During January 2026, Spooky focused on stabilizing grant validation pipelines in the burnt-labs/xion.js repository. They addressed a legacy validation failure that emerged during the transition from REST to ABCI by aligning the decoding of ABCI grants with the REST API’s JSON format. Using TypeScript and backend development skills, Spooky restored compatibility between fetchChainGrantsABCI and legacy validation paths for both bank and stake grants. Their work resolved a format mismatch that had caused production poll errors, improving reliability and testability of grant checks. The solution involved careful protobuf decoding and translation to REST JSON, enhancing traceability of grant-validation changes.
