Overview
The Acala DeX protocol is inspired by Uniswap, but built as a runtime module as part of the Acala Substrate chain to serve the aUSD community. Each liquidity pool contains a balance of two tokens, and the exchange rate is simply the amount of one token divides that of the other. Users enjoys instant token swap without the need for an order book, whereas liquidity provider could supply liquidity of the two tokens in a pool to earn a fee.
Refer to Deposit & Earn for liquidity provider returns.
