Raydium has emerged as a cornerstone of Solana’s decentralized finance (DeFi) ecosystem, offering advanced liquidity solutions and shaping the future of on-chain trading. As one of the first automated market makers (AMMs) on Solana to integrate with Serum’s order book system, Raydium introduced innovative hybrid mechanics that set it apart in the early days of Solana DeFi. Today, it stands as the dominant decentralized exchange (DEX) on the network, capturing over 60% of Solana’s DEX trading volume.
This article explores Raydium’s evolution, core technology, tokenomics, and pivotal role in powering Solana’s explosive growth—especially during the 2024 meme coin surge driven by platforms like pump.fun.
What Is Raydium?
Raydium is a decentralized exchange (DEX) built on the Solana blockchain, utilizing an automated market maker (AMM) model to enable seamless token swaps and liquidity provisioning. Initially designed as a hybrid AMM that interfaced with Serum’s (now Openbook) order book system, Raydium allowed users to enjoy both AMM-based instant trades and limit-order functionality.
While Raydium has since discontinued its order book integration due to scalability challenges, it has evolved into a robust liquidity hub offering three distinct types of liquidity pools:
- Standard AMM v4 Pools
- Constant Product Market Maker (CPMM) Pools
- Concentrated Liquidity Market Maker (CLMM) Pools
Each pool type offers unique fee structures and capital efficiency benefits, catering to diverse trading and liquidity provision needs across Solana’s growing ecosystem.

The Evolution of Raydium
Early Development: Bridging AMMs and Order Books
Launched in 2021, Raydium pioneered a hybrid AMM model that combined the simplicity of automated market makers with the precision of order book trading via Serum. This integration enabled:
- Real-time liquidity sharing between Raydium’s AMM pools and Serum’s central limit order book.
- Faster trade execution with minimal slippage.
- Permissionless pool creation for any SPL token.
This design allowed users to switch seamlessly between instant swaps and limit orders—all powered by Solana’s high throughput and low transaction fees.
Additionally, Raydium introduced permissionless pools, enabling anyone to create liquidity pools with customizable parameters such as initial price, fee tier, and liquidity amount. This openness fueled rapid adoption and diversified trading opportunities within Solana’s DeFi landscape.
Mid-Term Shifts: Adapting to Market Realities
Following the collapse of FTX and the subsequent fork of Serum into Openbook, Raydium migrated its infrastructure. However, new challenges arose during Solana’s 2023–2024 meme coin boom.
Meme coins—often characterized by extreme volatility and micro-denominated prices (e.g., 10+ decimal places)—exposed limitations in Openbook’s order book system. Providing passive liquidity required pre-placing numerous orders across unpredictable price ranges, which proved inefficient and technically burdensome.
In response, Raydium:
- Discontinued shared liquidity with Openbook.
- Launched Raydium v3, featuring a streamlined interface and reduced pool creation costs.
- Enhanced support for Token-2022, Solana’s upgraded token standard.
These upgrades positioned Raydium to better serve the demands of a rapidly evolving ecosystem dominated by speculative, community-driven tokens.
Recent Growth: The Pump.fun Catalyst
A major turning point came in January 2024 with the launch of pump.fun, a meme coin launchpad that partnered directly with Raydium. The collaboration introduced an automated liquidity mechanism:
- Any meme coin reaching a $69,000 market cap on pump.fun automatically receives a liquidity pool on Raydium.
- $12,000 in initial liquidity is injected and immediately burned, ensuring decentralization and reducing rug-pull risks.
This frictionless process democratized token launches and funneled massive trading volume into Raydium. Despite pump.fun accounting for only 5.2% of total Solana DEX volume, over 85% of successful pump.fun tokens migrate their trading activity to Raydium, making it the de facto marketplace for trending meme assets.
Core Features and Pool Types
Raydium supports multiple AMM models, each optimized for different use cases:
1. Standard AMM v4 Pools
Based on the classic x × y = k invariant formula, these pools cover the full price range (0 to ∞). Originally required a 0.4 SOL fee to create a market ID on Openbook, they were ideal for established tokens seeking broad liquidity coverage.
2. Constant Product Market Maker (CPMM) Pools
Introduced in Raydium v3, CPMM pools operate similarly but offer flexible fee tiers: 0.25%, 1%, 2%, or 4%. They eliminate the need for external market IDs and support Token-2022, making them more accessible and cost-effective for new projects.
3. Concentrated Liquidity Market Maker (CLMM) Pools
A capital-efficient innovation inspired by Uniswap v3, CLMM allows liquidity providers (LPs) to concentrate their funds within specific price ranges. This increases fee earnings per dollar deposited and reduces impermanent loss for stable pairs.
Team and Development Background
Raydium was founded by AlphaRay, an anonymous team lead with a background in algorithmic trading and quantitative finance. Prior to entering crypto in 2017, the core team specialized in commodity trading and high-frequency market-making strategies.
Other key contributors include:
- XRay: CTO and head of development, with 8 years of experience in low-latency trading systems.
