This is really a surprise for me.
I implemented a mobile wallet and used Secp256K1 KeyPair

And this is a problem that I need to fix, or add a second provider, or specify two addresses. Users will not see their assets and will consider them lost
You can also make requests to two addresses and display them in the interface.
Damn, I was against seed from the very beginning. It is better to use simple cryptography without add-ons.
