Please describe your proposed solution.

How?

To keep track of the already minted NFTs we will connect a smart contract on Milkomeda with the policy ID on Cardano. We will create a systen that keeps track of which NFTs have been minted on which chain and prevents the smart contract or the Cardano Minting Tool from double-mints.

This tool will be integrated natively into NMKR Studio (formerly NFT-MAKER PRO) so that artists, developers, etc. can simply select on which chains they want to launch their NFTs and go.

Then the user experience for the buyer of the NFT will be very simple. They will be able to select either a Cardano Wallet (Nami, Eternl, etc.) or a Milkomeda Wallet (Flint, Metamask) to mint their new NFT and it will be minted automatically on their chosen Blockchain.

Please describe how your proposed solution will address the Challenge that you have submitted it in.

By creating this cross-chain functionality for minting NFTs we are going a very big step toward cross-chain collaboration. We believe it's essential that end-customers have options to choose from. Using the proposed solution they'd be able to choose on which blockchain they receive the NFT and it will be trivial for artists & developers to launch collections on multiple chains at once, bringing the space further together.

What are the main risks that could prevent you from delivering the project successfully and please explain how you will mitigate each risk?

While we as a team are very experienced in Cardano Development, we are not that experienced in EVM development. To mitigate that risk we are talking with multiple EVM experts and will be relying on their help in addition to our own competencies.

Please provide a detailed plan, including timeline and key milestones for delivering your proposal.

Milestones:

1. EVM Minting Smart Contract: 5 Weeks Development
2. NFT Status Tracking Service: 4 Weeks Development
3. Adaptations to Cardano NFT Minting Solution: 3 Weeks
4. Integration into NMKR Studio (formerly NFT-MAKER PRO): 2 Weeks Development
5. Bug Fixing and extensive Testing: 2 Weeks

Please provide a detailed budget breakdown.

If you are funded, will you return to Catalyst in a later round for further funding? Please explain why / why not.

Not for this specific project. We have planned our budget accordingly.

Please describe what you will measure to track your project's progress, and how will you measure these?

We will create monthly written reports about the status of the project and will share them with the Catalyst Community.

What does success for this project look like?

Artists will be able to launch their NFT collection on multiple chains at once and end-customers can simply choose on which chain they want to receive their NFT. All this will be doable through a simple to-use GUI.

Please provide information on whether this proposal is a continuation of a previously funded project in Catalyst or an entirely new one.

Its a new proposal.
