At a glance
Uniswap V2 ↗ and Raydium ↗ are two DEXs that dominate meme and long-tail token trading. Uniswap V2 is the original constant-product AMM, deployed on 6 chains with $1.2B TVL (as of 2026-05-28). Raydium is a Solana-only venue offering both constant-product and concentrated-liquidity pools, holding $1.5B TVL. Uniswap V2 suits users who need cross-chain access and a battle-tested design; Raydium is the go-to for Solana's meme ecosystem, tightly integrated with pump.fun.
Key differences
Chain support. Uniswap V2 runs on Ethereum, Arbitrum, Optimism, Polygon, Base, and BNB. Raydium is exclusive to Solana. The multi-chain footprint gives Uniswap V2 broader reach for non-Solana assets.
TVL. Raydium holds $1.5B versus Uniswap V2's $1.2B. Raydium's concentration on one chain often translates to deeper pools for Solana-native tokens.
Pool models. Uniswap V2 uses the classic x*y=k constant-product model. Raydium offers both constant-product and CLMM pools, giving LPs more capital efficiency on the latter.
Meme token focus. Both are major venues for meme coins. Uniswap V2 is described as “heavily used for long-tail and meme tokens” per DeFi Intel data. Raydium’s “deep integration with pump.fun and meme markets” gives it a direct pipeline from token launches to liquidity, making it the natural home for Solana meme trading.
Governance. Uniswap V2 is governed by the Uniswap DAO using the UNI token. Raydium is governed by the Raydium DAO with the RAY token. Both are community-controlled.
Security and track record
Uniswap V2 has been live since 2020 and was audited by dapp.org and Trail of Bits. No incidents are recorded in our data. Its code is widely forked and has withstood the test of time. Raydium launched in 2021, audited by Kudelski and MadShield, with no recorded incidents. Uniswap V2’s extra year in production and its role as an industry template give it a marginal edge in battle-testing, but Raydium’s Solana-specific risks (e.g., network congestion) are distinct and not audited against in the same way.
Fees and costs
Exact fee structures are not disclosed in our dataset. Uniswap V2 typically charges a flat 0.30% swap fee; consult the Uniswap docs for current rates. Raydium offers multiple fee tiers on its CLMM pools and a standard tier on its constant-product pools; see the Raydium documentation for specifics. On-chain gas costs differ materially: Uniswap V2 transactions pay L1 or L2 fees depending on the chain, while Raydium incurs Solana’s low per-transaction cost.
Which should you choose
Pick Uniswap V2 if you:
- Need access to Ethereum and its L2s.
- Trade tokens not on Solana.
- Prefer the simplicity and battle-tested nature of a constant-product pool.
Pick Raydium if you:
- Trade Solana-native meme coins and want direct pump.fun integration.
- Value fast, cheap transactions on Solana.
- Want the option of capital-efficient CLMM pools.
Verdict
No universal winner. Uniswap V2 is the better fit for multi-chain users and those who trade beyond Solana’s ecosystem. Raydium is the superior choice for Solana meme trading thanks to its pump.fun integration and concentrated-liquidity options. Your chain preference and token focus should drive the decision. Both DEXs are audited and incident-free as of this writing.
