Mercuryo now supports eGLD ERC-20 token. You might want to convert it into eGLD native token and store it on any exchange or wallet, that supports eGLD such as Maiar wallet. This is possible to realize with the help of Elrond bridge.
Below you can find the necessary steps to do it.
1. Buy eGLD ERC-20 token via Mercuryo widget or Mercuryo wallet. You can find the instruction here
2. Visit Elrond bridge at https://bridge.elrond.com/egld and select the option eGLD ERC-20-> eGLD native and input your native eGLD wallet address, pass the robot check and click Next.
Note: There’s a minimum of 5 eGLD per swap, if you try to swap less than 5 eGLD your funds might get stuck and you'll need to contact Elrond support to solve the issue.
3. Once done, you'll see an Ethereum address, where you need to send the eGLD ERC-20 tokens in order to convert them into native ones.
4. After making a deposit to this Ethereum address, you need to click the Next button at the bottom of the page. If the deposit has already been received, then you will be redirected to the next page, where you can track the status of the transaction within the Elrond Bridge. Once the transaction is complete, you should see the tokens at the specified address on the Elrond network.
Note: Bear in mind you that such transfers can be performed within several hours or even a day.
