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.

Nash Exchange, formerly knows as NEX, is a decentralized exchange. Nash's decentralized exchange is powered by an off-chain matching engine that allows users to trade a variety of digital assets across several blockchains. The exchange's NEX token, gives holders the opportunity to stake tokens to earn a portion of the fees generated.

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.
