Ledger is closed source so their claim that their chip is secure is what they said but what cannot be audited publicly.
That much is true, but does not hinder an anti-klepto implementation regardless. Their excuse is shitcoins and being lazy to build the tooling around it
Closed source and lack of anti-klepto is a red flag. nostr:nevent1qvzqqqqqqypzq3huhccxt6h34eupz3jeynjgjgek8lel2f4adaea0svyk94a3njdqy88wumn8ghj7mn0wvhxcmmv9uq3uamnwvaz7tmwdaehgu3dwp6kytnhv4kxcmmjv3jhytnwv46z7qpqms59v4syvcssf0msyxa9pk393ndnvdz4wyz6t257v2urms6e7q5qxfv8q8
