Slippage on Robinhood Chain, Explained
Slippage on Robinhood Chain (chain ID 4663) is a client-side setting that tells the router the worst execution price you are willing to accept, expressed as a percentage away from the quoted price. If the pool moves against you by more than that value between the moment you sign and the moment the block includes your transaction, the swap reverts instead of filling at a worse price.
Slippage is not a fee, not a prediction of your fill, and not the same thing as price impact. It is a safety cap on the gap between what the preview showed and what actually executes — and picking a value that is either too tight or too wide is one of the most common causes of failed or badly-filled swaps on chain 4663.

What the number actually controls
A 1% slippage tolerance means the router will let the trade execute at up to 1% worse than the quoted output; anything worse reverts. It does not promise you a fill, and it does not compensate you if the fill is a hair better than the cap — it just draws a line the pool cannot cross without cancelling the trade.
Picking a value against real pools
Deep, stable pools on chain 4663 usually execute at very tight settings (a fraction of a percent). Thin memecoin pools may require several percent just to execute at any size. Start conservative, widen only until the trade routes, and record what worked for that pool so the next trade starts from evidence.
Limitations
Slippage does not cap price impact caused by your own order size. It also does not protect against a contract that taxes the trade after preview or a pool that is drained between signing and inclusion. Treat it as one control, not a full risk cover.
Frequently asked questions
Is a higher slippage always better? No. A wider tolerance increases the chance of a fill but exposes you to a worse execution price and to sandwich-style MEV. Pick the tightest setting that still routes for your size on that specific pool. What does 'slippage too low' mean when the swap reverts? The pool moved further away from the quoted price than your tolerance allowed before your transaction was included, so the router aborted the trade instead of executing at the worse price. Is slippage the same as price impact? No. Price impact measures how far your trade itself pushes the pool price. Slippage is a separate ceiling on how far the price is allowed to move between preview and execution.
