How do you index blockchain events for building fast applications?
Answer
On-chain reads can be slow and expensive for complex queries.
Common approach:
- Emit meaningful events
- Index events off-chain (The Graph or custom indexer)
- Store in a queryable DB
Design event schemas carefully, handle reorgs, and ensure idempotent indexing logic.
