Foundation

name: Foundation
description: >-
  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.
