Smart Contract Audit Deep Dive: Royco's Tranche-Based DeFi Protocol | Hexens

Description

In this live audit retrospective, the Hexens and Royco teams walk through the full security engagement behind Royco's junior and senior tranche protocol — from scoping and audit approach to key findings and mechanism changes made before launch. We cover: - What Royco is and how the tranche model works - Why the team chose to audit right before launch - How Hexens approached reviewing a tranche-based financial protocol - The rolling commit process and how both teams coordinated fixes close to launch - Key findings, incentive risks, and how the audit shaped the final design Lessons for builders designing structured or economic mechanisms Whether you're building a protocol, preparing for an audit, or interested in how security and mechanism design intersect — this one's for you.
