(Real Bitcoin is not supported)

• Air-gapped test Bitcoin sending
Coconut Wallet works together with the Coconut Vault app to enable safe, hands-on Bitcoin sending practice.
Coconut Vault operates as an offline cold wallet — it only works when all network and Bluetooth connections are completely disabled, and cannot be used even if developer mode is enabled.
The Vault securely stores sensitive information such as private keys, while Coconut Wallet imports a watch-only wallet from the Vault to perform air-gapped Bitcoin transaction practice.
