Signal: what it is and how to use it

Signal is an end-to-end encrypted messenger, widely adopted. It helps you talk about a P2P trade or ask for help without exposing the content, and since 2024 it lets you start chats with a username.

How do you use Signal?

  1. Download Signal from the official site, signal.org, or the official phone store, checking the developer name.
  2. For your crypto identity, sign up with a separate number, such as an eSIM one (for example, from Silent.link), not the number tied to your public identity.
  3. Create a username so you can start chats without sharing your phone number.
  4. In the privacy settings, stop people from finding you by your number.
  5. Test with trusted contacts before using it in a trade with real value.

What are the limits and cautions?

  • Sign-up still requires a phone number. A number used in two identities links them, so use a separate number for your crypto identity.
  • No app removes metadata entirely, and the phone's operating system remains a relevant factor.
