Hi Emilse,
Could you please let me know whether the smart contracts, API specifications, and content ownership workflows are already defined, or if the role also involves helping shape the Web3 architecture, user monetization flows, and wallet interaction experience as the platform evolves?
Thanks

Can you please answer below questions
1. Which blockchain network and wallet integrations are planned initially?
2. Do you already have smart contracts and backend APIs ready? -

Which blockchain network(s) and wallet providers are you targeting for the platform, and are the smart contracts already deployed with finalized APIs/ABIs, or will frontend development need to coordinate with ongoing contract development?
-

A few quick questions:
1. Do you already have the smart contracts deployed, or do they still need development?
2. Is the backend API already ready, or do you need support with Express.js and MongoDB as well?
3. What is the current stage of the platform — planning, development, or MVP already built?
