PumpSwap vs Raydium for Solana meme coins: how pump.fun coins trade on ripr

By ripr Editorial Team14 Nov 20267 min read

For a Solana meme coin trader, PumpSwap vs Raydium is not really a choice you make on ripr. The app can trade coins across 13 Solana venue families, with pump.fun's bonding curve, PumpSwap, all four Raydium pool types and its own curve among them, and it routes each trade to the market that coin actually trades in. Whether a given coin is tradable depends on its pool.

The venue name still tells you something worth knowing: which coins turn up there, what the pool charges, and how deep it is. Here is what differs between the two, and how to read it in ripr before you buy.

PumpSwap vs Raydium: what actually differs

PumpSwap and Raydium are both automated market makers on Solana. An automated market maker holds a pool of two tokens instead of an order book, and your swap shifts the balance between them; that balance is the price. Every swap pays the pool's own fee, which goes to whoever supplied the liquidity.

PumpSwap is pump.fun's own market maker, and it is where a pump.fun coin lands when it graduates off the bonding curve. Raydium is the older of the two and runs several kinds of pool: the classic pair pool (AMM v4), the newer CPMM, the concentrated-liquidity CLMM, and LaunchLab for brand-new coins. A coin launched on ripr's own bonding curve graduates into a Raydium CLMM pool, with 95% of the SOL it raised going straight into that pool.

	PumpSwap	Raydium
Pool families	One AMM	AMM v4, CPMM, CLMM, LaunchLab
Typical pool fee on a swap	0.30%	0.25%
Where its meme coins arrive from	pump.fun graduations	LaunchLab launches, plus coins graduating from other curves

The venues set those pool fees themselves, they can change them, and some pools sit on a different tier. Before you confirm a trade, ripr's trade sheet on iOS and Android lists the network fee, any router fee and the refundable account deposit, and the help centre sets out what fees are charged during trading.

How to see whether a coin trades on PumpSwap or Raydium

ripr's Explore screener filters coins by trading venue, so you can list a venue's coins directly. The venue list names each pool type separately — PumpSwap · AMM, Raydium · AMM v4, Raydium · CLMM, Raydium · CPMM and Raydium · LaunchLab — alongside a launchpad filter and range filters for market cap, liquidity and age. Put a floor under liquidity and the thinnest pools on that venue drop out of the list.

The screener has one guard rail worth knowing. Sort by market cap and it hides coins under $5,000 of liquidity or with fewer than 100 holders, unless you set those limits yourself.

For a single coin, the stage is on its own page. Open the coin, go to the About section and read the Bonding Curve progress, which updates live as the coin trades. At 100% the coin has graduated and trades in a pool rather than on a curve, and the help centre explains what "about to graduate" and "graduated" mean for users.

Why the pool matters more than the PumpSwap or Raydium label

A venue name tells you nothing about how much size a pool can absorb; the pool's own depth does, which is why ripr's screener lets you put a floor under liquidity before you open a single coin.

Take two coins out of ripr's own market data. Catecoin's main market is a PumpSwap pool holding roughly $2.6 million of liquidity, while POPCAT, a much older meme coin, trades mainly in a Raydium AMM v4 pool with roughly $3.8 million. Two different venues, pools in the same bracket.

Holder concentration splits those two far more sharply than the venue does. On POPCAT, the top ten wallets hold about half the supply ripr sees held in wallets, with pools and vaults left out; on Catecoin the same measure sits closer to a sixth. That is not a verdict on either coin. It is a number that should change your size.

A coin can also have pools on more than one Solana venue at once. ripr picks one main market per coin and reads that coin's figures from it.

The test that settles it is your own order. Larger buys and sells move the quoted price more, and most of all in a thin pool, so start smaller in a market you don't know yet. The help centre's note on how your buy size and sell size affect price is the short version.

How to trade a PumpSwap or Raydium coin on ripr

On ripr, trading a coin on either venue is the same four moves.

Find the coin by its contract address. A contract address is the unique mint address that identifies a coin on Solana, and it is the one part nobody can fake. ripr's search takes a name, a ticker or a full address pasted in.
Read the holders. Each coin page shows how much of the supply the top 10 and top 50 holders and the creator hold, with pools and vaults left out. A crowded top ten is a reason to trade smaller.
Set a slippage you understand. Slippage is the largest price change you will accept while the trade executes. ripr's Auto slippage works that limit out from how far the coin moved in the last five minutes, between 3% and 15%, and you can set your own instead.
Confirm. ripr's server prepares the transaction, the app checks it on your device against the amount and slippage you chose and refuses it if anything differs, and your own wallet signs it.

Because a PumpSwap or Raydium pool is a DEX pool, the transaction carries a minimum-output limit worked out from your slippage, so a fill worse than that limit is rejected on chain. If the price moves while you are deciding, the app asks you to accept the new one before anything is signed.

Keep a little SOL spare while you are at it. Network fees are paid in SOL, and your first buy of any coin opens a token account with a small refundable deposit.

What to check before buying meme coins on either venue

The checks are the same whichever venue the pool sits in, because they are about the coin rather than the market it trades in, and the coin page puts them in front of you.

ripr runs rule-based checks for known rug patterns before a buy and shows what they turn up: a creator holding unlocked liquidity, liquidity that has already been pulled, a launch that looks coordinated. On iOS and Android the coin page also flags coins that are under review, low on liquidity, still being checked or showing paused prices. The app never labels a coin safe, and no warning showing is not the same thing as a clean coin.

Then the habits that cost nothing:

Size each trade so a total loss would be survivable. Meme coins reach zero often.
Paste the full contract address rather than trusting a ticker. Names and logos get copied.
Keep SOL in the wallet for fees, so a trade doesn't stall on the last step.
Ignore DMs offering to rescue your wallet or hand you an airdrop. No honest app asks for your recovery phrase.

Frequently asked questions

Is PumpSwap better than Raydium for Solana meme coins?

Neither venue wins in the abstract. PumpSwap and Raydium are both automated market makers, and what decides your fill is the depth of the single pool your coin trades in, not the name above it. On ripr you don't pick between the two, because each trade is routed to the market that coin trades in.

Do pump.fun coins graduate to PumpSwap or Raydium?

A pump.fun coin graduates off its bonding curve into a PumpSwap pool, PumpSwap being pump.fun's own market maker. Coins launched on ripr's own bonding curve graduate into a Raydium CLMM pool instead, and both kinds of pool are tradable in the app.

Does the trading venue change the price I get?

The venue does not set the price; the pool does. A pool's fee and its depth both turn up in your fill, and a large order in a thin pool moves the quoted price further than the same order in a deep one. On ripr the quote is for the pool your coin actually trades in, and if the price moves before you sign, the app asks you to accept the new one.

What is the difference between a Raydium AMM and a CLMM pool?

A Raydium AMM v4 pool spreads its liquidity across every price the pair could reach, while a CLMM pool concentrates it inside a price range the liquidity provider picks. ripr can trade coins in both, along with Raydium's CPMM and LaunchLab pools and PumpSwap's AMM.

Where to start on ripr

PumpSwap vs Raydium comes down to the depth of the pool you are buying into. Open Explore, filter by venue when you want one market's coins in a single list, put a floor under liquidity, and read the warnings and the holder split before you read the price. If the coin you are after sits in a Raydium pool, the full walkthrough is in our post on how to trade on Raydium, step by step on ripr.
