Security begins before connection. Ensure you are operating within a sanitized environment. The Tor Browser is the only supported client for accessing DarkMatter Market .onion services.

• Download Tor Browser from the official project source only.
• Set Security Level to Standard or Safer (Javascript is required for Captcha).
• Do not resize the browser window to non-standard dimensions to prevent fingerprinting.

DarkMatter utilizes PGP (Pretty Good Privacy) for all server identity proofs. Before entering credentials, verify the signed message on the login page against the official market public key.

Why this matters: This cryptographic signature confirms you are communicating with the authentic DarkMatter server and not a MITM (Man-In-The-Middle) attack node.

Use only cryptographically signed mirrors. The links provided on this portal are verified hourly against the market's canary.
