What's new in 2.8.5

ETHEREUM → KADENA BRIDGE: FIXED
Since 2.8.3, choosing the Ethereum→Kadena direction left the token list at 'loading balances…' forever, and neither Simulate nor Execute did anything. The Kadena→Ethereum direction worked, so it looked like the bridge or the relayer: it was not. It was our bug, introduced in 2.8.3 with the fallback-node change: four bridge functions asked for the Ethereum node using a variable that did not exist there, and crashed before asking anything.

Also, if the balance query fails for any reason, the reason now shows under the list instead of sitting at 'loading'.

UNDER THE HOOD
A new test reads main.js and checks that every handler declares the variables it uses: that is exactly how this bug slipped in, and neither the syntax check nor the library tests could see it. The automated tests go from 139 to 219 checks.

Frequently asked questions

Is Koberlet free?

Yes. No subscription and no app fees; you only pay the usual network fees.

Who holds my keys?

Only you. They are generated on your device and never leave it. DNNS cannot see or move your funds.

What if I lose my phone or computer?

Restore the wallet on another device with your 12-word seed. Keep it on paper, offline.

Why is the iPhone version on TestFlight?

Apple requires a registered company to publish wallets on the App Store. TestFlight is Apple's official channel to distribute the app meanwhile; it is free and updates itself.

How do I verify a download?

Compare the SHA-256 fingerprint shown next to each download with the file's: certutil -hashfile file SHA256 on Windows or shasum -a 256 file on Mac and Linux.
