All the liquidity that matters on Solana, and you decide which parts of it a campaign uses. The selectable platforms are the aggregators Jupiter, Titan and DFlow; the AMMs and concentrated-liquidity venues Raydium, Orca, Meteora, Invariant, Crema, Byreal, Cropper, Aldrin, FluxBeam, Saros, GooseFX, GuacSwap, Penguin, Step, BonkSwap and Stabble; the order books Phoenix, OpenBook and Drift; the market-maker venues Lifinity, SolFi, Tessera V, HumidiFi, Obric and WOOFi; the stableswaps Saber, Mercurial and Perena; Sanctum for LST pairs; and the launchpads Pump.fun with PumpSwap, Bonk.fun, Raydium LaunchLab, Jupiter Studio, Believe, Bags, Boop, Heaven, Daos.fun and Vector. Choosing the launchpad is a required step after the token is verified, and it is detected and preselected where possible. Exchange routing is not a manual choice: the router uses every supported venue your token actually has a pool on, weighted by live depth, and skips the rest.
