Digital Currency Laboratories is building early smart contract functionality with dash. The first experiment will be a smart contract expansion oracle that seeks out onchain cross market price differences then automatically and autonomously closes the arbitrage gap then returns the proceeds minus fees to the DASH expansion oracle user.  This will be a 'safe' smart contract  experiment, initially only working for small volumes of Dash. The smart contract can be replicated manually by arbitraging price differentials on the waves network. The smart contract will send orders to operate when there is a net expansion of DASH inclusive of fees for the end user.
