Bitcoin addresses do not expire, so they can technically be reused. However, reusing addresses can create privacy, security, and spendability risks.
Bitkey addresses are created using your App Key, Hardware Key, and Bitkey’s Server Key. If you replace either of the keys you control—such as when replacing your hardware device or performing a App Key Recovery—addresses generated with the previous keys may become difficult or impossible to spend from.
What to expect
- If the address was created after a Delay + Notify recovery—or if you’ve never completed one—funds sent to that address will remain accessible in your wallet
- If the address was created before a Delay + Notify recovery, funds sent to that address should still be accessible
💡 Tip: For better privacy and security, use a new bitcoin address each time you receive funds in Bitkey.
