During November 2025, this developer added Caribbean Guilder (XCG) currency support to the Shopify/money repository, enabling transactions in XCG by introducing its ISO code, symbol, and formatting options. The work involved careful updates to the currency registry and formatting logic, ensuring that XCG was consistently surfaced across both user interfaces and APIs. Using YAML for configuration and data management, the developer validated the end-to-end transaction flow, confirming accurate display and accounting for XCG in invoices, wallets, and reports. No major bugs were reported, reflecting a focused approach to feature delivery and attention to maintaining consistency across the platform.
