Curio Cards emerged in 2017 as a groundbreaking project during the ICO boom, introducing the first smart contract minting system on Ethereum - then called vending machines.
The platform aimed to support artists through tokenized art distribution, offering a white glove service before the existence of NFT marketplaces like OpenSea.
Key innovations:
- First implementation of smart contract minting
- Direct artist payment system
- On-chain art storage
- Peer-to-peer trading model
The project gained recognition from the Ethereum Foundation for its innovative approach to digital art distribution and artist empowerment.
Curio Cards launched in 2017 during the ICO mania, when thousands of new coins were flooding the market, before NFTs were even a term and when on-chain art was a radical idea
