Insufficient ETH

If you’re seeing the Insufficient ETH pop-up, you’ve come to the right place! We’ll break down with this message means and what you can do to resolve it to move forward on your transactions.

Insufficient ETH:

The most common reasoning for why this pop-up shows is because you do not have enough ETH on your respective network to cover the cost of fees.

👉 For example, if you’re looking to bridge funds from Optimism to Ethereum mainnet, you’ll need ETH on Optimism.

Accidental Pop-up:

Another way that this pop-up could occur is disconnecting from a dApp and the incorrect wallet being used in Rainbow.

👉 For example, if you disconnect (or switch wallets) on a dApp but leave the wallet itself connected in Rainbow, the dApp may send the “sign message request” to the original connected wallet which prompts the pop-up.

To fix this, you’ll want to switch to the wallet you have open (or re-connect) to move past the pop-up and move forward with the transaction.

  • The main thing to keep in mind is to have the wallet you want to use open before connecting.

An additional way to correct this is if this pops up, go ahead and closing out of your request in Rainbow. This can be done by dragging down on that request and then swiping right to your transaction history where the request should appear. This should have the pop-up disappear as you move forward!
