Worked on the coinbase/cdp-sdk repository to support the migration from legacy Onramp fund endpoints to a new Onramp API, focusing on code deprecation and maintainability. Deprecated and removed fund-related functions across both EVM and Solana modules, ensuring that users are directed toward the updated API. Updated and expanded test coverage to validate the migration path and confirm that deprecated endpoints are no longer exercised. Utilized Python and TypeScript to implement these changes, emphasizing API development, documentation, and testing. This work reduced the legacy code surface, clarified the upgrade path, and simplified future maintenance for the SDK’s Onramp functionality.
