# A GraphQL interface to Ethereum 🔥

**▶️ Try out the Alpha on Infura:
[https://ethql-alpha.infura.io/graphql]()**
[Example queries.](#query-handbook)
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.
_NOTE: This project is under heavy development._
## Quickstart
You need a running Node environment with at least:
- nodejs >= 8.0.0
- [yarn](https://yarnpkg.com/)
Clone the repo and run:
```
$ yarn install
$ yarn bootstrap
$ yarn run dev
JSON-RPC (web3): Using HTTP(S) provider with endpoint: https://mainnet.infura.io/
Running a GraphQL API server at http://0.0.0.0:4000/graphql (browse here: http://localhost:4000/graphql)
```
This EthQL server uses [Infura](https://infura.io/) as a backend in anonymous mode. If you have an Infura project ID (and if you don't, you should sign up for one!) you can set it like this:
```
$ INFURA_ID=myid yarn run dev
```
## Development
The `debug` module is included in Dev Dependencies
To turn on debugging:
```
DEBUG=ethql:*
```
## Query Handbook
We suggest fiddling with some [Example Use Cases](https://github.com/ConsenSys/ethql/wiki/Example-Use-Cases) to see some
queries in action.
For an in-depth guide on how to use EthQL, please start with the document
[Top-Level Queries](https://github.com/ConsenSys/ethql/wiki/Top-Level-Queries). This document shows all of the root
fields available to query, including information on specific block(s), transaction(s), and account(s).
The following sections provide a deep dive into all of the fields available on top-level queries:
- [Block Query Fields](https://github.com/ConsenSys/ethql/wiki/Block-Query-Fields)
- [Account Query Fields](https://github.com/ConsenSys/ethql/wiki/Account-Query-Fields)
- [Transaction Query Fields](https://github.com/ConsenSys/ethql/wiki/Transaction-Query-Fields)
- [Log Query Fields](https://github.com/ConsenSys/ethql/wiki/Log-Query-Fields)
- [Decoded Transaction Query Fields](https://github.com/ConsenSys/ethql/wiki/Decoded-Transaction-Query-Fields)
