BULL BITCOIN

Bull Bitcoin 6.15.0 NEW - Swap recovery: swaps waiting for a claim or refund now show a Retry button in transaction details. It completes the swap directly on-chain through your own Electrum server, so a stuck swap can be recovered even when the swap provider is unreachable. - Payjoin controls: Send and Receive each have their own Payjoin switch, off by default. Updating keeps your previous setting. Advanced settings use simple numeric fields, with minimum amounts in sats and session expiry in minutes. SECURITY AND PRIVACY - Safer transaction acceleration: before offering to speed up an unconfirmed transaction (Replace-By-Fee), the app checks that the transaction in your history carries valid signatures from your own wallet. This blocks an attack where a malicious Electrum server shows a look-alike transaction that pays the attacker. If the check fails, acceleration is refused and you can report the transaction to support. - Payjoin requests go through a relay on a different domain from their directory and reject redirects, so your IP address is not exposed to the directory. - Payjoin 1.2.0 strengthens validation of proposals, fees, amounts and server responses. RELIABILITY - Fixed a startup error ("App Init Error") that could affect users updating from older versions: affected devices recover on their first launch of 6.15.0, with no data loss. Database upgrades now run only in the app, each step completes fully or not at all, and an interrupted upgrade or first launch finishes cleanly on the next launch. - Payjoin now uses new directory and relay servers, replacing one that is shutting down, and shows the Bitcoin QR code faster when a server is unavailable. - Payjoin results are detected in seconds instead of waiting for a full wallet sync. - Encrypted vault backup and recovery keep one verified Tor connection across screens, wait until Tor can carry traffic, and give the first onion connection more time. - When prices are unavailable, Send and Receive offer bitcoin units without fiat amounts instead of showing outdated rates. - Clearer Payjoin diagnostics in exported logs. - Updated design components across wallet, send, backup, PIN and settings screens.
