Learn more about the technology behind the Codex platform.
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.
Secured by 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 the public Ethereum blockchain, helping to ensure long-term viability and ease of integration with other applications.
Generate Records Automatically
The Codex API allows you to automatically generate Codex records when customers make purchases through your site, which can be given to customers or used as an immutable internal audit system.
Embed Provenance Information on Your Site
You can embed information from a Codex Record directly into your site. This will help to boost customer confidence in the authenticity of the item.
