Worldpay 2026 Global Payments Report (Worldpay)

Worldpay published the 2026 edition of its Global Payments Report in which it argues that global consumer payments are rapidly shifting toward digital wallets and app‑based rails, with cards adapting and crypto evolving rather than disrupting. The report documents rising wallet dominance in e‑commerce and at point of sale, regional variation in account‑to‑account systems, and the continued but declining direct share of cards as usage migrates into wallets. These developments sharpen questions about governance of national fast‑payment infrastructures, merchant routing and fee regulation, cross‑border interoperability, and the competitive position of bank‑issued cards versus platform wallets and “superapps.” They also highlight how buy-now-pay-later and card‑backed installments blur prudential and consumer‑protection boundaries, and how stablecoin‑based payment rails may need bespoke oversight alongside traditional systems.

An Efficient Frontier Analysis of Stablecoin Reserve Management (VISA)

VISA published an article in which Ezechiel Copic uses an efficient frontier framework to show how new U.S. and EU stablecoin rules compress reserve returns and reorient issuer economics toward liquidity and resilience. The article models pre‑regulation reserve strategies using Tether’s historical mix to illustrate a wide opportunity set, then re‑estimates frontiers under the U.S. GENIUS Act and the EU’s Markets in Crypto‑Assets Regulation. Under GENIUS, a narrow set of high‑quality liquid assets leaves only a thin band of feasible risk‑return combinations, making reserve management resemble liquidity engineering rather than portfolio optimization. Under MiCA, lower euro‑area rates and binding bank‑deposit floors further depress and compress the frontier, especially for “significant” issuers. The analysis implies competition will shift from balance‑sheet yield to technology, distribution, and compliance, while leaving open how far reduced issuer economics may constrain market entry and long‑run innovation. [VISA]

Tokenized Finance (IMF)

The IMF’s Tobias Adrian argues that tokenization is a structural reconfiguration of financial architecture that shifts trust and risk management from institutions to programmable infrastructures. Tokenization enables atomic, real-time settlement and embedded compliance across money, banking, capital markets, and financial market infrastructures, compressing value chains but also accelerating liquidity dynamics and potential stress transmission. For emerging and developing economies, although tokenization may lower payment and market-access frictions, it heightens risks of volatile capital flows, currency substitution, and fragmented liquidity. The note emphasizes that the long-term success of tokenization depends on anchoring digital finance in public trust through clear policy frameworks and safe settlement assets, robust governance of code, legal certainty, and international coordination. Absent such anchors, tokenization risks amplifying financial instability through speed, concentration, and fragmentation, as contract-based risk management alter the nature of settlement, liquidity, and systemic risk. [IMF]

Results of the SNB 2025 Payment Methods Survey of Private Individuals (SNB)

The Swiss National Bank (SNB) reported its 2025 survey results on payment behavior among private individuals in Switzerland. The SNB finds that use of payment methods at physical points of sale is largely unchanged from 2024, with debit cards leading, followed by cash and mobile payment apps, based on diary and questionnaire responses from roughly 2,000 residents. For policy and cash-infrastructure design, satisfaction with cash access has dropped from 88% to 81%, likely reflecting the continued reduction of automated teller machines and similar access points, which may pressure authorities to reconsider minimum cash-access standards or incentives for basic cash services. At the same time, only 2% of respondents support abolishing cash, underscoring that cash still fulfills a demanded role in retail payments and resilience planning. [SNB]

And now for more backfilling, more of which is to come…

Do We Really Need the Digital Euro: A Solution to What Problem Exactly? (IEA)

[April 30, 2025] The Instituto Espanol de Analysts (IEA) published a book that included a chapter by European Parliament rapporteur Fernando Navarette, that argues that a digital euro is a mis-specified response to Europe’s payments challenges and should be downgraded to a contingency “Plan B.” He contends that the core problems—trust in money post‑crisis, overreliance on non‑EU payment schemes, and stablecoin‑driven currency substitution—are better addressed through institutional and regulatory reforms, wholesale central bank digital currency (CBDC), and pan‑European instant‑payment solutions based on commercial bank money. Navarrete stresses that retail CBDC is inherently destabilizing for bank funding, raises unresolved privacy and governance risks, and risks crowding out private innovation, especially if coupled with legal tender and complex “waterfall” mechanics. He instead proposes a three‑pillar architecture: private‑led interoperable instant payments, a narrowly scoped offline digital euro, and wholesale CBDC—leaving a full retail CBDC only as a last‑resort backup if private efforts fail. [IEA]

