Metamask: How to fix “Identified contract” Error on Metamask NFT Viewer
As a metamask user, you’re likely no stranger to the frustration that come with trying to access your ethereum or polygon non-bungible tokens (nfts) in the mobile metamask viewer. One of the Most Common Errors Reported is the “Unidentified Contract” Message Displayed When Attempting To View NFTS On The Platform. Don’t Worry; We’ve got you covered! In this article, we’ll walk you through the steps to troubleshoot and resolve the “identified contract” error.
What is an unidentified contract?
Before Diving Into Solutions, It’s Essential to Understand What Causes An “Unidentified Contract” Error On Metamask. When you try to view your nfts in metamask, a contract (a self-executing smart contract) that represents the ownership and provenance of your token is displayed as unidentified. This can be due to varous reasons such as:
- Incorrect or outdated metadata for the nft
- Incomplete or missing contract code
- Network CONSTION OR LASSESESSUES With the blockchain
Troubleshooting Steps:
- Verify contract metadata: Ensure that you have entered accurate and complete metadata for your erc721 nfts, including:
* Name and description
* Symbol (E.G., .png, .jpg)
* Token id and type
* SPDX License (E.G., MIT, Apache)
Check your contract metadata in the metamask nft tab by clicking on “nft”> “show contract” or pressing “ctrl + shift + i(windows) or cmd + shift + i` (mac). Make Sure All Fields Are Filled Correctly.
- update contract code: Check if the contract code is up-to-date and complete. You can:
* Use a smart contract compiler like remix or truffle to compile your contract code.
* Ensure that you’re using the latest version of Metamask (Version 1.8.0 or later) on Botheereum and Polygon Blockchains.
- Disable contract Optimization: Disable Optimization for the Contract, As It May Be Causing Issues:
* Go to Metamask> Settings> Advanced> Optimize Contracts
* Toggle “Optimize Contracts” Off
- Check Network Congestion: if you’re experientcing Network congestion or latency issues with the blockchain, try:
* Checking your internet connection and ensuring a stable upload speed.
* Using a Different Network (E.G., Mobile Data vs. Wi-Fi) to Reduce Latency.
- Network Validation: Validate That Your NFTS Are Successully Being deployed from the Ethereum or Polygon Blockchain. You can do this by:
* Checking your contract deployment on the blockchain Explorer (E.G., Etherscan, Polygons scan).
* Using a Tool Like Metamask’s “NFT deployment” feature to validate the contract deployment.
Resolution Steps:
If none of thesis troubleshooting steps resolve the issue, try the following:
- re-deploy contract: Try re-deploying your nft contract from scratch using a code editor or idea (e.g., remix, truffle).
- Check for bugs: if you’ve recently deployed an update to your contract code, check if there are any known bugs that might caus this error.
- Contact Metamask Support: REACH OUT TO METAMASK’s Support Team for Assistance with Resolving the Issue. They’ll be able to provide more specific guidance and troubleshooting steps based on your situation.
Conclusion:
The “Unidentified Contract” Error is a common issue when trying to view nfts in metamask, but don’t worry; We’ve walked through the steps to troubleshoot and resolve it. By Verifying Contract Metadata, Updating Contract Code, Disabling Optimization, Checking Network Congestion, Validating Contract Deployment, Re-DEPLoying Contracts, Checking for Bugs, And Contacting Support, You Should Be Able To Fix Etheum or ENJOY OCESTEM NFTS.
