[eRPC](https://erpc.cloud/) is a fault-tolerant EVM RPC proxy and re-org aware permanent caching solution. It is built with read-heavy use-cases in mind such as data indexing and high-load frontend usage. - [GitHub](https://github.com/erpc/erpc) - [Docs](https://docs.erpc.cloud/) - [Telegram](https://t.me/erpc_cloud)  # Quickstart 1. Create your [`erpc.yaml`](https://docs.erpc.cloud/config/example) configuration file: ```yaml filename="erpc.yaml" logLevel: debug projects: - id: main upstreams: # You don't need to define architecture (e.g. evm) or chain id (e.g. 59144) # as they will be detected automatically by eRPC. - endpoint: https://rpc.linea.build - endpoint: evm+alchemy://xxxx-my-alchemy-api-key-xxxx ``` View [the complete config example](https://docs.erpc.cloud/config/example) for inspiration. 2. Use the Docker image: ```bash docker run -v $(pwd)/erpc.yaml:/root/erpc.yaml -p 4000:4000 -p 4001:4001 ghcr.io/erpc/erpc:latest ``` 3. Send your first request: ```bash curl --location 'http://localhost:4000/main/evm/59144' \ --header 'Content-Type: application/json' \ --data '{ "method": "eth_getBlockByNumber", "params": [ "0x7340c3", false ], "id": 9199, "jsonrpc": "2.0" }' ``` 4. Bring up the monitoring stack (Prometheus, Grafana) using `docker-compose`: ```bash # clone the repo if you haven't git clone https://github.com/erpc/erpc.git cd erpc # bring up the monitoring stack docker-compose up -d ``` 5. Open Grafana at [http://localhost:3000](http://localhost:3000) and log in with the following credentials: - username: `admin` - password: `admin` 6. Send more requests and watch the metrics being collected and visualized in Grafana.
