Open a DApp at its original URL with a document-start OneGate-compatible NEP-21 Browser Mock, or act as one compatible remote debugger for an installed OneGate app's encrypted remote-debug interface. Inspect page state, console output, screenshots, approval requests, and dAPI traces. OneGate can also gather public project metadata, validate it against the official catalog form, prepare the exact listing request, and submit it to the public OneGateApp issue tracker only after user review and confirmation.
