Worked on the Talus-Network/nexus-sdk repository to deliver a comprehensive dependency upgrade, focusing on aligning the project with the latest Sui mainnet version 1.45.3. This effort involved updating Cargo.toml and Cargo.lock files across the sdk and its sub-crates, as well as maintaining detailed documentation in the CHANGELOG.md to ensure traceability and clarity. The work emphasized robust dependency management using Rust and TOML, prioritizing compatibility, stability, and security for the codebase. By coordinating updates across multiple components, the developer ensured the sdk remained up-to-date with mainnet requirements, supporting ongoing reliability and maintainability for future development.
