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"

Set-up​

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

Your recovery phrase is the “master key” to your wallet and funds.

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.

tip

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 https://app.sushi.com/swap 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.
