WHY NOW

A cold wallet is not enough.

Recent thefts were a reminder: security depends on your whole setup, not just the device.

NOT ONLY BITCOIN

You hold ETH, SOL or other coins?

We also help with Ethereum, Solana and altcoins, from simple steps to the most robust setups.

01

Cold wallet + passphrase

A simple, effective step for most coins: keys kept offline, protected by an extra secret word.

02

Shared approval, 2 of 3

Spending needs 2 of 3 keys. On Ethereum and Solana this uses multi-signature accounts, which work differently from bitcoin: we explain the differences.

03

Mixed portfolio

One clear plan for your bitcoin and other coins, including how your family gets access.

Options and maturity differ by blockchain; we review your situation before recommending anything.

THE PRINCIPLE

Three keys.
Two signatures.
A different way to hold.

In a “2-of-3” setup, two of the three keys are required to authorise a transfer. A single compromised key is not enough to spend the bitcoin.

It is not magic protection: the choice of devices, key independence, backups and procedures make all the difference.

Key AIndependent
Key BIndependent
Key CIndependent

Two signatures authorise the transaction.
The third key can stay offline and separate.

THE PROGRAMME

Understand. Configure. Test.

01

Choose your organisation

Understand 2-of-3, separate the keys and identify the risks in your current storage.

02

Master the operations

Prepare a configuration, verify addresses and practise signing with a test amount.

03

Plan for recovery

Organise backups, keep the wallet information and prepare a recovery and inheritance procedure.

Review my setup

Before you start

Does multisig remove all risks?

No. It reduces some risks linked to a single key, but poor organisation or incomplete backups can still lead to a loss.

Do I need a multisig wallet already?

No. The training can start from the fundamentals or from your existing setup. We clarify the level and equipment before the session.

Will you have access to my bitcoin?

No. You keep your keys and control of your funds. Never send us recovery words or private keys.

Your cold wallet. Your security, checked.
