dangerousfreedom - seraphis wallet work until regtest

Proposal closure/repurposed 29th March 2026

• 26.25 XMR has been repurposed to fund [Integrate FCMP++ into monero-inflation-checker ](https://repo.getmonero.org/monero-project/ccs-proposals/-/merge_requests/645)

Deadline update: July 1, 2025

Prior to the deadline, the proposer MUST provide regular updates on their progress as per the CCS rules.

If the provided updates/progress (or lack thereof) is unsatisfactory, all remaining funds can be relinquished either before or after the deadline.

The community will then seek another person/team to take over. If this cannot be accomplished within a reasonable timeframe, the funds will be repurposed or reallocated to a similar proposal (subject to community consensus).

What and Why ?

Since we have now a basic demonstrator of a wallet using a mock ledger, my next goal is to have it on a real ledger. Many components are well developed for that goal like the enote_scanner from @jberman with @SNeedlewoods modifications and the serialization functions from @jeffro256 to enable write/reading transactions into a block in a blockchain file. So the idea is to put all the components together and finish developing the remaining ones in order to have a functional (local) regtest.

The tasks I can foresee for that goal are:

• Review @ghostway's KeyContainer to get it into its final form
• Have a working MockLedger that correctly handles legacy and seraphis enotes.
• Have a prototype of a wallet that loads a legacy wallet, derive a seraphis wallet from that and create seraphis transactions (both using Grootle proofs and FCMP) using legacy enotes.
• Create the basic functions to mine blocks and send enotes to an user.
• Save/Load the blocks into the blockchain using a LMDB database.
• Make sure to have a basic wallet working on a LMDB regtest database capable of doing basic functions like loading the wallet keys and its enote/history, transferring, visualizing and making knowledge proofs on enotes.

There are many intermediary tasks that would be necessary to do that I am not fully aware of now.

Who?

• I did this, this, this and this previous works.

I propose to work for 42 USD per hour, 20h per week, for 12 weeks (or until we have a functional seraphis wallet in regtest), which makes 80.64 XMR considering 125 USD/XMR.
