Toshi PQ1 is post-quantum firmware for a production-grade secure element. Keys are generated on-chip and signatures are produced on-chip. The host device never touches private key material. Every signature output carries the device attestation, signed message, and verification chain. The first production hardware wallet issuing ML-DSA-87 signatures, built jointly by Anthony and Drew Derbidge.
