//V2
Uniswap v2 pairs
Constant-product pairs with a flat 0.3% fee. The simplest route to read, and often the thinnest.
How a quote is read
getAmountsOut on Router02 for the direct pair, read at one block. The current price comes from the pair's reserves.
What you sign
Your wallet calls Router02 with the fee-on-transfer-safe exact-in function, your minimum and a 20-minute deadline.
What it asks you to allow
ETH in needs none. A token in needs an approval to Router02.

Where the numbers stop
- A token that takes a tax on transfer can pay out less than the quote; your minimum is what protects you.
- Only the direct pair is quoted; routes through a third token come from v3.
