Verify announcements signed by 0trace
0trace publishes important announcements — security advisories, key rotations, listing acknowledgments — signed with the PGP key below. Use this key to confirm any such message was issued by 0trace and has not been tampered with.
For per-order Guarantee and Receipt documents the service uses a separate Ed25519 signing key — see Verify.

Compare it with the value you see when running gpg --fingerprint after import. If the two strings differ, do not trust the imported key.

1. Import the public key directly from the website:
curl https://0trace.io/0trace-pgp.asc | gpg --import
2. Or import a downloaded copy:
gpg --import 0trace-pgp.asc
3. Confirm the imported fingerprint matches the one published on this page:
gpg --fingerprint hello@0trace.io
4. Verify a signed message:
gpg --verify announcement.txt.asc
A successful verification proves the message was signed by the holder of the 0trace private key and the contents have not changed since signing.
- PGP (this page)— signs public communication: announcements, advisories, listing acknowledgments. Private key lives offline and never touches production servers.
- Ed25519 (/verify)— signs per-order Guarantee and Receipt documents automatically for every exchange. A different key, generated independently.
Compromise of one key does not affect the other.
Instant exchange.
