Foundation is a creator-focused NFT marketplace built on Ethereum that enables digital artists to mint, showcase, and auction unique digital artworks. The platform provides a GraphQL API via The Graph protocol for querying artwork, auctions, bids, collector profiles, offers, buy-now listings, and edition drop data. Foundation smart contracts remain live on Ethereum mainnet, and the subgraph continues to index on-chain activity for programmatic access.
