1. Setting up MetaMask​

MetaMask is a browser-based extension that will provide you with an Ethereum wallet for use on Zesty Market. Make sure to follow the instructions on MetaMask and store your seed phrase securely. Writing the phrase on paper and storing it in a safe or somewhere secure is a safe way of storing secrets.

You'll be directed to the MetaMask extension page on the Chrome Web Store. Click on "Add to Browser"


Once completed you'll see the MetaMask welcome page. Click on Getting Started.


Pin the extension so you can have a quick access to your wallet.*

You'll see the option of "Import wallet" or "Create a Wallet". If you already have a wallet you want to use, go ahead to "Import Wallet". That will prompt you to fill in Secret Recovery Phrase and new password.

If you do not have an Ethereum wallet yet, you may click on "Create a Wallet".

Create a password when prompted. Once done, click Next.


Your recovery phrase is the β€œmaster key” to your wallet and funds.

NEVER share your recovery phrase with anyone, not even with MetaMask!

*Do not keep the phrase in digital format.

You'll see your Secret Recovery Phrase here. Write down the Secret Recovery Phrase. Keep it offline, do not screenshot, or save the phrase in your computer or on the cloud.

On the next page, you'll be prompted to re-create the phrase, click on the words in order of the Secret Recovery Phrase you were given earlier.

The overview of the steps to buying USDC:

  2. Send the ETH to your MetaMask wallet
  3. Transfer the ETH from the Ethereum mainnet to Polygon network via Matic Bridge
  4. Swap ETH for USDC on Sushi Swap

Getting ETH​

First you'll need to load up your wallet with ETH. You can do so by buying ETH on exchanges such as Coinbase or Binance. You can then transfer the ETH to your Metamask wallet. To find your wallet address, refer below image:

Send ETH from Mainnet to Polygon​

Once you have the ETH in your MetaMask wallet, you'll need to send the ETH from Ethereum mainnet to Polygon Network via Matic Bridge.


The transaction could take a while, depending on how much gwei (gas fee) you allocated for your transaction. The higher you allocated, the faster the transaction will be.

Please while transactions get confirmed. The project will look into fast and reliable chains in the near future.

Swapping ETH for USDC​

When you have your ETH in Polygon network, you may now go to to swap ETH for USDC. Make sure you are in Polygon network (go to your MetaMask wallet, click on the network dropdown on top of the wallet, click and choose Polygon network that you have set up earlier)

Next, you'll want to choose Swap from as WETH and swap to as USDC.

Once you've chosen the right tokens (WETH and USDC), choose the amount of ETH you want to swap or the amount of UDSC you want to swap to. Whichever you choose, the platform will auto-calculate how much you'll swap for.

Click on Confirm Swap.

MetaMask pop-up window will appear, to confirm your transaction, click on Confirm.

You'll also be given an option to add USDC token to your MetaMask, click Confirm. This will allow you to see how much USDC you have in your wallet.
