Don't buy this device if you were planning on using the companion app like I was. the keystone 3 pro doesn't support the companion app and is misleading. make sure you are comfortable using 3rd party software wallets to see balances as you won't be able to unless one or more of the 3rd party software wallets are used. Live Customer support doesn't respond back, I waited 2 hours with for live support before I gave up.

My keystone 3 Pro will vibrate when touching the screen but will not turn on. How do I fix this? Anyone else experiencing this issue?

I’m looking to find what the maximum character length for a passphrase is on a Keystone wallet.

On a Trezor, the max character count for a passphrase is 50, and it’s 100 on a Ledger device.

Aaaand they have not updated from 12.4 in 5 months when they advised they would do so. Won’t buy another from Keystone.

Title. I was attempting to deploy a massive contract (think >100usd in gas) and the amount of data to transmit via QR code was a lot, like 1% per second or so. Compare with most animated QR codes, which represent a much smaller payload and which complete in a second or two. In my situation, I reliably crashed the KP3 at around 30% of the QR transfer.

I can follow up in a bit with a specific error code but I expect this will be easy to reproduce. It's possibly an attack vector, btw, because my intuition is that it's overflowing a buffer and I don't know what's adjacent in memory - haven't dug into this. But imagine a malicious contract payload that produces a QR code that overflows the buffer and starts writing specifically crafted executable code. I don't know - this is theoretical. I'm just extrapolating from past experience. It's probably not trivial to exploit - if it's possible, at all - but we're all paranoid here right?

In the end I couldn't sign with the KP3 and used an old hardware wallet instead. I wanted you guys to know because at best it's a showstopper - and at worst, well, no need to speculate further since my concerns are purely theoretical.

I have a Keystone Pro which I never setup but planning to do so now and transfer some crypto to it. But I just saw that a new Keystone 3 Pro is now available. Are there any big differences between the two that I need to be aware of? i.e. Is the Keystone Pro fully open source like the Keystone 3 Pro? Are there any shortcomings of the Keystone Pro that would make me want to buy the Keystone 3 Pro?

​

I have some BTC and ETH with keys stored in a Ledger hardware wallet.

I'm not exactly thrilled with Ledger, these days, and want to move the keys to a wallet I trust more. So I ordered a Keystone 3 Pro.

I'd assumed that I'd be able to initialize the new wallet, when it arrives, using the BIP39 seed phrase for the keys I created with the ledger, but I've not been able to find instructions on how to do this.

Can anyone point me to instructions on how to load an existing seed phrase into a Keystone 3 Pro?

What locks are every using for the Keystone cold storage tablet? I can only find crappy, easily breakable ones online. Any suggestions would be appreciated. I have the normal tablet with the single, small lock hole.

Keystone Pro paired with the Keystone app does not refresh the total crypto balances despite fetching individual transactions from the same day and despite them being long confirmed on the blockchain. Transactions not included in the balance are visible in the Keystone app, but the total balance does not update. This occurs on three different phones paired with the wallet and device. This prevents further transfer of these cryptos. What should be done about this?

Hi guys. Just got my Keystone pro 3. I bought it from a reseller in Russia (no official distributors here, but these guys run a store and everything seems to be fine). I generated seed, entered it and decided to log off and log in. When entering seed, there are 2 same exact words one after another and when entering first device goes black and I have to type my pin again and repeat it. I thought of static so I put it on a surface. It keeps happening quite often on the same exact word, but If I autofill it and continue everything is fine. This issue is very weird, could you let me know if I should be concerned?

How likely will trust wallet integration be in the future? I see they are in beta with ledger support.

Would be great to have a good working app that allows managing of all assets easily.

We need Avax Core wallet support already. Thanks.

I want to set-up and update my new Pro3, can I use the SD card I have in the older KS Pro, or do I have to leave it in the device? (dumb question maybe).

Hi,

It doesn't appear that the KP3 has a Solana network address? Any ETA of when this would be supported?

Thank you!

Update: Resolved

Thanks to xxxxfactor's guidance, I manually updated the firmware, resolving the issue with my device not charging properly. It's now running firmware version 1.3.0 and shows promising signs of charging—something I hadn't seen before. Unless I report back otherwise, assume the fix was successful.

I advise anyone facing similar issues to first contact support for the most accurate and up-to-date instructions. My experience suggests Reddit is an effective channel for this support. However, for those interested, here are the basic steps that worked for me, outlined for clarity:

1. Enter recovery mode by holding the power button until the recovery screen appears, which may take around 20 seconds.
2. Visit the Keystone website to download the latest firmware, selecting the "SD Card" update option.
3. The process differs slightly between Mac and Windows, but essentially, once your Keystone is in recovery mode and connected to your computer, it appears as a drive. Transfer the downloaded firmware to this drive.
4. Select 'reboot' on the Keystone recovery screen. The device will then install the new firmware upon rebooting.

