    A few questions:
    1. Is the project already running or are we building from scratch?
    2. Which blockchain network are you mainly targeting?
    3. Do you already have smart contract architecture/docs ready?

  • Naresh S.

    Hi Muhammed, before discussing technical fit I’d like to understand whether your current priority is building new protocol/product features from scratch or stabilizing and optimizing already deployed smart contracts and backend infrastructure? Also, regarding Whitechain’s ecosystem, are developers expected mainly to work within standard EVM-compatible DeFi patterns, or does the role also involve deeper infrastructure responsibilities such as custom validators, RPC/indexing architecture, cross-chain interoperability, or protocol-level performance/security improvements?
    Thanks
