THE Solana DEX aggregator. If you swap anything on Solana, you are going through Jupiter whether you know it or not - basically every Solana wallet and dApp routes through it. Finds the best rate across all Solana DEXes, supports limit orders, DCA (dollar-cost averaging), and perpetual futures. Also launched their own token (JUP) with one of the biggest airdrops in Solana history. The Uniswap of Solana, except arguably even more dominant on its chain.
