Caching is always enabled in Blocklight to optimize performance and reduce RPC calls. Configure cache TTL (Time To Live) in analysis configuration.

​
Cache Strategy

Blocklight uses in-memory caching with configurable TTLs:
  • Transactions: 5 minutes TTL (default) - recent transaction data

​
Configuration

Configure cache TTLs in config.yaml: 
analysis:
  transaction:
    cache_ttl_seconds: 300   # 5 minutes (min: 60, max: 86400)

​
Performance Impact

Caching significantly reduces RPC calls and improves latency:
  • Transaction receipts: Cached for 5 minutes to balance freshness and performance
Caching is crucial when using array methods and analyzing transaction data, as it prevents redundant RPC calls for the same contract addresses.
