Properties​

dumpMempool​

dumpMempool(): Promise<void>
Dumps the live Blockfrost mempool to console.

getAddressesWithAssetClass​

getAddressesWithAssetClass(assetClass: AssetClass): Promise<{
  address: Address
  quantity: bigint
}[]>
Returns a list of addresses containing the given asset class.

getAddressTxs​

getAddressTxs(address: Address): Promise<TxBlockInfo[]>
Returns all transactions which spend inputs from, or return UTxOs to, the given address

getTx​

getTx(id: TxId): Promise<Tx>
Note: only works for Conway era onward. If you need to get Txs from previous eras use getTxInfo() instead

getTxInfo​

getTxInfo(txId: TxId): Promise<ExtendedTxInfo>
Simplified version of getTx() that works for all eras

getUtxo​

getUtxo(id: TxOutputId): Promise<TxInput>
If the UTxO isn't found a UtxoNotFoundError is thrown If the UTxO is already spent a UtxoAlreadySpentError is thrown

getUtxos​

getUtxos(addr: Address): Promise<TxInput[]>
Gets a complete list of UTxOs at a given Address. Returns oldest UTxOs first, newest last.

getUtxosWithAssetClass​

getUtxosWithAssetClass(
  address: Address,
  assetClass: AssetClass
): Promise<TxInput[]>

hasTx​

hasTx(txId: TxId): Promise<boolean>

hasUtxo​

hasUtxo(utxoId: TxOutputId): Promise<boolean>

isMainnet​

isMainnet(): boolean

latestEpoch​

latestEpoch: Promise<any>

networkName​

networkName: NetworkName

now​

now: number
ms since 1970 Note: the emulator uses an arbitrary reference, so to be able to treat all Networks equally this must be implemented for each CardanoClient

parameters​

parameters: Promise<NetworkParams>
Note: this requires two API calls to blockfrost, because we also need information about the tip

projectId​

projectId: string

submitTx​

submitTx(tx: Tx): Promise<TxId>
Submits a transaction to the blockchain.
