The stablecoin landscape is undergoing significant shifts, marked by Tether’s introduction of a new self-custodial wallet, Circle’s robust defense of its policy on freezing stolen USDC, and a critical assessment from the U.S. Federal Reserve questioning the real-world payment utility of these digital assets. Simultaneously, traditional financial behemoth Visa is deepening its involvement in the blockchain space through strategic partnerships, while the International Monetary Fund (IMF) continues to scrutinize the systemic risks and stability mechanisms of stablecoins. These developments collectively highlight the intricate balance between innovation, regulatory oversight, and the ongoing struggle to define the practical application and legal frameworks for stablecoins.
Tether’s Strategic Wallet Debut: "The People’s Wallet"
On April 14, Tether, the issuer of the world’s largest stablecoin USDT, announced the launch of tether.wallet. Dubbed "The People’s Wallet" by CEO Paolo Ardoino, this self-custodial tool aims to simplify access to digital assets for billions of users worldwide, particularly those underserved by traditional financial systems. The initiative represents a strategic move to extend Tether’s global financial infrastructure directly to end-users, bypassing some of the technical complexities often associated with cryptocurrency.
The new wallet, built upon Tether’s open-source Wallet Development Kit, is designed for ease of use. It supports a range of Tether’s dollar-backed stablecoins, USDT and USAT, its gold-backed XAUT, and Bitcoin (BTC). A key feature is the ability for users to send funds using simple, human-readable identifiers, such as email addresses, which is intended to mitigate common errors associated with lengthy, complex wallet addresses. Transactions within tether.wallet are locally signed on the user’s device before being broadcast to the network, and transaction fees are paid using the asset being transferred, eliminating the need for separate network-specific "gas" tokens.
Initially, tether.wallet supports USDT on Ethereum, Polygon, Plasma, and Arbitrum; USAT on Ethereum; XAUT on Ethereum, Polygon, Plasma, and Arbitrum; and BTC on-chain and via the Lightning Network. Tether has indicated plans for rapid expansion of supported networks within the next 30 days, promising "seamless swaps" and an "insane user experience." Paolo Ardoino emphasized the scale of Tether’s reach, claiming its technology is utilized by over 570 million people globally, with tens of millions of new wallets added each quarter, underscoring the potential impact of this new user-friendly interface.
USDT’s Unintended Use: Illicit Activities in South Korea
While Tether promotes broader adoption, recent reports from South Korea have cast a shadow on stablecoin usage, revealing a disturbing trend where USDT is being used as currency for illicit "revenge services." Earlier this month, South Korean media highlighted the emergence of "revenge agencies" advertising their services on platforms like Telegram. These agencies exploit the perceived anonymity of cryptocurrency and messaging platforms to offer a range of illegal activities, from petty harassment, such as smearing human feces on property or gluing door locks, to more severe threats, including causing "upper or lower body disabilities" or "accidental death."
Prospective clients are reportedly asked to make a 50% deposit in cryptocurrency, specifically Tether/USDT, with assurances that "clients cannot be traced thanks to Telegram and cryptocurrency." Police have initiated investigations and made arrests, including a suspected ringleader, but other groups appear undeterred, continuing to offer services ranging from "debt resolution" to "school violence resolution." This development underscores the persistent challenge stablecoin issuers face in preventing their tokens from being co-opted for criminal enterprises, despite efforts to enhance cooperation with law enforcement. Tether, in particular, has been working to improve its reputation and demonstrate compliance in combating illicit finance, a task made more complex by such incidents.
Circle Defends Its Stance on Freezing Stolen USDC
The issue of stablecoin issuers’ responsibility in combating illicit activity was further highlighted by recent criticism leveled against Circle, the issuer of USDC. The company faced scrutiny for its perceived slow response in freezing USDC tokens linked to a significant $285 million exploit of the Solana-based Drift Protocol by North Korean hackers. This incident reignited the debate surrounding the "code is law" ethos of decentralization versus the need for centralized intervention in cases of theft and fraud.
On April 10, Dante Disparte, Circle’s chief strategy officer, published a detailed response titled "When Open Systems Are Tested: Accountability, Rule of Law, and the Work Ahead." Disparte clarified that Circle’s decision to freeze USDC is not arbitrary but rather a "compliance obligation," exercised only when legally compelled by an appropriate authority through lawful process. He articulated the tension between those advocating for immediate freezing and those upholding the principle of "code is law," arguing that this tension is central to developing effective policy for crypto and open internet financial systems.
