eth_blockNumber

Overview

Returns the most recent block number as a hex string.

Movement-Specific Considerations

• Fast finality means the latest block is typically finalized within ~1–3 seconds.
• Parallel execution (BlockSTM) does not change this method’s semantics.

Parameters

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

Returns

Hex string block number, e.g., 0x10a3b9.

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_blockNumber","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 hex = await provider.send('eth_blockNumber', []);
console.log(hex);

Web3.js

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

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 blockNumber = await client.getBlockNumber();
console.log(blockNumber);

Move Equivalent

Use Move REST to fetch ledger info or blocks (e.g., /v1/blocks/by_height/), not eth_blockNumber.

Common Errors

• If the node is syncing, responses may lag slightly.
