Gets the UTXOs that reference a given set of addresses.


addresses: []string,
limit: int, //optional
startIndex: { //optional
address: string,
utxo: string
sourceChain: string, //optional
encoding: string, //optional
) ->
numFetched: int,
utxos: []string,
endIndex: {
address: string,
utxo: string
encoding: string,
  • utxos is a list of UTXOs such that each UTXO references at least one address in addresses.
  • At most limit UTXOs are returned. If limit is omitted or greater than 1024, it is set to 1024.
  • This method supports pagination. endIndex denotes the last UTXO returned. To get the next set of UTXOs, use the value of endIndex as startIndex in the next call.
  • If startIndex is omitted, will fetch all UTXOs up to limit.
  • When using pagination (ie when startIndex is provided), UTXOs are not guaranteed to be unique across multiple calls. That is, a UTXO may appear in the result of the first call, and then again in the second call.
  • When using pagination, consistency is not guaranteed across multiple calls. That is, the UTXO set of the addresses may have changed between calls.
  • encoding specifies the format for the returned UTXOs. Can be either "cb58" or "hex" and defaults to "cb58".
