Segmenting Flow

• Reduce cyclic arbitrage: Reduce arbitrage from cyclic trading e.g. bots that buy from your pool and sell to a competing AMM pool. You can do this by adding a spread for trades involving a competing venue or specific addresses.
• Be more competitive with retail traders: Keep your base spread tight for retail flow (e.g. txns carrying the Phantom/Solflare fee account or the Jupiter Ultra fee accounts) and add spread only on the toxic/arb flow you target with triggers.
