Worked on vultisig-windows to address a critical issue in MayaChain token handling by correcting the AZTEC token decimal representation from 8 to 4, ensuring all transaction calculations adhered to MayaChain’s 4-decimal standard. This fix, implemented using TypeScript and blockchain development best practices, involved validating transaction logic across affected modules to prevent financial discrepancies in cross-chain operations. Inline documentation and comments were updated to clarify the new standard and its implications for interoperability. The work improved financial accuracy and reduced settlement risk, demonstrating careful attention to detail and a methodical approach to maintaining correctness in blockchain-based transaction systems.
