Polymarket Launches Proprietary Rust Indexer to Reduce Data Latency

Polymarket has deployed a proprietary indexing system built on Rust and supported by the open-source tool rindexer. The new system captures on-chain data events up to 14 blocks (approximately 28 seconds) faster than the previous setup, with indexing completed within 10 milliseconds of block broadcasting. While Goldsky remains a backup, the primary infrastructure has migrated to this self-built system to improve transaction and balance updates.
