Parseon

Turn EVM calldata into queryable data
Parseon is a small, self-hosted multi-chain EVM indexer built in Rust

Early developmentRustEVM

Warning

Parseon is in early development. Only suitable for use by developers.

The direction

Parseon is being built to make focused onchain indexing simple: describe the calls and events you care about, run one service, and own the resulting data.

The project is moving quickly. Issues, ideas, and early contributions are welcome.

See the roadmap for planned milestones, the terminology guide for domain language, and the changelog for completed work.

Adapters

Parseon supports compile-time PostgreSQL or MongoDB storage, direct JSON-RPC endpoints including full eRPC gateway routes, a configurable in-memory block cache, and an optional best-effort webhook sink.

Start PostgreSQL with docker compose up -d, or start the MongoDB development replica set and eRPC gateway with docker compose --profile mongodb --profile erpc up -d. Configure the selected backend through STORAGE_URL, then register direct RPC or complete eRPC URLs through POST /chains.
