In order for users to use their POLK in the protocol, Polkamarkets has partnered with Meter to ensure a stable and secure bridge for the POLK token between Ethereum and Moonriver.
How to bridge your POLK from Ethereum Mainnet to Moonriver?
Step 1: Head to https://passport.meter.io/ and connect your wallet
Step 2: Choose Moonriver Mainnet as “To” Network
Step 3: Choose Ethereum in the “From” section on top, and POLK as the token, and input the amount you desire to bridge.
Step 4: Click Start Transfer.
Allow meter.io to use your $POLK. You’ll get the following metamask popup — You’ll only need to perform this step once.
Step 5: Confirm the transaction. You’ll get the following screen while the transaction awaits to confirm.
Step 6: After transaction confirmation, the tokens will make their way onto Moonriver through Meter’s bridge.
The process requires 25 block confirmations for the bridge deposit transaction on the Ethereum side, which may take 6 to 10 minutes. You can read all about it on Meter’s documentation.
Step 7: Configure Moonriver network on your metamask.
If you haven’t configured the Moonriver network in your Metamask, please do so by using Moonbeams’ documentation:
Head to https://docs.moonbeam.network/tokens/connect/metamask/ and click “Connect to Moonriver”. You’ll be prompted with the following Metamask popups:
Click Approve and Switch network.
Step 8: Add POLK as a custom token in your metamask. The token’s address in Moonriver is the following: 0x8b29344f368b5FA35595325903fE0eAab70C8E1F
Copy and paste the Moonriver POLK token smart contract address into the Token Contract Address field, as shown above. Click Next.
You’re all set and your POLK is ready to use on Moonriver 🎉
You’ll be able to bridge your POLK back to the Ethereum Mainnet using the same exact process. Just switch the “From” and “To” networks on Meter and repeat the steps above.
