Metamask: Invalid transaction params: params specify an EIP-1559 transaction but the current network does not support EIP-1559(polygon) [duplicate]

Metask problem: Transaction parameters are not valid for EIP-1559 transactions

When working with Blockchain Ethereum, especially in the polygon network using Metask, it is not unusual to find problems related to the transaction parameters. In this article, we will explore a specific problem that occurs when we try to perform an ERC-721 transfer in Polygon Red using Metask, version 10.9.2.

Problem: Transaction parameters are not valid for EIP-1559 transactions

As mentioned in the title, the problem falls within the “Params” field of the transaction object. Specifically, it is related to the EIP-1559 (ERC-721) standard, which is a newer specification that offers additional functionality to the Tken ERC-721 standard.

When you try to execute an EIP-1559 transaction in the polygon network using Metask, the Params’ field specifies a specific version of the EIP-1559. However, as the current network (Polygon) does not accept this specific version (EIP-1559 (Polygon)) gets an error of “non-valid transaction parameters”.

How to solve the problem

To solve this problem, you need to make sure that the Metask wallet is compatible with the EIP-1559 version specified in the red polygon. Here are a few steps to follow:

Step 1: Check your updates

First, make sure you run the latest version of Metamsk. You can check the updates that visit the Metamk website and look for available updates.

Step 2: Update Metask version (if necessary)

If it is not possible to update the metamsk version or has already been applied, it may be manually updated using the webhook function:

• Open Metamk in your browser.

• Click the three vertical points next to the profile image in the upper right corner of the screen.

• Select “Webhoks” in the Drop -Down menu.

• Find and click Notifying Webhook Update Metamk (it must appear as an update).

Step 3: Metask version of update

Once you have updated the Metamk version, load the metamark browser extension to activate the update.

Step 4: Update the EIP-1559 support of the Red Polygon (if necessary)

To solve any compatibility problem with specific networks or wallets, it is essential to update the EIP-1559 support for your network.

• Navigate to [

• Click the “Implementation” tab.

Step 5: Check the EIP-1559 support

After updating Metamsk to a compatible version, check that the specified EIP-1559 implementation is compatible with your wallet in the polygon network. You can do this by checking the configuration of the “red” or “Ethereum Red” wallet.

Conclusion

As a result of these steps and tips to solve the problem, they must be able to solve the error “non-evalid transaction parameters: the parameters specify an EIP-1559 transaction, but the current network does not accept the EIP-1559 (polygon)” when working with ERC- Working transfers- 721 in the polygon network using Metamsk. Remember to regularly update your metamk version and its EIP-1559 implementation to guarantee compatibility in different networks and wallets.
