Polkamarkets V2 markets are usually resolved through the crowd-sourced POLK Bond Escalation process.

If you believe a market is being resolved under the wrong outcome and want it to be reviewed by a jury, you can apply for Arbitration with Kleros.

Step 1: Head to the closed Market and click “Apply for Arbitration”

Step 2: Switch network to Ethereum

Even though Polkamarkets’ protocol is deployed on Polygon, arbitration on a Kleros court happens on the Ethereum Network. The process will start in the Ethereum Network and will be sent afterwards to Polygon through a proxy. You can read about its entire flow in the following article

In the screenshot below, you’ll be requested to switch to the Ethereum Network, in order to start the process

Step 3: Review Information and Apply for Arbitration

After switching your wallet to the Ethereum Network, you’ll be required to review all the arbitration information, and start the arbitration process. That will achieved by clicking the “Apply for Arbitration” button and confirming the transaction

IMPORTANT: Arbitration by an external court with several jurors on the blockchain carries operational costs + bounties. Therefore, this process will have a cost of 0.496 ETH

Step 4: Wait for the arbitration process to be started

After applying for arbitration, the process information must be proxied and validated by the Polygon Network and then sent back to the Ethereum Network. That happens in the background. This process usually takes 1-2 days. While it is underway, you’ll see the following screen.
