Topic: Mixin Safe: A Convenient and Decentralized Multisig + MPC + Timelock solution - page 7. (Read 1947 times)

If I understand the purpose of this service well, then I must ask, Why is it limited to mostly hardware wallets and Bitcoin core?
In the guides I am not seeing any talk about wallets like Electrum, Sparrow Wallet etc

Yes, hardware wallets are superior in security vs SPV wallets, but a majority of people use the latter. So why are they not recommended? Am I missing something?

I'm still reviewing this mixin safe, and currently, I'm still a little confused, but I tried to download the mixin safe messenger. If I look at it, it seems like a typical wallet like a trust wallet.

Then I'm also a bit confused if I'm obligated to buy a cold card because I saw that to have one it's around 147$ each and the morning key is around 1.1$ each here in our currency. If I use a mixin safe, is it required for me to buy a cold card and mornin key?

The package plan in test starts from $2 per year, so the reviewers do need to pay at least $2 to the standard plan to create a safe and send out a transaction.

Mornin Key is the free and easiest wallet to test, but we also have guides for Bitcoin Core and Ledger at the moment https://support.mixin.one/en/category/mixin-safe-n3u479/

Hello, I've checked your website, pretty sleek and elegantly simple which I like since it's refreshing to the eyes but I have to ask, do the reviewers have to pay when they create their wallet? Also, is Mornin Key the only available one for testers?

You cannot know from the start that the product will not have users even if it is completely centralized and even if there are better alternatives.  It can be said that it is too early to admit this.  Almost all of us know that a small percentage of users care about privacy. 
I believe that this will be concluded based on the review campaign that they intend to launch soon, by assigning 100 participants from Bitcointalk, as their evaluations will be of great benefit in assessing the project's effectiveness and profitability. Choosing bitcointalk + Royse services is a great decision to determine how much the service is efecient.

I understand all your concerns, and know that we have a long way to do a good marketing. We are not a new team, and Mixin Messenger is an old product operating for already 6 years.

But first of all, we need to make sure this is a good product, it must be secure, decentralized, and convenient. It's not a product for all, and it begins by serving the people need it well.

Thank you

I tried as much as possible to understand this service, I think I got the point, but my question is what is the benefit of this service for ordinary users? I mean, what will make the average user leave the software wallet (free and easy) or the hardware wallet and go towards this type of service (which has some degree of centralization)?

This is another point as well, users must use your other product "Mixin Messenger", and this is something that many people may not want, because the user will need to download several applications and register on the site and all these things will seem annoying and make users feel that someone is sharing their sensitive data with them.

I understand your choice. I'm not saying the product is perfect for anyone. Mixin Safe can be a much better solution for people who want a easy to use and decentralized solution to manage their coins, instead of using CEX.

And Mixin Safe is designed to be used by family or team members together, it's important to make it convenient and obvious to understand. The goal is to make BTC accessible to everyone in the world, so everyone is confident about their BTC holdings without worrying about losing their coins.

People are already using centralized banks, with all their personal information shared with the banks. Now Mixin Safe can be a decentralized bank, in a very similar approach but with BTC as the money. Mixin Safe can be a better bank for those who are already banked, and Mixin Safe is also a better alternative to CEX for those who choose CEX over wallets


Anonymous number needs to be bought and connected to a private key at first, and are only for some invited testers for now. Will be open to public very soon.

Signal third-party Twilio data breach exposed 1,900 phone numbers in 2022, and now we are supposed to trust you who are using app based on Signal and same third party Twilio?
Sorry for saying this, but I am little suspicious whenever I have to send any of my personal data for any registration.
If I had to choose between better security and convenience, I will always choose security.

I tried using anonymous number and it didn't work with Mixin.

I am from Bangladesh and use a Grameen phone sim card. Sometimes SMS comes in delayed due to network problems. But I have checked again and confirmed that I did not receive any SMS yet. About recaptcha, I don't think it's from your end. Sometimes Recaptcha behaves likes that and I have faced this issue on various platforms before.

You're welcome.

Hi, it's not like that we have your key.

The wallet is 2-of-3 multisig, which means the wallet is controlled by 3 keys, owner, members and recovery.

You have owner and members key. We have the recovery key, and the recovery key is timelocked by Bitcoin script, so that our key can only be used after your Bitcoin address is inactive for over 1 year.

