Primex is the cross-chain prime brokerage liquidity protocol for cross-DEX margin trading with trader scoring mechanisms. In Primex, lenders provide liquidity to pools where traders can use it for leveraged trading in cross-DEX environments, while lenders then have an opportunity to earn high yields; their interest is generated from margin fees and profits on successful trades. Lenders have the flexibility to manage their risks and return by providing liquidity to a variety of risk buckets, subsets of liquidity pools that regulate trader risk strategies.
