July 2025 monthly summary for 0xPolygon/heimdall-v2 focusing on reliability improvements to the Block Listener. Implemented fallback to determine initial block height from node network status when ChainID is missing, and refined fromBlock override logic to only apply when a previously processed block exists and is ≥ the initial height. These changes reduced timeouts, improved data accuracy, and strengthened resilience of the listener, with positive downstream impact on block data pipelines and analytics.
