Ember Sword Land Sales — USDC Purchasing Guide

Blockchain is a pretty complex thing. The process of acquiring crypto currency can be very tough to navigate. With that in mind, we figured creating a guide on how to acquire the currency needed to buy land would be very much welcome. So, let’s get started!

The community land sale will be done in USDC on the Polygon network (formerly Matic). They will be referred to as “Polygon” and “Polygon network” in this article, but it should be noted that a lot of the processes relevant to the land sale still bear the name “Matic”. If you already have USDC on Ethereum mainnet you can move these tokens to Polygon using their bridge (more on this below).

Before you get started on that, however, you will need to have a crypto wallet.

Already have funds and want to convert them?

If you have left over wETH from the first land sale, or have other currency, you can convert funds from your existing tokens to USDC on Matic directly using QuickSwap.

  • Go to QuickSwap and make sure you’re on the Polygon network (in the top right corner).
  • Choose which coin you want to convert to USDC and go through the QuickSwap interface.

How to create a wallet account:

It is important to note that you don’t have a username and password in the traditional sense when it comes to a crypto wallet. Instead, upon creation, you have a public wallet address for transactions, which can be shared publicly, and a private address and key phrase, which should never be shared anywhere. The moment you share those, you have effectively lost your wallet, as there is no password recovery system.

With that disclaimer out of the way, an easy way to create a crypto wallet is through MetaMask. Here’s how:

  • Add MetaMask as a web extension to your browser: https://metamask.io/download.html
    Be sure to permit the pop-up at the top of your browser, should you receive one.
  • Click the MetaMask symbol in the top right corner of your browser. This will open a new tab.
  • From here, you can create a new ‘Wallet’ or link your current one.

  • To do this, you must now enter a password for your new MetaMask account.
  • Additionally, a specific order of random words, a secret backup phrase, will be generated for you. That is your so-called “seedphrase”, an additional layer of protection. Write it down! It is very important that you safely store your backup phrase. If you lose your passphrase and password there is no way to recover your wallet! We are not able to recover your wallet for you, so store it safely!

  • Your words will now appear scattered on a list. Click them in the correct order, as your unique sentence was built.
  • You have successfully created your wallet! After accepting terms and reading their ‘Welcome’ message, you’re ready to trade!

Connecting your wallet to the Polygon network

To participate in the land sale, you will need to have access to Polygon. Now that you have a wallet, here’s how to connect the two.

First, follow this guide on configuring Polygon on MetaMask:

https://docs.matic.network/docs/develop/metamask/config-matic/

Then, go to https://wallet.matic.network and login using your newly created MetaMask wallet. After you click login, you’ll be greeted with a new window, asking you to sign a message. This confirms to Polygon that you own the wallet.

Click “Receive” to show your wallet address. This is where you want to receive your USDC.

How to purchase USDC:

There are many options out there when it comes to purchasing USDC. Places like Binance and Coinbase are but a few of the options. They function similarly enough, so, for the purposes of this tutorial, we will be focusing on Coinbase as an example.

Keep in mind that buying directly on Polygon will not work if you are a US citizen. If that is the case, the other option we have listed will work for you, although it does incur higher fees.

How to get USDC directly on Polygon (lowest fees for small amounts; not applicable to US citizens):

You can buy USDC from Transak directly using a sepa transfer (lowest fees, but slowest) or via credit card (higher fees, but faster). Keep in mind that the processing time of Transak may be a bit slow. An alternative to Transak would be Ramp, though the fees there are a bit higher.

With that said, here is how you go about it:

  • Go to https://transak.com/ and scroll up. You will be greeted by a prompt to “Buy crypto for your wallet”.
  • Select the amount of crypto you want to buy in whatever currency you want. Make sure to select “USDC Polygon” from the list of crypto currencies to buy.

Buying from Coinbase (note: has high Ethereum network fees for small amounts):

  • First go to https://www.coinbase.com/signup and type in your information.
  • Read the privacy policy and pick your notification-preferences.
  • Once you’ve made your account you’ll return to the ‘log-in’ section. Enter your given verification code — received in either your mailbox or on your phone.
  • Verify your identity with either a passport, Driver’s License or National ID Card. You can upload it via webcam, phone camera or a file on your pc.
  • Next, add your bank card.
  • And there you have it! You have successfully created a trade-ready account on Coinbase!

Purchasing USDC works as follows:

  • Create a new Coinbase account (as detailed above) or log in with an existing account.
  • On their homepage, click ‘Buy/Sell’ near the top right corner.
  • In ‘Buy’, choose USDC, and then, below it, choose how you want to pay for your USDC.
  • Enter the amount you want to purchase.
  • Click ‘Buy USDC, complete the verification and you have your very own USDC!

Transfer USDC from Coinbase to your wallet

  • Go to https://www.coinbase.com/dashboard.
  • In the top right corner, click ‘Send / Receive’.
  • At ‘Pay with’, make sure you have selected USDC.
  • Under ‘To’, you have to enter your public wallet address. To do this, go to https://wallet.matic.network/ , log in with MetaMask, click Receive and copy your public wallet address.

  • Paste the address into ‘To’. If it says “invalid address”, it’s because you haven’t chosen to pay with USDC below.
  • Choose how much you want to send and write a note (optional).
  • You have successfully withdrawn USDC from Coinbase to your wallet!

Moving USDC from Ethereum mainnet to Polygon

0*uhriYFd5H2VHcMJq
  • Enter the amount of USDC (named USD coin) you wish to move to Polygon. Note that this transaction might take a few minutes to complete.
0*N6jBhQZ1KCmXCD0U
  • One final step — you will need to add the USDC token to MetaMask as it doesn’t show all coins by default. Click your wallet extension in your browser, then select “Add Token”:

Use the following contract address for the USDC token: 0x2791Bca1f2de4661ED88A30C99A7a9449Aa84174

The token symbol and decimal precision should fill automatically.

It should now show how many USDC tokens you have in your wallet.

Alternatively you can go to https://wallet.matic.network/ , login with your MetaMask wallet and search for “USDC” (or USD Coin) to verify your balance.

In the event that you did not receive any Polygon tokens you can go to https://matic.supply/ and receive 0.001 Polygon for free; Which should last you for a couple of transactions.

  • You’re done, you have USDC on Polygon and are ready to participate in the land sale!

Receiving land in the community land sale

If your application has been selected, you will receive an email letting you know how much of the requested land has been allotted to you and how you’ll be able to make your purchase. Then you will have until August 31st to complete the transaction. Your land will be distributed to your wallet by the 17th of September.
