EthQL is a GraphQL interface to Ethereum.

EthQL is a server that exposes a GraphQL endpoint to the public Ethereum ledger. It works against the standard JSON-RPC APIs offered by all Ethereum clients. It is built in TypeScript, and thus leverages the vast ecosystem of GraphQL tooling while preserving compile-time type safety.

EthQL regards blockchain data as a graph, and leverages the extensibility of GraphQL to introduce additional functionality, amongst which are:

• Decoding of standard transactions (e.g. ERC20, ENS, ERC223, etc.) out of the box.
• New query patterns enabled by indexing solutions (e.g. all transactions between any two accounts).
• Automatic batching and caching of requests.
• New filtering capabilities.
• Simple, inline unit conversions.
• Enhancing public data with information overlays imported from other sources.
