As early as 2018, Compound and Aave were the first to introduce permissionless money markets creating pillars for what we know today as DeFi. Yet, after almost four years, little progress has been made for leverage-based DeFi primitives to rival the capital efficiency traditional finance offers. For instance, in traditional finance, prime brokerages offer high-leverage yield products sourced from various avenues. Prime brokerages require undercollateralized lending to provide these services; however, protocols like Aave and Compound, fall short because of low loan-to-value caps, limiting users' ability to fully leverage yield products. This gap results in less liquidity, as LPs are hesitant to take on smart contract risk for low yields. Currently, DeFi growth is bottlenecked by a lack of prime brokerage infrastructure. While existing iterations of decentralized prime brokerages have gained traction, many struggle with generalized leverage, leaving a need for additional prime brokerage infrastructure with protocols such as Blueberry.
