Calls validatorClient.getOpenAndIssuingMiningRounds(), filters open_mining_rounds where opensAt ≤ now, selects the chronologically last opened round (array order assumption), converts payload into DisclosedContract (domain_id mapped to synchronizerId per SDK legacy behaviour), maps issuing_mining_rounds into { round, contractId } tuples.
Throws OperationError MINING_ROUND_NOT_FOUND when filters exclude everything.
Setup
import { Canton, getCurrentMiningRoundContext } from '@fairmint/canton-node-sdk';
const canton = new Canton({
network: 'NETWORK_NAME',
partyId: 'PARTY_ID',
});Minimal example
const ctx = await getCurrentMiningRoundContext(canton.validator);
console.log(ctx.openMiningRound, ctx.issuingMiningRounds.length);Parameters
validatorClient— Any object exposinggetOpenAndIssuingMiningRounds(MiningRoundClient).
Returns
Promise<MiningRoundContext> — openMiningRound contract ID string, openMiningRoundContract (DisclosedContract), issuingMiningRounds enumeration.
Errors
Throws OperationError MINING_ROUND_NOT_FOUND when no qualifying rounds exist.
Auth and party
Requires validator credentials exposing mining-round introspection APIs.
