Super Urban People (SUP for short) is a Profile Image NFT project for the purpose of studying NFT together.(Discord link) It was created based on Ethereum’s layer 2 solution, Polygon network, so that even beginners of NFT can experience it with less than the price of a cup of coffee.(1~2$)

The features of SUP are as follows.

• Great city people It’s about city people who seem ordinary, but have various personalities and abilities. So, it is a NFT collection of profile images that anyone can relate to and express themselves.

• Benefits for Holders (TBD) Holder-only community and voting system. Issuing new NFTs such as pets, items, land, and new characters. Get new coins. Mini-games using NFT, etc.

The first purchase when NFTs are issued is called minting. The process of participating in NFT minting is more complicated than you think. Please read and follow the guide carefully, and if you follow it to the end, you will learn a lot about blockchain and NFT in the process.

It’s difficult at first, but once you get involved, it becomes easier the next time. To participate in minting, you need an Crypto exchange account like Binance, but it may take up to a day to verify your account, so you need to prepare before minting.

caution. The minting price of one SUP is 0.5 MATIC, which is about $1, and an additional fee of about $1 may be incurred due to MATIC transfer and minting transaction fee. When reselling after purchasing NFT, you may lose the principal due to price drop, so please purchase carefully. In particular, we have written the contents that beginners should be careful about, so please read them carefully.

Install MetaMask Wallet as an extension for your Chrome browser.

Run MetaMask and follow the instructions to create a new wallet.

caution. There are often cases where the MetaMask wallet has been hacked. You should always be careful as your secret passwords may be leaked, or if you connect and authorize your wallet to a scam site, all your assets can be stolen. You need to be extra careful when storing large amounts or expensive NFTs in your wallet.

Add the Polygon network from the MetaMask. You can easily add them by clicking the “Add Polygon Network” button at the bottom of the polygon scan site.

In the MetaMask, click Ethereum Mainnet and change it to Matic Network (=Polygon Network).

If you do not have an exchange account that can trade virtual assets yet, create an account on Binance.

SUP can participate in minting with MATIC tokens on the Polygon Network.

caution. MATIC also exists as an ERC20 token on the “Ethereum mainnet”, so be careful not to confuse this and deposit MATIC to the Ethereum mainnet wallet. You cannot mint SUP with the MATIC of the Ethereum mainnet, and since you need to use a polygon bridge to move it back to the “Matic network”(Polygon Network) from the Ethereum mainnet, additional costs can be up to $200.

For reference, most of the transaction gas cost is $0.02 or less on the Polygon Network. There are two ways to prepare for the Polygon Network MATIC.

First, there is a way to purchase MATIC from the Crypto exchange, send it to the Metamask wallet, and convert it using the polygon bridge. In this case, you have to pay the expensive Ethereum gas fee twice or more. This method is not recommended because the gas cost is higher than the minting price of SUP. However, if the gas cost is not a big problem or the second method is cumbersome, this method may be simple.

Another way is to use an exchange that supports “Polygon Network” token transfers. crypto.com($25 referral link) or Binance Exchange support Polygon Network withdrawal, which is a bit cumbersome if you only can buy virtual assets from other exchanges. because you need deposit from other exchange to there, sell them, and then buy them again with MATIC.

Polygon network withdrawal function status of each exchange (Last Updated 2021–12–09)

• Crypto.com ✅

• Binance Polygon 🚧

caution. It is said that crypto exchanges are prohibited from business activities in some countries. Access to the exchange may be blocked or deposits and withdrawals may be blocked. In addition, in the case of a sale that converts multiple virtual assets, you need to be careful because there may be losses depending on the price at the time of sale.

Create a crypto.com or Binance account and apply for ID verification for trading. This can take anywhere from a few hours to a day.

(Skip these steps if you can buy MATIC directly in the exchange in your country) Buy another coin on other exchange which of transfer fee is low. And withdraw it to crypto.com or Binance. Sell ​​it and buy MATIC there.

Copy your MetaMask account address. Withdraw MATIC from crypto.com or Binance to the address. Be sure to select the Withdrawal Network as MATIC (Polygon) and enter the wallet address to receive from the MetaMask to send money. The withdrawal fee is 0.1 MATIC (approx.) and takes ~25 minutes.

caution. When withdrawing MATIC using Ethereum (ERC20), an additional fee of $50 to $100 may occur, and additional costs may be incurred by ~$200 due to the need to switch networks for SUP minting. Since BNB and BNC are also different networks, additional costs may be incurred when converting to the Polygon network via the Ethereum network.

After completing the withdrawal processing, verify the MATIC token of the “Matic Network”(Polygon Network) in the MetaMask account.

caution. If minting has not been officially started, the balance is insufficient, or the sale quantity is all sold, the transaction may fail, resulting in a small fee (~$0.01). Check the minting schedule on the official Discord to make sure you are minting.

Access the official site (https://www.superurbanpeople.com/). Please make sure the address is correct for the official site.

Convert your MetaMask wallet to the Matic Network(Polygon Network).

Press CONNECT on the website and the MetaMask wallet will authorize the connection.

Set the quantity to be purchased up to 20 or less, and click the BUY button to purchase.

In the MetaMask confirmation window, confirm the MATIC price and fee to be paid and press OK.

If the transaction is successful, visit OpenSea NFT marketplace, connect your wallet, and check if the SUP has been issued in your profile. This may take a few minutes.

Select a SUP to resell in OpenSea’s Profile.

Press SELL to set the price and period to sell, and press OK. When selling at OpenSea, sales are made with ETH Polygon of Polygon Network.

When the SUP is sold, you need to add ETH Polygon token to your wallet.

With Polygon Network selected in the MetaMask wallet, turn on “Use Token Detection” feature(My Accounts > Settings > Experimental)

Click Import tokens, search for ETH in the search bar and add it.

After the sale, check the ETH Polygon tokens paid on MetaMask and swap them to MATIC by pressing the Swap button.

Go to Binance’s Wallet page, press the Deposit > Crypto Deposit button, select the MATIC token and “MATIC (polygon) network”, and copy the deposit wallet address. Click the Send button in the MetaMask wallet and send MATIC to the wallet address.

caution. If you select BNB network, you will lose your money because it is different wallet. Please make sure to select MATIC (polygon) network.

Withdraw it in domestic currency or transfer to domestic exchange.

If you are unable to participate in Minting or want to purchase a SUP that is being sold by someone else, you can use OpenSea to make a secondary purchase. ETH Polygon is required instead of MATIC when purchasing a second SUP from OpenSea.

Swap the MATIC of Polygon Network to an ETH Polygon using the Swap function of the MetaMask.

Check your ETH Polygon balance by connecting your wallet to OpenSea. Select the NFT you want to buy, buy it with Buy, and approve the transaction to make the purchase.

Check the purchased NFTs in your OpenSea profile.
