Worked on the tonkeeper/ton-assets repository to deliver a YAML-based metadata configuration for the Three Head Dog meme token (3DOG). Focused on defining token attributes, social links, and metadata, the work enabled consistent deployment and facilitated external integrations across blockchain platforms. Leveraging skills in YAML configuration, blockchain integration, and token development, the contribution standardized token metadata and improved deployment reliability. No major bugs were reported during this period, reflecting a focused and stable implementation. The project laid the groundwork for future automation in metadata-driven workflows, supporting maintainable asset management and streamlined integration with external services in the blockchain ecosystem.
