At Solana Breakpoint 2025, Project 0 founder MacBrennan Peet outlined a thesis that institutional investors have long waited for: a functional, decentralized prime broker. While attempts at cross-margining have faltered on Ethereum due to latency and cost, Peet argues that Solana’s execution layer is the only environment capable of supporting a generalized prime brokerage at scale. The protocol, which launched in September 2025, has already amassed $300 million in assets by unifying margin across disparate venues, starting with Kamino and its own P0 venue.

The core value proposition lies in capital efficiency for the yield-seeking investor. Currently, DeFi users face fragmentation—lending on one platform while borrowing on another requires over-collateralization at both ends. Project 0 eliminates this by sitting as a layer above venues like Drift, Jupiter, and Loopscale. This architecture allows users to execute multi-venue strategies, such as carry trades (long spot, short perp) or basis trades, within a single margin account. With Drift integration slated for January and Jupiter Lend for early Q1 2026, the platform is positioning itself as the primary interface for complex, delta-neutral yield generation.

Peet also announced Project 0 Pay, a product launching in January that fundamentally rethinks crypto-to-fiat off-ramps. Unlike typical debit cards that liquidate assets at the point of sale, this infrastructure allows users to borrow against their entire yield-bearing portfolio to settle credit card bills (e.g., Amex or Chase) at the end of the month. This ensures investors maintain their exposure to assets like Solana and continue earning yield, rather than triggering taxable events or losing market position to pay for daily expenses.

Underpinning these products is Brutus, the protocol’s risk engine, which currently powers production variables for spot assets. A V2 upgrade next year will introduce fully dynamic, on-chain updates for LTVs and interest rates, extending support to derivatives. The roadmap culminates in the Project 0 Token launch in Q1 2026, contingent on the platform achieving majority market share among Solana lending venues—a milestone Peet expects to hit as the derivatives integrations go live.
