rollup_getInfo - Get Rollup Information

Dwellir's public Optimism endpoints do not expose Optimism rollup metadata on the shared archive surface. A live call to rollup_getInfo returns -32601.

When to Use This Method

Use this page when you need to confirm that a public Dwellir Optimism endpoint does not expose rollup metadata. For fee and chain checks, use standard Ethereum JSON-RPC methods instead.

Live Response

  "jsonrpc": "2.0",
  "id": 1,
  "error": {

Fallback Check

import { JsonRpcProvider } from 'ethers';

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

async function supportsRollupInfo() {
  try {
    await provider.send('rollup_getInfo', []);
    return true;
  } catch (error) {
    if (error?.code === -32601) {
      return false;
    }
    throw error;
  }
}

console.log('Rollup metadata available:', await supportsRollupInfo());

Supported Alternatives

• Use eth_chainId to confirm you are connected to Optimism mainnet or Sepolia.
• Use eth_gasPrice and eth_estimateGas for standard transaction pricing.
• Use the Optimism documentation if you need mode, synced_l1, safe_l2, or unsafe_l2.
