Demonstration Introduction Satochip stands for S ecure A nonymous T rustless and O pen Chip . It is a javacard applet that can be used as a secure hardware wallet running for example on a Yubikey Neo. The Satochip applet has full BIP32/BIP39 supports. Using Satochip, an initial BIP32 seed is imported in the javacard and private keys are derived as requested by an external application. Private keys are never exported outside of the secure chip . To improve performances, the result of key derivation is cached in secure memory for future requests so that a specific derivation path is only computed once. The Satochip also supports the import of regular (non-BIP32 keys) such as vanity keys. Here again, private keys cannot be exported outside of the secure chip. Up to 16 regular keys can be imported on the chip. In any case, the private keys can be used to sign transactions and Bitcoin messages, if sufficient credentials are provided. Access to private keys (creation, derivation and signature) is enforced through the use of PIN code (from 4 to 16 chars). This software is provided 'as-is', without any express or implied warranty.
