Multi

Multi is a trading aggregator on Solana that consolidates quotes from Jupiter, Raydium, Orca and Meteora into one interface, letting a user fill at the best route in a single transaction. It also ships a Swap API that requires no key application and charges 0.5% of volume, deducted during on-chain settlement.

On the mechanism side, the router pulls depth and prices from every pool in parallel while quoting, then splits large orders across multiple pools through multi-hop routing to reduce single-pool slippage; each returned route is simulated before execution and falls back to an alternate pool when a leg fails. Its users are active Solana traders and front-end teams that need embedded swap capability. In the first half of 2026 the team merged the integration guide and the route status page into one entry point and completed an error-code reference for failed trades.
