a year ago

We built HongbaoBTC, a web app that lets you design and print Bitcoin paper wallets styled like traditional banknotes — but with a twist: you can add your own face (or someone else's) in the portrait area.

It’s a fun way to make crypto gifting more personal and tangible. Inspired by cultural traditions like hongbao (red envelopes for gifting money), HongbaoBTC lets you gift Bitcoin with a personal touch — perfect for birthdays, Lunar New Year, or any special occasion.

Features: Upload a portrait , choose style

Pick a theme (e.g., Ghibli, Marvel, Simpsons etc)

Automatically generate:

QR code linked to a Bitcoin address

Printable banknote-style PDF

Space for the public address and private key

We’re a small team experimenting with ways to bridge digital assets and physical experiences. Feedback and ideas welcome!
