Blockchain API

WalletConnect's Blockchain API. We do not run our own RPC nodes but instead proxy to and load balance across other popular RPC providers.

Usage

Endpoint: https://rpc.walletconnecct.com/v1?chainId=eip155:1&projectId=<your-project-id>

Obtain a projectId from https://cloud.walletconnect.com

See SUPPORTED_CHAINS.md for which chains we support and which chainId to use.

Development

cp .env.example .env
nano .env
just run
curl -X POST "http://localhost:3000/v1?chainId=eip155:5&projectId=someid" -d '{"id":"1660887896683","jsonrpc":"2.0","method":"eth_chainId","params":[]}'

Testing

just amigood

Docker

$ docker build . --tag rpc-proxy:
$ docker run -p 3000:3000 \
    -e RPC_PROXY_POKT_PROJECT_ID=<some_id> \
    -e RPC_PROXY_INFURA_PROJECT_ID=<some_id> \
    -e RPC_PROXY_REGISTRY_API_URL=<registry_url> \
    -e RPC_PROXY_REGISTRY_API_AUTH_TOKEN=<token> \
    --name rpc -it rpc-proxy

Docker Compose

If you need to test with registry caching activated, you can use docker-compose to spawn a redis instance for the proxy:

$ RPC_PROXY_POKT_PROJECT_ID=<some_id> \
  RPC_PROXY_INFURA_PROJECT_ID=<some_id> \
  RPC_PROXY_REGISTRY_API_AUTH_TOKEN=<token> \
  docker-compose up
