BitKey provides tools for individuals to manage their own private-keys and use Bitcoin easily.


BitKey is a simple bitcoin wallet, with no account required. You can encrypt, store and manage your bitcoin keys within your own control. With the iCloud synchronization ability, data can still be retrieved even if the phone is lost or app deleted.

Design Principle:

1. Never Lose Data.
2. Encrypt Everything.
3. Decentralized & Anonymous.


1. BitKey provide pure tools to manage your bitcoin keys.

2. BitKey is a cold bitcoin wallet. Everything is keep decentralized, encrypted and anonymous.

3. BitKey use iCloud to sync and backup your data (which encrypted).

4. Every time your data changes, there will be a version of the backup, you will never lose any of your data.

4. You should set up your own encrypt password to protect your bitcoin keys.

5. You can set touchID to protect your app.

6. BitKey generate address and key pairs locally.

7. BitKey can sign a transaction message locally.

How It Works:

#1 Q: How does the Bitkey application work as a cold wallet.

A: Bitkey has no app server. All your data(bitcoin address and private keys) is saved locally, and backup in your own iCloud document.

And, the data backup in your iCloud document is encrypted by your password. Actually, the raw bitcoin private key just temporary exists in your device memory (RAM). (When you use the key to sign a transaction locally). So with the excellent iOS sandbox isolation mechanisms we can define Bitkey app as a cold wallet.

#2 Q: How can I withdraw my funds?

A: It's a cold wallet, you just use it to keep your bitcoin keys safe from stolen or lost. The concept “withdraw my funds” usually be used in the context of “hot wallet/website” or “bitcoin market website”.

# 3 Q: How can I add money to my account?

A: It's a cold wallet, you just can import bitcoin private keys to the app.The concept “added money to the account” usually be used in the context of “hot wallet/website” or “bitcoin market website”.

#4 Q: How can I make a transaction / pay?

A: Bitkey provide “transaction sign tool”, you can use the tool to sign a transaction locally and then broadcast it to the bitcoin network.


1. At the first launch of the app, You should allow the app to use your iCloud.

2. At the first time you launch the app, You should set up your encrypt password to protect the data.

3. Then every time you launch the app you need enter the password to decrypt your data.


Your encrypt password will never stored on your device or upload to iCloud. It just temporary exists in memory to decrypt data after you enter them. Without the password there is no way to decrypt your data. So when you set or reset the password you may should always provide some appropriate password hint. The password hint will be backup and uploaded to iCloud.
