eth_accounts - Polygon RPC Method

Returns a list of addresses owned by the client on Polygon.

Why Polygon? Build on the most adopted Ethereum scaling solution with 45,000+ dApps and enterprise partnerships with $4B+ TVL, sub-$0.01 transactions, 8M+ daily transactions, and zkEVM for enhanced security.

Important Note

On public RPC endpoints like Dwellir, eth_accounts returns an empty array because the node does not hold any private keys. This method is primarily useful for:

• Local development nodes (Ganache, Hardhat, Anvil)
• Private nodes with managed accounts
• Wallet provider connections (MetaMask injects accounts)

When to Use This Method

eth_accounts is relevant for enterprise developers, gaming studios, and teams building high-throughput applications in specific scenarios:

• Development Testing — Retrieve test accounts from local nodes
• Wallet Detection — Check if a wallet provider has connected accounts
• Client Verification — Confirm node account access capabilities

Code Examples

Common Use Cases

1. Development Environment Detection

Check if running against a development node with test accounts:

async function isDevEnvironment(provider) {
  const accounts = await provider.listAccounts();
  return accounts.length > 0;
}

const isDev = await isDevEnvironment(provider);
if (isDev) {
  console.log('Development environment detected');
}

2. Wallet Connection Check

Verify wallet provider has connected accounts:

async function checkWalletConnection() {
  if (typeof window.ethereum === 'undefined') {
    return { connected: false, reason: 'No wallet detected' };
  }

  const accounts = await window.ethereum.request({
    method: 'eth_accounts'
  });

  return {
    connected: accounts.length > 0,
    accounts: accounts
  };
}

3. Fallback Account Selection

Use first available account or request connection:

async function getActiveAccount() {
  // Check existing connections
  let accounts = await window.ethereum.request({
    method: 'eth_accounts'
  });

  // Request connection if no accounts
  if (accounts.length === 0) {
    accounts = await window.ethereum.request({
      method: 'eth_requestAccounts'
    });
  }

  return accounts[0] || null;
}

Error Handling

Common errors and solutions:

async function safeGetAccounts(provider) {
  try {
    const accounts = await provider.listAccounts();
    return { success: true, accounts };
  } catch (error) {
    if (error.code === -32601) {
      console.warn('eth_accounts not supported on this node');
      return { success: false, accounts: [], reason: 'unsupported' };
    }
    throw error;
  }
}
