The problem is that all the effort is still on the developer to actually build a user interface, while Gridlock already has it built. Additionally, any company can build on the Gridlock storage network using the SDK. It's secure MPC without the work of bringing that to the user and explaining it. In a clear way.
Upon checking your profile, I noticed that you’re related to Gridlock. Adding a disclaimer to your original comment would’ve been more appropriate in my opinion.
Also, having your product open-sourced and/or audited increases trustworthiness. You mentioned going open-source and being audited in 2021 but neither happened as far as I can find. That’s fine, just different than OP’s project.
On the flip side, I noticed this Q&A from your docs that I think is at least re-assuring:
“What happens to my assets if Gridlock shuts down?
Should Gridlock ever become unavailable, you are still safe and protected! The built-in Eject Feature allows you to access your crypto independently without Gridlock. This is the definition of self-custody where you are in full control!”
PS. I’m not the target audience for these type of products. I stay away from most crypto stuff. I just stumbled upon this thread and wanted to share my thoughts :)
