One of my favorite projects in terms of actual innovative ideas - anyone got a quick last 6 months TLDR of what these guys have been up to?

Agreed, super intriguing stuff, and even better for arts/collectibles lovers who spend time in the crypto space.

You've probably seen this:
"Weve decided to Airdrop CodexCoin to our community instead of a community sale.
For all community members who successfully passed our KYC process and provided Codex Protocol with a token wallet address. Those members will each receive an airdrop of 500 CodexCoin tokens.

Anyone who bought CODX in the main sale will receive a refund of the ETH they contributed along with an additional airdrop of 2,000 CodexCoin and the 500 CodexCoin for passing KYC."
