How to check official service links and signatures

Compare published addresses, fingerprints and signed messages without confusing authentication with a payment guarantee.

Check the address before opening an account

Start with a recorded service address, then compare it with the operator’s own published contact and documentation pages. Watch for different spellings, unexpected subdomains and substituted support accounts.

A listed Tor or I2P address identifies a recorded alternative endpoint. Its presence alone does not prove that the operator is trustworthy.

Check the key and the complete message

When a service supplies a PGP key, compare its full fingerprint using independently obtained operator information. A verification result only establishes that the message matches a signature from that key.

On a KYCLESS card with a PGP key, open Verify a signed letter and paste the complete signed message. Check the message’s recipient, amounts, addresses, deadline and order details rather than relying on the valid-signature label alone.

Understand what verification cannot establish

A valid signature does not prove payment, delivery, solvency or the truth of every statement in the message. A compromised or incorrectly attributed key can still sign a message.

Never submit a seed phrase or private key for verification. KYCLESS’s signature tools work with public keys and signed messages. Use the report or correction controls when recorded information conflicts.
