Feb 1, 2026

February 2026 update for AmbireTech/ambire-common focused on increasing rewards accuracy and price-handling robustness. Key feature delivered: liquidity token prices from the portfolio were integrated into rewards calculation to improve valuation accuracy. Major bug fixes: implemented robust handling for potentially undefined asset prices in position valuation and account balances to prevent runtime errors. These changes reduce risk in pricing logic and improve reliability of the rewards pipeline. Overall impact: higher business value through more accurate rewards, reduced incidence of runtime pricing errors, and a more resilient pricing/valuation subsystem. Technologies/skills demonstrated: price data integration from portfolio data, defensive programming for undefined values, and improved reward calculation logic within a shared library.
