The curve

Constant product.x · y = k.

Prices come from the pool, not an order book. The product of the two reserves stays constant, so trading one token in pushes the other's price along a smooth curve.

Invariant

x · y = k

Reserves multiply to a constant. Every trade slides along the curve, setting price automatically.

Fee

0.3% to LPs

A fee is taken on every swap and left in the pool, accruing to liquidity providers over time.

Pair

WETH / USDC

Two ERC-20 reserves. Deposit both to mint LP shares; burn shares to redeem your slice.
