  • Capable of on-chain data analysis — able to trace transactions, decode contract call chains via block explorers or RPC calls.
  • Understanding of mainstream DeFi protocol mechanics (e.g., Aave, Uniswap, Curve, PancakeSwap), including Lending, AMM, and Staking models.Multi-chain development experience is a plus (Ethereum, BSC, Arbitrum, etc.), with awareness of cross-chain differences and compatibility considerations.
  • Proficient in using AI-assisted development tools in daily workflows; experience with prompt engineering, AI-driven code generation, or integrating LLM-based solutions into development pipelines is highly desirable.
  • Open to AI-augmented approaches for smart contract analysis, protocol research, and test case generation; demonstrated ability to identify and apply AI solutions to improve engineering efficiency.
  • Passionate about technology with high standards for code quality and development practices; strong team communication and collaboration skills.
  • Strong logical thinking, excellent problem analysis and resolution abilities, with a high sense of responsibility.
