Seeking Feedback: Would a Fedimint-Based Escrow Module Be Useful for bitpay

[Harshdev098]

Hey I'm working on a potential Fedimint escrow module and trying to validate whether it could solve a real problem before investing more development effort.

the current design is as a buyer to lock ecash into an escrow contract specifying a buyer, seller, arbiter(s). In the normal case, the buyer releases funds to the seller. On a dispute or after a timeout, the arbiter signatures will be valid to sign the outcome to Release the funds to the seller(if seller wins) or refund to the buyer(if buyer wins) the decisions made will be offchain. The federation enforces contract rules and signature verification.
I'm particularly interested in understanding whether people would actually use something like this.
and have a few questions regarding it
Does anyone currently use any form of escrow for Bitcoin or ecash transactions? Are there requirements or concerns that would prevent you from using such a system? or if it could be useful for bitpay in future perspective
I'd appreciate any feedbacks on this!
