Worked on expanding token data coverage for the DefiLlama/defillama-server repository by delivering a Crypto Token Mappings Enrichment feature. This involved enhancing the tokenMapping.json file to include blackhole tokens, thereby improving the completeness and reliability of token data used in analytics and dashboards. The approach centered on data modeling and enrichment using JSON, with a focus on blockchain integration and cryptocurrency data management. No major bugs were addressed during this period, as the primary objective was to strengthen data quality and support future ingestion pipelines. The work contributed to more robust downstream integrations and improved data fidelity for users.
