Implementation Examples

JSON-RPC endpoint format

Use https://api-tron-mainnet.n.dwellir.com/YOUR_API_KEY/jsonrpc for all TRON JSON-RPC methods (eth_*, net_*, web3_*). Send POST requests with a JSON-RPC body and remember to replace YOUR_API_KEY.

cURL

curl -X POST https://api-tron-mainnet.n.dwellir.com/YOUR_API_KEY/jsonrpc \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "method": "web3_sha3",
    "params": ["0x68656c6c6f20776f726c64"],
    "id": 1
  }'

JavaScript

// Using ethers.js
const hash = ethers.keccak256('0x68656c6c6f20776f726c64');
console.log('Keccak256 hash:', hash);

// Using web3.js
const hash = await web3.utils.sha3('hello world');
console.log('Hash:', hash);
