This is something we have been working on as well. Specs looks promising... Here is what extra things we are looking for, wonder if you guys consider implementing?!

• Utilizing Hive escrow operations for HIVE/HBD tokens is must
• Utilizing multi-chain tokens directly via multisig. Hive accounts can hold other crypto directly now with our new approach on Ecency signup. So ability to use those would be great use case and show casing true spirit of web3. CHAIN:TICKER does help, I guess multisig could be somehow built separately by UI/platform or as separate package.
• For disputes, internal group chat is necessary so each trade can have buyer, seller and platform/arbitrator. For chats, sub-comments could be utilized with encryption but when disputes happen, it should be 3 way encryption. So only 3 accounts could read messages.