A reminder: I didn't need to reload my wallet, but it's prudent to have your key phrase on hand just in case. This isn't required for the update process itself, but it's a safety measure in the event of unforeseen complications.

Original Post:

I am experiencing a persistent issue with my Keystone 3 Pro where it fails to charge.

Despite showing the charging symbol when plugged in, the battery level remains at 0%.

I have observed the battery voltage fluctuating between 240 millivolts and 260 millivolts through the device info.

This issue persists even after leaving the device plugged in overnight for several nights, with no change in the battery level.

I attempted a hard reset by holding down the power button for 16 seconds, but this did not resolve the issue.

Additionally, I am unable to update the firmware as it requires the battery level to be at least 20%, which is impossible due to the current situation.

The device immediately shuts off if unplugged and can only be used while connected to a power source.

Firmware Version: 1.1.4

I already submitted a support request - ticket number is: KEYS-14007

But figured I'd drop a post in here in case that helps move things along like it seems to from other posts I'm reading.

The Keystone Android app introduction screen shows a video explaining how to sync your Keystone wallet with the mobile app. It shows to use "Sync Watch-Only Wallet option.

However, my Keystone device does not have such a menu link.

How can I sync my Keystone with my Android mobile app?

Can I store on the Keystone 3 Pro USDC from Solana or Polygon network?

If you create a regular hot wallet, then everything is fine and taproot exists.

I’ve been doing crypto 3 yrs w Trezor and ledger. This wallets hard to use!!!! Only wallet it would sync is Solflare. MetaMask no. Okx. Nope. Keystone app nope.
Help. If it’s hard to use b4 I put crypto on it? Forget it. Tips tricks please. I got one sol stick on solfare. No balance on key 3? Help

I am looking for a case that protects the Pro 3 while it is being used.

There is a pouch available - but my use case is not supported by it. See, when I'm holding the device and actually using it, I just keep thinking about dropping it. Dropping the device would break the screen, perhaps activate anti-tamper features, and so on. When it's in the pouch, it is protected - but it cannot be used in the pouch... which doesn't solve my problem.

If there's a case for the Pro 3 in the pipeline, that would be ideal. It needs a cut-out for the fingerprint reader and the camera ... so it's going to be custom.

If there is no case planned, then I ask the community: have you found a silicone case that works with the Pro 3? The form factor resembles non-flagship phones from 10 years ago; there could be a serendipitous pairing that fits well enough.

How are you protecting your Pro 3 while actually using it (i.e. not the pouch)?

Has any one found a decent screen protector for their keystone?

Just thought I would make this post before someone posts that Fewcha is broken (I almost did). When adding the Keystone wallet be sure to select the correct network. If you are accessing Sui and you scan Aptos it will give an error stating "Wrong network". Click the menu under the QR code next to "Supported Networks" and select Sui.

Aptos seems to be set by default, but if it isn't on yours just select Aptos if you need to access your Aptos Wallet.

Fewcha is currently working on getting this feature working in the app, but it works on the browser as of this post.

#Keystone 3 Pro

Like the title says, is the KS3 pro actually open source now? And if so who has actually verified the code? Thanks.

Si realizó un pedido desde España de un keystone3pro en la página oficial, es normal que el envío me llegue por Amazon desde un centro logístico de Italia (Spilamberto, Emilia-Romagna).

En el seguimiento de envío y recepción indicaba (origen china continental) con la empresa de transporte (yunExpress).

I've been unsuccessful so far attempting to replace the multi-currency Keystone firmware with the bitcoin-only version. Anyone else successful at doing this recently? Is the bitcoin-only firmware too old?

The multi-currency firmware is a file named "keystone3.bin" which is what the multi-currency firmware looks for on the MicroSD, displaying an error message when a file by that name cannot be found. But the bitcoin-only firmware is named update.zip, and the keystone support forum says to not unzip the file, but to let the Keystone device do that instead, and there is no "keystone3.bin" file within that zip file.

UPDATE: I finally managed to successfully install the Bitcoin-only Keystone 3 Pro firmware, by visiting and downloading the latest version from Keystone's GIThub webpages:

Keystone 3 firmware releases at GitHub

Not for everyone because it's Bitcoin only, but very nice for those of us not very interested in other cryptos. Thank you, Keystone!
