COLDCARD's anti-exfil/klepto very simple solution. Some call it Libsecp256k1... Such sophistication, much wow. https://github.com/switck/libngu/blob/356b9137cf7ddf5de66ec4cdc0a4d757b2e42790/ngu/k1.c#L244

I think the numbers make other more important numbers safe.

So, does Coldcard and/or Tapsigner support anti-klepto/exfil? Any official doc talking about that? We would like to have the correct info on wallets.thebitcoinhole.com

In order to exfill you will need to break libsec256k1, if that's broken Core is broken.

Are you using that lib also for Tapsigner?

English version please. Or at least a grade 6 level. I assume this is security on the secure chips?
