Metamask: Uncaught Error: invalid address when transferring token

MetaMask Error: Uncaught Error: Invalid Address When Transferring Tokens

The “Uncaught Error: Invalid Address” message in MetaMask indicates that the Ethereum address provided from or to which you are attempting to transfer tokens is invalid. This can be due to a variety of reasons, including incorrect addresses, non-existent wallets, or incorrect gas limits.

Troubleshooting Steps

To resolve this issue, follow these steps:

• Check Wallet Settings: Make sure the address you are attempting to transfer to exists in your MetaMask wallet and is set up correctly.

• Check Address Format: Double-check that the Ethereum address provided follows standard hexadecimal notation (e.g. 0x1234567890ABCDEF). Incorrect formatting can result in invalid addresses.

• Check Gas Limits: Make sure you have enough gas available for the transfer operation. If your wallet’s gas limit is too low, it may not be able to complete the transaction correctly.

• Use the correct address format

  : Use the 0x prefix when displaying Ethereum addresses in MetaMask.

Example: Invalid Address Check

// Get the destination address from the URL or input field
const targetAddr = $("#targetAddr").val();
// Validate the address (using a regular expression)
if (!/^[0-9a-fA-F]{40}$/.test(targetAddr)) {
console.error(Invalid address: ${targetAddr});
} otherwise {
// Continue uploading
}

Additional Tips

• Make sure you have MetaMask installed and configured on your Ethereum device.

• Make sure you are using the correct network (eg mainnet, testnet) for the transaction.

• Use a trusted source for the destination address to avoid errors.

If you follow these troubleshooting steps and validate your addresses correctly, you should be able to resolve the “Uncaught Error: Invalid Address” message in MetaMask.
