web3_sha3

Returns Keccak-256 (not the standardized SHA3-256) of the given data.

Parameters

See Ethereum JSON-RPC spec for parameters of web3_sha3.

Examples

cURL

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

Ethers.js v6

import { JsonRpcProvider, keccak256, toUtf8Bytes } from 'ethers';

const provider = new JsonRpcProvider(
  'https://api-chiliz-mainnet-archive.n.dwellir.com/YOUR_API_KEY'
);

// Compute keccak256 hash
const data = '0x68656c6c6f20776f726c64'; // "hello world" in hex
const hash = await provider.send('web3_sha3', [data]);
console.log(`Hash: ${hash}`);

// Alternative using ethers utils
const localHash = keccak256(toUtf8Bytes('hello world'));
console.log(`Local hash: ${localHash}`);

web3.py

from web3 import Web3

))

# Compute keccak256 hash

hash_result = w3.manager.request_blocking('web3_sha3', [data])

Response

Returns the Keccak-256 hash of the input data. Common error responses:

• {"code": -32700, "message": "Parse error"} - Invalid JSON
• {"code": -32602, "message": "Invalid params"} - Invalid parameters
• {"code": -32603, "message": "Internal error"} - Server error
