[CCS Proposals] selsta opened merge request #697: selsta full-time monero development (3 months) (22) repo.getmonero.org/monero-project/ccs-proposals/-/merge_requests/697

<jpk68:matrix.org> > <tobtoht> I don't think we should allow third party hardware integrations in the main repo. We can set up a generic USB interface, and if a vendor wants to offer Monero support they can go ahead and implement that. We have given Trezor/Ledger way too much leverage over our code and dependencies.

<jpk68:matrix.org> Does anyone have any thoughts on whether this should be for the 'hot' or 'cold' path? I think the latter would make much more sense

<jpk68:matrix.org> A theoretical generic USB interface, that is

<ofrnxmr:xmr.mx> Both? Wdym

<jpk68:matrix.org> I'm talking about device.hpp vs. device_cold.hpp

<jpk68:matrix.org> Currently, Ledger uses the 'hot' one and Trezor uses the 'cold' one

<jpk68:matrix.org> Ledger's approach is a lot more interactive and seems somewhat fragile

<jpk68:matrix.org> Like, you're forcing vendors to implement arbitrary elliptic curve steps instead of support for signing different blobs

<jpk68:matrix.org> Then there's also the question of the wire format (Protobuf? CBOR?), and what transports should be used. Trezor's current model seems pretty reasonable.
