How to send bitcoin on-chain or over Lightning
After clicking “Send”, choose “Bitcoin” wallet, then scan or paste the recipient’s Bitcoin address, LNURL, Lightning address, BOLT11 invoice, or BOLT12 offer. You can also open the QR scanner from the top left of the mobile app screen.
You can view amounts as bitcoin (₿1) or sats (100,000,000 sats) by changing the unit under “Account”, then “Bitcoin”.
If you send bitcoin from your cash balance, Strike applies a 1% spread to the conversion. If you send from your bitcoin balance, only network fees apply. A Lightning payment settles in seconds for a small network fee that Strike passes through with no extra charges. An on-chain payment lets you trade cost for speed by picking a delivery time before you confirm:
| Delivery time | Estimated arrival | On-chain fee |
|---|---|---|
| Priority | ~10 minutes | Higher |
| Standard | ~1 hour | Lower |
| Flexible | ~24 hours | Zero |
How to send money to another Strike user
Individuals in all US states except Hawaii can tap “Username”, then type your recipient’s username or pick them from your contacts. Strike saves anyone you’ve paid before, so you don’t re-enter their details. To remove a contact, go to “Account” and “Contacts” and swipe left on the contact’s name.
Any payment request you receive will appear on the respective balance tab in the mobile app. To stop receiving unwanted requests, open it, tap “Block” in the top right, and confirm. To unblock someone later, open “Account”, select “Profile”, then “Blocked users”. Swipe left on the username, tap the red “Delete” button, and confirm.
You can earn fee-free trading by referring friends to Strike.
