Raydium is the highest-volume DEX on Solana by trading volume, processing hundreds of millions of dollars daily — driven primarily by memecoin trading activity. Raydium's unique position as the primary liquidity destination for tokens graduating from Pump.fun, Solana's dominant token launch platform, makes it the default trading venue for thousands of newly created tokens.
CPMM and CLMM
Raydium operates two pool types: CPMM (Constant Product Market Maker, the classic xy=k model) for new or speculative tokens, and CLMM (Concentrated Liquidity Market Maker, similar to Uniswap v3) for established pairs. New tokens from Pump.fun automatically create CPMM pools on Raydium when they graduate (reach a $69K market cap threshold).
Pump.fun Integration
Raydium's explosive growth in 2024 is largely attributable to Pump.fun — a platform where anyone can create a Solana memecoin in seconds for minimal cost. When a Pump.fun token reaches its graduation threshold, it automatically migrates to Raydium with an initial liquidity pool. On peak days, thousands of new tokens launch this pipeline, generating enormous trading fees.
This creates a unique arbitrage dynamic: newly launched tokens on Raydium often have wide spreads and high volatility in the first minutes, with prices sometimes moving 10–100× before stabilizing. Bots specifically target these launches for MEV and arbitrage.
OpenBook Integration
Unlike most AMMs, Raydium's original architecture integrated with OpenBook (formerly Serum), Solana's central limit order book. AMM LPs provided depth to the order book as well as the AMM pools, theoretically improving price discovery. This hybrid model has become less prominent as CLMMs have grown.
RAY Token
RAY token earns protocol fees from all Raydium pools. Stakers receive a share of swap fees and farm rewards. Raydium has implemented fee buybacks to support RAY value proportional to protocol revenue growth.
