Initially, LDs will be able to vote liquidity be deployed to Uniswap V2, Sushiswap, Balancer, and 0x. We're working on integrating Uniswap V3 and will stay on top of changes that come with Sushiswap's Trident release. Initially, the primary quote asset that assets can be paired with will be ETH (this is subject to change, so stay tuned).
