That's rare... the Key-ID looks fine but where did you downloaded the pubkey?
How about GPG, have you downloaded the latest version from the legit source or is it preinstalled in your system?
Try to get everything to the latest version, then retry.

For reference, here's a reliable source of their public keys: github.com/spesmilo/electrum/tree/master/pubkeys

Have you setup an Electrum wallet already where your Trezor is setup as the signing device? Do you already have some experience in using your Trezor together with Electrum? (I have doubts, you have any experience yet. I mean, a or rather any Trezor doesn't have a lot of keys...)

If not, I would highly recommend that you create a Testnet3 or Testnet4 wallet, get some appropriately matching Testnet coins and practice, practice, practice.

With Testnet coins, which you can get practically for free if you ask here nicely, you can gain experience to do all sorts of things with your Trezor connected to Electrum.

Gain experience, boosts confidence.


Oh, and by the way, do you think, we can read your mind and know which Trezor you have? No, we can't!

How about you tell us also which Trezor you have? Might be a good idea, actually.

From the email that Kraken sent to you, you can use three methods to verify your withdrawal address, it may not be necessary be signing message with bitcoin address.

The 2FA verification will be very fast. Or you did not set 2FA on the exchange? Set it and you can use it.
Or if you have small amount on your wallet, you can send it to your address on the exchange. But I still prefer the 2FA.

It is possible.

After you have connected your Trezor wallet with Electrum, click on tools -> sign/verify message. Input the address and the message and click on sign. It will generate you the signature.

The message, your bitcoin address and the signature are what you needed on kraken.

About the signed message that others have suggested; there's no standard way to do it yet.

So if you decided to use your Electrum and it's not an old legacy wallet with '1' addresses, you should include a note stating that it's signed with Electrum.
Otherwise, the recipient might use an incompatible client or message verification tool and fail to verify your message.

For example: "This was signed with Electrum and must be verified using Electrum or other compatible clients/tools"

We’re reaching out to let you know about upcoming updates to how crypto deposits and withdrawals are processed. As we have recently acquired a MiCA license, these changes are designed to align crypto with the security standards already in place for traditional financial systems.

What’s Changing

Beginning August 1st, 2025, some deposits and withdrawals will require additional verification steps. These updates are part of the EU’s broader regulation of crypto assets.

Here’s how we’re keeping it simple:

Wallet Verification for deposits from private wallets: If your private wallet deposit or withdrawal exceeds €1,000 in value, or if you’re using a new wallet address, you’ll be prompted to verify your wallet ownership.

Future Ease: Once a wallet is verified, future transactions with that same address won’t need further verification.

Seamless Verification Options

We’ve made the verification process straightforward and secure through one of three methods:

Self-Certification: Verify ownership with a simple one-click process and a quick 2FA security check.

Satoshi Test: Send a small transaction from your wallet to confirm ownership. We’ll guide you every step of the way.

Digital Signature: Connect your wallet and sign a unique message we generate. The message is non-transactional: signing it doesn’t move any funds. It simply confirms that you control the private key for the address.

What This Means for You

Starting August 1, 2025, when making a qualifying deposit or withdrawal, you’ll be guided through the wallet verification process. With verified wallets, your experience remains fast and seamless for future transactions.

If you have any questions, Kraken Support is here to help.

We’re committed to providing you with a secure, reliable, and user-friendly

I congratulate you to reach one of first step in the forum, and wish you will maintain your good posting habits, but you should correct your post a little bit. LoyceV, instead of LouseV

No one. It's "airdropped merits". When the merit system was introduced, everyone received the minimum amount of merits according to their rank.

That being said, based on your post history, you're not the kind of spammer for which the Merit system was introduced, so have some Merit

why create a new ann thread? seems that this project has been here for quite sometime already. the current volume in crex is not looking good. is this the reason why you are "reviving" this coin?

no I didn't. I let it plugged in.

Really? well, i have downloaded it but haven't send any bitcoin to it yet. Will send some when i get enough from my sig campaign.

Ok. I sended a small amount to bittrex using ledger and it worked like that.

When I tried to send a transaction as usual there appeard a messagebox named "Ledger Wallet Authentication".
Looked like this

It asked me to match the character between the stars with my security card.
In this case the *2* was meant. So I took my security card got to "Digits" and looked what character or number was there below (white sign on black background). I typed this in the blank field and clicked ok.
Then it asked me again but a different character was put in stars. I looked again at my security card for the character. Typed in the character/number below it and pressed ok.
I had to do this process 4 times and finally the payment was send.
That's it
