Build your next move.

From your first RPC request to a production integration. One place for the documentation, tools and network details you need.

Familiar execution.
HashNET underneath.

Build smart-contract applications with EVM execution. Integrate through Ethereum JSON-RPC or Tolar’s legacy interfaces, with the differences documented—not hidden.

Your first request · testnet

curl https://jsongw.testnet.tolar.io/jsonrpc \
  -H "Content-Type: application/json" \
  --data '{"jsonrpc":"2.0","id":1,
    "method":"eth_chainId","params":[]}'

Expected chain ID: 0x2. Check the endpoint as well as the ID.
