Ren, previously known as the Republic Protocol, is a decentralized dark pool exchange protocol; designed to support large volume trades, without effecting the prices of the assets being traded. The blockchain-based, dark pool protocol has built in privacy mechanisms and is provably fair. It uses secure multi-party computation (sMPC), and a network of Darknodes, to match orders without exposing their volume or price. Their private order book will also enable cross-chain trades of tokenized assets. The Singapore based company is also developing RenX, a decentralized dark pool exchange, built with the Republic Protocol. REN is the network's utility token. It provides security to the network, and is staked to enable the operation of a Darknode in the network.

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.
