Codex Records

Digital Provenance Records

Digital Certificates of Authenticity

Codex records are an online lockbox that allow you to safely store and share information about an item. Add provenance documentation like attestations from appraisers or bills of sale from auction houses. Each piece of information will be stamped on the blockchain.

Secured by the blockchain

Blockchain technology makes attestations and chain of ownership impossible to fake. Every transaction can be verified and the system is unhackable.

Own your data

Codex is built on an open system, meaning that you always control your data, there will be lots of apps that will play nicely with this system, like insurance and loans.
