Constructors

Emulator(accounts: { address: Address; assets: Assets; }[], protocolParameters?: ProtocolParameters)

Properties

blockHeight: number

chain: Record<RewardAddress, { registeredStake: boolean; delegation: Delegation; }>

Only stake key registrations/delegations and rewards are tracked. Other certificates are not tracked.

datumTable: Record<DatumHash, Datum>

ledger: Record<FlatOutRef, { utxo: UTxO; spent: boolean; }>

mempool: Record<FlatOutRef, { utxo: UTxO; spent: boolean; }>

protocolParameters: ProtocolParameters

slot: number

time: UnixTime

Methods

awaitBlock(height?)

awaitSlot(length?)

awaitTx(txHash: string): Promise<boolean>

distributeRewards(rewards: Lovelace)

Emulates the behaviour of the reward distribution at epoch boundaries. Stake keys need to be registered and delegated like on a real chain in order to receive rewards.

getDatum(datumHash: DatumHash): Promise<Datum>

getDelegation(rewardAddress: RewardAddress): Promise<Delegation>

getProtocolParameters(): Promise<ProtocolParameters>

getUtxoByUnit(unit: string): Promise<UTxO>

getUtxos(addressOrCredential: Address | Credential): Promise<UTxO[]>

getUtxosByOutRef(outRefs: OutRef[]): Promise<UTxO[]>

getUtxosWithUnit(addressOrCredential: Address | Credential, unit: Unit): Promise<UTxO[]>

log()

now(): UnixTime

submitTx(tx: Transaction): Promise<TxHash>
