DFlow

DFlow is trade-execution infrastructure for Solana, built around order flow segmentation: separating "non-toxic" order flow, typically retail swaps, from "toxic" flow such as bots and MEV activity, so the two can be priced differently.

The protocol runs decentralized order flow auctions. Market makers bid on Order Flow Contracts that give them the right to fill non-toxic flow, and the auction proceeds are rebated to the source of that flow, such as a wallet or application. A network of endorsers rates the toxicity of order flow, and market makers are held to fill-price rules that must stay within a governable threshold of the best available price.

On top of this, DFlow offers a Spot Trading API for swapping SPL tokens. Applications request trade parameters and receive fully constructed transactions to sign and submit. It re-optimizes the route at execution time as liquidity shifts, streams quote and book data across ten levels of depth, and supports gasless swaps where the application sponsors fees, plus composable transactions that bundle a trade with other instructions. An alternative intent-based endpoint adds sandwich protection at the cost of composability. DFlow charges no protocol fees on spot trades; applications set their own.
