It's open source, and it seems like it has been around for some time.
Alternatively, you have multiple other wallets (that claim to be non custodial but there's is no way to confirm it) like Trustwallet, Exodus, etc.
I just want to ask how long have you been using this wallet (xaman) that you shared here? Because the one I used was the trustwallet, when did this xaman wallet start? Because if it's okay based on your experience if you've used it and you didn't have any issues with it, I might add it to the wallet I'll use anyway.
It's better to have other wallets where crypto assets are hidden than just one to keep potential coins thinking if it can give me good savings in the future,
and this exodus I have a little in it honestly speaking.
