PumpSwap vs Raydium on Solana: Which DEX Should You Trade On?
PumpSwap and Raydium now sit on opposite sides of Solana’s memecoin war. If you trade Solana tokens daily, you don’t need marketing — you need to know where to route your swaps, where liquidity really sits, and what each venue is good or bad at.
This article compares PumpSwap and Raydium from a trader’s perspective, using only what’s publicly documented and observable on-chain.
1. What Each DEX Actually Is
PumpSwap in one paragraph
PumpSwap is Pump.fun’s native AMM DEX on Solana. It was launched in March 2025 specifically to keep Pump.fun’s graduated tokens in-house instead of sending them to Raydium. Tokens that hit the graduation threshold on Pump.fun (around a $69k bonding-curve market cap) now migrate directly to PumpSwap, not Raydium. (phemex.com)
Key points:
- Constant-product AMM (Uniswap v2 / Raydium v4 style) (phemex.com)
- Native destination for Pump.fun graduates; migration is now instant and fee-free for users vs the old 6 SOL migration fee to Raydium. (kucoin.com)
- Optimized for memecoins and fast rotations; later expanded to support non-meme SPL tokens as well. (phemex.com)
Raydium in one paragraph
Raydium is Solana’s oldest and most established DEX and liquidity hub, live since early 2021. It started as a constant-product AMM integrated with Serum order books and has since added standard (CPMM) pools, concentrated liquidity (CLMM) pools, yield farms, and a perpetuals platform. (docs.raydium.io)
Key points:
- Multiple pool types: CPMM (standard), CLMM (concentrated), and routing across them. (docs.raydium.io)
- Still one of the largest liquidity venues on Solana by TVL and swap volume. (file.chainup.com)
- Used for everything from majors (SOL, USDC, WIF) to long-tail tokens and LP yield strategies.
Takeaway: PumpSwap is a specialist memecoin DEX tightly coupled to Pump.fun. Raydium is a general-purpose DEX and liquidity backbone for the broader Solana ecosystem.
2. Fee Structures: What You Actually Pay
PumpSwap fees
Pump.fun’s docs and exchange announcements describe PumpSwap as charging 0.25% per swap on canonical pools, with the split:
- 0.20% → liquidity providers
- 0.05% → protocol / revenue share mechanisms (e.g., creator revenue sharing on some pools) (kucoin.com)
Pump.fun also charges 1% on bonding-curve trades before graduation, but that’s separate from PumpSwap itself. (phemex.com)
Raydium fees
Raydium’s docs show that swap fees depend on pool type:
- Standard CPMM pools: a fixed percentage fee (commonly around the 0.25% range, though exact values can differ by pool).
- CLMM pools: fee tiers per pool (e.g., 0.01%, 0.05%, 0.25% etc.), with a portion going to LPs and a portion to RAY buybacks and protocol incentives. (docs.raydium.io)
On Solana itself, you also pay:
- Base transaction fee in lamports (very small)
- Optional priority fee in microlamports to get confirmed faster during congestion
These network fees apply equally to both PumpSwap and Raydium.
Trader implications:
- For a typical memecoin swap, headline swap fees on PumpSwap and Raydium CPMM pools are in a similar ballpark.
- On Raydium CLMM, you might route through a lower-fee tier (e.g., 0.01%–0.05%) on majors, which can be cheaper than PumpSwap for large size — but only if there’s deep liquidity in that tier.
3. Liquidity & Market Coverage
Where memecoin liquidity lives
Before March 2025, Pump.fun graduates were forced to migrate to Raydium, and Pump.fun-related volume was a major chunk of Raydium’s business. Some reports estimate that around 40%+ of Raydium swap fees came from Pump.fun tokens in the months before PumpSwap launched. (phemex.com)
Once PumpSwap went live and migration switched away from Raydium, several things happened:
- PumpSwap quickly accumulated nine-figure TVL and large daily volumes, becoming one of Solana’s top DeFi protocols. (phemex.com)
- Raydium’s TVL dropped significantly in early 2025 as Pump.fun volume left. (phemex.com)
Today, the default venue for new Pump.fun memecoins after graduation is PumpSwap, not Raydium. If you’re trading the latest microcaps coming off the bonding curve, you’ll generally find the deepest liquidity on PumpSwap first.
