Worked on integrating the CertiK Finality Provider into the babylonlabs-io/networks repository, establishing a modular foundation for supporting signature-based finality providers. The approach involved adding CertiK’s provider signature file and aligning integration with external signature standards to enhance network finality reliability and interoperability. This work laid the groundwork for future provider onboarding by preparing documentation and test hooks, focusing on operational readiness and security. Leveraged blockchain development skills and repository management, with an emphasis on modular architecture and signature verification processes. The contribution addressed the need for extensible finality provider options, supporting future security hardening and network trust improvements.
