BULL Wallet exists for one reason: to let users manage bitcoin directly, without custody, without abstraction, and without being pushed into bad habits for the sake of convenience.

Since the public release, development has been continuous, with weekly improvements driven by real usage, direct user feedback and volunteer contributors on our GitHub.

Version 6.5 focuses on fundamentals and also enhances the user experience and adds tools that experienced users expect while keeping the interface usable for newcomers.

Here’s what’s new in this version:

Private Human Support Chat

Support from Bull Bitcoin is now accessible directly from the wallet through a private in-app chat. This connects users to the same battle-tested human support team available on bullbitcoin.com, without introducing custody or third-party intermediaries.

Here's how you can get in touch with a seasoned Bitcoiner and ask for support:

Stay Up To Date

A long-requested feature, the Bitcoin Price Graph is now integrated directly in the wallet. It can be accessed from the home screen and updated to display your preferred currency, giving users a clear view of market context while staying fully in control of their keys. You can also change the currency directly by clicking on the price.

An Announcements Feed has also been added, allowing official platform updates to be delivered inside the wallet rather than through external channels.

BULL Now Speaks Your Language

BULL Wallet expands Multilingual Support with French, Spanish, Finnish, Ukrainian, Russian, Dutch, Italian, Portuguese, and Mandarin: you can change the Language in the App Settings.

We open-sourced the translations: the project remains open to community contributions via Weblate, so you can directly add languages and suggest changes and corrections in existing languages available.

A long-requested feature, Dark Mode has finally arrived. You can enable it from the Theme menu in the App Settings.

Advanced and Privacy-Oriented Options

Autoswap

Autoswap behavior is now opt-in. Upon upgrading to the newest release, users are presented with a clear screen allowing them to enable or disable Autoswap.

The recommendation remains the same: keep minimal funds on the Instant Wallet and store meaningful balances on Secure Bitcoin or Hardware Wallets. The choice, however, is entirely yours and is no longer implicit.

Custom Mempool Server

Aside from pointing the wallet to a custom Electrum Server, advanced users can now point the wallet to a custom Mempool Server for fee estimation and transaction exploration. Users can change both Electrum Server Settings and Mempool Server Settings from the Bitcoin Settings menu.

Running your own infrastructure remains the gold standard, and BULL Wallet does not stand in the way.

UTXO and address handling

This release introduces a revised labeling system that applies system labels automatically to confirmed buy and sell transactions coming from the Bull Bitcoin exchange. These labels cannot be removed. All UTXOs displayed in coin selection now show their labels, including inherited context from exchange transactions and source addresses. Address labels are also visible directly from the addresses view.

The goal is practical clarity. Users can immediately see where coins originate, avoid mixing unintentionally, and maintain clean spending behavior over time without relying on external tools or guesswork.

Sending, Receiving, and Internal Transfers

The Send and Receive flows now include an explicit wallet selector. Users can override automatic routing and deliberately choose between Secure Bitcoin (on-chain), a specific imported wallet or Instant Payments (Liquid) wallet when initiating a transaction.

Transfer swaps can now be used to move Bitcoin between all wallet types, including between your Secure Bitcoin wallet and your imported Hardware Wallet.

For Developers:

Experimental BIP85 alias support has been introduced for advanced users who want to derive child seeds or passwords with explicit labeling. This feature remains experimental and intentionally gated behind developer mode, with clear warnings about manual backup requirements.

BULL Wants to Hear From You

User feedback is at the heart of what makes BULL Wallet unique. We encourage you to send feedback directly through the in-app support chat.
