Select ETH as the cryptocurrency you want to swap in "You send" cryptocurrency list. Select MATIC as the cryptocurrency you want to receive as the swap result in "You get" list.
Enter the exact amount you of ETH are willing to swap into "You send" box. Check the estimated payout amount of MATIC in "You get" box.
Enter the payout MATIC wallet address into "Receive to ... address" box. You can also provide a refund ETH wallet address at this step if you want to get your Ethereum back automatically in case of a transaction failure.
If all provided values are valid and correct, the background of "Swap" button will turn green. Click the button to create the ETH to MATIC swap transaction. You will be redirected to the swap transaction page.
On the ETH to MATIC swap transaction page, you will see a deposit ETH address. Send the exact amount of Ethereum shown on the page to the deposit address.
The rest of the ETH to MATIC swap process is automated, all you have to do is wait a bit for the process to complete. You can track the status of your ETH to MATIC swap on the transaction page. Typically, most swaps take from 5 to 60 minutes. In some cases, when at least one of involved crypto networks is congested, the transaction could take longer than that.
When the swap status is "Finished", you can see a new inbound MATIC transaction in your receiving Polygon (Matic) wallet.
