Welcome to Keybill

Codiac is pioneering physical cryptocurrency cold storage.

We will be the physical option for all cryptocurrencies, including Bitcoin, in the $10 trillion physical currency market.

How Keybill Works

The token’s public key is printed on the front of the bill, easy for the user to see and verify that the key has value on it.


The token’s private key is printed inside the bill between two layers of metal, effectively a faraday cage to protect and conceal the private key.


The private key can ONLY be accessed by irreparably destroying the KeyBill’s tamper-evident security features.

The Vision

It’s our mission to be the world’s preferred solution for private, offline, physical transactions in cryptocurrencies. Our flagship product, KeyBill, will be the world’s most recognized form of tangible physical cryptocurrency.

01

We intend to make the concept “crypto as money” easy to understand for everyone. Cryptocurrencies feel inaccessible and complicated for a lot of people.

02

We want to create a way to use cryptocurrency without an internet connection.

03

We have a way to make crypto transactions anonymous. At this time, it’s not possible to conduct private Bitcoin transactions.

Our Team

Codiac’s team has industry-leading experience building products and creating logistics systems for physical value.
