Private And Secure Bitcoin Wallet
BULL by Bull Bitcoin is a self-custodial Bitcoin wallet for iOS, designed for secure, private, and efficient management of Bitcoin, Lightning, and Liquid Network transactions. Ideal for both everyday payments and long-term storage, it empowers users to get paid, buy Bitcoin, spend Bitcoin, manage wallets, and securely hold assets with ease. Built on cypherpunk principles, BULL prioritizes user sovereignty, open-source transparency, and trustless operation, integrating cutting-edge technologies to make self-custody safer and simpler without compromising privacy or security. From a single BIP39 seed backup, it creates two interoperable wallets: an Instant Payments Wallet on the Liquid Network for seamless daily Lightning transactions and a Secure Bitcoin Wallet for on-chain payments and robust long-term storage.BULL is Bitcoin-only, segwit-native, and optimized for performance, with no clutter or distractions. It leverages cutting-edge technologies like PayJoin, Liquid’s confidential transactions, and atomic transfers to make self-custody accessible and secure while upholding cypherpunk values of privacy, sovereignty, and decentralization. Free and open-source, BULL is the ultimate platform for managing Bitcoin payments and securing assets for the long haul.
Perfect wallet. It has all I need. Self custody, lighting, liquid. I can connect it to y own node.Amazing!
Disappointing-EDITED
nednarB93
It was rolled out as “The best mobile bitcoin wallet of all time.” It can’t even load balances of existing wallets. With such big talk I expected waaaaay more from this wallet.EDIT: The recent 6.4.0 update fixed this. The wallet now talks to my server and updates balances. It’s got some more tweaks needed, but I wanted to correct this ☝️
