Marketplace

Meridian Marketplace

White-label NFT marketplace with custom fee logic and creator royalty enforcement.

Meridian is a white-label trading venue: listings, offers, auctions, and settlement with fee routing and royalty-aware order paths - designed so creators keep expected economics across aggregators.

Technology stack

Technology stack

  • Solidity
  • Hardhat
  • The Graph
  • Reservoir
  • Polygon

Representative technologies from the delivery-not an exhaustive inventory of every dependency or internal tool.

Challenge

The operator needed custom fee tiers without opening royalty bypass vectors - and subgraph-backed discovery that stayed consistent under reorgs and high listing volume.

Approach

Solidity marketplace cores on Hardhat with Reservoir-compatible aggregation hooks, The Graph indexing for orders and fills, and regression tests against operator-filter and ERC-2981 edge cases.

Outcome

Placeholder programme narrative - verify before publish. Stated headline: $92M trading volume processed across 200+ collections with zero royalty bypass incidents.