The eNaira Journey So Far (in 2023) (CBN)

[In 2023] the Central Bank of Nigeria (CBN) published a book on the economics of digital currencies in which there was a review of how the eNaira central bank digital currency (CBDC) was designed, launched, and managed. It argues that weak demand reflects structural and institutional frictions rather than purely technological failure. The review documents a phased rollout focused on financial inclusion, payment efficiency, and monetary control, but shows that limited interoperability, burdensome onboarding, and unclear value propositions constrained uptake. It emphasizes how institutional choices around wallet tiers, distribution architecture, and bank–fintech roles reshaped market incentives, often reinforcing banks’ dominance rather than fostering broader innovation. It highlights the need to recalibrate design toward open interfaces, clearer legal and regulatory frameworks, and better alignment between central bank objectives and private‑sector business models. [CBN]

FYI I produce a monthly digest of digital fiat currency (DFC) developments exclusively for the official sector (e.g., central banks, ministries of finance and international financial institution (e.g., the BIS, IMF, OECD, World Bank)) plus academics and firms that are active in the DFC space (commercial banks, technology providers, consultants, etc.). (DFCs include central bank digital currency (CBDC), stablecoins and tokenized deposits.)

A Bright Future for Retail Central Bank Digital Currency (CBDC)? (Part 1)

April 3, 2026April 4, 2026 ~ kiffmeister ~ Leave a comment

There are a number of central bank digital currency (CBDC) trackers that provide accurate snapshots of the CBDC state of play at any point in time, like those of the Atlantic Council and Human Rights Foundation (HRF). However, as far as I know, only CBDCTracker.org also maintains a historical database of CBDC developments that it makes available to researchers. Although I’m part of the CBDCTracker.org team, I haven’t actually done anything interesting with the database until now. So here it goes.

I have long been using Figure 1 to illustrate the growth in central banks starting to explore retail CBDC.[1] The number has grown from five in 2015 to the current 117. The other trackers publish higher counts (over 130) but that’s because they count the individual countries in currency unions separately. So, for example, I count the Euro Area as one, but the Atlantic Council counts nine of the Euro Area countries separately, and the HRF counts all of them (actually 20 because they’re not yet tracking Bulgaria). My rationale for not counting the individual countries is that only the currency union’s central bank (e.g., the ECB in the case of the Euro Area) can issue the CBDC (e.g., digital euro).[2]

However, Figure 1 is based on a cumulative count that doesn’t account for central banks canceling or fizzling out their CBDC projects. In many cases the central bank makes a public announcement that it is ceasing or putting on hold its retail CBDC project (e.g., Australia, Brazil, Canada, Norway, Sweden and United States). More recently, some central banks have been pivoting out of retail CBDC into wholesale CBDC-backed tokenized deposits (e.g., China and South Korea). And then there are the quiet quitters, many of whom never got out of the research or proof-of-concept phases.

Anyways, the CBDCTracker.org database provides all of the information required to identify the central banks that have publicly shut down their retail CBDC projects, and those who have let their projects fizzle out quietly. The result of that is Figure 2, which classifies projects that are “live” as the ones that are currently launched or being actively piloted, plus, of the rest, the ones who have provided public evidence that their projects are still live within the last 12 months of the period in question. At March-end 2026, there were 34 live efforts – four that have launched, four active pilots, nine in active proof-of-concept phases, and 17 research projects for which public updates had been made since March 2025.

This seems to fly in the face of headlines, like those claiming that a clear majority of central banks see CBDC adoption in 5-10 years (Central Banking, 2026). I have a suspicion that such headline claims include the currency union double counting I mentioned above, plus wholesale CBDC (or “tokenized central bank money”) projects, which do seem to have a promising future. I suspect that if I were to recreate Figure 2 for wholesale CBDC, the numbers wouldn’t be as high, but the “live” numbers wouldn’t be far below the totals.

Meanwhile, in follow-up posts I’ll go through the reasons I think that retail CBDC projects seem to be fizzling out and give my suggestions for a possibly brighter future.

[1] Retail CBDC is a broadly available general purpose digital payment instrument, denominated in the jurisdiction’s unit of account, that’s a direct liability of the monetary authority. Wholesale CBDC is limited to a set of predefined user groups, like financial institutions, based on distributed ledger technology.

