You can scan, or copy and paste the following:
- The On Chain address (starts with bc1).
- Create a Lightning invoice (lnbc1).
- Use the LNURL address which uses email address form (usuarioBBW@ln.bitcoinbeach.com).
You can also make internal transactions by user name. But this is exclusive for BBW users, as this name is not shared with other similar applications like chivo or strike.
