We launched the first Metaplex candy-machine v3 (CMv3) User Interface in Nov. 2022.
As the docs did not have any UI for developers to use, we decided to open-source the one we built for the ecosystem. Our CMv3 UI has all candy-guards directly integrated and can be utilized for developers as reference.
If your team is looking to build a unique minting experience, feel free to reach out to us. We have extensive experience in setting up mints for projects that require custom development.
