• Support on-chain analytics, event indexing, and data pipelines
• Document contract behavior,
assumptions, and upgrade paths
Required Skills & Experience

• Comfortable working with Git and code reviews
Nice to Have
• Experience with Layer 2s (Arbitrum, Optimism, Base, Polygon)
• Familiarity with tokenomics modeling (emissions, incentives, staking design)
• Exposure to on-chain analytics (The Graph, Dune, custom indexers)
• Backend experience (Node.js, Python)
• Prior security auditing or formal verification exposure
