strong randomness and a strong seed phrase.
This focused service covers secure seed creation and loading it into one compatible wallet. It does not include hardware selection, backup design, recovery testing, or transaction guidance. You complete every sensitive step privately; your entropy, seed phrase, passphrase, and private keys are never shared with us.
Set up and test a Bitcoin wallet you understand and can use independently. Across four guided sessions, you choose and prepare your hardware, create your wallet securely, build reliable backups, and practise Bitcoin transactions.
You complete every sensitive step privately and at your own pace. Your entropy, seed phrase, and private keys are never shared with us.
For larger holdings, families, or more demanding security needs. We examine how theft, loss, device failure, or mistakes could affect you, then design practical safeguards. This can include multi-signature custody, separated backups, recovery planning, and inheritance considerations.
The modules are adapted to your threat model and completed at your own pace, with each safeguard reviewed before it becomes part of your live setup.
Every month, we send you a plain-English update tailored specifically to the devices you use. We cut through the noise of the crypto world to tell you:
If a serious security issue or urgent network risk arises, you won't have to figure it out alone. You get:
You can pay in Bitcoin (sats) or GBP. USD and EUR are also accepted.
