Raydium

Type: DEX

Raydium is a leading DEX on Solana, operating as both an AMM and an order book-integrated exchange. Unlike pure AMMs, Raydium pools share liquidity with OpenBook (formerly Serum), Solana's central limit order book, giving LPs exposure to both passive AMM and active order book flow.

Market Microstructure Analysis​

Raydium's hybrid design bridges AMM and CLOB liquidity: when LPs deposit into a Raydium pool, their liquidity is also made available on OpenBook's order book as resting limit orders at the AMM-derived price. This means AMM liquidity can interact with limit orders placed by CLOB traders, and vice versa — a trader submitting a market order on OpenBook can be filled against Raydium's AMM liquidity when CLOB resting orders are insufficient. This design improves capital efficiency by letting the same LP capital serve two venues simultaneously. Solana's low block times (~400ms) and low transaction costs make this hybrid model practical (the cost of converting AMM positions to CLOB orders is minimal) where it would be prohibitively gas-expensive on Ethereum. Raydium uses a CPMM formula for standard pools and a Stableswap variant for pegged asset pools. Like PancakeSwap, Raydium includes auxiliary DeFi products (yield farming, an accelerator, token launchpad) that drive demand for its pools and RAY token.

Key Innovations​

  • AMM-CLOB hybrid: LP capital shared between AMM pools and OpenBook order book
  • Solana-native design: leverages low block times and gas costs for hybrid model
  • OpenBook integration: AMM liquidity as resting CLOB limit orders
  • Multi-product ecosystem: DEX, launchpad, and yield farming
