State Channel Security Analysis

Research notes and tools for analyzing state channel implementations across DeFi protocols.

Focus Areas

• Payment channel dispute resolution timing
• Frontrunning windows in state transitions
• Cross-chain state channel bridging security
• ZK-proof based channel closure verification

Background

Independent security research. Previously at Trail of Bits (2021-2024). Princeton CS '19, focused on distributed systems and network security.
