Security

Block Wallet is created as an on-the-go wallet. This means security is a priority but so is easy accessibility. By the use of your device's fingerprint reader when available in combination with a passcode (pincode) when you create a transaction you are protected without hinder. Read more on GitHub.

AES Encryption with passcode

All data stored on your device is AES encrypted. Within the encrypted datastore the 'private key' is stored encrypted (again, double encrypted). It is protected with a passcode you can change to your liking. The 'private key' is only decrypted when needed.

Transactions signed on device

The 'private key' does not leave the device. It is only decrypted when you sign a transaction. After this is done the key is encrypted and when the key is safe the signed transaction is send to the blockchain through SSL.

Backup with Recovery Phrase

Write down the recovery phrase on a piece of paper and store it somewhere safe. When your device is lost or you would like to transfer the wallet just install Block Wallet and enter the recovery phrase on the new device.

Opensource

All code which is used to generate, store and sign the transactions is opensource and can be used in security audits. You can make a Fork on GitHub.

Support

If you have any issues or suggestions you can visit the GitHub issues page.

Host your own RPC server

Block Wallet uses Go Ethereum as a backend to retrieve transaction and token data. Instead of using the free secure and up-to-date blockwallet.eu hosted geth you can host your own. Just change the RPC Server within the settings of the Block Wallet App and point them to your host.

Get the Private Key

Block Wallet uses BIP39 to create your Recovery Phrase. If you would like to get the plain-text 'private key' behind this phrase you can visit the Keytools Page for more information.
