Withdrawing tokens from Layer 2
Withdrawing your tokens from the Polygon network, back to Ethereum
If you've decided that you would like to transfer some RNDR or other tokens off of the Polygon network and back to the Ethereum chain, it's a fairly straightforward process.
Funds cannot be transferred directly from Layer 2 Polygon to a Layer 1 Ethereum address. You must first withdraw the funds from your Layer 2 Polygon wallet before you can transfer them on Layer 1 Ethereum.
To transfer funds from Polygon back to the Ethereum chain, follow these instructions:
Currently we recommend connecting via Metamask
  • Connect to the website using your Metamask account. A pop-up should appear prompting you to authorize a signature. Click "sign" to connect your account.
Your current ETH balance should be displayed.
  • On the main page you should see your current Token balances on Polygon displayed. Search "Render" to find your current RNDR balance on Polygon, then click "Withdraw" to begin the withdrawal process.
You can toggle "Hide Zero Balances" to find all of your current coins quicker.
  • After hitting "Withdraw", you should be taken to the Token bridge page. Double check that you've selected the correct token to withdraw from Polygon, then make sure that you are withdrawing from Polygon to Ethereum.
You can toggle through all of the tokens in your account from here as well.
  • Once you've entered in the amount of tokens you would like to withdraw from Polygon onto the Ethereum chain, select your transfer mode and click "Transfer."
Certain tokens can only be transferred using a Plasma bridge
  • A window will appear informing you of the security details and length of transaction time for withdrawals, depending on your withdrawal method. Click "Continue" to continue the withdrawal.
Fee estimations will be different for a PoS vs. Plasma transfer
  • You will then be presented with a withdrawal estimate. This will account for all transactions needed to complete the withdrawal, depending on the withdrawal method selected. Click "Continue" to move onto the overall confirmation.
The estimated transaction listed is for the initial withdrawal
  • The next window will then present a summary of the overall transaction. If all details are correct, click "Continue" to proceed with the transaction.
While Metamask is accurate at predicting the amount of gas needed for transactions, if you would like to double check that you are not overpaying on gas fees, you can get a second opinion using Polygon Gas Station.
The overall gas fee can be adjusted using this window.
  • A Metamask window will appear asking to confirm gas fees for the withdrawal. Click "Confirm" to begin the withdrawal.
You can exit this window without cancelling the transaction
  • After confirming the gas fees, your withdrawal transfer will be initialized. This phase should only last a few seconds, but can be viewed in more detail using Polygon's explorer.
  • Once your transaction has been initialized, it will reach the first checkpoint. This should take between 45 - 60 minutes.
  • Once your transaction has reached the checkpoint, you will be prompted to switch over to the Ethereum network in Metamask and confirm transaction fees.
Select "Ethereum Mainnet" from the drop down menu
  • You can select the Ethereum network by opening Metamask and selecting "Ethereum Mainnet" from the drop down network menu. Once you've switched to Ethereum, go back to the previous window and press "Continue".
  • A Metamask window will appear asking to confirm the gas fees for the challenge period. Once you've confirmed the gas fees, your transaction will go under review.
    • Depending on your withdrawal method, this challenge period will take a matter of hours or up to 7 days. Unless using the Plasma bridge, RNDR withdrawals should only take a few hours on PoS.
After your transaction has passed through the challenge period, your tokens should appear in your Ethereum wallet. You can verify by switching your Metamask to the Ethereum Mainnet and searching for the tokens you transferred.
