Three things, done carefully.

  • The Review screen before sending 23.620248 USDT: recipient 0x7099…79C8, network Arbitrum One, max network fee 0.027012 USDT, estimated time about 5 seconds.

    Send, after a real review.

    Before you confirm, see the recipient, the network, the maximum fee and the time. Transfers usually settle in about five seconds.

  • The Receive screen: the QR code for the wallet address, with the Arbitrum logo at its center.

    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 Swap screen: pay 10 USDC, receive 9.915 USDT, with a minimum of 9.885255 USDT.

    Swap USDC and USDT.

    Routed through LI.FI. See the rate and the minimum you’ll receive before you swap.

A send screen warning: this address looks very similar to one in your history but is different. A checkbox asks you to confirm you checked the full address.

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.

Your keys never leave your phone.

Kryn is self-custody: only you can move your funds.
