DFlow is a decentralized order flow marketplace built on the DFlow Protocol's payment-for-order-flow (PFOF) model. It supports order flow from various Layer 1 (L1) blockchains and rollups. On one side, brokerages create, manage, monitor, and analyze order flow auctions, while on the other side, market makers submit bids in these auctions. The winner of each auction gains the exclusive right to fill the underlying orders, streamlining the process for both brokerages and market makers.
