  1. addresses - []string - A list of addresses.
  2. limit - Int - (optional) The limit of UTXOs to return. If limit is omitted or greater than 1024, it is set to 1024.
  3. startIndex - Object - (optional) If startIndex is omitted, will fetch all UTXOs up to limit. When using pagination (i.e 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.
  4. address - String

    utxo - String

  5. sourceChain - String - The ID or alias of the chain the asset is being imported from.
  6. encoding - String - (optional) Encoding sets the format for the returned UTXOs. Can be either "cb58" or "hex". Defaults to "cb58".


  1. numFetched - Int - (optional) Number of UTXOs fetched.
  2. utxos - []string - a list of UTXOs such that each UTXO references at least one address in addresses.
  3. endIndex - Object - Denotes the last UTXO returned. To get the next set of UTXOs, use the value of endIndex as startIndex in the next call.
  4. address - String

    utxo - String
