Start by obtaining your device, then install its companion app from an official channel. During setup, create a PIN that is private to you. Your recovery phrase is the critical backup: write it down in the correct order and store it somewhere secure, offline, and accessible to you alone. Never photograph it, save it in a notes app, or share it with anyone. A legitimate support representative will never need those words.

Before sending or receiving assets, understand the network and verify the full address. When approving a transaction, compare its destination and amount on the wallet’s own screen—not only on your computer or phone. Test transfers can help, though they do not remove all risk.

Keep your software current, be skeptical of unexpected links, and slow down when a message creates urgency. Self-custody is not a one-time setup; it is a steady practice of protecting your backup and checking what you sign. Begin with small steps, learn from official educational resources, and never invest more than you can afford to lose.
