Any crypto swap quote is a snapshot of a price that's already moving. By the time a transaction actually confirms on-chain, the market price can have shifted slightly from the moment the quote was generated. Slippage tolerance and "minimum received" exist specifically to manage that gap, and understanding what each one actually controls is the difference between a swap that executes as expected and one that fails or under-delivers.
What slippage tolerance actually sets
Slippage tolerance is the maximum price movement you're willing to accept between the moment you get a quote and the moment the transaction actually settles. Edge Rates' Swap section defaults to an adaptive tolerance, typically around 0.1%, that adjusts automatically based on current market conditions, though it can be set manually if you want tighter or looser control.
Set the tolerance too tight, and a legitimate transaction can fail outright if the price moves even slightly during confirmation, particularly on volatile assets or congested chains. Set it too loose, and you're accepting a wider range of possible execution prices, some of which could be noticeably worse than the quote you saw.
Minimum received: where tolerance becomes a real number
Minimum received is the practical translation of slippage tolerance into an actual guaranteed floor: the worst-case amount of the destination asset you're contractually assured to get, once the platform's visible fee and your chosen slippage tolerance are both factored in. It's the one number in a swap quote that isn't aspirational, everything else is an estimate of what you'll likely get; minimum received is what you're guaranteed not to get less than.
Why this number is the one worth comparing
Different routes and different providers can quote very similar headline rates while differing meaningfully in what they actually guarantee. A route with a slightly lower quoted rate but a tighter, clearly disclosed minimum received can be the better real-world choice over a route with a flashier top-line number but a wider, less transparent gap to its worst-case outcome, a gap that, on some platforms, can run close to 1% without being clearly surfaced upfront.
The takeaway
Treat the headline swap rate as a starting point, not the number to act on. Minimum received is the figure that tells you what you can actually count on, which is exactly why Edge Rates surfaces it directly in the breakdown alongside every route it compares, rather than leaving it buried until after a transaction has already gone through.
