Verifying the Release

In order to verify the release, you'll need to have gpg or gpg2 installed on your system. You'll first need to import the keys that have signed this release if you haven't done so already:

curl https://boltz.exchange/static/boltz.asc | gpg --import

Once you have the required PGP keys, you can verify the release (assuming boltz-client-manifest-v2.12.0.txt.sig and boltz-client-manifest-v2.12.0.txt are in the current directory) with:

gpg --verify boltz-client-manifest-v2.12.0.txt.sig boltz-client-manifest-v2.12.0.txt

You should see the following if the verification was successful:

gpg: Signature made Mon Dec 15 16:00:38 2025 CET
gpg:                using RSA key 8918FFBFFB49E93EF256D930542A7F22A3BD9CB0
gpg: Good signature from "Boltz (Boltz signing key) <admin@bol.tz>" [unknown]
Primary key fingerprint: 8918 FFBF FB49 E93E F256  D930 542A 7F22 A3BD 9CB0

You should also verify that the hashes still match with the archive you've downloaded.

sha256sum --ignore-missing -c boltz-client-manifest-v2.12.0.txt

If your archive is valid, you should see the following output (depending on the archive you've downloaded):

boltz-client-linux-amd64-v2.12.0.tar.gz: OK