Where broader Solana liquidity lives
Raydium still acts as a major liquidity hub for non-Pump.fun tokens:
- Majors: SOL, USDC, USDT, WIF, JUP, RAY, BONK, etc.
- Stable pairs and blue-chip DeFi tokens
- Many project-native pools and CLMM ranges
Reports and dashboards tracking Solana DeFi consistently show Raydium near the top by TVL and swap volume, especially once you include CLMM and yield strategies. (file.chainup.com)
PumpSwap, by contrast, is heavily skewed toward Pump.fun-originated memecoins, even though it does list external tokens and partners. (phemex.com)
Trader implications:
- New Pump.fun graduates / microcaps: liquidity is usually on PumpSwap first.
- Established Solana tokens and majors: deeper and more structured liquidity is often on Raydium, especially in CLMM pools.
4. Pool Types & LP Mechanics
PumpSwap: simple constant-product pools
PumpSwap uses a constant-product AMM (x·y=k) similar to Uniswap v2 and Raydium’s standard pools. (phemex.com)
For traders, that means:
- Price impact is predictable: larger trades move the price along a smooth curve.
- No concentrated ranges; all liquidity is spread across the full price curve.
- Impermanent loss behaves like any other v2-style AMM.
For LPs:
- You provide a token pair at the current price; your position is passive.
- No need to manage ranges, but capital efficiency is lower than CLMM.
Raydium: CPMM + CLMM
Raydium offers:
- Standard CPMM pools (similar to PumpSwap)
- CLMM pools, where LPs choose a price range to concentrate liquidity, improving capital efficiency and fee earnings if the price stays in-range. (docs.raydium.io)
For traders: - Raydium’s routing engine can split or route your swap across CPMM and CLMM pools to get better effective pricing on supported pairs. (stouchentertainment.com)
For LPs:
- CLMM allows higher fee APR per unit of capital if you manage ranges well.
- But you take on range risk — if price leaves your range, you stop earning fees and sit in one asset.
Trader implications:
- If you’re just market-buying or market-selling a memecoin, PumpSwap’s simple CPMM is fine and often the only deep pool.
- For majors and liquid pairs, Raydium’s routing across CPMM + CLMM can give tighter pricing and lower slippage, especially on size.
5. UX, Integrations & Tooling
PumpSwap UX
PumpSwap is tightly integrated into the Pump.fun flow:
- You typically access it via swap.pump.fun or the “Swap” button on Pump.fun. (phemex.com)
- Graduated tokens appear automatically; you don’t need to manually set up pools for most Pump.fun launches. (phemex.com)
This makes it extremely straightforward for:
- Degens rotating through fresh graduates
- Creators who just launched a token and want immediate secondary trading
However, PumpSwap is less feature-rich outside that niche:
- No built-in perps, farms, or complex LP dashboards like Raydium.
- Fewer external integrations historically, though that’s changing as more tools add PumpSwap support.
Raydium UX
Raydium’s interface is more like a full DeFi suite:
- Swap, liquidity, CLMM positions, farming, and sometimes launchpad-style offerings. (docs.raydium.io)
- Strong integration into aggregators like Jupiter, which often route through Raydium pools for best price.
- Many third-party tools (e.g., Birdeye, DexScreener, xick.tools for no-code pool creation) assume Raydium pools as a default for SPL tokens. (reddit.com)
Trader implications:
- If you want one interface for swapping majors, providing CLMM liquidity, and farming, Raydium is more complete.
- If your focus is Pump.fun memecoins and you live in that ecosystem, PumpSwap’s integration is more direct and frictionless.
6. Risk Profile: What Can Go Wrong on Each
Shared risks
Both PumpSwap and Raydium share baseline DEX risks:
- Smart contract risk (bugs, exploits)
- Rug pulls / honeypots at the token level
- MEV and sandwiching on Solana when trading illiquid pairs
Neither DEX can guarantee token quality; both list permissionless SPL tokens.
