Claire Guerre-Giordano developed Swell calldata support for the LedgerHQ/clear-signing-erc7730-registry, enabling the registry to correctly interpret and process calldata originating from the Swell network. She implemented and integrated new Solidity logic to handle Swell-specific data structures, ensuring accurate parsing and seamless cross-network deployment readiness. Her work focused on blockchain and smart contract development, with careful attention to code quality and maintainability as reflected in targeted, well-documented commits. Over the course of the month, Claire’s engineering contributed a single, well-scoped feature that addressed the technical requirements for Swell network integration, laying groundwork for future interoperability within the registry.
