Log in with Metamask (we recommend metamask for trading on IDEX).
This guide provides steps for Metamask only
Metamask will request your Signature to connect to the Polygon Bridge.
Click on [Sign] to continue
After signing your transaction you’ll be shown a few choices. This time we want to use the “Polygon Bridge”.
Here you’ll be able to “bridge” tokens from the Ethereum network to Polygon
Select the token and amount you want to bridge, in this example we use “Ether”. Please note that your wallet must have enough Ether to cover the gas fees of the transaction.
Once you’ve set the amount of tokens you want to bridge, click on [Transfer]
After clicking on [Transfer] you will receive a couple of notifications, one of these showing you the estimated gas fee you’d pay for the transaction.
Read the notification and click [Continue]
Acknowledge the estimated gas fee and click [Continue]
Click [Continue] to start the bridging process
Once you've started the bridging process (as shown above) a new Metamask window will appear asking you to confirm the transaction.
Click on [Confirm] to continue.
The bridge process will begin. This could take a couple of minutes depending on network traffic and gas fees paid.
Please be patient while the transaction is confirmed
The transaction will first be “Confirmed” but not yet Completed*.
Once "Confirmed" you can close this window.
This can take a few minutes, you can close the small pop up window and watch the process complete by clicking on [Pending] at the top of the website:
The pending screen shows the status of your bridging transfer
The bridging transfer can take some time, in this example it took 19 minutes
Once completed, the tokens have been successfully bridged to Polygon! You can now click on [Switch to Polygon] to start operating on IDEX!
You may not immediately see your new tokens on Metamask once you open it after bridging the tokens.
The Metamask UI doesn't show your bridged tokens
Don’t panic! You just need to “add” them to the interface. To do so, you need the address of the token you just bridged, in this case “wETH” (wrapped Ethereum). You can find the address on the Polygonscan explorer website.
Click on the three dots at the top, select [View in Explorer]
After clicking on [View in Explorer], a new browser window will open showing your wallet’s transactions. Click on [ERC-20 Token Txns] and you will see the tokens you just bridged.
You can see your bridged tokens here
Click on the token name at the right to find the smart contract address for each and copy it. Now open Metamask and click on [ADD TOKEN].
Metamask will auto-populate the fields after pasting the contract address
Paste the contract address in its respective field. The data will populate, click [Next] and you will see the token in the Metamask interface. Repeat this process for other tokens you might want to bridge such as the IDEX token.
