Raydium is a core On-chain Order Book Automated Market Maker (AMM) built on the Solana blockchain. As a vital hub for liquidity within the Solana ecosystem, it not only utilizes its own liquidity pools but also deeply integrates with Serum's (and its subsequent upgraded versions) central order book, allowing traders to enjoy near-centralized exchange speed and shared liquidity.

As of early 2026, Raydium has evolved into a comprehensive DeFi platform: users can not only perform token swaps with extremely low slippage, but also participate in initial offerings of promising new projects on its Launchpad, or earn high yields through liquidity mining. With the explosion of Meme Coins and Decentralized Physical Infrastructure Networks (DePIN) within the Solana ecosystem, Raydium, leveraging its efficient automated market-making algorithms and ultra-low fees, has become the go-to platform for global on-chain players looking to capture opportunities in the Solana market.
