Robinhood Chain slippage
Slippage is the difference between the price a Robinhood Chain swap quotes at signature time and the price it actually fills at when the transaction is executed on chain 4663. Because AMM pools reprice with every trade, some slippage is normal; the "slippage tolerance" you set is the maximum move you will accept before the transaction reverts.
Setting slippage too tight causes swaps to fail (and still cost gas); setting it too loose lets the swap fill at a much worse price than expected, including MEV-driven sandwich fills. It is a decision the trader has to make consciously for each pool.

How it is measured
slippage_% = (executed_price − quoted_price) / quoted_price. Wallets and routers express it as a tolerance, e.g., 1% or 5%; a swap that would fill outside the tolerance reverts, protecting the trader from arbitrarily bad fills.
How to interpret it
Deep pools with small trade sizes need very little slippage tolerance. Shallow pools, memecoins with transfer taxes, and large trades all need more. If a token requires 20%+ tolerance to fill at all, that is a signal about pool depth, not a green light to trade.
Caveats
Slippage does not guarantee a good price — it only bounds the worst acceptable one. It cannot fully prevent MEV; it only makes extreme sandwich attacks less profitable. On tax-on-transfer tokens, the tax counts as slippage from the router's point of view.
Concrete example
A trader tries to swap 1 ETH for a memecoin on chain 4663 with 1% slippage. The wallet estimates 100,000 tokens; the transaction reverts because a competing trade repriced the pool. Retrying at 3% slippage fills at 97,500 tokens — inside tolerance but 2.5% worse than the original quote.
Frequently asked questions
What is a safe slippage on Robinhood Chain? There is no single safe number. Deep pools handle 0.5–1%; small memecoin pools may require several percent. Match tolerance to pool depth and trade size, not to a rule of thumb. Does slippage tolerance protect me from a scam token? No. Slippage bounds price movement; it does not check whether the token contract lets you sell or takes an outbound tax. Read the contract for that. Why did my swap fail even though I set slippage? Either the pool moved further than your tolerance in the block your transaction landed, or gas ran out. The transaction still cost gas because it was included on chain 4663 before reverting.
