Independent advisory for crypto & digital assets
The bridge between traditional finance and blockchain.
Over $88M in bitcoin swept out of cold wallets.
Weakly generated seeds let an attacker rebuild private keys and drain thousands of addresses — without ever touching the device. A single-signature wallet is one point of failure. Multisig removes it.
- Urgent diagnosis: whether your addresses are exposed
- 1-to-1 guided migration to a 2-of-3 multisig vault
- Keys split across locations and vendors, backup and inheritance included

The solution
What multisig is, in plain terms.
A normal wallet depends on one key. Whoever gets it takes everything. A multisig wallet requires several separate keys to authorise a transfer. We recommend 2-of-3: three keys exist, any two are enough to sign.
3 keys, 3 locations
Three devices from different manufacturers, stored in three separate places. No single vendor flaw can compromise the vault.
2 signatures per transfer
Every payment needs two keys. A thief holding one key can't move a satoshi.
Backup built in
Lose a key? The other two still open the vault. No single point of failure, no permanent loss.
Single-signature wallet
- One key = one point of failure
- Weak or leaked seed = instant drain
- Lost backup = lost funds
- No separation of duties within the family
2-of-3 multisig vault
- Compromising one key isn't enough
- Different vendors = no shared risk
- Losing one key is fully survivable
- Inheritance organised via the third key
Yes, it's more complex to set up. That's exactly why we do it with you, step by step, on your own devices. We never hold a key.

We never custody your funds
You remain the sole owner and sole holder of your keys. Our role stops at advice.
- 02

No retrocession, no product to push, no paid partnership with any sector player.
- 03
Notarial confidentiality
NDA signed before any substantial exchange. The discretion expected by the families we serve.

Fixed, disclosed fees
No percentage on your assets. A transparent quote from the very first meeting.
Inheritance plan
Your keys vanish with you.
It is the most brutal reality of digital assets. Without a rigorous inheritance plan, your bitcoin, ether and stablecoins will reach no one. No bank, no notary, no court can recover a lost seed phrase. Your heirs will inherit a fortune they will never touch.
Without a plan, here is what happens.
No one knows what to look for
Your loved ones are unaware of the wallets, exchanges and cold storage devices — let alone the amounts involved.
No professional can step in
Neither notary, lawyer nor banker has any legal mechanism to recover a private key. Code does not forgive.
Poorly protected seeds are lost — or stolen
A paper in a safe is not a strategy. A photo on a phone is a gift to attackers.
Tax authorities will still claim their share
Heirs remain liable for inheritance duties — even on assets they cannot access.
Our framework
A complete inheritance plan, designed as a notarial act.
Four pillars, calibrated for each family, validated with your notary and tax counsel.
- 01 / 04
Confidential inventory
Exhaustive mapping of your holdings: wallets, exchanges, cold storage, NFTs, DeFi positions. An encrypted, auditable document, updated with you every year.
- 02 / 04
Secured technical architecture
Multi-signature, Shamir Secret Sharing, Casa- or Unchained-grade setups, time-locks. No seed on a single support. No dependency on any single person.
- 03 / 04
Tailored legal framework
Coordination with your notary: tailored will, lasting power of attorney, fiducie or trust depending on your jurisdiction (FR, CH, US, UAE, SGP). Nothing improvised.
- 04 / 04
Activation protocol
A clear handover guide for your heirs or executors: who, when, how, with what proofs. Tested and rehearsed with your family, while you are still here.
Crypto without an inheritance plan is not wealth. It is a bet on your longevity.
We are one of the few firms treating this subject with the same rigour as a complex real-estate succession — always in coordination with your notary, never in their place.
Our conviction
The bridge between traditional finance and the world of digital assets.
Digital assets are not a fad. They are gradually becoming a new asset class, to be integrated with method into your wealth strategy — if you decide so.
Our role is not to sell you a crypto. We help you understand, organise and protect your digital wealth, in coordination with your existing advisors.
