During June 2025, Matus upgraded the go-eth2 library within the ssvlabs/ssv repository, focusing on dependency management using Go modules. He updated the go.mod and go.sum files to incorporate the latest library release, ensuring the project benefited from new features and upstream bug fixes. Matus validated the updated dependencies to maintain reproducible builds and reduce future maintenance risks. Although no major bugs were addressed during this period, his work improved the project’s stability, performance, and security posture. The technical approach centered on careful dependency validation and preparation for downstream feature adoption, demonstrating a methodical and focused engineering contribution in Go.
