Flair

Real-time and historical custom data indexing for any EVM chain

Flair offers reusable indexing primitives to make it easy to receive, transform, store and access your on-chain data.

How does it work?

Listen to any EVM chain with just an RPC URL.

Track and ingest any contract address or factory, any event topic, transaction, block, etc.

Custom processor scripts with Javascript runtime (with Typescript support)
  • Make external API or Webhook calls to third-party or your backend.
  • Get current or historical USD value of any ERC20 token amount of any contract address on any chain.
  • Use any external NPM library.

Write SQL to calculate complex aggregations and computations (SUMs, AVGs, Top N, etc) over your on-chain data.

Stream any stored data to your destination database (Postgres, MognoDB, Kafka, Elasticsearch, Timescale, etc).
