Off-chain Order Book

For "Off-Chain Orderbook" decentralized exchanges, final trades occur on chain but every order is hosted by a third party called a Relayer. This was the style of many early generation decentralized exchanges built on Bitdollar.



  • Faster order management than On-Chain solutions
  • Less fees involved than On-Chain solutions


  • No full guarantee that a maker order is still active
  • The relayer could front run an order
