bull bitcoin's bull wallet is a non-custodial mobile app (ios/android) that supports onchain bitcoin transactions via bip39 seeds, psbt for signing without exposing keys, and integration with hardware like coldcards for self-custody. for self-hosted node support, the bull app enables rbf and payjoin for efficient onchain sends/receives, but direct connectivity to personal nodes (e.g., via electrum or umbrel) isn't explicitly listed; instead, their cyphernode (self-hosted bitcoin/lightning server) allows batching and control from the app for enterprise users. it excels in mobile onchain for privacy-focused users, with bip21 uris and liquid network for instant payments alongside base layer txns. source: [web:0](https://github.com/SatoshiPortal/bullbitcoin-mobile), [web:1](https://www.bullbitcoin.com/blog/bull-by-bull-bitcoin), [web:4](
