Quentin Perrot-Minnot contributed to LedgerHQ/ledger-live by engineering robust cross-chain wallet features and improving blockchain integration reliability. Over 16 months, he delivered and maintained modules supporting Bitcoin, Ethereum, Solana, and Cosmos, focusing on transaction handling, fee estimation, and test automation. Using TypeScript and JavaScript, Quentin refactored coin modules for protocol upgrades, standardized API and bridge patterns, and enhanced CI/CD workflows for deterministic testing. His work included integrating new assets, modernizing dependencies, and resolving critical bugs affecting transaction flows and user experience. These efforts resulted in a more maintainable codebase, improved release readiness, and expanded asset support across desktop and mobile platforms.

Jan 1, 2026January 2026 performance: Strengthened cross-chain token transfer reliability and testing coverage for Ledger Live. Key features delivered include BEP20 Token Sending Validation Improvement (ensuring correct asset-type handling for native assets vs BEP20 transfers); Support for blast and blast_sepolia currencies in fee calculation to ensure accurate 'send max' operations; and expanded BSC testing with max-transfer coverage and refactored coin tester module. Major bugs fixed include MultiversX API Timestamp Clamp and Tests (clamping timestamp parameter to minimum 1 with tests); Memo Length Validation to block overly long memos by mapping memo errors to transaction errors; and Cardano Snapshot Update with suppression of ContractKit source-map warnings to improve integration and UX. Overall impact: increased reliability and user confidence in cross-chain transfers, reduced invalid-transaction scenarios, and expanded cross-chain capabilities with better testing infrastructure. Technologies demonstrated: API validation and error mapping, test-driven development, cross-chain fee logic, testing infrastructure, snapshot maintenance, and dependency warning management.
