description: Shipyard Software is the DeFi technology company behind Clipper, a decentralized exchange (DEX) designed for
  retail traders that offers blue-chip token swaps with no impermanent loss for liquidity providers. Founded in 2021 by Mark
  Lurie and backed by Polychain and others, Shipyard built market-making technology across eight blockchains before being
  acquired by Sushi Labs in January 2025. Clipper, now governed by AdmiralDAO, exposes a Request-for-Quote (RFQ) swap API
  for DEX aggregators and a Graph-hosted GraphQL subgraph for querying on-chain pool data.

  name: Clipper RFQ API
  description: Request-for-Quote swap API for the Clipper DEX. Aggregators retrieve pool state (price feeds, k factor), request
    firm quotes, and sign quotes to obtain the EIP-2098 signature/calldata needed to execute swaps against Clipper pool contracts
    on Ethereum, Polygon, Optimism, Mantle, and Arbitrum. API v2 is served from blade-api.sushi.com with x-api-key authentication;
    API v1 remains at api.clipper.exchange.
