What is slippage? A beginner's guide to the number on every ripr trade

Slippage is the gap between the price you are quoted and the price your trade actually gets. On ripr it shows up as one setting on the trade screen — your max slippage — and the app fills it in for you, sized from how much the coin in front of you has been moving. Here is what that number means, why the gap exists at all, and what ripr does with it when the market moves while you are still tapping.

Slippage, in plain words

When you type an amount into ripr's buy sheet, the app quotes you an estimate: this much SOL buys roughly that many tokens. Between that estimate and the moment your trade lands on Solana, other people are buying and selling the same coin. If the price has moved by the time your trade goes through, you end up with a slightly different number of tokens than the estimate showed. That difference is slippage. If you have ever ended up with a few fewer tokens than the estimate showed, this is almost always why.

Your max slippage is the ceiling you put on it — the biggest price change you are willing to accept on the way through. ripr's help centre says it in one line: slippage is the maximum price change you allow during execution. That really is the whole idea.

The ceiling cuts both ways. A tight one keeps you close to the quoted price, but your trade is more likely to stop instead of filling when the coin is moving fast. A looser one fills where a tight one would stop, and lets the price drift further from the quote first. That is why it is a setting rather than a fixed number.

Why the price moves between the quote and the fill

Solana settles trades in well under a second, and in that window plenty of other buys and sells can land on an active meme coin. ripr's prices, charts and trade feeds update live over a streaming connection rather than waiting for you to refresh the page, so what you are reading keeps up with the market. The one price no chart can show you is the one a second from now, and that is exactly where slippage lives.

Size matters as much as speed. New and small coins usually trade against a light pool of liquidity, so each trade shifts the price more than you would expect — far more than the same trade would move a large, deep market.

The gap between one coin and the next is wider than most beginners expect. In ripr's own market data, one busy coin had moved about 2% over the previous five minutes: an ordinary five minutes. Another, with only a few thousand dollars of liquidity behind it, had moved more than 40% in the same five minutes. On the second coin, a 1% ceiling would stop almost every trade you tried to place.

If the estimate changes while you are looking at it, that is the same effect at work. Quotes move as other people trade, and ripr's help centre treats a changed quote as normal market behaviour rather than a bug.

Where you meet slippage on ripr: your maximum

ripr handles the setting for you unless you take it over. Auto slippage is on by default, and it sets your maximum from how much that particular coin moved in the last five minutes, between 3% and 15%. A quiet coin gets a tight ceiling. A coin that has been swinging gets a wider one, because a tight ceiling would stop nearly every trade you tried on it.

You can also set the number yourself. The web trade panel offers 1%, 3%, 5% and 10%; the iOS and Android trade settings offer 0.5%, 1%, 3%, 5% and 10%. Which of those to pick is a question in its own right. If you are new, the simplest answer is the one ripr's help centre gives: start with Auto and leave it there.

One point is worth being blunt about, because it trips up almost every beginner. Your max slippage is not an amount you pay. It is a limit you set. Set it to 10% and you are not handing over 10% of anything — you are saying you would still accept the trade if the price moved that far. If the price sits still, you get the quote you saw.

What happens when the price moves past your maximum

Your ceiling earns its keep in the moment the market runs away from you. If the price moves beyond your max slippage, ripr stops the trade instead of filling it at the worse price, and it tells you so in plain words: the price moved more than your max slippage, so nothing was bought, only the network fee was spent, and you can raise max slippage or try again.

This is one of the most common reasons a beginner's trade "fails" on a fast-moving coin. Nothing is broken. Your limit did exactly the job you set it to do, and the trade stopped rather than filling somewhere you had not agreed to. The usual next move is to reopen the trade on a fresh quote, and on a coin running that hard, with a smaller amount.

ripr puts one more check in front of all of this. Its execution layer prepares your transaction on a server. Before anything is signed, the app checks that prepared transaction on your device against the amount, slippage and fee limits you chose, and refuses it if anything differs. Then your own wallet signs it. That check is about the transaction matching what you asked for; it says nothing about whether the coin itself is worth buying.

Slippage is not a fee, and not price impact

Three numbers get mixed up here, so it is worth separating them.

• Slippage is the price movement you allow between quote and fill. You set the ceiling, and setting it costs you nothing.
• Price impact is the part of the move your own order causes by taking up the liquidity sitting at each price. Bigger order and thinner pool mean more impact, and ripr's help centre has a short page on how your buy and sell size affects the price.
• Fees are amounts that are actually charged. On iOS and Android, ripr's trade sheet lists the network fee, any router fee and the refundable account deposit before you confirm.

Keep a little SOL spare in your ripr wallet for the network fee while you are at it. Every Solana transaction needs it, including the ones that stop at your slippage limit.

Habits that keep slippage from surprising you

A few beginner habits make the number far less mysterious.

1. Look at how the coin has been moving before you size the trade. ripr's web charts run eight timeframes from one second to one day, and the iOS and Android charts run from tick up to one day with your entry line and your trade markers on them. Five minutes of chart tells you roughly what sort of slippage to expect.
2. Start small on a coin you have not traded before. A small first buy costs little to learn from, and a smaller order takes less of the available liquidity, so it moves the price less.
3. Read the warnings before the numbers. Before you buy, ripr shows warnings for known rug patterns — a creator holding unlocked liquidity, liquidity that has already been pulled, a coordinated launch — on the coin page and again in the buy flow. The app puts the right attitude in its own words: "These are the risks we can check for. Not seeing one never means a coin is safe." Our guide to spotting a risky meme coin walks those checks properly.
4. Treat thin markets with respect. ripr's iOS and Android coin pages flag coins with low liquidity, coins under review and coins whose checks are still running, and they never label a coin safe. Low liquidity is also the condition that makes slippage wide, so that flag is worth reading twice.

The short version

Slippage is just the market moving between your quote and your fill, and your max slippage is how much of that movement you are willing to accept. ripr sizes it for you from the coin's last five minutes, shows you the estimate before you confirm, and stops the trade rather than filling it past your limit.

Next time you open a coin on ripr, glance at the maximum before you tap buy and read it for what it is: a ceiling, not a charge. If you want the rest of the trade walked through from the start, our step-by-step guide to buying a Solana meme coin on ripr covers it, and the help centre's slippage page is the quick reference to keep bookmarked.
