Aug 1, 2025Month: 2025-08 | Performance Review Summary: Focused on strengthening core ledger reliability and data usability in the splice-wallet-kernel. Delivered two major features in the core-ledger-client: (1) TransactionParser Unit Test Coverage with robust mock data and edge-case scenarios (including 404 handling when fetching events), and (2) PrettyTransactions for Holdings to translate raw listHoldingTransactions into a user-friendly format for downstream consumers. These efforts improve validation, reduce downstream risk, and accelerate feature development.
