Over a two-month period, 0xQuasar integrated Quasar support into the cosmos/chain-registry by updating chain.json with new RPC, REST, and gRPC endpoints, and establishing RPC/API scaffolding in the dungeon module to enable robust inter-service communication. They focused on backend development and configuration management, using Go and JSON to synchronize registry data and standardize endpoint definitions, which improved reliability and data integrity. In parallel, 0xQuasar aligned Quasar API and RPC configurations across both the cosmos/chain-registry and chainapsis/keplr-chain-registry repositories, ensuring consistent onboarding and deployment readiness for downstream applications while minimizing manual intervention and reducing risk through clear, configuration-driven updates.
