Constructors

new
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.
