Audited the wallet surface (real money: Cashu proofs, Lightning, NWC).
Most of it is solid — the Cashu singleton init with browser-CORS mint
probing/auto-heal, the send/receive token flows, the Lightning receive
path (double-tap guard + redeemed-quote listener cleanup + actionable
CORS errors), and the melt-based send all check out and match the zap
path.
One real money-loss gap: removing a mint calls
mintRepository.deleteMint(), which drops that mint's proofs from the
device — so removing a mint you still hold sats in strands those funds.
There are two remove-mint dialogs and they disagreed:
• MintPrivacyManager already warned with the concrete at-risk balance.
• CashuWallet's dialog showed only a generic static "make sure you've
withdrawn funds" line — no balance, no escalation — so a user could
delete a mint holding sats with effectively no warning.
Brought CashuWallet up to (slightly past) parity: when the mint being
removed has a non-zero balance it now shows a loud red warning with the
exact sats at risk and relabels the button "Remove anyway"; empty mints
keep the mild yellow note. Deletion is still allowed (a permanently
offline mint must be removable even with a stuck balance) — it's now an
informed choice, not a silent one.
