From the Play Store description:
Mixin Messenger is an open-source cryptocurrency wallet and signal protocol messenger, which supports almost all popular cryptocurrencies.
It supports Bitcoin, Ethereum, EOS, Monero and thousands of other cryptocurrencies.
Mixin Messenger is built on Mixin Network, it’s a PoS second layer solution for other blockchains. Mixin Network is a distributed second layer ledger, so you own your crypto assets. Because of this second layer, it’s normal that you can’t check your BTC address balance on a Bitcoin blockchain explorer.
More information about how its wallet functions can be found on this Zendesk article “Guides for Wallet”
We emailed the Mixin development team on September 16, 2021, to verify whether they have custody of the private keys. We await their response.
The repository is linked in the description.
It appears that this wallet is non-custodial and that source-code is available.
An issue has been made on Gitlab with the corresponding results.
Issue has been raised in MixinNetwork’s Github Issues page.
Do your own research
In addition to reading our analysis, it is important to do your own checks. Before transferring any bitcoin to your wallet, look up reviews for the wallet you want to use. They should be easy to find. If they aren't, that itself is a reason to be extra careful.
