Jupiter

Jupiter aggregates liquidity from every Solana DEX to automatically find the best swap rates. Founded by 'Meow' and launched in 2021, Jupiter has become the default swap interface for Solana users, processing billions in daily volume. With zero platform fees, users only pay the underlying DEX fees. Added features include limit orders, DCA automation, perpetual futures trading, and cross-chain bridge aggregation. The JUP token airdrop in January 2024 was one of the largest in crypto history, distributing tokens to over 1 million wallets.

Jupiter routes your swap through multiple Solana DEXs (Raydium, Orca, Meteora, etc.) to find the optimal path for your trade. When you request a swap, Jupiter's routing algorithm analyzes all available liquidity sources, considering factors like price, slippage, and fees. It often splits trades across multiple DEXs or routes through intermediate tokens to achieve better rates than any single DEX. Jupiter itself charges no fees—you only pay the underlying DEX fees and Solana's minimal transaction costs (~$0.001). The platform also offers limit orders executed by keeper bots, DCA for automated regular purchases, and perpetual trading through an integrated perps protocol.
