This repository is unmaintained, BRD iOS has moved to https://github.com/breadwallet/brd-mobile

BRD is the simple and secure wallet for bitcoin, ethereum, and other digital assets. Today, BRD is one of the largest non-custodial mobile wallets used by over 6 million users and protects an estimated nearly $7B USD.

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 iOS 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 iOS security features to protect users from malware, browser security holes, and even physical theft. The user’s private key is stored in the device keychain, secured by Secure Enclave, inaccessible to anyone other than the user. Users are also able to backup their wallet using iCloud Keychain to store an encrypted backup of their recovery phrase. The backup is encrypted with the BRD app PIN.

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.

WARNING:

Installation on jailbroken devices is strongly discouraged.
