Uniswap · Reads onchain state
Reads the amount a Uniswap pool would pay right now for a swap. The pool you pick names its version, and the quote follows it: a V2 pair applies the constant-product formula to its live reserves with the 0.3% fee, while a V3 or V4 pool is simulated through that version's quoter, so concentrated liquidity and tick crossings are priced in. The pools of one pair disagree, so the version and fee tier are named in the list, and the deepest pool is offered first. Reach for it to set a swap floor from a live quote with a slippage haircut, to compare venues before routing, or to gate a trade on a minimum rate with a predicate.
