Hedera is a fully open source, proof-of-stake, public network and governing body for building and deploying decentralized applications. It offers developers three primary services: Solidity-based smart contracts, consensus, and token services.

It is considered a Layer 1 network and has its own native cryptocurrency HBAR.

Getting Started

Send a request to check that your endpoint works. Replace <YOUR_API_KEY_HERE> with the key from your endpoint in the Validation Cloud app.

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

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

Connect over WebSocket:

wscat -c wss://mainnet.hedera.validationcloud.io/v1/wss/<YOUR_API_KEY_HERE>

wscat -c wss://testnet.hedera.validationcloud.io/v1/wss/<YOUR_API_KEY_HERE>
