About

Satochip is a multi-asset hardware wallet in a credit-card form factor. For Bitcoin, the first-party product page documents BIP-32/BIP-39 key storage, PIN protection, NFC or smart-card-reader connectivity, and setup with Sparrow Wallet. The open-source JavaCard applet keeps derived private keys inside the secure chip and signs transactions when authorized. The catalog’s Bitcoin L1 tag reflects its Bitcoin support; the device also supports non-Bitcoin assets.
