Slippage
Slippage is the difference between the price you were quoted and the price your trade actually fills at. Your slippage setting is the worst outcome you will accept. If the market moves further than that before your trade lands, the transaction fails instead of filling.
Why fills differ from quotes
Jupiter's developer docs say slippage depends on the volatility of the pair, your trade size relative to pool liquidity, and the time between quoting and execution. On fast-moving memecoins, other trades often land between your quote and your transaction, and each one moves the price.
What the setting actually does
GMGN's docs define the setting as the maximum acceptable deviation in the amount of tokens you receive. With 30% slippage on a buy, the trade succeeds if you get at least 70% of the quoted tokens and fails if you would get less. Pump.fun's program enforces the same idea on its curve: a buy names a maximum SOL cost and a sell names a minimum SOL output.
Jupiter's Router uses a fixed 0.5% slippage by default. Its Real-Time Slippage Estimator picks a tolerance per swap from token category, historical slippage and live failure rates, trying to balance trade success against price protection.
The trade-off
A low setting protects your price but makes more transactions fail when the market is moving. A high setting makes fills more likely but lets you buy at a much worse price. GMGN's docs recommend 30% to 35% for automatic orders and 50% or more for new and popular tokens. That shows how wide memecoin settings get.
GMGN's docs also explain that sandwich bots can trade just before your order, push the price up, and leave you with fewer tokens. A wide slippage setting is what gives them room. Anti-MEV or protected sending options exist for this reason.
What it means before you trade
Treat slippage as a price limit, not a fee. Set it as tight as the market allows, widen it only when you accept a worse fill, and keep it separate in your head from price impact. Price impact is the predictable move your own trade causes. Slippage covers what everyone else does in the meantime.
