BRD is the best way to get started with bitcoin. Our simple, streamlined design is easy for beginners, yet powerful enough for experienced users.

Fastsync

Fastsync is a new feature in the BRD app that makes Bitcoin wallets sync in seconds, while also keeping BRD technology ahead of the curve as SPV slowly phases out. When Fastsync is enabled the BRD wallet uses our server technology, Blockset to sync, send and receive instantly!

Your Decentralized Bitcoin Wallet

Unlike other Android bitcoin wallets, BRD users have the option to disable Fastsync converting the wallet into a standalone bitcoin client. It connects directly to the bitcoin network using SPV mode, and doesn't rely on servers that can be hacked or disabled. If BRD the company disappears, your private key can still be derived from the recovery phrase to recover your funds since your funds exist on the blockchain.

Cutting-edge security

BRD utilizes the latest Android security features to protect users from malware, browser security holes, and even physical theft. The user’s private key is encrypted using the Android Keystore, inaccessible to anyone other than the user.

Designed with New Users in Mind

Simplicity and ease-of-use is BRD's core design principle. A simple recovery phrase (which we call a recovery key) is all that is needed to restore the user's wallet if they ever lose or replace their device. BRD is deterministic, which means the user's balance and transaction history can be recovered just from the recovery key.

Features

• Supports wallets for Bitcoin, Bitcoin Cash, Ethereum and ERC-20 tokens, Ripple, Hedera, Tezos
• Single recovery key is all that's needed to backup your wallet
• Private keys never leave your device and are end-to-end encrypted when using iCloud backup
• Save a memo for each transaction (off-chain)

Advanced Setup

Blockset Client Token

The Blockset client token can be set in gradle.properties or by using -PBDB_CLIENT_TOKEN="<client token>". A default token is available for testing.

Firebase

To enable Firebase services like Crashlytics, add the google-services.json file into the app directory. Without this file, runtime Firebase dependencies are still used but do not start and the Google Services gradle plugin is disabled so builds will succeed.

BRD is open source and available under the terms of the MIT license.
