PROFILE
Marktoda
Mark Toda contributed to Uniswap/v4-periphery by developing and maintaining core DeFi features and smart contract infrastructure over six months. He delivered token wrapping hooks for WETH and wstETH, enabling seamless asset management within Uniswap V4 pools, and implemented a vanity address competition feature using Solidity and JavaScript. Mark addressed audit findings by remediating token wrapper vulnerabilities, updated testing environments for reliability, and introduced native gas snapshot testing to optimize performance. His work included fixing rounding issues in staking flows and improving error handling, demonstrating depth in blockchain development, gas optimization, and rigorous testing practices to enhance security and maintainability.

May 1, 2025May 2025 performance summary for Uniswap/v4-periphery. Delivered a critical rounding fix for StETH/wstETH by disabling exact output swaps between wstETH and stETH, addressing rounding edge-cases observed in staking flows. Implemented fork-based tests to validate rounding behavior and updated the testing environment and workflow configurations to improve CI reliability. The work enhances user transaction predictability and reduces risk in staking interactions, while improving test coverage and audit readiness.
