Bitzum is a non-custodial Bitcoin wallet that lets you pay anyone using just their phone contact. Instant off-chain settlement — no fees, no waiting, no addresses to copy.
Familiar UX. Real Bitcoin. None of the friction.
Pick a contact, enter an amount, send. Bitzum maps phone numbers to Bitcoin under the hood so you never touch a long address.
Your 24-word seed lives on your device, in the secure enclave. We never see your keys and we can't move your money.
Bitzum-to-Bitzum payments settle off-chain in under a second — no on-chain wait, no on-chain fee.
Top up from any wallet to your on-chain Taproot address. Send and receive over Lightning too, all from one balance.
Send to any phone number — recipients get an SMS and the funds wait for them. If they don't claim, you get your sats back.
See balances and amounts in sats, BTC, or your home fiat — switch with a tap. Spot rates refresh live.
No KYC, no email, no waiting list. Just a phone number to verify so your friends can find you.
A one-time SMS code links your phone to a fresh Bitcoin wallet generated on-device.
Scan your Taproot deposit address from any exchange or wallet. Your balance updates as soon as the deposit confirms.
Pick anyone in your address book, enter an amount in sats or fiat, hit send. That's it.
Available on iOS now. Android beta coming soon.
