I have reviewed your requirements and the project brief. And I will honestly say that we are the ones who can implement your turnkey project!
I must say that your budget is significantly underestimated...
Write me privately, let's discuss in more detail.
After consultation, our process will look as follows:
- clarification of the project brief (approval)
- agreement on terms
… - setting up a project repository, architectural decisions
- layout and integration of web3 library on Vue.js, integration of smart contracts into the dapp, dapp integration with a crypto wallet, backend development, blockchain scanners, and transaction recording in the database (dapp development)
- Deployment and launch of the dapp for testing (client participation required)
- Server and domain setup (server preparation)
- Project deployment in production
- handover of code repository to GitHub and server access
Additionally, we can:
- write contracts of any complexity (solidity smart contract development) - if needed, as it is not specified in the project brief, we need to clarify this point with you.
- Test contract on the testnet (smart contract testing)
- Deployment on testnet, mainnet (as agreed with the client)
- Contract code verification (if needed)
