PumpSwap Dex

Pump.fun is the launchpad. PumpSwap is what happens after. Tokens start on a bonding curve. When they hit graduation (often described around the ~$69K market-cap area, with roughly ~85 SOL of curve liquidity locked into the pool), they migrate onto PumpSwap automatically. That switch used to go to Raydium and cost about 6 SOL. PumpSwap launched around March 2025 and killed that tax. Migration is instant and free, so more SOL stays in the pool on day one.

Under the hood it’s a classic AMM: x * y = k. You swap against a pool of the token plus SOL (or another quote). No order book, no fancy bin liquidity like Meteora. Simple math, fast Solana fills, heavy memecoin flow. Jupiter and other aggregators can route through PumpSwap when the quote wins, so plenty of people trade it without ever opening a PumpSwap UI.

Fees drop after graduation. Bonding-curve trades are expensive (around 1% class fees). PumpSwap commonly runs near 0.25% per swap, with slices for LPs and the protocol. Some schedules also carve out creator revenue sharing so deployers keep earning a cut after launch. Exact splits can change by pool type or market-cap tier, so check the live pool before you size up. The graduation LP mint is typically burned into an incinerator address. That means the starter liquidity is stuck forever. Nobody can yank the initial pool and rug that way. Extra liquidity can still be added later by normal deposits.

Volume can look huge because Solana memecoins never sleep. DefiLlama-style trackers have shown PumpSwap holding hundreds of millions in TVL and very large monthly DEX volume at peak seasons. That does not mean the tokens are good. Most Pump.fun graduates dump hard. Bots snipe graduations. Thin books and toxic flow are normal. Smart-contract and Solana network risk sit on top of that.

Compared with Raydium or Meteora, PumpSwap is narrower. It’s optimized for the Pump.fun lifecycle, not for SOL-USDC market making or concentrated LP strategies. Raydium still matters for broader Solana liquidity. Meteora wins for advanced LP tooling. PumpSwap wins for keeping pump coins in-house with zero migration drama.

Who it’s for: people trading graduated Pump.fun tokens, creators who want post-graduation fee share, and anyone following Solana meme flow. Who should skip it: long-term investors, beginners who think a graduation badge means safety, and users who need regulated fiat ramps or customer support.

STRENGTHS

- Seamless handoff from Pump.fun bonding curve to open-market trading, no Raydium migration fee

- Starter LP burn locks initial liquidity so classic “pull the pool” rugs are harder on graduation

- Lower swap fees than the bonding-curve phase (often around 0.25% vs ~1%)

- Creator revenue sharing on graduated volume (where enabled) keeps incentives after launch

- Aggregators like Jupiter pick it up automatically when pricing is best

- High throughput on Solana meme volume; simple AMM model is easy to understand

WEAKNESSES

- Almost entirely a memecoin casino. Most tokens go to zero or near-zero

- No concentrated liquidity tools. Capital efficiency trails Meteora-style designs

- Graduation and early trading are bot-heavy. Slippage and snipes are common

- Ecosystem risk is tied to Pump.fun. If that funnel slows, PumpSwap volume follows

- Fee details and creator splits can vary by pool. Easy to misread total cost

- Zero hand-holding. Wallet mistakes, scam coins, and Solana congestion are on you
