March 2026 monthly summary: Across LedgerHQ/device-sdk-ts and LedgerHQ/clear-signing-erc7730-registry, delivered features and fixes that improve interoperability, testing reliability, and on-chain domain accuracy. Key work includes unifying EIP712 descriptor handling across v1/v2, improving Docker/Speculos testing tooling, aligning registry descriptors and on-chain domains, and enhancements to ABI/schema migration tooling and PR/CI processes. These changes reduce deployment risk, accelerate iteration, and demonstrate strong proficiency in TypeScript/Node, container tooling, EVM ABI handling, and CI automation.

February 2026: Focused on enabling scalable schema migrations and robust test coverage for ERC-7730 registry with automation to reduce manual work and accelerate delivery.

January 2026 monthly summary: Delivered the ERC-7730 Registry upgrade to Version 2 via an automated migration script, including schema updates, field transformations, and cleanup of null values. No major bugs reported; data quality improvements reduce downstream issues and simplify future upgrades. This work strengthens data integrity and interoperability in LedgerHQ's clear-signing registry, enabling smoother downstream integration and setting a foundation for future registry upgrades.

LedgerHQ/app-ethereum — August 2025 monthly summary: Delivered a focused UI feature that enhances ERC20 call visibility by displaying extra data (trailing calldata) in ASCII or hex, improving debugging and auditing capabilities. This aligns with product goals of better data transparency in on-chain interactions and supports faster issue diagnosis for ERC20 flows.

February 2025 — Focused on expanding vault interoperability and tightening robustness in the clear-signing-erc7730-registry. Key deliverables include ERC-4626 Vault support enabling yield-bearing vault interactions and improved asset management, configuration visibility with constants display and corrected routing for reliable resource loading, and mandatory type checking on address name formatters to prevent data-type errors. These changes improve reliability, security, and developer productivity, while enhancing interoperability with ERC-4626 vaults and reducing maintenance risk.
