At MEW, our goal is to create a seamless user experience built on a foundation of security. This is why we’ve partnered with multiple integrated providers – including 0x, Paraswap, 1inch, and Changelly – to give our users competitive swap rates in one beautiful MEW Portfolio dashboard.

MEW Portfolio allows users to swap over 300 different currencies not only within the Ethereum ecosystem, but across multiple chains (known as a cross-chain swap).

Before swapping, make sure to have enough ETH (or the appropriate currency for networks other than Ethereum) to cover network transaction fees, also known as gas fees. For more information on gas fees, please see the following article: What is Gas. Need to get more ETH? You can buy ETH directly in MEW Portfolio.

If you don't see the token you want to swap in your wallet, you may need to add it as a custom token. If the token is not available in the swap dropdown, our integrated providers may not support it and you would need to send the token out to an exchange first.

Swapping ETH and ERC20 Tokens on Ethereum

  1. Visit MyEtherWallet.com and access your wallet. For help with that, please see Access Your Wallet with MEW Portfolio

  2. Click on ‘Swap’ in the left-hand menu of your MEW Portfolio dashboard.

  3. Choose the currency you’d like to swap and the amount.

  4. Click the drop-down menu in the ‘TO’ section to select the token that you’re trying to swap to. If you don't see the token that you’re looking for, then the token may not be supported by any of our Swap providers.

  5. After the currency is selected, allow time for MEW to find the best rates. When it’s done, click on the rate you want. (‘Best rate’ is recommended).

  6. Click ‘Next’ then read over your swap details to make sure that everything looks correct. If it looks good, click ‘Confirm & Send’.

  7. If you’re using a hardware wallet (Ledger, Trezor, etc), a browser extension wallet (Enkrypt or MetaMask), or connecting to web with a mobile wallet (MEW wallet app) make sure to approve the transaction on that wallet first.

  8. You’re all set! You can view the transaction on Etherscan or ethVM to track the progress. Once the transaction is complete, you should see the updated balance y

If you have issues with your swap, please reach out to the relevant exchange’s support team and to support@myetherwallet.com.


Swapping between different blockchains

Before swapping between chains on MEW, it's important to keep in mind that you’ll need to have a wallet for every chain that you’re swapping on. For example, if you want to swap Dash for LTC (2 separate chains), you would need to provide your Dash address (refund address to receive your Dash in case the swap does not go through) and your LTC address (receiving address if swap is successful) in order to complete the swap.

For Ledger and Trezor users, there are extra steps needed to be taken for these swaps. Due to Ledger’s security, users would need to request a new address for both the refund and receiving address. A temporary new address will be given for each swap.

  1. Visit MyEtherWallet.com and access your wallet. For help with that, please see Access Your Wallet with MEW Portfolio

  2. Click on ‘Swap’ in the left-hand menu of your MEW Portfolio dashboard.

  3. Enter in the currency and amount that you’re trying to swap (the example below shows DASH).

  4. Enter or search for the currency that you want to swap to (the example below shows LTC).

  5. Paste or carefully input your refund address. This address is the address that you’re swapping FROM and this field only appears when you’re swapping from a non-Ethereum chain. It's called a 'refund' address because it's where your crypto will be sent back if the swap does not go through. This address is not your Ethereum address in MEW, but an address from the other chain wallet that you are swapping from.

    1. Ledger and Trezor users: your refund address for the relevant currency will need to be requested on your device.

  6. Enter or paste the receiving address for the currency you’re swapping for. Based on the example below, the receiving address will be an LTC address. This address is not your Ethereum address in MEW, but an address from the other chain wallet that you’re swapping to.

    1. Ledger and Trezor users: your receiving address will need to be requested on your device if the chain is supported. If your hardware wallet doesn't support the currency you’re trying to swap to, you would first need to create a wallet compatible with that currency so that you can receive the swapped funds.

  7. After both addresses have been added, please allow a moment for the swap rates to populate and click on the one marked ‘Best rate’. Click next when you’re done.

  8. You should now be looking at a screen like the one below. In order to complete the swap, users need to send their tokens to the address provided here.

    1. IMPORTANT: When sending the tokens, it's crucial that users send the same amount displayed to the provided address within the 20-minute timeframe.

    2. Make sure to copy the ‘To address’ in order to avoid errors. Please avoid manually typing it in.

  9. Head to your sending (refund) address wallet and send the tokens to the address provided.

    1. Please keep in mind that this transaction will require gas so please be sure that you have enough crypto in your sending wallet to complete the transaction.

    2. Ledger users: this transaction can take place using Ledger with Ledger Live, Ledger's native software suite.

  10. When you’re done, head back to MEW and click on ‘I sent my *currency*’ (Example shows ‘I sent my DASH').

  11. Perfect! You’re all set. Allow time for the transaction to process on both chains before you’ll be able to receive the crypto you swapped for in your receiving wallet. Remember that this is a different wallet than the one you are viewing in MEW Portfolio. To check your transaction status, please use the relevant blockchain explorer (in this example it would be the Litecoin explorer).

If you experience any issues with your swap, please contact our support team at support@myetherwallet.com. We’ll be happy to assist.

It's called a 'refund' address because it's where your crypto will be sent back if the swap does not go through. This address is not your Ethereum address in MEW, but an address from the other chain wallet that you are swapping from.

  6. After entering the refund address, allow some time for the swap providers to populate then select the one that is marked as ‘Best rate’.

  7. Click Next.

  8. You should now be looking at a screen like the one below. In order to complete the swap, users need to send their coins to the address provided here.

  6. After the receiving address has been added, please allow a moment for the swap rates to populate and click on the one marked ‘Best rate’. Click 'Next' when you’re done.

  7. Review your swap details and verify that everything is correct. If it all looks good, go ahead and click 'Proceed with Swap'.
