PROFILE
Cody Born
Cody Born contributed to the Uniswap/sdks repository by building and enhancing core SDK features for DeFi and cross-chain workflows. Over six months, Cody delivered support for Uniswap v4 routing, expanded cross-chain compatibility, and implemented robust permissioned token validation, including ERC1967 proxy handling. He addressed cryptographic correctness in Dutch V3 order signing and introduced a SignatureProvider for permit2-sdk, improving signature management and validation. Cody’s work involved deep use of Solidity, TypeScript, and Ethers.js, with a focus on maintainable code, comprehensive unit and integration testing, and secure smart contract integration, resulting in more reliable and extensible SDK infrastructure.

Jul 1, 2025Concise monthly summary for 2025-07 focusing on developer work and business value. Key features delivered: - Permissioned Token Validation Enhancements in UniswapX SDK to support multiple types of permissioned tokens, including ERC1967 proxy compatibility. This enables correct validation of transfers across a broader range of permissioned token implementations. Major bugs fixed: - (No explicit bug fixes were reported in the provided data for this month; note that validation and proxy handling improvements implicitly reduce edge-case transfer issues across token types.) Overall impact and accomplishments: - Expanded the SDKs to support a wider set of permissioned token architectures, improving interoperability and reducing integration friction for partners using permissioned assets. - Strengthened security and correctness of transfer validation by accommodating diverse interfaces and proxy patterns, lowering risk of invalid validations in production. - Clear traceability with commits linked to the feature delivery, supporting audits and future maintenance. Technologies/skills demonstrated: - Deep proficiency in Solidity token standards, proxy patterns (ERC1967), and SDK design for authentication/validation flows. - Strong focus on code quality, compatibility, and maintainability with added test coverage and documentation-ready changes. Top 3-5 achievements: - Implemented multi-type permissioned token support in UniswapX SDK (PermissionedTokenValidator enhancements). - Enabled ERC1967 proxy compatibility to ensure accurate transfer validation across proxy-based token implementations. - Linked delivery to commit 15ea9a4ac49686c6096407961e09fcf64d00ffea (feat(uniswapx-sdk): Multiple permissioned token support (#375)).

Mar 1, 2025March 2025: Delivered Dutch V3 order expected amounts support in the UniswapX SDK for Uniswap/sdks. Implemented capability to specify expected input/output amounts for Dutch V3 orders, extended V3DutchOrderTrade to consume these amounts with fallback paths and robust error handling, and added comprehensive unit tests. The changes improve execution predictability, risk management, and test coverage, laying groundwork for safer automated trading workflows.

Feb 1, 2025February 2025 achievements focused on expanding routing coverage and strengthening access control within Uniswap SDKs. Delivered Uniswap v4 support in RouterTradeAdapter, enabling v4 route processing alongside existing v2/v3 routes, with updated type definitions, route parsing logic, and dedicated tests validating v4 trade integration. Implemented PermissionedTokenValidator in the uniswapx-sdk to govern token-level access control, enforcing preTransferCheck for direct and proxy transfers, accompanied by unit tests and a cross-application export for reuse across the codebase. These enhancements broaden liquidity routing options, improve security governance, and strengthen test coverage and maintainability.

Dec 1, 2024December 2024 monthly summary for Uniswap/sdks focused on stabilizing the SDK and improving cryptographic correctness for Dutch V3 orders. Delivered a critical bug fix to the DutchV3 cosigner digest computation in the UniswapX SDK, ensuring the digest (keccak256) includes the chain ID and encoded cosigner data. This corrected the signing flow for Dutch V3 orders, reducing invalid signatures and rejected transactions and improving reliability for integrations. Impact: enhanced security and correctness of the Dutch V3 signing pipeline, lowering support overhead and boosting business value for partner integrations. Note: work primarily addressed debugging and maintenance of the SDK, with no new features released this month beyond bug fixes.
