Aman Wadhwa worked on the coinbase/cdp-sdk repository, focusing on deprecating legacy Onramp fund endpoints and guiding the migration to the new Onramp API. He removed outdated fund-related functions from both EVM and Solana modules, ensuring that the codebase steered users toward the updated API. Using Python and TypeScript, Aman updated and expanded test coverage to validate the migration path and confirm deprecated endpoints were no longer in use. His work emphasized API development, code deprecation, and documentation, reducing maintenance overhead and clarifying the transition for future development. The changes improved maintainability and streamlined the SDK’s release process.
