Balancer
Balancer is a Decentralized Exchange (DEX) and automated portfolio management of tokens.
The team behind the Balancer Protocol (Balancer Labs) has been in the DeFi space for several years and started Balancer as a research project in early 2018[1]. The company has around 30 employees.
The protocol has its own governance token BAL which has a veModel similar to Curve Finance.
Chains
Balancer is deployed on Ethereum, Polygon, and Arbitrum. It's also deployed to the Kovan, Goerli, and Ropsten testnets.
Additionally, there is a friendly fork on Fantom which was approved by the Balancer DAO[2].
There are no implementations on Tron, or any other networks. Balancer Labs has awarded grants to teams developing on Near and Algorand; however, these are exploratory grants, and does not imply that there are working versions of Balancer Protocol on these systems.
