# Export the master derivation key from a wallet

POST

/v1/master-key/export

Export the master derivation key from the wallet. This key is a master “backup” key for the underlying wallet. With it, you can regenerate all of the wallets that have been generated with this wallet’s `POST /v1/key` endpoint. This key will not allow you to recover keys imported from other wallets, however.
