Note: Metis is now a standalone, open-source project. For more details, see the Metis docs here.
Metis was Jupiter’s proprietary DEX aggregation engine, launched in 2023. It’s a sophisticated onchain liquidity aggregator designed to find the most efficient trade route for any token pair by factoring in price, slippage, and the difference between quoted and executed prices across multiple DEXes.
In 2025, we released Metis v1.6, which introduced more advanced route splitting and expanded support for a wider range of intermediate tokens.
