This repository contains info and discussions about a so-far hypothetical full core wallet rewrite from scratch to implement Seraphis and Jamtis support in the Monero codebase, a project with a "working title" of wallet3.
The code would use @UkoeHB's Seraphis function library that is here. (See also the resources page in the strategy wiki.) Whether and how it would also internally use the existing wallet2 is unclear so far.
There is a principal wallet migration strategy described in the strategy wiki here that is also called wallet3. What is described here differs from that because the starting point is quite different: The seraphis_wallet code from UkoeHB that the strategy is built on did not come to be as originally expected, but an extensive Seraphis function library that should contain all the building blocks needed for building a wallet proper.
The issues in this repository describe important issues that would play a role in such a full wallet rewrite, which as already mentioned may or may not happen.
