Overview: Why Compare PumpSwap and Raydium?
If you trade Solana meme coins or long‑tail tokens, you will touch both PumpSwap and Raydium sooner or later.
They sit in different parts of the lifecycle:
- Pump.fun → PumpSwap: tokens launch on Pump.fun’s bonding curve and, once they hit a graduation threshold, liquidity is migrated into a PumpSwap AMM pool.(github.com)
- Raydium: a general‑purpose Solana DEX/AMM with multiple pool types (constant‑product AMM v4, CPMM, CLMM, stable pools, farms, LaunchLab, etc.), used by everything from majors to small caps.(github.com)
For a trader, the question isn’t “which is better overall?” but “which DEX is better for this specific trade, time horizon, and token?”
This article focuses on:
- Core design differences (AMM model, routing, pool types)
- Where tokens list and how liquidity gets there
- Fee structures and what they imply for scalping vs swing trading
- Practical trading workflows using both DEXes
Core Mechanics: How PumpSwap and Raydium Actually Work
PumpSwap: Native AMM for Pump.fun Graduations
PumpSwap is Pump.fun’s own AMM on Solana. It’s tightly coupled to the bonding‑curve launchpad:
- Bonding curve first, AMM later: Pump.fun lets anyone create SPL tokens that are instantly tradable on a bonding curve, without seeding an external LP. When a token reaches a defined market cap / liquidity threshold, liquidity from the curve is migrated to an AMM pool.(github.com)
- Previously Raydium, now PumpSwap: earlier generations of Pump.fun migrated to Raydium; in 2025 Pump.fun introduced PumpSwap and new graduates now go to PumpSwap by default.(pumpview.fun)
- Constant‑product AMM: PumpSwap v1 is described as functioning similarly to Raydium v4 / Uniswap v2, i.e. a constant‑product (x*y=k) AMM.(reddit.com)
- Meme‑coin heavy order flow: academic work and on‑chain analyses show Pump.fun dominates Solana meme‑coin launches and volumes, with PumpSwap capturing the post‑graduation AMM trading for those tokens.(en.wikipedia.org)
In practice, PumpSwap is:
- The default first AMM venue for Pump.fun graduates
- Focused on single‑pool per token, meme‑coin style markets
- Optimized for simple swaps and LP rather than complex routing
Raydium: Multi‑Product AMM + Liquidity Hub
Raydium is a broader DeFi protocol on Solana with several components:
- AMM v4 / CPMM pools: standard constant‑product pools for most spot pairs.(github.com)
- CLMM (Concentrated Liquidity Market Maker): Raydium’s Uniswap v3‑style concentrated liquidity AMM where LPs choose price ranges.(github.com)
- Stable / specialized pools: for correlated assets (e.g. stablecoins, LSTs).(github.com)
- Farms & staking: RAY incentives and dual‑reward farms on top of LP positions.(github.com)
- LaunchLab / AcceleRaytor: token launch and IDO‑style infrastructure.(github.com)
Raydium has also:
- Removed OpenBook dependency: its Swap V2 interface no longer relies on orderbook markets, reducing account overhead and simplifying routing.(blockworks.com)
- Upgraded CLMM in 2026: a 2026‑09 program upgrade rebuilt CLMM on newer Solana/Anchor versions and added admin instructions like
CollectExcessLamports, indicating active maintenance and iteration.(github.com)
In practice, Raydium is:
- A routing hub used by aggregators like Jupiter
- Home to multiple pool types per pair (AMM, CLMM, stable)
- A venue where tokens may list via LaunchLab or community‑created pools
Listing & Liquidity: How Tokens End Up on Each DEX
PumpSwap: Automatic Graduations from Pump.fun
For Pump.fun tokens, the typical path is:
- Launch on Pump.fun: token is created, 100% supply is allocated between bonding curve and creator/other allocations per Pump.fun’s configuration.(github.com)
- Bonding‑curve trading: early price discovery happens entirely on the curve. Volume here can be large; research documents over 100M USD in daily bonding‑curve volume at times.(arxiv.org)
- Graduation trigger: once the token hits the configured market cap / liquidity threshold, Pump.fun’s program migrates the curve liquidity into an AMM pool.
- Destination: PumpSwap: since PumpSwap’s launch, graduates now go to PumpSwap instead of Raydium by default.(pumpview.fun)
Implications for traders:
- You don’t choose the initial AMM venue: if it’s a Pump.fun coin, graduation means PumpSwap first.
- Liquidity is concentrated in a single pool at the start; secondary pools on Raydium or Meteora may appear later if someone seeds them.
