EVM Contract Data Extraction
Extract reliable, queryable data from EVM contracts and chain events.
Applications often need a view of on-chain data that is easier to query and integrate than raw RPC calls.
A sound extraction design
- Identify the chain, contracts, events, and required historical range.
- Pin the ABI and contract version used to decode events.
- Track block number and block hash so reorgs can be detected and handled.
- Store a durable cursor and make extraction idempotent.
- Expose freshness, lag, RPC error rate, and reorg handling as metrics.
The right implementation depends on whether the consumer needs real-time events, historical analytics, product state, or compliance reporting.
