Clarification Board Ask a Question

  • Uthman M.

    This sounds like an interesting opportunity and I would love to learn a little more about the product and team before moving forward.

    Questions:
    Could you share your company website and explain which blockchain networks the payment and settlement infrastructure currently supports?
    Is the €4,500 budget a monthly salary, a contract rate, or a fixed project budget?
    Can you describe the current stage of the platform and the main deliverables expected during the first month?
    Who would I be working with directly across engineering, product, and infrastructure teams?

    Breakdown:
    Appears reasonably genuine because the scope is detailed and aligned with the budget. Verification should focus on confirming the company, product, and team structure before proceeding.

  • Shobi K.


    A few questions:
    • Which EVM networks are currently supported?
    • Are the smart contracts already live or still being developed?
    • What does your current backend stack look like?
    • Are there plans for Layer 2 or cross-chain integrations?

  • Naresh S.

    Hi Jesse, could you please let me know whether the immediate priority is expanding an existing payment/settlement infrastructure already running in production, or building new wallet, liquidity, and blockchain transaction services from the ground up while defining the core architecture?

    Thanks
