I like something like this, but wish it's some sort of decentralized escrow based on advanced smart-contract system.
If it's centralized, you will probably have go through alot of legal processes to keep things safe and secure for you and your customers...
Is the escrow non-custodial? And can you handle being an arbiter in times of disagreements between peers?
I am working on developing an easy to use 2-3 multi-sig with the platform, hoping to make the platform simple and easy to use.
I would love to develop a decentralized escrow service, but i heard that it cannot be done with smart contracts, and i do not really get the idea of using smart contract in an escrow platform (I do apologize for my lack of knowledge).
If that is the case then you should abandon this project by locking the thread, what you are trying to accomplish is not within your reach, but maybe a developer who had ample knowledge can materialize this idea, but until then lock this thread since you already posted that you cannot do it.
