I've read about secret sharing as a means of doing multisig in Monero, and I know services like Haveno & RINO implement 2-of-3 wallets as a service (for exchange escrow and shared custody respectively). I'm interested in a different sort of implementation, one that doesn't rely on a third party host.

Nunchuk.io, for example, develops a BTC wallet that allows multiple users to collaboratively create multisig wallets & share custody of bitcoin. They can sign/approve transactions via an integrated messenger (which is third party hosted, but doesn't technically need to be afaik). This has multiple use cases, but it interests me primarily as a trustless escrow service between individuals.

As a non-programmer, I'm curious if anything about XMR secret sharing prevents the development of an equivalent application for Monero. Haveno and RINO have their own use cases, but I'd be more interested in something that can work between individual users without any third party company/service/platform.

@japananon @monero I could build one, sounds like an interesting project.

There was an old system based on BitMessage, but it is unusable and unmaintainted: https://www.getmonero.org/resources/user-guides/multisig-messaging-system.html.

Someone is trying to build I2P-based version with an integrated marketplace: https://github.com/creating2morrow/neveko. It doesn't look very usable either, and developer is trying to do everything at once, which is usually a bad idea.

I would make it as a standalone tool that can work on clearnet and can connect to other software

@silverpill @monero The existence of a tool like this would be extremely welcome. In my opinion, at least, but I'm sure a lot of other people would find it valuable once they discover it.

@japananon @monero I talked with some devs and learned about plans to add GUI for mutlisig to Feather wallet. But it is not clear when this will happen because Monero multisig still has experimental status (its security is not proven).

I could try to build an alternative wallet app, but there's a risk that Feather will add it first and my effort would be wasted.

Also, this just popped up in my feed: https://monero.im/post/3925