[2] I’m not saying that the Atlantic Council or HRF are necessarily wrong, because they may have their reasons for focusing on individual countries, like geopolitical and human rights angles, which may be country specific.

The Eurosystem’s Comprehensive Payments Strategy (ECB)

The European Central Bank (ECB) set out the Eurosystem’s comprehensive two pronged payments strategy, defining its vision for the evolution of European payments under rapid technological change. The first prong is upgrading core infrastructures such as T2, the real time gross settlement backbone for high value and time critical payments during business days, and TIPS, the 24/7 Single Euro Payments Area (SEPA) instant retail settlement layer, while developing distributed ledger technology based wholesale settlement via Pontes and Appia. The second prong is a retail digital euro, with tokenized deposits and regulated, EU governed stablecoins in a complementary role. The strategy links tokenization choices to preserving the singleness of money, monetary sovereignty, and financial stability, reduces dependence on non European schemes, and embeds strategic autonomy and cyber resilience into core infrastructures and retail acceptance layers. It also promotes deeper integration of cross border and corporate payments through instant payments, standardization, and interlinking fast payment systems. [ECB]

Tokenised Deposits, WCBDC and the Central Bank’s Liquidity Management (Norges Bank)

Norges Bank published a paper that analyzes how tokenized bank deposits and wholesale central bank digital currency (WCBDC) interact with central bank liquidity management under different reserve regimes and settlement designs. They model four configurations combining scarce versus ample reserves with settlement either in traditional reserves via the real-time gross settlement (RTGS) system or in WCBDC on a ledger, showing that liquidity frictions arise mainly when reserves are scarce and tokenized payments can alter banks’ reserve or WCBDC positions close to RTGS cut-off (see table below). This matters because late-in-the-day tokenized flows can force abrupt recourse to standing facilities, complicate overnight redistribution, and impair short-term rate control and monetary policy implementation, particularly in corridor or quota systems. Policy responses include deferred settlement for tokenized deposits settled in reserves and time windows or design tweaks for WCBDC activity. [Norges Bank]

Are Stablecoins and Bank Deposits Substitutes? (SSRN)

Rashad Ahmed (Anderson Institute for Finance and Economics) and Iñaki Aldasoro (BIS) posted a paper that analyzes U.S. weekly data from 2019–2025 to test whether deposit rates and reserve‑backed stablecoin holdings are substitutes. They find that higher demand deposit rates significantly slow stablecoin market capitalization growth, exploiting a nonlinear deposit‑rate pass‑through “kink” above a 3% federal funds rate, yielding effects about three times larger. This suggests bank funding conditions and monetary policy transmission now extend into stablecoin markets, with stronger substitution for USDC than USDT, aligning with USDC’s tighter links to U.S. users, and no comparable effect for bitcoin. The findings suggest that deposit‑rate regulation, the design of stablecoin regimes, and the stance of monetary policy can reallocate liquidity between banks and USD stablecoins, although identification relies on a single high‑rate episode and aggregate data that leave user‑level motives and heterogeneity across institutions unresolved.

Sorry for the long radio silence, but I was traveling this week (Switzerland for private meetings and Frankfurt to speak at Frankfurt School’s Crypto Assets Conference and the Digital Euro Association’s Annual Conference (both excellent annual conferences that you should mark your next year’s calendar for). On top of that I picked up a stomach bug (probably food poisoning along the way). Anyways I’m back in the saddle now and trying to catch up and make sure I get the monthly out on time (see below).

Bank of Uganda Looking for Consultants for CBDC Feasibility Study (BOU)

The Bank of Uganda (BOU) is inviting qualified consultants or consulting firms to submit expressions of interest to conduct a comprehensive feasibility study on issuing a central bank digital currency (CBDC) in Uganda, covering technical infrastructure, legal and regulatory aspects, economic and social impacts, operational viability, and a detailed cost-benefit analysis using both quantitative and qualitative methods. The selected firm will assess national digital and payments infrastructure, propose and apply a robust methodology, and deliver specified reports demonstrating understanding, relevant experience, and a workplan. Participation is open under Bank of Uganda procurement rules, with detailed eligibility, experience, and team composition criteria (multi-disciplinary CBDC, payments, economic, legal, cybersecurity, and change-management experts) and a minimum technical score of 70 points for shortlisting. The deadline for submissions is on April 16, 2026. [BOU]

