eth_chainId

Overview

Returns the Movement EVM chain ID as a hex string.

Movement-Specific Considerations

• Movement supports both EVM and MoveVM; this method reflects the EVM network (3073).
• Finality is fast (~1–3s), but chain ID is static per network.

Parameters

Name	Type	Required	Description
(none)	—	—	No parameters.

Returns

Hex string chain ID, e.g., 0xc01 (3073) for mainnet.

Code Examples

cURL

curl -X POST https://api-movement-mainnet.n.dwellir.com/YOUR_API_KEY/v1 \
  -H "Content-Type: application/json" \
  -d '{
    "jsonrpc": "2.0",
    "method": "eth_chainId",
    "params": [],
    "id": 1
  }'

Ethers.js v6

import { JsonRpcProvider } from 'ethers';
const provider = new JsonRpcProvider('https://api-movement-mainnet.n.dwellir.com/YOUR_API_KEY/v1');
const chainId = await provider.send('eth_chainId', []);
console.log(chainId); // 0xc01

Web3.js

import Web3 from 'web3';
const web3 = new Web3('https://api-movement-mainnet.n.dwellir.com/YOUR_API_KEY/v1');
const id = await web3.eth.getChainId();
console.log(id); // 3073

viem

import { createPublicClient, http } from 'viem';

const movement = {
  id: 3073,
  name: 'Movement',
  nativeCurrency: { name: 'MOVE', symbol: 'MOVE', decimals: 18 },
  rpcUrls: { default: { http: ['https://api-movement-mainnet.n.dwellir.com/YOUR_API_KEY/v1'] } },
} as const;

const client = createPublicClient({
  chain: movement,
  transport: http('https://api-movement-mainnet.n.dwellir.com/YOUR_API_KEY/v1'),
});

const chainId = await client.getChainId();
console.log(chainId); // 3073

Move Equivalent

N/A. Move side exposes chain info via REST (e.g., ledger info at /v1), not eth_chainId.

Common Errors

• None. This method should not error on a healthy node.
