## V1 Subcourt IDs (Ethereum Mainnet)

The General Court ID is `0` on V1 (different from V2, where the General Court is ID `1`).

Check current subcourt IDs and parameters on [KlerosBoard](https://klerosboard.com/).

### Generating extraData

To specify a subcourt and juror count in V1:

```
const generateArbitratorExtraData = (subcourtID, noOfVotes) =>
  `0x${parseInt(subcourtID, 10).toString(16).padStart(64, "0")}${parseInt(noOfVotes, 10).toString(16).padStart(64, "0")}`;

// Example: General Court (0), 3 jurors
generateArbitratorExtraData(0, 3);
// "0x00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000003"
```
