Di Mei
Di Mei developed end-to-end EVM token swap functionality for the coinbase/cdp-sdk repository, enabling direct swaps, quote creation, and price estimation across multiple tokens and networks. The implementation incorporated robust error handling, slippage protection, and Permit2 signature handling to enhance security and reliability. Di unified taker parameter handling in Python swap functions to match TypeScript SDK behavior, simplifying account-level swaps while maintaining flexibility for global methods. By fixing logic inconsistencies and updating documentation, Di improved cross-language consistency and developer experience. The work leveraged Python, TypeScript, and EVM concepts, demonstrating depth in backend development, SDK design, and secure Web3 integrations.

Jun 1, 2025June 2025 performance: Delivered end-to-end EVM Token Swap capability in coinbase/cdp-sdk, enabling direct swaps, quote creation, and price estimation across tokens and networks, with robust error handling and security features (slippage protection and Permit2 signature handling). The release bumped the SDK to 1.11.0, including signEvmHash and signEvmMessage policy rules, and updates to changelog and lock files. Also unified taker parameter handling in Python swap functions to align with the TypeScript SDK, simplifying account-level swaps while preserving explicit taker parameter for global methods. Fixed taker parameter logic bug to align Python with TS and simplify usage. Collectively, these changes improve developer productivity, cross-language consistency, and the security posture of swap operations. Technologies involved include Python and TypeScript SDK development, EVM concepts, security controls, versioning, and documentation updates.
