- usePayPaymentPointer now checks the seller's committed payment_hash (from
the accepted offer) against the invoice actually paid; a swapped pointer
is rejected before any payment.
- PayWithSats no longer offers an in-app sats Pay button for a non-SATS
offer: a fiat amount is never paid as if it were sats. New
marketUi.pay.nonSats (en/es).
- ListingOffersPanel passes paymentHash + currency through.
Docs updated (still open: NWC->WebLN/Cashu fallback, empty preimage).
The escrow mint was silently the buyer's preferred/first trusted mint
(useCashuEscrow: prefs.preferredMintUrl || mints[0].url) with no UI, even
though the seller redeems there. Now:
- the escrow dialog shows the mint and lets the buyer pick from their
trusted mints (defaults to their preference);
- a mint whose NUT-06 info advertises no NUT-11 (P2PK) support is blocked
with a clear message before minting (cashuEscrow.mintSupportsP2PK);
- the create call uses the selected mint.
Still open (scoped separately): consult a seller-advertised mint and
seller-side receive from an unfamiliar mint. Recorded in the audit.
Next batch from MARKETPLACE_FLOW_AUDIT.md:
- bolt11.ts: getBolt11Expiry / isBolt11Expired; usePayPaymentPointer refuses
an expired invoice before paying (a lapsed offer invoice used to fail deep
in the wallet with a confusing error).
- PayWithSats shows unsupported pointer kinds (creq/clink) as unavailable up
front instead of enabling a button that fails after the click.
- useTradeAttestations: verify events (onlyVerified) and keep the newest per
(author, kind, d), so a newer s=revoked supersedes a stale valid copy;
useTradeReputation no longer trusts unverified relay events.
- EscrowRequestDialog persists the minted token locally before publishing
(lib/pendingEscrow.ts), so a failed send cannot strand the locked funds.
Deep audit (MARKETPLACE_FLOW_AUDIT.md): full trade/escrow/offers lifecycle,
severity-ranked findings, and a state-coverage matrix.
Fixes:
- Grid Mark as sold now opens MarkSoldDialog, so the kind-31871 attestation
(buyer, method) is recorded from the grid too, not just the detail page.
- Offers accept attaches a payment pointer only when the accepting user is the
listing owner (seller); previously the buyer could publish their own lud16 as
the payee and misdirect payment.
- advertiseEscrowKey refuses to publish kind 0 before the profile loads, so it
cannot overwrite name/picture/lud16 with a cashu_escrow-only profile.
- useListingOffers passes requireAny, so the offers panel error state actually
fires on an outage (previously an outage looked like no offers).
- Offer messages invalidate the offer queries, so accept/counter/decline update
immediately instead of after the stale window.