Circle CEO Jeremy Allaire echoed this perspective during a visit to South Korea, stating that it would be "a very risky proposition" for Circle to deviate from legal mandates and make unilateral decisions regarding asset freezes. He also revealed that Circle is actively working with U.S. lawmakers on the Senate’s digital asset market structure bill (CLARITY Act) to include a "safe harbor" provision for stablecoin issuers. This provision would grant issuers legal protection for taking preventative actions in specific circumstances, aiming to enable faster, more coordinated interventions while preserving property rights and privacy.
However, blockchain sleuth ZachXBT, a prominent critic of Circle’s handling of the Drift exploit, countered Allaire’s arguments, labeling them "a completely made up statement." ZachXBT pointed to Circle’s own terms of service, which explicitly state that Circle reserves the right, "in its sole discretion," to "block" or "freeze" certain USDC addresses determined to be associated with illegal activity. This discrepancy highlights the ongoing legal and ethical complexities faced by centralized stablecoin issuers operating within a decentralized ecosystem.
Circle’s Arc Blockchain and Proof-of-Stake Transition
Beyond regulatory debates, Circle is also advancing its technological infrastructure. During his South Korea visit, Jeremy Allaire announced memorandums of understanding (MoUs) with two of the country’s leading crypto exchanges, Bithumb and Upbit. While these MoUs are currently exploratory due to South Korea’s evolving digital asset legislation, they signal Circle’s intent to engage with the market. Allaire indicated that Circle is unlikely to issue a Korean won-backed stablecoin directly but would instead seek partnerships with local won issuers and consortiums of banks, fintechs, and crypto firms.
More significantly, Allaire confirmed Circle’s plans to issue a native token on Arc, the company’s "enterprise-grade, stablecoin-native" Layer-1 "economic operating system." This token is envisioned to provide mechanisms for governance, incentives, and economic alignment within the Arc ecosystem. Furthermore, Allaire revealed the long-term strategy to transition Arc into a proof-of-stake (PoS) consensus system. This move from a potential proof-of-work (PoW) or other initial design aligns Arc with a growing trend in the blockchain industry towards more energy-efficient and scalable consensus mechanisms. PoS networks rely on validators staking a specific amount of network tokens to participate in transaction validation, earning rewards in return, a model distinct from PoW’s competitive mining approach. Arc is currently in testnet, with a mainnet launch and beta version expected later this year.
Visa’s Deepening Engagement in the Stablecoin Landscape
Traditional financial powerhouses are increasingly integrating stablecoins into their operations, with Visa leading the charge. On April 14, Visa announced its role as an anchor validator on Tempo, the stablecoin-focused Layer-1 blockchain launched last year by payment processor Stripe. Tempo utilizes a Simplex consensus protocol that requires validators, and Visa joins Stripe and Zodia Custody by Standard Chartered as its initial external validators.
Cuy Sheffield, Visa’s head of crypto, emphasized that this move expands the company’s long-standing blockchain expertise by directly "running critical blockchain infrastructure ourselves," thereby supporting the development of stablecoin payment systems that meet stringent operational standards. Visa’s node was developed and managed in-house over six months, in collaboration with Tempo’s engineering team. Tempo GTM Nischay Upadhyayula praised Visa’s "operational rigor" and confirmed their role as a "design partner since day one."
Tempo’s mainnet went live last month, alongside its new Machine Payments Protocol (MPP), an open standard enabling programmatic payments for agentic AI and services. Visa has already extended MPP to support card payments on its network, showcasing practical application. This validator role on Tempo is part of Visa’s broader stablecoin strategy, which includes partnerships with companies like BVNK, Circle, Rain, and Reap. In March, Visa also announced its participation as a "super validator" on the Canton Network, a privacy-focused chain "built for regulated finance," backed by a consortium including Circle, Goldman Sachs, and BNY Mellon. Visa’s presence as one of approximately 40 super validators on Canton is expected to facilitate crypto-wary institutions in experimenting with and scaling stablecoin payments, settlement, and treasury use cases, ensuring compliance and risk management. Eric Saraniecki, Canton’s head of network strategy, views Visa’s participation as validation that the technology has matured beyond experimentation into production-ready infrastructure.
