Nov 1, 2025November 2025 (LedgerHQ/ledger-live): Key Tezos reliability improvements and test-suite enhancements. Delivered a production-ready fallback for Tezos fee estimation when the sender's public key is unavailable, backed by integration tests to validate the new behavior. Also completed a comprehensive refactor and stabilization of the Tezos API test suite to improve validation of transaction structure, public key handling, and mainnet references, with updated fee representations and cleaner formatting. The work reduces production risk and strengthens long-term maintainability. Key deliverables: - Tezos Fee Estimation Fallback Without Sender Public Key: fallback fee estimation for Tezos transactions when sender pubkey is unavailable; includes integration tests. Commit: 5c6e8475857bd01037255ce2cc642941fd7b7e6e - Tezos API Test Suite Improvements and Stability: consolidates/refactors tests, validates transaction structure and public key handling, updates mainnet references, adjusts fee representations, and cleans test formatting. Representative commits include fmt (59f2887c79b582985701010ba686273e1f56aadd), index.ts update (867344ac017cbf4e3833361e77827230786d76a8), pubkey handling fix (8d666e36cfc9d8ae99d2de29f0c4eff83b974e7f), test adjustments (547a371ef730c1becb8e44e49a2bdc18e22de7df), review/lint (1bddd1c44e02827142216d29d97afcdadbdf8df2, 6349ceb9c4b950c8f3520b260578eed5f63a6aad). Impact and value: - Improved transaction reliability for Tezos in Ledger Live, reducing user-impacting failures. - Increased confidence in Tezos-related changes through robust integration tests and better test hygiene. - Demonstrated proficiency with TypeScript, Tezos coin module specifics, test automation, linting, and code quality practices.
