To protect your privacy, the BitPay App generates new addresses for your wallet automatically after you use a bitcoin (or bitcoin cash) address one time.
All bitcoin and bitcoin cash transactions are public, traceable, and permanently stored in the blockchain. For these reasons, bitcoin and bitcoin cash addresses should only be used one time and users should not disclose their addresses. When addresses are re-used, they allow others to more easily and reliably determine that the address being used is yours.
Q: Do my addresses expire?
A: No, old or previously-used addresses never expire.
Q: I have received funds in my "old" address and generated a new one. Will I receive my funds?
A: Yes. When funds are sent to an address, they will be received in that destination address. Generating new addresses in your wallet does not affect transactions to old addresses.
Q: I cannot generate more addresses. I get an error saying “Empty addresses limit reached. New addresses cannot be generated."
A: To facilitate scanning funds, the app prevents the user from creating more than twenty empty addresses. Until you use the latest address created, you will not be able to generate new addresses.
Q: How many addresses can my wallet generate?
A: Your wallet is able to generate infinite addresses. However, you may only have twenty empty addresses at one time.
