What's new in 2.16.13

BRIDGE: WHAT YOU RECEIVE

- Under the Amount box you now see what arrives on the other side: "You receive: 39 kb-USDC".
- The bridge delivers the same asset under its name on the other side: USDC arrives as kb-USDC, kb-KDA arrives as KDA, and the other way round. You used to have to know that.
- It updates as you change the amount, the token or the direction.

Frequently asked questions

How do I get USDC to start with?

There is a step by step guide from a bank transfer to kb-USDC on Kadena: from your bank to Koberlet.

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.

Does this site use cookies?

No. No cookies, no analytics, no trackers, which is why there is no banner to accept. Only the light or dark theme is stored in your browser if you change it. The conditions are in the terms of use.

Where do I get help?

In the Kadena Telegram group. Nobody from Koberlet will ever ask for your seed or password.

Suggestions and bugs

What people send us and where it stands. Everything gets written down, even if it takes a while.

SuggestionIn progress

Export transactions to CSV for tax filing

A CSV file with the account movements, so they can be declared without copying anything by hand. Desktop Koberlet already exports the history to CSV; on mobile it is being polished, and it will use the same columns so a spreadsheet opens it the same way whichever app it comes from.

SuggestionDone in 0.61.0

The price, somewhere fixed

Show the exchange rate on its own tab, or link to the price the wallet follows. Today the price is used to convert balances, but there is nowhere to look it up and it does not say where it comes from. It will be done showing the source and how old the figure is: a number without that is worth little.