PumpSwap-specific risks
PumpSwap is dominated by Pump.fun-originated memecoins. Academic and industry analyses of Pump.fun show that the vast majority of launched tokens exhibit rug-pull or abandonment behavior. (arxiv.org)
For traders, that means:
- You are much more likely to be trading short-lived, high-risk tokens on PumpSwap.
- Even if the DEX itself is functioning correctly, token-level risk is extreme.
Raydium-specific risks
Raydium lists:
- A mix of blue-chip and long-tail tokens, including many community-launched coins.
- Historically, some users have struggled with LP migration, UI confusion, or stuck LP positions, particularly during version upgrades and CLMM migrations. (reddit.com)
For traders, the main distinctions are:
- On majors and established tokens, protocol and token risk is generally lower than on fresh Pump.fun graduates.
- On obscure Raydium pools, you still face rug and liquidity risks similar to PumpSwap.
Practical risk takeaway:
- PumpSwap: DEX risk + very high token risk (memecoins by design).
- Raydium: DEX risk + a spectrum of token risk from blue-chip to degen.
7. When to Use PumpSwap vs Raydium (Trader Scenarios)
Scenario 1: Sniping new Pump.fun graduates
- Best venue: PumpSwap
- Why: Graduated Pump.fun tokens now migrate directly to PumpSwap, with no 6 SOL fee and no Raydium dependency. Liquidity and early volume concentrate there first. (phemex.com)
How to approach:
- Track graduation events (via Pump.fun, on-chain logs, or scanners).
- Check slippage and depth on PumpSwap before sizing up.
- Use external charting (Birdeye, DexScreener) to confirm pool addresses and volume.
Scenario 2: Trading majors and established Solana tokens
- Best venue: Often Raydium (or a router that taps Raydium heavily, like Jupiter).
- Why: Deeper liquidity in CLMM and CPMM pools, better routing, and more stable markets for majors. (docs.raydium.io)
How to approach:
- Use Jupiter to auto-route through Raydium and other DEXes for best price.
- If you’re LPing, consider CLMM ranges for majors where volatility is more manageable.
Scenario 3: Providing liquidity
- You want simple, passive LP on a memecoin you launched or hold:
-
PumpSwap’s constant-product pools are simpler; you just deposit both sides and forget (accepting IL risk). (phemex.com)
-
You want to optimize capital efficiency on majors or high-volume pairs:
- Raydium CLMM gives you more control and potentially higher fee APR, but requires active management. (docs.raydium.io)
Scenario 4: Risk-sensitive trading
- If your risk tolerance is low and you’re mostly trading SOL, USDC, WIF, BONK, etc., Raydium (often via Jupiter) is usually the safer default.
- If you’re intentionally hunting high-risk memecoin plays and want to be early to Pump.fun graduates, PumpSwap is unavoidable, but you should treat every position as speculative and short-term.
8. How to Compare Pricing in Real Time
Regardless of which DEX you prefer, you should always verify where the best execution is:
- Use Jupiter to simulate swaps; it will often route across Raydium, Orca, Meteora, and sometimes PumpSwap (depending on integration status and token).
- Check Birdeye or DexScreener for:
- Pool addresses
- 24h volume and liquidity
- Price impact at your intended size
- Confirm token contracts on Solscan or another explorer before swapping, especially on PumpSwap where copycats are common.
This matters because headline fees are only part of the cost — slippage from shallow liquidity can easily dwarf a 0.25% vs 0.20% fee difference.
Conclusion: Use Both, But Know Their Roles
PumpSwap and Raydium are not interchangeable:
- PumpSwap is the native home of Pump.fun graduates and Solana’s memecoin flow. If you trade new launches and microcaps, you’ll be on PumpSwap whether you like it or not.
- Raydium remains a core liquidity hub for majors and DeFi tokens, with advanced LP options (CLMM) and broad integration into Solana’s tooling and routers.
For a practical Solana trading setup:
- Use PumpSwap when you’re specifically targeting Pump.fun graduates or memecoin rotations.
- Use Raydium (often via Jupiter routing) for majors, stable pairs, and more serious size.
- Always cross-check liquidity, slippage, and contract addresses before committing capital.
Understanding the strengths and weaknesses of each venue will help you route orders more intelligently, avoid unnecessary slippage, and align your risk exposure with what each DEX is actually built for.
