Features
Three things, done carefully.
Receive with a QR code.
Share a QR code or copy your address, shown in groups of four so it’s easy to compare. The screen spells out what you can receive: USDC and USDT on Arbitrum One.
Swap USDC and USDT.
Routed through LI.FI. You see the rate, the 0.85% fee and the minimum you’ll receive before you swap, and the network fee comes out of the token you pay with.
Security
Your keys never leave your phone.
Kryn is self-custody: only you can move your funds. Every transaction is built, checked and signed on your phone, so our servers can’t change where your money goes.
Look-alike addresses, caught.
Scammers send tiny amounts from addresses that look like ones you’ve used, hoping you’ll copy the wrong one. Kryn compares every new address with your history, warns you, and asks you to check every character before you continue.
Created and kept on your phone
Your recovery phrase and keys are encrypted with your phone’s secure hardware (Secure Enclave on iPhone, Android Keystore on Android) and your PIN. They never reach our servers.
Your PIN, Face ID or fingerprint
Unlock and approve with your PIN or biometrics. Repeated wrong PINs pause new attempts, and the app locks itself after a minute in the background.
Every swap checked before you sign
Kryn decodes each swap before signing and checks that the tokens come back to your own address, at least at the minimum you were shown.
Private screens stay private
On Android, screenshots are blocked on the recovery phrase, PIN and review screens. On iPhone, they’re hidden while the screen is recorded or mirrored, and covered in the app switcher.
No accounts
No email, no phone number, no ID. The app signs in to our servers with a signature made by your wallet, on your phone.
