A list of addresses cannot open the onion for you and report back. No directory, however careful, can stand in for the one test that actually counts: you open the address in Tor Browser, and it is either the market or it is not. Everything below is about making that test reliable.
The character test
An onion is 56 base-32 characters before the dot. Retype one and a single wrong letter does not fail loudly; it opens a different, usually unrelated, site. So do not retype. Copy, paste, and confirm the last six characters in the address bar match what you copied. The tail is the fastest part to eyeball and the part people mangle most.
| You copied | Bar shows | Call |
|---|---|---|
| …w6bocfc7aqd.onion | …w6bocfc7aqd.onion | match, proceed |
| …w6bocfc7aqd.onion | …w6bocfcaq4d.onion | one letter off, do not log in |
| ….onion | ….onion/watch/ | a clearnet relay, not the market |
The signature
The mirror list is signed with a PGP key. The fingerprint is 7B9B 9A54 D16D 55FB F0A2 29DB E992 C670 CAD8 A2AB. Verify it out of band the first time: a Dread post, a Telegram message, a word of mouth. After that, a new signature over a changed list is how the market signals a rotated address. If an address you had saved stops resolving, look for a new signature before you trust a "updated" link from somewhere else.
