Instance Method Details

#asset_unspent_outputs(asset_id: nil, amount: nil) ⇒ Object

Returns an Enumerable object yielding unspent asset outputs for the given asset ID and amount. Each unspent output is a BTC::AssetTransactionOutput instance with non-nil transaction_hash, index, asset_id, value attributes. Additional information about outputs and fees may be used to optimize the set of unspents.
