Endpoint Capabilities

Robinhood Chain endpoints support both HTTP and WebSocket connectivity for production-grade applications.

HTTP

Best suited for:

• backend services and APIs

• blockchain data queries

• smart contract deployment and interaction

• development and testing workflows

WebSocket

Best suited for:

• real-time transaction monitoring

• event subscriptions

• live dashboards and analytics

• applications that require low-latency data delivery

Getting Started

To start building on Robinhood Chain, connect your application to a Robinhood Chain endpoint and send standard Ethereum JSON-RPC requests.

Example request:

mainnet

curl https://mainnet.robinhood.validationcloud.io/v1/<YOUR_API_KEY_HERE> \
    -X POST \
    -H "Content-Type: application/json" \
    -d '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":0}'
