DISCOVER COLDBRICK™

COLDBRICK™ is the preferred choice for those seeking a highly self-custody secure solution to protect their digital assets.


Risks if you don't have it:

TRADITIONAL SINGLE PLATE ISSUE
Despite variations in formats and materials, all plates available in the market share a common problem: they tie words to their positions. The associated risk is that if the device is lost or stolen, the seed phrase is exposed and you could lose your funds in the blink of an eye.

RELYING ON THIRD PARTIES
Entrusting your wealth to companies that possess and control the seed phrase of your wallet(s) and all their contents. Like banks, even the largest and most trusted exchanges and service providers are at risk of bankruptcy; you may not be able to recover what you own.

VIOLATION OF PRIVACY
Without proper protection, your personal and financial information could be exposed to potential privacy breaches, including also the individuals close to you and whom you hold in highest trust.


Main characteristics:

MAXIMUM RESISTANCE
COLDBRICK™ is crafted from a solid piece of 1.5mm thick stainless steel, ready to withstand fires up to approximately 1300°C (an average household fire reaches 650°C), corrosion, and even torsional damage in case of an earthquake.

ESSENTIAL CONCEPT
The dimensions and weight have been carefully designed to make it easy and safe to transport if necessary, as it can be easily concealed.

SECURE PROCESS
Detailed instructions are provided with specific directions and photos that will guide you step by step through the creation of your COLDBRICK™, starting from the paper samples that faithfully reproduce the dimensions and characteristics, moving on to cross-checks and verification of the correctness of the work done, up to the final engraving on the steel plates.

PERMANENT ENGRAVING
Whether you choose to use the included pen, special punches, or a laser engraving machine, your seed phrase and the order of its words will be engraved forever.

COMPATIBILITY
COLDBRICK™ is compatible with all types of wallets, 12- or 24-word BIP-39 Mnemonic Phrase. COLDBRICK™ can therefore be used with all the wallets on the market, such as Coldcard, Ledger, Trezor, MetaMask, and many more.
