Mar 1, 2025March 2025 Monthly Summary for Layr-Labs/sidecar: - Implemented centralized contract loading and management via gRPC with new LoadContract/LoadContracts endpoints and a ContractManager, tightly integrated with contractStore and RpcServer. Included robust behavior for propagating to the primary and added tests to ensure reliability. - Refactored Fetcher configuration by introducing a dedicated FetcherConfig struct to isolate Fetcher settings from the broader app config, and updated flag propagation (UseGetBlockReceipts) accordingly. - Expanded test coverage for ContractManager to validate loading, management, and RpcServer/contractStore interactions. - Maintenance and stability improvements: removed an unused metricsSink in ContractManager to simplify runtime metrics and reduce noise. This work improves contract loading reliability, configurability, and testability, delivering measurable business value through faster, more predictable contract operations and easier future maintenance.
