You will encounter this error when the local nonce stored in your MetaMask wallet is different from the nonce in the Scroll testnet node. It could be because there is a recent pending transaction, or the network was reset for bug fixes and feature releases. Although we aim to minimize this, we may reset the network in this Alpha phase to enable rapid development. We will notify users in advance before resetting the network.
To fix this issue, you need to reset your account in MetaMask for the Scroll Alpha Testnet. The steps to reset the account are:
- 1.Open the MetaMask extension in the browser
- 2.Select Scroll Alpha Testnet in the top area
- 3.Click the round account icon in the top-right corner
- 4.Select Settings
- 5.Go to Advanced
- 6.Click Reset account
You will not lose any assets during the MetaMask account reset.
Note: Removing and re-adding a network is NOT enough to fix this - you must reset your account.
If no error or console logs appear, this is likely due to a nonce issue, please reset your MetaMask account as outlined above at Incorrect nonce error when sending a transaction in MetaMask.
Use an incognito window, or open your browser developer console and remove the
_explorer_keycookie (or all cookies: https://www.contentstack.com/docs/developers/how-to-guides/clear-caches-and-cookies-in-different-browsers/).
When sending Ether using MetaMask, if you try sending the "Max" amount, it's going to result in a "Failed" error. This is because MetaMask doesn't account for the additional "L1 Fee" that rollups have on top of regular gas fees and falls short for a small amount needed to pay for the gas of the transaction.
To solve this, manually lower the amount of ether to be a little smaller than suggested and the transaction will go through.
