Here is a recent Nebulas DApp which, in my opinion, has real life usability for us, cryptoheads:
www.nas-escrow.comThe smart contract can be found on the website and It allows to trade any asset by holding the agreed amount of NAS on the contract until the funds are being released by the buyer. It works like any other escrow service without the transaction fee and without any 3rd party centralized storage involved.
In case of a dispute, the developer will handle it without any fee. In the future, the contract would allow new address enrollment for the dispute handling in exchange for a small fee. A rating system will be also put in place.
Currently the dashboard allows the sellers/buyers to initiate an escrow transaction, by providing asset agreement, NAS price, and other relevant info. The shipping cost will be calculated based on selection.
Messages can be exchanged between parties and an action history is recorded on the blockchain. The dispute will be handled only based on that information.
Please feel free to try it. Any feedback is much appreciated as well as feature requests. Hope no dispute will be needed and you will be able to trade assets as we all want: in a safe and simple manner.
