Santiago, Chile – Orionx, a prominent Chilean cryptocurrency exchange that had secured significant backing from USDt stablecoin issuer Tether, has announced its permanent closure following the discovery of a substantial multi-million dollar discrepancy linked to its asset custody systems. The exchange, which had positioned itself as a key player in Latin America’s burgeoning digital asset market, initiated the shutdown process after a forensic audit revealed that more than $7 million in client custodial assets had been illicitly transferred to wallets not under the company’s management. The abrupt closure has sent ripples through the regional crypto community, raising critical questions about security, regulatory oversight, and the inherent risks associated with centralized digital asset platforms.

The company formally disclosed its decision and the underlying issues in an announcement shared on X (formerly Twitter) on Thursday, stating its "sole priority now is to return as much of our clients’ assets as possible." In light of the unfolding crisis, all withdrawals from the platform have been temporarily suspended, leaving numerous clients in a precarious financial situation. This development is particularly striking given that it comes a mere 15 months after Tether, a global titan in the stablecoin market, led Orionx’s Series A funding round, signaling a strategic push to expand digital asset adoption across Latin America. The investment had been viewed as a major vote of confidence in Orionx’s potential and the broader regional market.

Unraveling the Custody Crisis: A $7 Million Discrepancy

The core of Orionx’s crisis stems from a critical failure in asset custody, a foundational element of trust for any financial institution, particularly in the volatile cryptocurrency sector. The exchange’s public statement, while confirming the closure and the financial shortfall, initially left several key details ambiguous, including the precise timing of the unauthorized transfers and the exact mechanism through which the discrepancy was first detected. However, subsequent reports, notably from the major Chilean newspaper La Tercera, citing the company’s criminal complaint, have shed more light on the sequence of events.

According to these reports, Orionx embarked on a comprehensive review of its operations in 2025, a proactive measure undertaken to ensure compliance with Chile’s evolving Fintech Law. This regulatory initiative, designed to foster innovation while safeguarding consumers and financial stability, mandates stringent operational and security standards for digital asset service providers. It was during this rigorous internal assessment that a critical red flag emerged. On August 27, 2026, Thomas Mac Millan, Orionx’s Chief Operating Officer, identified a "significant mismatch" between the balances recorded in the exchange’s internal systems and the actual assets held in its custody wallets.

This initial discovery triggered an immediate internal investigation, which soon escalated to the commissioning of an external forensic audit. The audit, leveraging specialized expertise to meticulously compare Orionx’s internal records with verifiable data on public blockchain ledgers, confirmed the worst fears. It definitively established that the assets recorded in Orionx’s systems substantially exceeded the digital assets actually held at its designated custody addresses. The audit specifically identified shortfalls across multiple major cryptocurrencies, including Bitcoin (BTC), Ether (ETH), XRP, and Polygon (POL), as well as stablecoins such as USDt (USDT) and USDC. The combined value of these missing assets was determined to be in excess of $7 million.

Further details emerging from the criminal complaint suggest a more protracted and systemic issue. The complaint reportedly alleges that the unauthorized transfers of assets out of Orionx’s custody did not occur recently but rather spanned a period between 2018 and 2021. This indicates a long-standing vulnerability or malicious activity that went undetected for several years, eventually culminating in the current crisis. The transfers allegedly routed funds to various external accounts, including those on other crypto platforms, complicating the tracing and recovery efforts.

Allegations Against Co-founders and Their Denials

In a dramatic turn, Orionx announced that it had filed a criminal complaint on Wednesday, prior to its public disclosure of the closure, directly implicating two of its co-founders and former executives: Roberto Zibert and Joaquín Díaz. The complaint alleges that these individuals had privileged access to the company’s critical crypto custody systems, placing them in a position to facilitate or directly execute the illicit transfers.

Specific details cited in La Tercera’s reporting indicate that an account associated with Joaquín Díaz allegedly received over $1.5 million across 14 separate transfers. Furthermore, another wallet reportedly received significant amounts of various cryptocurrencies from Orionx’s custody, including 187 Ether, more than 4.1 million USDt (USDT), and 200,000 USDC. These allegations paint a picture of deliberate and substantial misappropriation of client funds over an extended period.

