Episode notes
On-Chain Prime Brokerage Changes Capital Fragmentation
- Project Zero is an on-chain prime broker that unifies capital across multiple DeFi venues to reduce fragmentation and improve capital efficiency.
- Making the prime brokerage on-chain enables real-time verifiability of venue solvency and safer credit underwriting.
Validate Venues Before Underwriting Credit
- Validate integrations before offering credit and only underwrite venues with proven risk engines and security track records.
- Build integrations selectively to avoid underwriting immature venues and limit contagion risk across the credit pool.
Prioritize Spot Coverage Before Derivatives
- Project Zero will first focus on spot lending coverage on Solana then add derivatives to keep risk manageable while maturing the risk engine.
- The team prioritizes mastering spot credit risk before tackling complex derivatives and Greeks.
