The WabiSabi protocol is a proven open-source non-custodial solution. We evaluated the WabiSabi protocol, which is used by Wasabi Wallet and now Trezor, as the best in its category. Trezor coinjoin requires a coordinator with high liquidity and a high number of users for the best privacy gains and smooth user experience. zkSnacks coordinator has the highest volume and usage among existing solutions, which guarantees high privacy gains for the users.

Trezor coinjoin relies on Tor identities and block filters, so neither Trezor nor the coordinator run by zkSnacks can learn any sensitive data about the coinjoin participants.

On the contrary, coinjoin is a privacy tool that shields users from blockchain surveillance as it severs the links to past transactions.

Tropic Square: The SE prototypes are being tested at the moment! No ETA on the production launch at the moment.

Regarding the coordinator question. Once a reputable coordinator with similar liquidity as the zkSnacks coordinator appears, we will consider it for inclusion. High enough liquidity is necessary for smooth operation of coinjoin rounds.

That’s a great question that should be asked and discussed more! Personally I believe that Shamir backup has qualities that are quite useful for inheritance planning. I have actually written an article on how to approach inheritance with Shamir backups: https://bitcoinmagazine.com/technical/protecting-bitcoin-shamir-backup. I think the crucial thing is to have some sort of “treasure map” that will become accessible to the family in the case something happens to you. Such treasure map would explain the nature of the inheritance and the location of the Shamir shares (not necessarily precise addresses to prevent theft if an “evil maid” discovers it). The precise inheritance plan is an individual thing, but I think there are some basic recommendations everyone should follow, as I describe in the linked article.

As for Trezor’s plans around this topic: we’d like to inform our users more about the use cases for Shamir backups such as this one.

This is something we are discussing right now in the R&D. Integrating hardware wallets and lightning network is tricky, because the former is almost always offline, while latter needs to be always online. I hope we will share something soon, so we could get opinion from the wider LN community.

I love it and it's a great showcase on what we can build with the power of bitcoin!

Main advantage of Wasabi compared to Samourai is for us bigger liquidity and more simple experience that can ensure smooth service for all our users.

Payjoin is already prepare on Trezor firmware level.. However there are no plans currently for the implementation in Trezor Suite.

We are not too happy about that, but we still believe that this is one of the the best existing solutions. zkSnacks coinjoins have the highest volume and user participation on the market and therefore we can achieve the best level of privacy.

Trezor with an optional coinjoin is a better product than Trezor without one. The act of blacklisting helps prevent coins that are under active surveillance from being included in the coinjoin, ensuring privacy is preserved for other participants.

Trezor coinjoin is fully optional, non-custodial and open source. If for any reason users don’t like this function, they don’t have to use it and nothing changes for them in terms of using their Trezor.

Are you aware they have bitcoin-only firmware? Or do you mean hardware which really can only support bitcoin? Not sure if this is possible

Correct, we do have a bitcoin-only FW you can use today.

It is possible to use multisignature transactions with your Trezor device and Electrum and other popular multisig wallets, however it is not yet implemented in Trezor Suite. There are no specific plans for multisig implementation in Trezor Suite.

Here is our co-founder @stick showing demo of the multisig usage with Trezor and Electrum Wallet:

Altough Trezor Suite does not support multisig natively, Bitcoin multisig is the first class citizen in Trezor. You can sign multisig transactions on Trezor with almost any wallet that supports both (multisig and Trezor), such as Bitcoin Core, Electrum, Sparrow, etc.

We plan to continue to support U2F.

Not only we plan to keep U2F support, we are also the first FIDO2 (successor of U2F) device with a display where you can see what credential is being used for authentication.

Yes! Currently 3.

Hi, please have a look on these articles:

That describes the best practices. But feel free to ask more specific questions.

We prefer to leave the decision of which cryptocurrency to use the discretion of our users. Our focus is to keep improving hardware wallet functionality and usability, which ensures user privacy and security when transacting bitcoin or any cryptocurrency our users are interested in. One such feature is the improved notification system in our Trezor Suite application to alert users whenever they may be interacting with scam tokens.

I'm happy with that. I've lost money to shipcoins, now it's time for the next batches of people to do the same while I stack cheap sats to recover my losses before they wake up and pump the price. It wouldn't be fair if they skipped that stage. Also, supporting shipcoins makes the Trezor device cheaper, which I can't complain about either.

Thanks for raising that up. It was already fixed last year.

I hear you. The new technical changes to Google Chrome has introduced technical challenges that would require a large reallocation of resources to developing the Password Manager, holding back the development of other products with higher priority. That being said, we are well aware of the use case (and usefullness of the solution being it's die hard fans ourselves!) and hoping to see it back on the roadmap once the resources allow for it.

Both devices (Trezor Model One and Trezor Model T) already support PSBT. However I don't know about good UI implementation so far.

Yes, we aim to popularize Shamir Backup more in the future through various types of educational content such as our recent tutorial video:

According to a survey conducted by the Cambridge Center for Alternative Finance in 2020, it's estimated that around 101 million people around the world currently own Bitcoin or some other form of cryptocurrency. It's worth noting that this estimate is based on self-reported data, and the actual number of Bitcoin owners may be higher or lower than this estimate. (Credit: ChatGPT)

My answers:

Out of those 100+ bitcoin/crypto users, I estimate some 10 million to be in self-custody (10%). So a lot work to be done! 📈

As for the obstacles to wider adoption, I believe we need to make self-custody even more user-friendly and stress free. Bitcoin and crypto has been around for a relatively short time compared to the "paper with pictures on it" and its nature might confuse the newcomers entering the market. We are working on a lot of new products and educational initiatives to build confidence and reassurance in the newbies.

Trezor is never shipped with a preloaded firmware. Users have a choice to choose either universal or bitcoin-only firmware during the onboarding.

What are we doing in Ghana? The answer is supporting local bitcoin meetups and educating people about bitcoin and self-custody (the curriculum for the Trezor Academy is stricly bitcoin-only).

On the product level (as in feature richness), bitcoin is where we started, is close to our hearts, and such has been getting priority treatment. On the security level, we ensure the security of all the users via the open-source security model embedded in our tech.

We spend much more time on Bitcoin than on all other coins combined. We were the first HW wallet to implement Bitcoin multisig, we were among the first HW wallets to implement Bitcoin Taproot, we were the first wallet to implement Bitcoin Coinjoin, the list goes on, we are the first hardware wallet thinking about integrating Lightning Network. We wouldn't be able to bring so many innovations on the table if what you are suggesting was true.

We usually have Pilsner Urquell and Birell as a non-alcoholic variant :-). And we actually have a Trezor Beer Fund where satisfied users can send us tips! https://trezor.io/support/a/trezor-beer-fund

Thanks.

New mobile app (beta, read only) is launching soon. Like in the coming weeks soon..! Then, we are super excited about new HW products to drop later this year and also other planned for next year.

:D .. I might be baised, but I am very proud we have run on a pretty humble company culture.

Yes, safe to use. CE marking is mandatory in the EU, see https://en.wikipedia.org/wiki/CE_marking for more info
