Breadwallet represents a standalone service to keep cryptocurrencies. The wallet does not have servers, which reduces risks of possible hacking. Breadwallet is based on SPV scheme – the system is connected to the bitcoin network providing fast and effective experience on the mobile device. The wallet is secured by a paper key – the system generates 12 random words for every new wallet. The paper key should be kept in safe, as it is required for upgrades and recovery.
The wallet comes on IOS devices. It is open-source app and HD (hierarchical deterministic).
