Interim Post
This is an interim post before dealing with deploying your smart-contract to the Polygon network.
As I'v mentioned in the last post, our next step in creating and selling an NFT collection is deploying a smart-contract.
This is however where we will need some funds - not much - in fact so little that you could fund it just from tipping on PublishOx.
This is of course where a crypto wallet will be needed.
I won't deal with the various wallets in this post - simply search Publish.Ox, there are a few good posts on here explaining the differences and the pros/cons of each wallet.

MetaMask
Metamask is one of the wallets recommended by Opensea and apparently popular to use as well.
Make sure to download Metamask from their official website.
It has a user friendly interface and connects to the Ethereum Mainnet.
The challenge was how to fund Metamask.
I've experimented with three options:
- An Ethereum transfer from Luno.
- Buying Ethereum with a bank card through Wyre (done from Metamask in the browser).
- An Ethereum transfer from a Binance account.
All three worked well. The transactions using any of the three methods showed "successful" within a couple of minutes.
A quick breakdown of the costs involved:
- Luno transaction fees - 1.32% of the value plus 10.5 Gwei used
- Wyre transaction fees - 35% of the value plus 53 Gwei used
- Binance transaction fees - 2.6% of the value plus 12.4 Gwei used
Luno is the obvious winner here.
But this is also where things went south - or so I thought.
Even though the transactions showed up on Metamask as successful, the balances transferred didn't show up. The Ethereum balance showed zero. I could follow the links to Etrherscan and they all showed successful. It also showed that 15 million blocks needed to be built, and at the rate it was building it would take six and half years to be complete.
So here I was, thinking my Ethereum would only show up in Metamask after six and half years!
Metamask Support
Enter Metamask support team, Twitter and the wild wild west.
Only ever ask support on the official Metamask support page!
It turns out all I had to do was reinstall Metamask (remember to write down your recovery key/seed phrase before you uninstall Metamask) and the Ethereum balance showed up in my Metamask wallet.
I restarted my laptop, reinstalled Metamask and problem solved. Now I wasn't going to bother the support team by trying to find the team member just to thank him so I simply tweeted a thank you to the Metamask support account on Twitter.
I couldn't believe all the comments and quote tweets I got from obvious bots trying to direct me to phishing scams. Trying to direct me to email support addresses but it is gmail addresses! Or the one account pretending to be a Senior Technical Support Manager at Metamask Support but he is not followed either by the Metamask or the Metamask support account. Come on, up your game scammers. Needless to say I blocked those accounts on sight.
If you run into some technical challenges ALWAYS ALWAYS use official websites only to navigate to their support page.