So if you possess your owner and members key, our recovery key will be useless. And just in case you lost your owner key or members key, our recovery key can be used, and it can only be used together with owner or members key.  That means, if you lost both owner and members key, then our recovery key is useless as well. Because the 2-of-3 wallet  can only be accessed by 2 keys together.



All our code are open source here https://github.com/MixinNetwork

I am just trying to understand this. So Mixin Safe is a wallet where we have control over our funds as we have the private key but at the same time the Mixin Safe also stores our private key (Rename it to Onwer Key), so in case if we lose our private key, we can get help from Mixin Safe.
This may or may not be acceptable as since the site has access to our keys, they can cause harm anytime if they want. This is similar to any centralized site but in this case, we access through the Keys and the site also can access our funds. Clear me if i am wrong 

My other question is this wallet an open source or a closed source?

May you tell the country of your sim card? We use Twilio to send out verification code, there may be some issues in some countries. Recaptcha should be easy to solve, will have a look.

And thank you for the multiple posts warning, I have fixed that.

I tried to sign up using my phone number within the Android app, and getting the code was impossible. I am unsure if it's a network issue from my sim card operator or maybe from the mixin. Each time I tap on resent message, it asks to verify the recaptcha. It seems recaptcha is currently under impossible-to-solve mode. Tried a couple of times to get the OTP but failed for now.

Yes, Mixin products have the bitcoin mixing capabilities and work very well for 5 years already.

Ow, I totally misread the name, I thought it was Mixin' but hey, you learn new things. I noticed that there's an uncapitalized "mixin", is that bitcoin mixing or something? Now that I know the name, I get now what you're pitching.

A product is not for everyone. Most people use centralized exchanges or custodians for their easy to use and convenient feature. Mixin Safe is designed mainly for those people prefer convenience than understanding the tech stuff behind the scenes, but in a decentralized and secure way.

And for the phone number thing, it's the same, phone number is just a phone number, we share nothing, we never do ads or analyze data.

Anyway, you can choose to use anonymous number when get an account.



The Mixin name is from the same brand under Mixin Network and Mixin Messenger. They do have some mixin features in a decentralized way.

Mixin Safe is a product built on Mixin Messenger features, to provide a multisig+timelock Bitcoin wallet service. But with Mixin Safe, this mixin ability is reduced from the original Mixin Network.

Can anyone do a TLDR for plebs like me? Cause I doubt that I understand this project correctly, from what I read and understand, this is a kind of wallet where there are two keys and you can't open the wallet with just one, is that correct? If so, then OP should probably change the name of the project because I don't see how mixing is a feature in this.

If I understand correctly this Mixing Messanger wallet is fork of Signal app, but is there any other way to register other than entering phone number.
I tried registering with one phone number and I received data error, I also don't want to share my number for this purpose, even if app claims it won't share it with anyone.



That indirectly means phone number could be shared privately with different companies, governments and/or individuals.

It's much easier and safer to use multisig setup and combine hardware wallet with another device or a wallet, than to download and install all Mixin stuff, and pay $100 or more every year.

The link above is the beta product, you can already sign in and start using it. I know the Mixin name makes it sound like a mixer, but It's just a wallet.

To start using the product, you need Mixin Messenger, which is an MPC wallet,  to make the Mixin Safe account. And thank you so much for helping.

Sorry the website doesn't make it clear for people to understand the product, we are still polishing the website design and words.


Hi, it's a wallet service. The wallet is provided as a website to make it easy to access from anywhere, but the website doesn't hold the private keys, it's just an interface to make it easy to do multisig.

It's some kind of custodian services those companies will use, but it's built with general public in mind, the website interface is pretty easy to use, and pricing is transparent and cheap.

For security, it's better to read the post instead of the website, the website is under development and missing some points.

So Mixin Safe is a multisig wallet with three keys, OWNER, MEMBERS and RECOVERY.

The OWNER key is managed by user's own hardware wallet, Ledger, BitBox02, etc.

The MEMBERS key is also managed by user's wallets, the Mixin Messenger MPC wallet. The MEMBERS key can be managed by the user own or friends, make it difficult to lose.

And the recovery key is timelocked, and can only be used when timelock expired and must be used together with OWNER or MEMBERS key.

When I say this is more secure than a single hardware wallet, I mean hardware wallet is secure, but a single hardware wallet is easy to lose or broke, Mixin Safe uses hardware wallet, and try to eliminate single point of failure.
