Yes. Ballet wallets are manufactured using a patented two-factor key generation process that utilizes the BIP38 open-source standard. Therefore any cryptocurrency wallet that has fully implemented BIP38 can be used to access the coins stored on your Ballet wallet. This means you can be confident that if for any reason the Ballet Crypto app gets delisted or the company is shut down in the future, you will still be able access to the coins on your Ballet wallet.
