PROFILE
Zhenqian
Zhenqian contributed to the KeystoneHQ/keystone3-firmware repository, focusing on multi-chain wallet integration, transaction signing, and UI reliability. Over four months, Zhenqian delivered features such as SUI and Cardano transaction hash signing, Medusa and Nexus wallet support, and Safe contract hash display, while addressing stability and memory management. The work involved C, Rust, and Solidity, leveraging skills in blockchain integration, embedded systems, and cryptography. Zhenqian’s approach emphasized robust unit testing, dependency management, and user experience improvements, resulting in a more secure, interoperable firmware. The depth of engineering addressed both user-facing enhancements and core reliability for hardware wallet workflows.

Mar 1, 2025March 2025 performance highlights for KeystoneHQ/keystone3-firmware: Delivered Keystone Nexus integration enabling new connectivity paths. Expanded wallet ecosystem with Beacon Wallet, Babylon Wallet, and Backpack on Sui, plus support for Baby Coin, Neutaro, and Nufi (with entrypoint), significantly broadening interoperability. Implemented UX/privacy refinements and surface-area reductions by hiding Cake Wallet UI, removing boot text artefacts, and eliminating Avax-related components and the Avax coin. Strengthened stability and correctness through ADA crash fix, ERC20 parse fix, rebase bug fix, Babylon mainnet chain ID fix, and unit test fixes. Added USB CLI support and fixed image conversion utility to improve device interaction and reliability. Overall, these efforts improve business value by expanding supported wallets/tokens, reducing risk, and accelerating go-to-market for wallet integrations.
