Mainnet Arbitrator address: 0x988b3A538b618C7A603e1c11Ab82Cd16dbE28069

Blockchain subcourt: 1

Script to generate the arbitrator extra data:

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

It also says extra data includes

(If appeals are allowed) Stake multipliers representing multipliers of the appeal cost that a party must pay for a new round (in basis points)

however, KlerosLiquid derives the appeal cost from the number of jurors.

Reads for frontend

Mostly static data:

• extraData: ClaimsManagerWithKlerosArbitration.klerosArbitratorExtraData()
• subCourt and noOfVotes: Parse extraData
• KlerosLiquid.getSubCourt(subCourt).timesPerPeriod (https://github.com/kleros/kleros/blob/master/contracts/kleros/KlerosLiquid.sol#L37)
• KlerosLiquid.arbitrationCost(extraData)

Dispute-specific data

• KlerosLiquid.disputeStatus(disputeId) (https://github.com/kleros/kleros-interaction/blob/master/contracts/standard/arbitration/Arbitrator.sol#L23)
• KlerosLiquid.currentRuling(disputeId)
• KlerosLiquid.disputes(disputeId).period, KlerosLiquid.disputes(disputeId).lastPeriodChange, KlerosLiquid.disputes(disputeId).ruled
• KlerosLiquid.appealCost(disputeId, extraData)
• Future appeal costs can be calculated using KlerosLiquid.courts(subCourt).feeForJuror and https://github.com/kleros/kleros/blob/master/contracts/kleros/KlerosLiquid.sol#L797
