WeChat Pay (JSAPI/Native/H5/MicroPay) with constant-time
HMAC notify, UPI 2.0 (collect/intent/mandate/VPA),

EMVCo MPM TLV + CRC-16/CCITT-FALSE encoder for
PromptPay (TH), PayNow (SG), DuitNow (MY), QRIS (ID).

smart-byte-zk Selective-disclosure ZK primitives.
Real: Bulletproofs over Ristretto255 (range proofs at
8/16/32/64-bit), RangePredicate / InequalityPredicate /
SetMembershipPredicate all delegating to Bulletproofs.
Stubs (documented): Groth16, PLONK — deterministic
placeholder proofs satisfying ZkScheme trait for future
arkworks integration. AnonCred sketch + VerifiablePresentation
builder.
EOC (1 crate, ~3000 LOC, 36 tests)
eoc-rag RAG orchestrator. Naive (Lewis 2020), HyDE (Gao 2022),
RAG-Fusion + RRF (Cormack 2009), Self-RAG (Asai 2023)
with Retrieve/ISREL/ISSUP/ISUSE critique tokens,
Corrective RAG (Yan 2024) with retrieval evaluator
+ external fallback, Adaptive RAG (Jeong 2024)
complexity router. Chunking: sentence-window, semantic,
recursive, late-chunking. Span-backed citations with

//! # `op-ewallets-asia` — APAC e-wallet rail adapters
|
|
//!
|
|
//! Acceptance adapters for the dominant Asia-Pacific e-wallets and
|
|
//! account-to-account fast rails:
|
|
//!
|
|
//! - **Alipay** (Cross-Border Open API v3) — direct-debit, QR-code,
|
|
//! mini-program.
|
|
//! - **WeChat Pay** — JSAPI, Native (merchant-presented QR), H5,
|
|
//! MicroPay (consumer-presented QR).
|
|
//! - **UPI 2.0** (NPCI, India) — collect, intent, and recurring-mandate
|
|
//! flows + VPA resolution.
|
|
//! - **Paytm** — Standard Checkout + Paytm UPI intent.
|
|
//! - **GrabPay** (Pay-with-Grab) — SEA super-app rail.
|
|
//! - **GoPay** (Gojek) — Indonesia super-app rail.
|
|
//! - **Touch'n Go eWallet** — Malaysia.
|
|
//! - **PromptPay** (Thai BoT EMVCo MPM), **PayNow** (Singapore ABS),
|
|
//! **DuitNow** (Malaysia PayNet), **QRIS** (Indonesia BI) —
|
|
//! interoperable A2A QR rails over EMVCo MPM.
|
|
//! - **Refund + reconciliation** — symmetric semantics across all rails.
|
|
//!
|
|
//! ## Domain shape
|
|
//!
|
|
//! Every wallet boils down to a [`ChargeIntent`] in some
|
|
//! [`op_core::Currency`] for a [`op_core::Money`] amount, presented to
|
|
//! the consumer in a rail-specific way (QR, deeplink, JSAPI prepay
|
|
//! handle), then either authorized synchronously (push payment) or
|
|
//! confirmed asynchronously by a notify callback (pull payment).
|
|
//! The [`AsiaWallet`] trait normalizes that into one shape so a
|
|
//! merchant orchestrator can dispatch across rails without
|
|
//! pattern-matching at every site.
|
|
//!
|
|
//! ## Determinism + offline first
|
|
//!
|
|
//! This crate is **transport-free**. Codecs (EMVCo MPM TLV, JSON
|
|
//! request shapers) are pure functions over `&[u8]` / `&str`.
|
|
//! Signature verification is constant-time over operator-supplied
|
|
//! key material. The HTTP transport for Alipay / WeChat / Paytm is
|
|
//! injected via a `Transport` trait the operator implements (or
|
|
//! mocks in tests) — keeping the crate small, testable, and free
|
|
//! of `reqwest`/`tokio` baggage in environments (Cloudflare Workers,
|
|
//! POS firmware) that ship their own HTTP layer.
|
|
//!
|
|
//! ## Modules
|
|
//!
|
|
//! - [`wallet`] — `AsiaWallet` trait + `WalletKind` + intent/result.
|
|
//! - [`alipay`] — Alipay Cross-Border Open API v3 adapter.
|
|
//! - [`wechat`] — WeChat Pay v3 adapter.
|
|
//! - [`upi`] — UPI 2.0 (collect + intent + mandate + VPA).
|
|
//! - [`paytm`] — Paytm Standard Checkout + Paytm UPI intent.
|
|
//! - [`grab`] — GrabPay (Pay-with-Grab).
|
|
//! - [`gopay`] — GoPay (Gojek).
|
|
//! - [`promptpay`] — PromptPay (Thai EMVCo MPM).
|
|
//! - [`paynow`] — PayNow (Singapore EMVCo MPM).
|
|
//! - [`duitnow`] — DuitNow (Malaysia EMVCo MPM).
|
|
//! - [`qris`] — QRIS (Indonesia EMVCo MPM).
|
|
//! - [`tng`] — Touch'n Go eWallet (Malaysia).
|
|
//! - [`refund`] — symmetric refund + reconciliation semantics.
|
|
//! - [`error`] — sealed error enum.
