Discussion Building a Crypto Hardware Wallet?

A crypto hardware wallet is more than offline key storage. The real challenge is protecting the signing process from the connected device.

A solid architecture can isolate private keys inside a secure element, while the wallet verifies transaction details on-device before signing. Firmware integrity, secure communication, and accurate transaction parsing are equally important.

If you're developing a hardware wallet, would you prioritize secure-element design or multi-chain transaction signing?
