About this app

Cash on your phone. As simple as Apple Pay, as fast as a text message, and as open as email.

Duality is a self-custodial wallet that finally makes bitcoin feel like money you can actually use. Spend it, send it, get paid in it, in seconds, with no bank or middleman taking a cut.

MONEY THAT MOVES LIKE A MESSAGE
Payments settle over the Lightning network in seconds, not the three-day "pending" you're used to. Send, and it's done.

TWO POCKETS, ONE WALLET
Keep a Digital Cash balance to spend day to day, and a Bitcoin balance to hold. Swipe between them, and convert one to the other in a tap.

GET PAID LIKE EMAIL
Claim your own Lightning address: you@dualitywallet.money. Anyone, on any Lightning wallet, can pay you. No app lock-in, no account numbers.

PAY IN A TAP
Tap to pay over NFC, or scan any QR code with Quick Pay. Save the people and places you pay often as Favourites and settle up in two taps.

SIGN IN WITH A PASSKEY, NOTHING TO WRITE DOWN
Create and unlock your wallet with your fingerprint or face. Your passkey is saved to your Google account, so there's no 12-word phrase to lose and a new phone restores your wallet in seconds. Prefer the classic way? A recovery phrase is one tap away.

YOUR KEYS, YOUR MONEY
Your keys are generated on your device and never leave it. There's no account, no email signup, and no company that can freeze, spend, or block your balance. No analytics or tracking, in the app or on our site.

SECURED BY BITCOIN
Duality is built on Spark, a bitcoin layer 2, using the Breez SDK. Your money is secured by the most open, decentralised monetary network there is. Value you hold directly, not an IOU.

Money without middlemen. Download Duality and try it today.

Self-custodial means you're in control and responsible for your own access. Bitcoin's value can go up and down. Duality is not a bank and does not offer insured deposits.