Raydium: Permissionless Pools + LaunchLab
Tokens can appear on Raydium via:
- Permissionless pool creation: anyone can create an AMM v4 or CPMM pool by paying a one‑time creation fee (0.15 SOL, according to Raydium’s protocol‑fee docs and transparency framework).(docs.raydium.io)
- LaunchLab / AcceleRaytor: curated launches where projects raise capital and bootstrap liquidity through Raydium’s infrastructure.(assets-cms.kraken.com)
- Community or project‑driven CLMM pools: for more efficient markets, especially for higher‑cap tokens.
Implications:
- Non‑Pump.fun tokens almost always list on Raydium (or Meteora, Orca, etc.) first.
- Even for Pump.fun coins, secondary Raydium pools may emerge once the token gains traction.
Fees: What You Actually Pay to Trade
Network Fees (Both)
Both DEXes run on Solana, so you always pay:
- Base transaction fee in lamports
- Optional priority fee (microlamports per CU) depending on congestion
This is independent of the DEX.
PumpSwap Fees
Public analyses of Pump.fun’s economics describe:
- Bonding‑curve fee (e.g. 1%) during the Pump.fun phase
- PumpSwap swap fee (e.g. 0.3%) after graduation, with a portion of PumpSwap revenue shared with token creators under Pump.fun’s “creator revenue sharing” initiative.(blog.syndica.io)
Key points for traders:
- Once on PumpSwap, you pay AMM‑style swap fees per trade, similar in magnitude to Raydium’s typical 0.25–0.3% swap fees (exact splits vary by pool type and config).(docs.raydium.io)
- Part of the fee goes to LPs, part to the protocol / creator sharing, depending on Pump.fun’s current configuration.
Raydium Fees
Raydium’s docs and transparency reports describe:
- Swap fees on AMM v4 / CPMM / CLMM pools, split between LPs and protocol treasury. Exact percentages differ by pool type and configuration, but are in the typical DEX range (~0.25–0.3% headline fee).(docs.raydium.io)
- Pool creation fee of 0.15 SOL for new AMM v4 / CPMM pools.(docs.raydium.io)
For a pure trader (not LP/creator), the main takeaway is:
- Per‑swap fee levels are broadly similar between PumpSwap and Raydium for standard pools.
- Differences matter more in where liquidity is deepest and how routing works, not in raw fee percentage.
Liquidity & Market Structure: What Your Fills Look Like
PumpSwap: Single‑Venue Post‑Graduation Liquidity
Right after graduation:
- All migrated liquidity is in the PumpSwap pool, so that’s where slippage is lowest for that token at that moment.(github.com)
- There is no concentrated liquidity; it’s a simple constant‑product pool.
- Order flow is heavily retail + bots coming from Pump.fun’s user base and sniping infra.(arxiv.org)
Practically:
- For immediate post‑graduation trades (first minutes to hours), PumpSwap usually offers the best depth and lowest slippage because that’s where the initial LP sits.
- As time passes and secondary pools appear elsewhere, you need to check Birdeye / DexScreener to see where volume and liquidity have migrated.
Raydium: Multiple Pools, Routing, and CLMM
Raydium’s liquidity picture is more complex:
- A token might have both an AMM v4 pool and a CLMM pool, each with different depth and fee tiers.(github.com)
- Raydium is integrated into aggregators like Jupiter, which can route across Raydium, Orca, Meteora, PumpSwap, etc.
- For majors and mid‑caps, CLMM pools can have much better price impact than simple AMMs because liquidity is concentrated around the current price.(github.com)
Practically:
- For larger size trades in established tokens, Raydium (often via Jupiter routing) will usually give better execution than a small PumpSwap pool.
- For newer Pump.fun graduates, Raydium may initially have no or thin liquidity, so execution there can be worse until someone seeds a pool.
UX, Tooling, and Integrations
PumpSwap
- Tight integration with Pump.fun UI: many users interact with PumpSwap via Pump.fun’s interface or embedded swap widgets.
- Simple pair model: typically one main SOL/token or USDC/token pool per meme coin.
- Ecosystem tooling: bots and scanners track the exact moment of graduation and immediately trade on PumpSwap. Reddit and research papers describe low‑latency, program‑level interaction bypassing the UI.(reddit.com)
For traders, this means:
- If you’re sniping graduations, you almost always target PumpSwap first.
- You’ll often rely on specialized scanners (e.g. PumpView, Birdeye, custom Helius/Yellowsone streams) to catch the graduation event and first PumpSwap trades.
