The [Curio Cards](https://curio.cards) project is an online art show and the First Art NFTs on Ethereum, launched on May 9, 2017. Curio features 30 unique series of cards from 7 different artists. Curio Cards are referenced with CryptoPunks and CryptoKitties in the original ERC-721 Non-Fungible Token Standard, and pre-dates them both. Join the [Curio Discord](https://discord.curio.cards) and check out the [Curio Docs](https://docs.curio.cards) to find out more.
Given their age, Curio Cards needed to be wrapped to work with OpenSea. If you purchased cards before March 2021 and Not on OpenSea, you can wrap them [here](https://wrap.curio.cards). Otherwise, you don't need to do anything. All cards on OpenSea are already wrapped.
A 1% artist royalty on OpenSea sales was voted in by the community on 3/31/21. 100% of this royalty goes the original artists.
