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.

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. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Description
Replace the single shared Amanat destination wallet with a per-(buyerId, sellerOfferId) HD-derived address sent to Request Network on intent creation, plus sweep-on-approval and an admin UI.
Details
See PRD - Wallet, Multichain, Confirmations, AML, Trezor.md §1. Files: new backend/src/services/payment/wallets/derivedDestinations.ts (getDestinationFor(buyerId, sellerOfferId) → {address, derivationPath, chainId}); Payment schema add metadata.derivedDestination; requestNetworkPayInService.ts override destinationId before POST /v2/secure-payments (we confirmed RN accepts different destinations per intent); new sweep cron + admin manual-trigger endpoint gated on Transaction Safety Provider; admin UI at /dashboard/admin/derived-destinations with address, balance, last sweep tx (BscScan link), ownership status. Open questions to settle first: HD vs disposable EOAs vs smart-forwarder (recommended HD); sweep cadence (recommended immediate); granularity (recommended per-(buyer, seller), not per-payment); re-use vs rotate after sweep. KMS-rooted seed; backend never holds raw private keys; signing via KMS API (Task #11 Trezor flow is the longer-term replacement). Acceptance: two payments from one buyer to two sellers land on two different addresses; RN webhook fires for both; sweep is idempotent; master seed never leaves KMS.
