User flagged: a buyer's cart can span multiple sellers, so 'per-(buyer, seller)'
isn't really 1:1. The right framing is per-Payment: Amanat already creates N
Payment records for an N-seller cart (one per sellerOfferId), and each gets
its own derived destination + RN intent + buyer-side approve+pay tx pair.
PRD now explicitly:
- Recommends per-Payment keying (which collapses to per-(buyer, sellerOfferId)
via the existing uniq_pending_request_network_by_buyer_session index)
- Documents the multi-seller cart UX (N approve+pay pairs in sequence, with
clear progress indicator, mid-cart abandonment is fine)
- Notes RN's ERC20FeeProxy is single-destination by design (no atomic split
in v1; future Amanat splitter contract is out of scope)
- Updates open questions to monotonic derivation counter, immediate sweep,
single-use addresses (no rotation), and cold-payment recovery
- Scope explicitly mentions cart-aware buyer UX as part of task #7

In-house Request Network checkout went fully end-to-end on dev today.
A real 0.01 USDC payment flowed through wallet connect -> approve ->
ERC20FeeProxy.transferFromWithReferenceAndFee -> RN webhook ->
TransactionSafetyProvider -> Payment.status=completed -> page success
state. Tx 0x494c77a29161b5100d8e0b1ac675f1822955d0bb3633ecdbfafb886f84f2f320.
Docs:
- New PRD: Wallet, Multichain, Confirmations, AML, Trezor
(5 follow-ups, each sized for an independent contributor)
- Updated PRD: Request Network In-House Checkout (phases 0..3 done,
phase 4 partial, phases 5-6 not started)
- Updated handoff: deployed versions, what is working end-to-end,
follow-up tasks index
Taskmaster: 5 new top-level tasks (#7..#11) covering ephemeral
destination wallets, multichain proxy registry + USDC/USDT, runtime
confirmation thresholds, optional seller-paid AML screening, and
Trezor signing for admin actions. Tasks are scoped fine-grained so
each is independent enough for kimi to pick up.