Norges Bank’s Exploration of Central Bank Digital Currency (Norges Bank)

Norges Bank published four reports from its CBDC exploratory work, which last year concluded that introducing a CBDC is currently not warranted. The need for such a currency may, however, change in the future. The four reports published today describe the exploration work and the assessments underpinning the conclusion. Norges Bank will continue to explore tokenization and different forms of CBDC in order to introduce a CBDC should it be necessary The Bank will explore the possibilities and consequences of tokenization through activities such as experimental technology testing, also in collaboration with other payment system participants. One of the papers documents sandbox tests of a two-tier, blockchain-based retail CBDC that central bank exclusively mints and redeems, while banks and other payment service providers manage all customer relationships and data. Tests show that role-based smart contracts can technically enforce this division of responsibilities and give the central bank only aggregate, real-time circulation data, but they also highlight structural privacy risks from linkable pseudonymous addresses and operational rigidity from immutable smart contracts.

Tether Appoints KPMG to Complete First Full Audit (Tether)

Tether has appointed KPMG, one of the Big Four accounting firms, to perform a proper audit of its USDT stablecoin. Additionally, according to the Financial Times, Tether has also enlisted PwC, another of the Big four, to help prepare its internal systems for this auditing process. This initiative coincides with Tether’s plans to register USDT under the U.S. GENIUS Act, signaling a significant step in its expansion efforts within the U.S. market. [Tether]

Western Union has Big Plans for Stablecoins (American Banker)

Western Union is making a strategic pivot toward stablecoins as part of the 175-year-old company’s efforts to transform into a digital-first organization. The company’s own stablecoin — the U.S. Dollar Payment Token (USDPT), issued on the Solana blockchain and managed by U.S. Bank — will convert “negative float” (capital costs from pre-funding partners) into interest-bearing revenue. Beyond revenue generation, USDPT gives Western Union programmable compliance controls across its operations in 200 countries and territories, allowing transaction terms to be customized at the partner level. The stablecoin is also expected to help customers in inflation-prone economies hold dollar-denominated assets. [American Banker]

GSMA State of the Industry Report on Mobile Money 2026 (GSMA)

The GSMA published its annual mobile money report showing that mobile money has entered a new scale and maturity phase, processing over 2.1 trillion dollars annually through 2.3 billion registered accounts in 2025. The report documents rapid growth in active usage, merchant payments, interoperable bank–wallet transfers, and agent networks that digitize cash at volume. Mobile money now underpins basic account ownership in many low‑ and middle‑income countries, shifts payments from cash to digital channels, and increasingly delivers adjacent services such as nano‑credit, savings, and insurance, with most providers profitable. It also raises design questions around interoperability, cross‑border data rules, taxation of transactions, consumer protection, fraud controls, and persistent gender gaps in account use. [GSMA]

Final Report of the Consultation on CBDC for Uganda (BOU)

[June 2025] The Bank of Uganda (BOU) published the final report on its central bank digital currency (CBDC) consultation. It argues that a CBDC merits further, phased exploration as a tool for modernizing payments, inclusion, and regional integration. The survey of 151 largely domestic, policy‑adjacent stakeholders found high reported trust in a CBDC, strong expectations of reduced cash‑handling costs and improved payment efficiency, and majority support for a retail, potentially programmable instrument that coexists with current systems. For policy and institutional design, the report frames CBDC as building on Uganda’s extensive mobile money and real-time gross settlement (RTGS) infrastructure, potentially enhancing transparency, cross‑border trade in the East African Community, and monetary policy implementation, while emphasizing preconditions around legal frameworks, cybersecurity, and stakeholder engagement.

European Council Presses Co-Legislators on Digital Euro Legislation (European Council)

At its meeting on March 19, 2026, the European Council, the body comprising the heads of state or government of all European Union (EU) Member States, called on the EU’s two co-legislators, the European Parliament and the Council of the European Union (comprising Member State ministers), to conclude negotiations on the digital euro legislative proposal by end-2026. Although the European Council sets political direction and cannot itself pass legislation, its conclusions carry considerable authority. The deadline is consequential: the ECB has indicated that, assuming the regulation is adopted in 2026, pilot transactions could commence by mid-2027 and a first issuance could occur by 2029, with estimated development costs of approximately €1.3 billion. The ECB’s final decision on whether to issue a digital euro remains contingent on adoption of the enabling legislation. [European Council]

The first two papers below were authored by my two friends, Joachim Samuelsson and Ulrich Bindseil, who will also be speaking at this Thursday’s Digital Euro Conference (see below) in Frankfurt. Also, Joachim very kindly helped me to summarize both articles, which I greatly appreciated as I’ve been very tied up in other matters these past few weeks.

