The DODO exchange allows users to trade Crypto through a liquidity protocol that is powered by their Proactive Market Maker (PMM) algorithm. It is an oracle-aided algorithm with an advanced pricing formula that provides contract-fillable liquidity, designed to maximize efficiency and reduced price slippage compared to decentralized exchanges that use an automated market maker (AMM) model. Another relative advantage of the DODO exchange is that it give liquidity providers greater flexibility.

SushiSwap is a decentralized exchange protocol that emerged as a fork of UniSwap. The main difference being the SUSHI token which acts as a governance token and entitles holders to a percentage of the trading fees charged on the network. Both UniSwap and SushiSwap, use an automated market making (AMM) model, where liquidity providers add funds to liquidity pools. Unlike centralized, order book exchanges, token pairs are priced according to an equation in which multiplying the prices of the 2 tokens will always equal a constant.