Federal Reserve Questions Stablecoin’s Payment Utility
Despite the ambitious visions of stablecoin proponents, the U.S. Federal Reserve Bank of Kansas City recently published a research briefing titled "What are Stablecoins used for Today?" which casts doubt on the widespread adoption of stablecoins for everyday payments in developed markets. Lead payments specialist Franklin Noll’s findings suggest that while "crypto boosters" often tout stablecoins as a payment revolution, actual payment usage (B2B, P2P) accounts for a mere 0.7% of all stablecoin activity, roughly $2 billion annually. This aligns with broader studies indicating that stablecoins’ primary use remains speculative trading pairs, with emerging markets showing slightly more adoption for store-of-value or cross-border remittances. Overall, stablecoin payment volume accounts for only about 0.02% of the global total.
Noll’s research indicates that "transfers" constitute the largest share of stablecoin use at 29.3%, primarily involving high-value movements into and out of Decentralized Finance (DeFi) protocols and internal treasury applications. Exchange-based activity follows at 26.4%, with "finance" (DeFi) contributing 17.2% and "infrastructure" (largely cross-chain bridges, highlighting interoperability issues) at 5.1%. These three categories combined account for over half of stablecoin functionality. A significant 21.2% of stablecoins are classified as "idle," held in rarely used wallets, forgotten, lost, or as small savings, potentially serving as de facto fiat-denominated savings accounts in regions with unstable national currencies.
Noll concludes that despite their potential for independent operation, the strong link between stablecoins and the broader crypto finance ecosystem makes them sensitive to market fluctuations, rising and falling with the volatile crypto market. This assessment from a major central bank underscores the regulatory skepticism surrounding stablecoins’ current utility and the need for more robust, widely adopted use cases beyond speculative trading.
IMF’s Blueprint for Stablecoin Stability and Run Prevention
The International Monetary Fund (IMF) has also weighed in on stablecoin stability, following its report on tokenized finance with a new working paper titled "Making Stablecoins Stable." The paper zeroes in on the critical need for "safe" fiat reserve assets underpinning stablecoins and the inherent trade-off between maintaining stability and incentivizing issuance. The IMF highlights the risk of "runs" on stablecoin assets, citing the March 2023 incident where Circle’s USDC temporarily de-pegged from the dollar to $0.87 after the collapse of Silicon Valley Bank (SVB), where Circle held $3.3 billion of its cash reserves.
To mitigate such risks, the IMF proposes three main options:
- Strict Reserve Requirements: Mandating issuers to hold "very safe and liquid assets."
- Loss-Absorbing Equity: Requiring issuers to hold "additional loss-absorbing equity" to weather unexpected shocks.
- Public Backstops: Providing "public backstops to ensure issuers can honor redemptions even in crisis times," which could include forms of deposit insurance, access to central bank liquidity facilities, and emergency lending.
These recommendations align with ongoing discussions, such as the U.S. Federal Deposit Insurance Corporation (FDIC)’s recommendations for implementing the GENIUS Act, which would make stablecoin issuers’ reserves eligible for deposit insurance, though not directly extending coverage to stablecoin holders. The IMF warns that the risk of insolvency increases when issuers hold riskier assets with unstable valuations, explicitly singling out Tether, whose December 2025 reserves reportedly included nearly $50 billion in non-traditional assets like gold, BTC, and "secured loans." This diversified, albeit riskier, reserve composition may explain Tether’s reported efforts to raise billions in cash from external investors to potentially de-risk its holdings.
The IMF also suggests that requiring issuers to hold "safe and liquid" central bank reserves, with remuneration, could boost revenue. However, this approach faces challenges, as exemplified by the U.K.’s proposal for issuers to hold 40% of reserves in unremunerated Bank of England accounts. Another revenue-generating idea, "data utilization" (selling transaction data), is also discussed, though the IMF notes it would likely face user resistance and favor larger providers due to economies of scale, potentially exacerbating market concentration. Given that Tether and Circle already command a combined 84% share of the stablecoin market, concerns about concentration are already pertinent.
These converging developments from market leaders, regulators, and international financial institutions underscore a pivotal moment for stablecoins. The industry is grappling with the tension between fostering innovation and ensuring financial stability, demonstrating a clear move towards greater scrutiny and the establishment of comprehensive regulatory frameworks to govern these increasingly influential digital assets.
