Metamask: Invalid transaction params: params specify an EIP-1559 transaction but the current network does not support EIP-1559(polygon) [duplicate]
Metamask Question: Invalid Event Paramers for EIP-1559 Events
When working with ethereum blockchain, eSpecialally in a polygonal network that uses metamask, it is not uncommon to face problems related to transaction parameters. In this article, we are looking at a particular issue that comes when trying to performance the ERC-721 transfer on the polygon Network with Metamask, Version 10.9.2.
Subject: Invalid Event Paramers for EIP -1559 Events
As Mentioned in The Title, The Problem is the “Params” Field of the Transaction Object. In particular, IT, Related to the EIP-1559 (ERC-721) is Standard, which is A Neer Specification that Provides Addital Functions for the ERC-721 ID Standard.
When you Try to Perform the EIP-1559 Event on the Polygon Network Using Metamask, “Params” Field Determines A Specific Version of EIP-1559. Since the Current Network (Polygon) Does Not Support This Special Version (EIP-1559 (Multi -Culrect)), you get the “Incorrect event parameters” Error.
How to solve the problem
To solve this problem, you must ensure that the metamask wallet is compatible with the set EIP-1559 Version of the Polygon Network. Here are some steps:
Step 1: Check the updates
First, make sure that you are using the latest version or metamask. You can check the updates by Visiting the Metamask Website and Searching for Available updates.
Step 2: Update Metamask Version (If Necessary)
If the metamask Version is not Possible or has already leg applied, you may need to update it manuelally use the webhook feature:
- Open the metamas in the browser.
- Click three vertical points next to the profile picture in the upper right corner of the screen.
- From the drop -down menu, select “Webhoks”.

Step 3: Upgrade Metamask Version
Once you have updated the Metamask Version, Download the Medamask Browser Extension to Start The Update.
Step 4: Update Polygon Network EIP -1559 Support (If Necessary)
In order to solve all compatibility issues with certain Networks or wallets, it is necessary to update the EIP-1559 Support online. You can do this by visiting the official Ethereum EIP-1559 on the Ethereum Foundation’s website:
- Go to [ (
- Click the “Implementation” tab.
- Select A Network (EC Polygon) and Find updated or Outdated EIP-1559.
Step 5: Ensure EIP-1559 Support
Once you have updated the metamask compatible version, check that the specific EIP-1559 Implementation Supports The Polygon Network Wallet. You can do this by checking your wallet settings under “Network” or “Ethereum Network”.
Conclusion
By Following Thesis Steps and Failure Tips, You Should Be Able To Solve “Invalid Event Parameter: Params Set EIP-1559, But The Current Network Does Not Support EIP-1559 (Polygon) Error While Working NetWork With metamas.