In response to these grave accusations, both Roberto Zibert and Joaquín Díaz have vehemently denied any wrongdoing. In statements reported by local media, they asserted that they never acted against the interests of Orionx’s customers and maintained that the precise cause of the exchange’s asset shortfall remains unclear to them. Their categorical rejection of the charges sets the stage for a potentially protracted legal battle, with significant implications for all parties involved and the broader Chilean crypto ecosystem.

Tether’s Strategic Bet in Latin America and the Fallout

Orionx’s journey began in 2017, emerging from Chile to grow into a multifaceted digital asset platform. Beyond offering retail crypto exchange services, it expanded into crypto payment and other financial services, extending its reach across Chile, Peru, Colombia, and Mexico. Its growth trajectory attracted the attention of major industry players, culminating in Tether’s pivotal investment.

In June 2025, Tether, the issuer of the world’s largest stablecoin, USDt, exclusively led Orionx’s Series A funding round. This investment was a cornerstone of Tether’s broader strategy to foster digital asset adoption and infrastructure development across Latin America, a region identified for its high potential for cryptocurrency growth due to economic conditions and a tech-savvy population. Tether’s announcement at the time highlighted Orionx’s "visionary leadership and robust platform" as key reasons for its strategic investment. However, the original press release detailing this investment is notably no longer available on Tether’s official website, suggesting an attempt to distance itself from the unfolding scandal or to reassess its public position on the matter.

The closure of Orionx and the associated criminal allegations present a significant reputational challenge for Tether and its ambitions in Latin America. While Tether’s investment was strategic, it now faces questions regarding its due diligence processes and the oversight of companies it backs. For the wider Latin American crypto market, which has seen substantial growth and investment interest, the Orionx incident serves as a stark reminder of the inherent risks in a still-developing regulatory and operational landscape. It underscores the critical need for enhanced security measures, transparent financial practices, and robust regulatory frameworks to protect consumers and build long-term trust.

Cointelegraph reached out to both Tether and Orionx for official comments on the matter but had not received a response by the time of publication. The silence from Tether, while understandable given the ongoing legal complexities, will likely add to scrutiny from investors and the public.

Broader Implications for Crypto Custody, Regulation, and Client Trust

The Orionx saga highlights several critical vulnerabilities and challenges facing the global cryptocurrency industry. At its heart is the issue of asset custody. Centralized exchanges, by their very nature, require users to entrust their private keys and digital assets to the platform. This fundamental reliance necessitates absolute transparency, rigorous internal controls, and unassailable security protocols. The "not your keys, not your crypto" adage, a mantra among decentralized finance advocates, resonates strongly in the wake of such incidents, reminding users of the risks associated with third-party custody.

The alleged involvement of co-founders in the misappropriation of funds underscores the "insider threat" — a complex challenge even for well-funded and seemingly secure operations. It highlights the need for multi-signature authorization, strict access controls, regular third-party audits, and robust governance structures to prevent abuse of power and unauthorized asset movements.

Chile’s Fintech Law, which prompted Orionx’s operational review, is a testament to a growing global trend towards greater regulation of the digital asset space. While regulation aims to protect consumers and ensure market integrity, the Orionx case demonstrates that even proactive compliance efforts can uncover deeply rooted problems. The incident will likely accelerate calls for stricter enforcement, more frequent mandatory audits, and enhanced accountability mechanisms for crypto exchanges, not just in Chile but across jurisdictions seeking to regulate this nascent industry.

For the thousands of clients who entrusted their funds to Orionx, the immediate future is uncertain. With withdrawals suspended and the company prioritizing the return of assets, a lengthy and potentially complex recovery process is anticipated. The outcome of the criminal complaint against the former executives will be closely watched, as it could set important precedents for accountability in cases of alleged crypto fraud and mismanagement. The incident casts a long shadow over the promise of digital assets in Latin America, potentially eroding investor and user confidence and making it more challenging for legitimate crypto businesses to thrive in the region. The industry’s ability to learn from such failures and implement more resilient, transparent, and secure systems will be crucial for its long-term growth and mainstream acceptance.
