From sign-in to your first protected build.

1. Sign in with Discord

Phantom uses Discord as its identity layer. Signing in does not require a purchase — you can explore the dashboard and see your account state before buying anything.

2. Choose a plan

Plans are sold through Gumroad as either a monthly subscription or a one-time lifetime license. After checkout, fulfillment happens automatically: a license key is issued and linked to your Discord account or purchase email.

3. Submit a build

From your dashboard, upload the client jar you want protected. The build is queued and processed by the Phantom engine, which runs entirely server-side.

• Maximum upload size is 2500 KB per build.
• Only .jar files are accepted.
• Your original jar is deleted from our servers as soon as processing finishes.

4. Download the protected artifact

Once a job completes, your dashboard shows a download link for the protected jar. A mapping report is generated alongside it so support and future incremental builds can resolve renamed symbols if you ever need to.
