Is An XMR Version of Nunchuk Wallet Technically Possible?
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.
@xmr_unlimited That’s probably true, but fund security/access isn’t my main problem. I don’t like having to go through RINO to begin with. I’m not very familiar with multisig, but I believe they at least have a Private View Key, and partial access to the Private Spend Key. Their own FAQ admits they can see outgoing transaction info (this can be mitigated by the receiver always using clean subaddresses of course, but RINO still has the info regardless).
The use of email and accounts also means RINO stands to have access to metadata about user activity, especially if they use convenience features like fast sync & cross-device access. I’d prefer a multisig solution without the middleman if possible.
