Verification sounds like a chore, but it is two minutes of checking that stands between you and a login page that belongs to someone else. This is the full sequence, in the order to do it, and the reason each step exists.
Check the prefix
Every genuine Awazon address begins with the string awazon. That is the first
check and the fastest. If an address you found does not start with those six characters,
close it and move on. There is no edge case where a real mirror drops the prefix, so a
missing prefix is a definitive no. The common impostors use awarzon,
anwazon and awazoun, each one close enough to slip past a glance but
wrong in a way the prefix check catches instantly.
Check the length
A v3 onion address is exactly fifty six characters before the .onion. Count them,
or better, let the copy button do it for you by taking the address from a source you
trust rather than typing it. A shorter string is not a v3 address. A longer one has
something appended to it. Either way it is not the address you think it is, and the
difference is exactly the kind of thing that is invisible when you are reading it fast
and obvious when you count.
Check the signature
The strongest check is the PGP signature. The operator announces every mirror rotation as a signed post on the Dread forum, signed with a key whose fingerprint you saved the first time you verified it. When you see a new address, find the signed post, verify the signature against the fingerprint you have, and compare the address in the post character for character with the one you are about to use. A phisher can copy a login page. They cannot sign a post with a key they do not hold. This is the check that turns a maybe into a yes.
Check the last six
Once the page has loaded in the Tor Browser, look at the address bar and match the last six characters against what you copied. That is the final check, and it is the one you do every single time, because it is the fastest way to catch a swap that happened between copying and loading. Four checks, two minutes, and the difference between a deposit that reaches the market and one that reaches a copy of it.
