Curio.Cards

Curio Cards is an online art show and permanent gallery that launched on May 9, 2017. It is the oldest known Art NFT project on Ethereum, featuring 30 unique proto-NFTs from 7 different artists. Curio Cards are referenced alongside CryptoPunks and CryptoKitties within the original ERC-721 Non-Fungible Token Standard, and pre-dates them both.

Given the age of the project, you need to wrap your cards first to use them on OpenSea. Wrapping "upgrades" the card by placing it inside a newer contract which is OpenSea compatible. You can then buy and sell, and unwrap your cards back to the original at anytime. Find out more on the Curio.Cards website, the Docs, or go straight to the Wrapper tool. A 1% artist royalty fee on OpenSea sales was voted in by the community on 3/31/21. 100% of the royalty is split equally across all the artists, with the Curio team and community receiving no part of it.
