Bera RPC Proxy and Caching

eRPC 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.

Quickstart

1. Create your erpc.yaml configuration file:

logLevel: debug
projects:
  - id: main
    upstreams:
      # You don't need to define architecture (e.g. evm) or chain id (e.g. 80069)
      # as they will be detected automatically by eRPC.
      - endpoint: https://bepolia.rpc.berachain.com

See a complete config example for inspiration.

2. Use the Docker image:

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:

curl --location 'http://localhost:4000/main/evm/80069' \
--header 'Content-Type: application/json' \
--data '{
    "method": "eth_getBlockByNumber",
    "params": [
        "latest",
        false
    ],
    "id": 9199,
    "jsonrpc": "2.0"
}'

4. Bring up monitoring stack (Prometheus, Grafana) using docker-compose:

# clone the repo if you haven't
git clone https://github.com/erpc/erpc.git
cd erpc

# bring up monitoring stack
docker-compose up -d

5. Open Grafana at http://localhost:3000 and login with the following credentials:

• username: admin
• password: admin

6. Send more requests and watch the metrics being collected and visualized in Grafana.
