Ledger Signer Verification
Confirm that the RAILGUN app on your Ledger was signed by Anon before you approve the install.
Anon signs the RAILGUN Ledger app with a dedicated installer key. Your Ledger device displays a short fingerprint of that key during installation. If the fingerprint on your device matches the one below, you are installing the genuine, Anon-signed app. If it does not match, stop and do not approve the installation.
Status: experimental. This attestation is published for transparency and independent verification. Details may change as the signing process is finalized.
