Some bitcoin escrow software has achieved a degree of popularity, including purse.io, hodlhodl, and bisq. One thing those services don't have -- and lightningescrow does have, already (in closed beta) -- is a robust api that gives developers lots of control to create arbitrary escrow contracts for any purposes they want. So hopefully by being super dev-friendly we can be a service that developers build additional tools on top of, and if any of those get network effects, that boosts our popularity as well.

That's great! I'll be waiting
Hope you can do it! There were sites that worked on-chain, but they did not find popularity. How are you going to overcome this barrier?

We are working on lightningescrow.io, and we are launching later this year. 

Let me know if you have any questions

LightningEscrow.io is shaping up to be a really cool service

It’s an escrow service. It uses a combination of hodl invoices and something else.

What is your use case?

e.g., Buying something online but don't want to send seller funds up-front?  

The best that I know is the Lightning Network P2P trading bot on Telegram.
It uses Hold invoices for the escrow. Search it by the handle @LNp2pBot in Telegram as well as in Twitter.
