Bull Bitcoin with Feijoin deposit/withdrawal options and trading applied by default

Bull Bitcoin has made Payjoin optional for bitcoin (BTC) exchange deposits and withdrawals while enabling it by default for on-chain buys and sells through its exchange-connected BULL Wallet, Bitcoin Magazine reported on the 5th. The company claims to be the first exchange to offer Payjoin on deposits and withdrawals, though the report offered no comparison data on other exchanges' support. The app's version 6.15.0 changelog lists Payjoin as the default setting for exchange buy/sell and invoice payments as of October 22, 2026, with users able to disable it per transaction. The move matters because Payjoin can obscure transaction flows and improve privacy for exchange users, a feature typically absent from custodial trading. What to watch next is whether other exchanges follow Bull Bitcoin's lead and whether default-on Payjoin sees meaningful adoption without disrupting withdrawal workflows.
