Project Zero Builds DeFi-Native Prime Broker for Unified Margin

Project Zero (P0), founded by a former MarginFi developer, is building a DeFi-native prime brokerage platform to unify margin and risk management. Founder MacBrennan Peet explained the open-source system aims to solve capital fragmentation by allowing users to maintain a single margin balance across multiple, separate DeFi protocols, thereby increasing capital efficiency.

- Project Zero is built on the existing infrastructure of the MarginFi protocol and inherits its risk management systems, which have processed billions of dollars in transactions without any instances of insolvency. Existing MarginFi users will have their points automatically transferred to Project Zero. - The platform is backed by prominent investors in the crypto space, including Pantera Capital, Multicoin Capital, and Solana Ventures. - Founder MacBrennan Peet also co-founded MarginFi, Temporal, and MRGN Group, and has a background in traditional finance, having previously built a hedge fund and worked at Morgan Stanley. - The protocol initially supports venues on the Solana blockchain, such as Kamino, Drift, and Jupiter, but is designed to be chain-agnostic, allowing for future integration with protocols on other L1s, sidechains, or rollups. - Project Zero has introduced a feature called "Project 0 Pay" which allows users to borrow against their DeFi portfolio to cover real-world expenses without needing to sell their assets. Users can connect a credit card or bank account, and at the end of the month, the system calculates a loan to cover designated purchases, which is then sent to their bank account as USDC. - A key use case enabled by this unified margin approach is the ability to execute multi-venue carry and rate trades for the first time, allowing users to capitalize on interest rate deltas between different protocols. - The platform aims to democratize access to prime brokerage services, which in traditional finance are typically reserved for hedge funds and institutional investors. - Project Zero launched in September 2025 and reported $300 million in total value locked within its first three months of operation.
