A chain query client responsible for all read actions from the blockchain (no write)

Required Methods

fn get_network(&self) -> Network

Query the network id (not identical to network magic)

fn query_system_start( &self ) -> impl Future<Output = Result<DateTime<Utc>, ChainQueryError>>

fn query_era_summaries( &self ) -> impl Future<Output = Result<Vec<EraSummary>, ChainQueryError>>

fn query_protocol_params( &self ) -> impl Future<Output = Result<ProtocolParameters, ChainQueryError>>

Query protocol parameters

fn query_tip(&self) -> impl Future<Output = Result<ChainTip, ChainQueryError>>

fn query_utxos_by_addr( &self, address: &Address ) -> impl Future<Output = Result<BTreeMap<TransactionInput, FullTransactionOutput>, ChainQueryError>>

Query UTxOs at an address

fn query_utxos_by_ref( &self, references: Vec<&TransactionInput> ) -> impl Future<Output = Result<BTreeMap<TransactionInput, FullTransactionOutput>, ChainQueryError>>
