func (*Network) LookupTransferMetadataKey 

func (n *Network) LookupTransferMetadataKey(namespace, startingTxID, key string, timeout time.Duration, stopOnLastTx bool, opts ...token.ServiceOption) ([]byte, error)

LookupTransferMetadataKey searches for a transfer metadata key containing the passed sub-key starting from the passed transaction id in the given namespace. The operation gets canceled if the passed timeout gets reached or, if stopOnLastTx is true, when the last transaction in the vault is reached.
