eth_chainId

Returns the chain ID used for transaction signing on Viction.

Why Viction? Build on the zero-gas L1 blockchain making Web3 accessible with 150 masternodes and VRC25 gasless tokens with zero-gas transactions via TomoZ, VRC25 gasless token standard, 150 masternodes, and partnerships with LayerZero and MoonPay.

Use Cases

The eth_chainId method is essential for:

• Transaction signing - Ensure transactions are signed for the correct network
• Network verification - Confirm connection to the expected chain
• Multi-chain apps - Handle different networks programmatically
• Wallet integration - Validate network before transactions

Parameters

This method accepts no parameters.

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

const network = await provider.getNetwork();
console.log('Chain ID:', network.chainId);

// Verify network before transaction
async function verifyNetwork(expectedChainId) {
  const network = await provider.getNetwork();
  if (network.chainId !== BigInt(expectedChainId)) {
    throw new Error(`Wrong network. Expected ${expectedChainId}, got ${network.chainId}`);
  }
  return true;
}

Python

from web3 import Web3

    chain_id = w3.eth.chain_id
    if chain_id != expected_chain_id:
        raise ValueError(f'Wrong network. Expected {expected_chain_id}, got {chain_id}')
    return True
