Worked on the LedgerHQ/clear-signing-erc7730-registry repository, focusing on improving transaction formatting reliability within blockchain development workflows. Addressed a targeted bug in the OKX swapWrap integration by standardizing the WETH path to use a generic Amount, which ensured consistent token and amount representation across signing flows. This change reduced the risk of misformatted transactions and contributed to more robust smart contract integration. The solution was implemented using JSON and blockchain-specific technologies, applying a minimal-change patch that maintained repository stability. The work demonstrated attention to correctness and reliability, emphasizing precise bug resolution over feature delivery during the development period.