Offline Payments at Scale as Digital Money (Crunchfish)

Crunchfish published an executive white paper that reframes offline payments from a resilience add-on to ledger-based payments platforms to core payments infrastructure. In a fully digital economy, the absence of offline capability becomes a systemic vulnerability, but the architecture matters. The paper provides an analytical framework for evaluating offline models as a lens for institutional alignment. It distinguishes between immediate offline (which shifts value and risk to devices), deferred offline (preserves ledger money but introduces credit and reconciliation risk) and governed offline (reservation-based in which funds remain reserved at source, enabling offline execution with deterministic settlement). The governed offline model aligns with card pre-authorization and smart contract settlement. In the case of central bank digital currency (CBDC) it maintains central bank control offline, preserves singleness of digital money and avoids fragmentation. [Crunchfish]

Public Discourse on Retail Payments and the Case of CBDC (Ulrich Bindseil)

Ulrich Bindseil posted a white paper that analyzes retail payments as a network industry shaped by strong incentives to influence public opinion and regulation. Due to network effects, high fixed costs, and path dependence, multiple architectures can deliver similar outcomes while redistributing value across stakeholders. The paper maps how banks, card schemes, Bigtechs, merchants, consumers, crypto actors, and public authorities promote strategic narratives, creating a noisy and biased policy debate. It evaluates central bank digital currency (CBDC) as a central policy choice, alongside alternatives such as regulation or public instant-payment systems. One of the paper’s key insights is that retail payment outcomes are not determined purely by efficiency, but by strategic communication, political economy, and institutional design under uncertainty. In addition, effective policy requires independent analysis, transparency, and preserving a balance between public and private money. [SSRN]

Stablecoins and the Future of Payments: Evidence from Financial Markets (IMF)

The IMF published a working paper that argues that recent U.S. stablecoin legislation is interpreted by markets as a major pro‑competitive shock to the payments industry. Using high‑frequency stock‑price data around key votes on the Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act, they estimate that passage reduced incumbent U.S. payment firms’ aggregate market capitalization by about 18% (roughly $300 billion) once anticipation is accounted for, with larger losses for cross‑border specialists and smaller or no losses for firms protected by strong network effects or already offering crypto services. The authors infer that investors expect regulated, fully backed “payment stablecoins” to materially intensify competition—especially in cross‑border payments—while leaving open how far network incumbency and early crypto engagement will mitigate disruption over time.

Bermuda’s Premier Lays Ground for Digitally Native Dollar (Royal Gazette)

Bermuda’s Premier David Burt reportedly signaled a shift from the Government’s earlier strategy of relying solely on privately issued stablecoins toward exploring a digitally native Bermuda dollar, saying pilots and growing experience with stablecoin-based payments have prompted reconsideration of a public-sector role in issuance. He framed the prospective digital Bermuda dollar as a complementary, local instrument aimed at reducing friction in P2G transactions and strengthening monetary identity in a dollarized economy, noting that the Bermuda Monetary Authority and Ministry of Finance are now aligned on a legislative roadmap and beginning to evaluate infrastructure partners. While current stablecoin pilots continue and officials are examining whether such tokens could be accepted as legal tender, Burt emphasized that a future digital Bermuda dollar “may not be privately issued stable coins,” underscoring concerns that have been raised about consumer protection, dependence on private issuers, and the resilience of an “onchain” economy.

Bank of Korea Launches Full-Scale Implementation of “Project Han River” Phase 2 (BOK)

The Bank of Korea (BOK) announced Phase II of Project Hangang. It aims to trial large-scale, won-pegged deposit tokens built on a wholesale central bank digital currency (CBDC) layer, to cut transaction costs for both major corporations and small merchants burdened by credit card fees, building on Phase I’s system build out and 2025 live pilot. Participating banks will expand from 7 to 9 and merchant coverage will be significantly broadened. Phase II will test person to person transfers, biometric authentication, and automatic deposit token funding and sweep out. It will also deepen programmability, using digital vouchers in blockchain based treasury pilots such as an electric vehicle (EV) charging infrastructure project, and continue experiments with AI agent payments and tokenized bonds and equities. The 2026 agenda includes support for government treasury execution, and external consulting on regulation and operating models, with a Phase III vision of low cost universal payments, programmable financial services, and infrastructure for Korea’s broader digital asset ecosystem. [BOK]

