Mapped checks & review guidance (3)
Private key material
Never ship private-key material in a client. Revoke/rotate the compromised key and hold it server-side or in a hardware-backed store.
Browse this categoryExpired signing certificate
Renew the signing certificate; ensure validity extends well beyond the app's expected lifetime.
Browse this categoryBIP-39 wallet seed phrase
A mnemonic seed phrase must never be embedded — any holder controls the wallet. Move funds to a new wallet immediately and never bundle key material.
