PROFILE

Martin Pastyřík

Martin Pastyrik enhanced the trezor/trezor-firmware repository by improving Cardano mnemonic handling and upgrade-data-integrity testing. He introduced binary mnemonic storage and refactored the Cardano derivation process to accept binary mnemonics, adding a conversion utility for cryptographic operations. Using C and Python, Martin ensured that Cardano public keys and chain codes remain consistent across firmware upgrades by developing comprehensive upgrade tests. He also refreshed UI fixture data to align with current development and testing needs. His work demonstrated depth in cryptography, embedded systems, and test automation, addressing both data integrity and maintainability within the firmware’s evolving codebase.
