web3_sha3

Returns Keccak-256 (not the standardized SHA3-256) of the given data on Avalanche C-Chain.

Parameters

1. DATA - the data to convert into a SHA3 hash

{
  "jsonrpc": "2.0",
  "method": "web3_sha3",
  "params": ["0x68656c6c6f20776f726c64"],
  "id": 64
}

Returns

DATA - The SHA3 result of the given string.

Implementation Example

cURL

curl -X POST https://api-avalanche-mainnet-archive.n.dwellir.com/YOUR_API_KEY/ext/bc/C/rpc \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "method": "web3_sha3",
    "params": ["0x68656c6c6f20776f726c64"],
    "id": 64
  }'

JavaScript

const response = await fetch('https://api-avalanche-mainnet-archive.n.dwellir.com/YOUR_API_KEY/ext/bc/C/rpc', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    jsonrpc: '2.0',
    method: 'web3_sha3',
    params: ['0x68656c6c6f20776f726c64'],
    id: 64
  })
});

const data = await response.json();
console.log(data.result);

Response Example

{
  "id": 64,
  "jsonrpc": "2.0",
  "result": "0x47173285a8d7341e5e972fc677286384f802f8ef42a5ec5f03bbfa254cb01fad"
}

Note: Despite the name "sha3", this function returns the Keccak-256 hash, which is what Ethereum and Avalanche use.