ECB Calls for Experts to Participate in Digital Euro Rulebook Development (ECB)

The European Central Bank (ECB) launched a call for experts to join two workstreams under the digital euro Rulebook Development Group (RDG) to support further development of the digital euro scheme rulebook, which will set common rules, standards and procedures for using the digital euro across the euro area. One workstream (G5) will focus on implementation specifications for ATMs and payment terminals, including communication technologies, integration of offline digital euro functionality and leveraging existing standards, requiring expertise in ATM and terminal interfacing or provision. The other (B1) will design a certification and approval framework for testing and certifying payment and acceptance solutions and infrastructure used by payment service providers in the digital euro ecosystem, requiring expertise in payments and acceptance devices. The ECB notes that the flexible draft rulebook will be updated to reflect the outcome of the EU legislative process, with any decision to issue a digital euro to follow only after legislation is adopted. [ECB]

ECB Workshop on Pontes Platform Decentralized Programmability (ECB)

The ECB published an updates to its Pontes project aimed at enabling the settlement of distributed ledger technology (DLT) transactions using central bank money (CeBM). Pontes is the near-term DLT-based interoperability solution linking DLT platforms with TARGET Services so DLT transactions settle in CeBM, using API-based trigger and hash-link mechanisms and dedicated DLT cash wallets funded from TARGET accounts. The update focused on a workshop on market-developed smart contracts deployed by national central banks on the Eurosystem DLT (“decentralized programmability”) that would enable cash-locking for delivery-versus-payment, programmable payments, microtransactions, DLT interoperability, and automated corporate actions. [ECB]

Consultation on the Eurosystem’s Appia Project (ECB)

The ECB also published an update to its Appia project aimed at enabling the settlement of DLT transactions using CeBM. Appia is the longer-term initiative to provide tokenized CeBM for DLT-based wholesale markets via a unified settlement ecosystem. The update concerns the launching a formal consultation inviting market and public authorities to comment on Appia’s proposed DLT‑based wholesale ecosystem design and six‑block workplan via a structured questionnaire due 22 April 2026. Feedback will shape standards, governance choices, cross‑border linkages, and prioritization of analytical and practical work toward a 2028 blueprint. [ECB]

SEC Approves Nasdaq’s Securities Tokenization Plan (SEC)

The U.S. Securities and Exchange Commission (SEC) approved a Nasdaq rule change allowing certain listed securities to clear and settle in tokenized form via a Depository Trust Company (DTC) tokenization pilot. The order authorizes trading tokenized versions of large-cap equities and major index exchange-traded funds (ETFs) on the same order book, with identical CUSIP, symbol, rights, and execution priority as traditional shares, with tokenization preferences expressed through an order flag and implemented post‑trade by DTC. This embeds distributed-ledger-based entitlements within existing exchange, clearing, and surveillance infrastructures, preserves T+1 settlement, and treats tokenized and traditional shares identically for fees, market data, and audit trail. The SEC frames the decision as technology‑neutral, while leaving broader questions about alternative tokenization models, issuer choice, and future non‑fungible tokenized instruments to subsequent rulemakings. [SEC]

Zero-Knowledge Proof Authentication for Offline CBDC Payments (arXiv)

Santanu Mondal and T. Chithralekha propose a hybrid offline central bank digital currency (CBDC) architecture that uses zero-knowledge proofs (ZKPs) and secure hardware to enable cash-like payments on resource-constrained internet of things (IoT) devices while preserving regulatory oversight. The system combines a two-tier CBDC model with hierarchical “main wallet / IoT sub‑wallets,” secure elements and trusted execution environments for tamper-resistant key storage and counters, and NFC/BLE device-to-device transfers backed by lightweight ZKPs. This operationalizes intermittently offline CBDC designs, translating privacy-preserving anti–money laundering and counter–terrorist financing rules into on-device limits and ZKP circuits rather than continuous online monitoring, thereby shifting supervisory leverage into protocol and hardware design choices. Unresolved are empirical tradeoffs among proof complexity, device diversity, and real-world performance under regulatory stress scenarios. [arXiv]
