What

Work full-time 4 months on:

• Completing the FCMP++ integration.
  • We will be launching an alpha stressnet soon.
    • I will help triage and fix identified bugs/issues.
    • The plan to mainnet: alpha stressnet, beta stressnet, finish code review/audits, testnet, mainnet.
  • Work on the following, some of which @jeffro256 and @articmine are already working on:
    • Review and implement updated fee logic for FMCP++ (@articmine is currently finalizing a proposal).
    • Review @jeffro256's cold wallet <> hot wallet integration.
    • Review @jeffro256's HW wallet work.
    • Multisig.
      • Manage the tree correctly.
      • Use the monero-fcmp-plus-plus crate for core logic.
    • Final touchup tasks.
      • Final pass-through cleaning up the FFI (removing asserts/unwraps, returning errors correctly, clippy/fmt).
      • Final organizational changes in line with thoughts mentioned here.
      • See this TODO list tracker.
• Review the Carrot integration.
• Update documentation for the FCMP++ integration, using the same format as in this (now outdated) WIP PR.
• Start submitting piecemeal FCMP++ PR's to the main Monero repo.
• Review @vtnerd's p2p encryption PR: https://github.com/monero-project/monero/pull/8996
• Continue Seraphis wallet library work:
  • My next task on this front is to bring the Serpahis lib async scanner into the current wallet API (source)
  • In the latest round of tests, I observed scanning speed-ups of 50-60% with a clearnet remote node, 35-45% with a tor node, 25-35% with a local node.
  • The async scanner has already undergone a round of review (source)
  • To be usable in the wallet API, the following still needs to be implemented:
    • A mutable subaddress lookahead (source)
    • Pool scanning (source)
    • A clean way to save tx metadata (source)
    • Integrate the FCMP++ tree builder + Carrot scanning.
• Misc. high priority tasks as they arise, including vulnerability response as requested.

A note: once I've completed all work on FCMP++/reviewing Carrot (and after reviewing p2p encryption), I may work on Serai independent from this CCS. I would like to see Serai launched and operating smoothly (and technically I still owe @kayabaNerve more work on Serai in exchange for their research into FCMP's). I would then return to continue Seraphis wallet library work.
