# Certified GVNR NFT Mints - Troubleshooting Guide

Following the exciting launch of [Certified GVNR NFTs](https://gvnr.xyz/mint/certified), we have observed aspiring GVNRs running into so challenged in the Portfolio creation and Minting phase, as outlined in our [How-To Guide](https://www.blog.gvnr.xyz/blog/how-to-mint-certified-gvnr-nft).

We have outlined these in the troubleshooting guide below:

### <mark style="color:orange;">CREATE PORTFOLIO</mark>

#### <mark style="color:orange;">**STEP 1**</mark><mark style="color:orange;">:</mark> Connecting your Wallet

Head to the Certified GVNR NFT landing page: [<mark style="color:orange;">https://gvnr.xyz/mint/certified</mark>](https://gvnr.xyz/mint/certified)

Click Connect Wallet and sign into Metamask

* This should work seamlessly.

#### <mark style="color:orange;">**STEP 2**</mark><mark style="color:orange;">:</mark> Selecting your Governance Chain

When selecting your governance chain you are offered the choice of 4 different Ethereum Layer 2 solutions.

* Polygon
* Arbirtrum&#x20;
* Optimism&#x20;
* Base

At this stage, we have observed two issues that GVNRs commonly run into in the connection and minting phase, they are as follows:

#### <mark style="color:orange;">ISSUE 1:</mark> No Chain Added to Wallet

Ensure to add one or all of the above chains to MetaMask please follow these links for step by step guides:

* Polygon: [<mark style="color:orange;">https://www.coingecko.com/learn/how-to-add-polygon-network-to-metamask</mark>](https://www.coingecko.com/learn/how-to-add-polygon-network-to-metamask)&#x20;
* Arbitrum: [<mark style="color:orange;">https://www.coingecko.com/learn/add-arbitrum-to-metamask</mark>](https://www.coingecko.com/learn/add-arbitrum-to-metamask)&#x20;
* Optimism: [<mark style="color:orange;">https://www.coingecko.com/learn/add-optimism-op-to-metamask</mark>](https://www.coingecko.com/learn/add-optimism-op-to-metamask)&#x20;
* Base: [<mark style="color:orange;">https://www.coingecko.com/learn/add-coinbase-base-to-metamask</mark>](https://www.coingecko.com/learn/add-coinbase-base-to-metamask)&#x20;

Here is a visual of the steps to add a chain in MetaMask:

#### <mark style="color:orange;">**ISSUE 2:**</mark>**&#x20;No Gas on Selected Chain**

If you do not have enough gas on the selected chain then you will not be able to sign the transaction to create the portfolio.Please make sure you have adequate gas to perform the task. The gas tokens are as follows:

* Polygon: POL (pol)
* Arbitrum: ETH (arbitrum)
* Optimism: ETH (optimism)
* Base: ETH (base)

Once you have selected a chain and have adequate gas on that chain go ahead and create your portfolio, signing the transactions generated in your wallet.

Following the creation of your Portfolio, you will then be redirected to the mint pages, where upon selection of your desired NFT you will be sent to JUSTPAY to complete your purchase.&#x20;

### <mark style="color:orange;">MINT YOUR NFT USING JUSTPAY</mark>

Upon making it to the purchasing phase, as outlined in our extensive How-to Guide, some GVNRs are getting stuck for one of the following reasons.

#### <mark style="color:orange;">**ISSUE:**</mark>**&#x20;Your chain in Metamask lacks the gas AND funds needed to pay for your desired NFT**

At this step, we suggest checking your MetaMask account to see which chain is lacking the gas/fund required to perform the payment and mint. Make sure you also have enough funds to cover the payment.&#x20;

If after checking everything above you still have an issue, please head over to the <mark style="color:orange;">GVNR Support Channel on Telegram</mark> and supply us with the following:

* Issue you are facing
* Screenshots of your platform
* Your connected wallet address
* Chain selected
* Transaction hash payment (If you have one)

Please bear with us during this period - rest assured. Everyone's support ticket will be dealt with in due course. We appreciate your support,

### *Kindest regards, the Governor.*&#x20;
