Startup Idea : Escrow service for Cryptocurrency

People are starting to utilise crypto to buy items and assets and the problem is sending and receiving money! Once you send funds to someone you can not retrieve it back without the receiver returning it back. No way of claiming it back. Therefore a trustful escrow service will be your middle man to receive and release funds once both parties are happy! Commission based model will benefit the company. Therefore need a secure software which is transparent for both parties to view funds in wallet before releasing.
