After two years of development, the wallet with a focus on sovereignty and privacy is now available worldwide also for iOS.
Bull Bitcoin has announced the global launch of BULL Wallet, a mobile Bitcoin wallet that aims to reconcile the technical needs of experienced users and accessibility for beginners. Now available on both iOS and Android, the wallet focuses on privacy, security and ease of use.
Francis Pouliot, founder and CEO of Bull Bitcoin, stated:
“BULL is Bitcoin-only, fully open-source, and built to prioritize privacy, security and simplicity. This is only the beginning: we will keep improving it forever.”
Among the technical features, the application adopts a descriptor-based Segwit-native architecture and uses the BDK (Bitcoin Dev Kit) library. The wallet supports BIP39 seed phrases and allows connection to full-nodes or Electrum servers.
Additional functionalities include manual UTXO management, the Replace-by-Fee (RBF) option and testnet compatibility. The source code is publicly available.
Focus on privacy
The application does not collect user data, does not send push notifications and does not track IP addresses. It also supports the Payjoin protocol. The wallet also introduces BIP85-based secret derivation and confidential transactions via the Liquid sidechain.
Multi-chain and atomic swap
BULL Wallet operates on three networks: the Bitcoin mainnet, the Lightning network and Liquid. Using non-custodial atomic swap technologies based on Boltz, users can transfer funds between the three networks.
For Lightning payments, the wallet offers a user experience without the need to manage channels or liquidity. Small payments received on the Liquid network are automatically converted to bitcoin once a customizable threshold is reached, set by default at 0.01 BTC.
Integration with exchange and hardware wallet
For Android users, BULL Wallet offers optional integration with the Bull Bitcoin broker, allowing purchases, sales and payments directly from the wallet.
The wallet can also be used together with a hardware wallet: initially it will be compatible with Coldcard Q1, with integrations planned for other devices.
Backup and future roadmap
At launch, Recoverbull is included, a new backup solution for hot wallets.
The company has outlined a roadmap that includes integration of the Ark network, support for Silent Payments, secure and anonymous metadata backup, full support of all major hardware wallets, multi-sig wallet and Miniscript integration, Nostr-based anonymous chat and Lightning Network addresses.
