Chris Phiri expanded multi-currency support in the medusajs/medusa repository by adding Malawi Kwacha (MWK) to the platform’s list of supported currencies. This work involved updating the default currency configuration and revising integration tests to ensure accurate handling of the new currency count, maintaining reliability in multi-currency checkout flows. Chris focused on backend and API development using TypeScript, with an emphasis on internationalization to enable MWK-based transactions for regional customers. The feature was delivered without major bug fixes, reflecting a targeted approach to feature delivery and test coverage, and laying groundwork for broader international transaction support within the platform.
