This article explains liquidity pools on the Stellar network, introduced in Protocol 18. It covers how constant product price curves work, how they integrate with path payments to improve trading efficiency, and their potential for future evolution.
The article provides a comprehensive technical explanation of liquidity pools as a new feature in Stellar Protocol 18. It begins by explaining the problem liquidity pools solve—enabling asset exchanges without relying solely on orderbook orders. The article then details how constant product price curves work mathematically, using the formula L=XY to demonstrate how reserves adjust to maintain liquidity. It explains the 0.3% trading fee that incentivizes liquidity providers and allows them to earn returns. The article then explores how liquidity pools integrate seamlessly with Stellar's existing path payment mechanism, showing through examples how pools expand trading possibilities and improve exchange rates compared to orderbook-only trading. Finally, it discusses the native protocol-level integration as a competitive advantage and hints at future enhancements like dynamic fees and multi-asset pools.
