Sei (SEI) And Jupiter (JUP): With New Order‑Book Perps On SEI And Long‑Tail Routing Expanding On JUP, Do SEI And JUP Become A Two‑Chain Trading Stack Or Just Extra Liquidity For Solana And Arbitrum?

The landscape of decentralized trading in the summer of 2026 is rapidly evolving past simple automated market makers (AMMs). Infrastructure specialization is taking center stage. Sei (SEI) is pioneering the implementation of high-throughput, native on-chain order-book perpetuals, challenging the latency limits of traditional non-EVM execution environments. At the same time, Jupiter (JUP) continues to solidify its role as the dominant liquidity router and launchpad ecosystem on Solana, expanding its reach into complex cross-chain routing and long-tail asset optimization.
