A mobile messenger that combines encrypted messaging and bitcoin payments in a single app has emerged. Radar Chat is designed to let users send and receive bitcoin directly in chat windows without opening a separate wallet app or copying wallet addresses. It uses the Lightning Network and has tested payments up to $5,000. The app adopts a self-custodial structure in which users hold their own private keys and receive a seed phrase for recovery.

The U.S. Treasury has added PayPal and Venmo payments to its Pay.gov form that allows the public to make voluntary donations to reduce the national debt. The program has operated since 1961, with about $67 million received since 1996 and around $30,000 in February 2026. Donations remain small compared with total U.S. debt of $39 trillion and monthly interest costs of about $88 billion. A proposed bitcoin reserve bill remains stuck in committee.
