Physical coin cold wallet with intrinsic value
CryptoCoin is our research project dedicated to physical cold wallets with intrinsic value. We explore the transition from the physical striking of coins to digital imprinting, creating tangible objects that secure your digital assets.
The Mantra and Vision
Mantra: « EX – MINIMIS – MULTA » (From the minimum, many — Making a maximum out of the minimum)
We posit that the decentralized metal coin is the democratic embodiment of currency. Our artistic approach consists of sealing the entropy of an HD Wallet (24-word Master Seed) into metal. This physical medium allows for the generation of an infinite number of distinct wallets through the use of a BIP39 passphrase (the famous « 25th word »), obtained via a Diceware protocol (8 words minimum).
Just as the bee stores its nectar within a wax cell, CryptoCoin crystallizes digital value within the density of metal. A secret engraved, yet protected by the HIPS (Hidden In Plain Sight) principle thanks to the passphrase.

Project Objectives
- Historical Convergence: Merging traditional numismatics with the crypto-asset ecosystem.
- Materializing Value: Forging physical coins endowed with intrinsic value (metal and art).
- Secured Tangibility: Developing physical « Cold Wallets » that are tamper-proof and enduring.