Raydium
- Full web UI with swaps, LP, CLMM positions, farms, LaunchLab, etc.(github.com)
- SDKs and APIs (
@raydium-io/raydium-sdk-v2, REST APIs) used by bots and aggregators.(github.com) - Devnet UI for testing strategies and integrations.(blockworks.com)
For traders:
- Raydium is often not your first touchpoint (you may come via Jupiter, Phantom, or DexScreener), but it’s the underlying venue for many routes.
- If you LP or farm, you’ll interact with Raydium’s UI directly.
Practical Trading Workflows: When to Use Which
1. Trading Fresh Pump.fun Graduates
Best venue: PumpSwap (initially)
Workflow:
- Track tokens on Pump.fun’s bonding curve.
- Watch for graduation triggers (on‑chain or via scanners like PumpView, Birdeye, or custom WebSocket streams).(reddit.com)
- Execute first post‑graduation trades on PumpSwap, where migrated liquidity sits.
- Only later check Raydium for secondary pools once the token gains traction.
Why not Raydium first?
- New Pump.fun tokens no longer auto‑migrate to Raydium; they go to PumpSwap. Early Raydium pools, if any, are typically community‑seeded and shallow at the beginning.(pumpview.fun)
2. Swing Trading Established Meme Coins
Likely venue: Depends where liquidity has migrated.
Workflow:
- Use Birdeye / DexScreener to check:
- 24h volume by venue
- Current liquidity and top pools
- Compare PumpSwap vs Raydium pools for that token.
- Route via Jupiter and inspect the route details:
- If it prefers PumpSwap, liquidity is still better there.
- If it prefers Raydium CLMM/AMM, the market has migrated.
Over time, successful Pump.fun coins often see:
- Additional Raydium pools (sometimes CLMM) created by the community or the project team.
- Liquidity and volume spread across venues, making aggregator routing more important.
3. Larger Size Trades in Non‑Pump.fun Tokens
Best venue: Raydium (often via Jupiter)
For tokens that never touched Pump.fun (e.g. serious DeFi protocols, LSTs, majors):
- PumpSwap is usually irrelevant; there may be no pool at all.
- Raydium’s CLMM + AMM + stable pools and integration into aggregators make it the natural venue for size.
Workflow:
- Use Jupiter or your preferred router.
- Check route composition; Raydium is often a major leg.
- If you LP, consider CLMM positions on Raydium for better capital efficiency.(github.com)
Risk & Market‑Structure Considerations
PumpSwap‑Specific Considerations
- Reflexivity around graduation: research and community reports note that many Pump.fun tokens see heavy profit‑taking right after graduation when they hit the AMM pool, causing sharp drawdowns.(reddit.com)
- Bot‑heavy environment: academic work documents coordinated sniper cohorts and automated strategies around Pump.fun launches, which naturally extend into PumpSwap graduations.(arxiv.org)
For traders, this means:
- Be cautious with market buys right after graduation; slippage and volatility can be extreme.
- If you’re not latency‑competitive, consider waiting for post‑graduation stabilization or trading later on Raydium once liquidity fragments.
Raydium‑Specific Considerations
- Multiple pool types: you must know whether you’re trading against an AMM, CLMM, or stable pool; price impact differs.
- Pool quality variance: permissionless pools mean anyone can create shallow or malicious pairs. Raydium has a token transparency framework, but it doesn’t eliminate risk.(impressive-horses-5641a8b530.media.strapiapp.com)
For traders:
- Always verify token mint and pool addresses via Solscan or similar explorers.
- Prefer pools with verified mints, higher TVL, and consistent volume.
Summary: How to Decide Between PumpSwap and Raydium
You can think of it like this:
- PumpSwap is the native post‑bonding‑curve venue for Pump.fun tokens.
- Best for: trading very fresh graduates, participating in early AMM price discovery.
-
Weak for: larger size once liquidity fragments across venues.
-
Raydium is the general‑purpose Solana DEX / liquidity hub.
- Best for: larger trades, non‑Pump.fun tokens, and anything routed via Jupiter.
- Also key for: LP strategies (CLMM, farms) and project launches via LaunchLab.
In practice, a serious Solana trader should:
- Use PumpSwap when:
- A token has just graduated from Pump.fun.
-
Birdeye/DexScreener show PumpSwap as the dominant venue.
-
Use Raydium (often via Jupiter) when:
- Trading established tokens or non‑Pump.fun assets.
-
You care about minimizing price impact on larger orders.
-
Always check:
- Where the deepest pool is right now (Birdeye, DexScreener).
- Route details (Jupiter) instead of assuming one DEX is always better.
Understanding how PumpSwap and Raydium fit into the Solana market structure lets you choose the right venue per trade, rather than treating DEX choice as a brand preference.
