Your assets.
Your peace of mind.

ONE SYSTEM · TWO ROLES

Two apps. Each with a clear purpose.

Use KT Wallet on its own, or connect it to KT Cold Signer on a separate offline device. In the paired setup, only public addresses, signing requests and signed results cross between devices.

BUILT FOR REAL TRANSACTIONS

Less friction. More clarity.

From your first backup to your next transfer, the important details stay in view.

Your assets, across eight networks

Network icons, clear asset grouping and filtered activity. The same symbol never replaces a token’s network and contract identity.

A backup you can encrypt

Export a wallet’s recovery phrase as a password-encrypted QR image. Import and decrypt it locally with the password. Keep both safe: a lost password cannot be recovered.

A smoother way to unlock

With biometric authentication selected, the online wallet prompts automatically at startup. If it fails or you cancel, choose a retry or your wallet password.

Review before you sign

Recipient, network, token contract, amount and fee have their own place. Sensitive key access and final transfer authorization remain protected by authentication.

Both apps support three languages. Language and display currency are separate from security settings, and each wallet owns its own backup.

100% OPEN SOURCE · MPL-2.0

100% open source.
Frontend. Backend. Both apps.

The online wallet, offline signer and backend gateway are all in the public repository. Read the code, build it yourself and examine how the pieces work together. Security starts with transparency—not a promise of zero risk.
