Hi there! 

We’re Primex. Primex is the new prime brokerage liquidity protocol for DEX-agnostic cross-margin trading with trader scoring mechanisms. 

With Primex, lenders provide liquidity to pools where traders then use it for leveraged trading. This gives lenders the opportunity to earn higher yields compared to lending protocols, as the interest is generated from margin fees and profits of successful trades.

The project will be launched on Moonbeam and a few ETH L2s.. Primex.finance is backed by some of the top VCs in the space, including Stratos Technologies, Coinfund, Hypersphere, Wintermute, GSR and others.
