Tether-Backed Exchange Orionx Collapses Over $7M Custody Breach

Orionx, a Chilean crypto exchange backed by Tether, has announced it is shutting down permanently after a forensic audit uncovered more than $7 million in customer crypto assets that had been moved out of company custody into wallets the exchange does not control. The exchange has suspended all withdrawals and filed a criminal complaint against two of its former co-founders, Roberto Zibert and Joaquín Díaz, whom it accuses of orchestrating the transfers.

The collapse of a platform that had grown from a domestic Chilean retail exchange into a payments operation spanning Peru, Colombia and Mexico raises immediate and uncomfortable questions about who was actually watching customer funds — and why it took years to notice they were missing.

How the mismatch surfaced

According to the company, the discrepancy was flagged internally by COO Thomas Mac Millan on Aug. 27, during a broader review of Orionx’s operations undertaken to comply with Chile’s new Fintech Law. That regulatory push, rather than a customer complaint or a routine audit trigger, is what set the investigation in motion. The subsequent forensic review pointed to a pattern of transfers allegedly carried out between 2018 and 2021, long before Tether took a stake in the company.

Founded in 2017, Orionx secured a Series A round led by Tether in June 2025, a deal framed at the time as part of the stablecoin issuer’s broader push into Latin American crypto infrastructure. That investment came roughly 15 months before the shutdown announcement, and it means Tether’s due diligence — whatever form it took — did not catch a custody gap that had reportedly existed for years by the time the deal closed.

The numbers laid out by Orionx’s internal review are specific: more than $1.5 million allegedly funneled into an account linked to Díaz across 14 separate transfers, 187 ETH allegedly received by another wallet, and additional inflows of more than 4.1 million USDT and 200,000 USDC tied to the alleged scheme. Both accused former executives deny any wrongdoing, and the matter is now before Chilean authorities as a criminal complaint rather than a settled fact.

What it means for the region

Orionx’s failure lands squarely on the question of custody — the basic promise that when a customer deposits crypto on an exchange, the exchange actually holds it, one to one, rather than commingling it or allowing insiders to route it elsewhere. That promise has been tested repeatedly across the industry, and the fact that it broke down at a firm carrying Tether’s name and capital is notable. Tether has spent recent years positioning itself as more than a stablecoin issuer, building a portfolio of equity stakes across Latin American fintech and crypto ventures. Orionx’s implosion is a reminder that backing a company financially does not automatically fix, or even reveal, the internal controls that were already in place before the check was signed.

For Chilean and broader Latin American regulators, the episode arrives at an awkward moment. Chile’s Fintech Law was designed precisely to force exchanges to formalize custody, reporting and governance practices that had previously operated in a gray zone. That the law’s compliance review is what surfaced the missing funds is arguably a point in favor of the regulation — it worked, in the sense that it forced a look under the hood that had apparently not happened before. But it also means the mismatch survived seven years, two ownership eras, and a Tether-led funding round before anyone caught it through supervisory channels rather than internal foresight.

Customers across Chile, Peru, Colombia and Mexico who held balances on Orionx are now facing an indefinite freeze, with withdrawals suspended while the criminal case proceeds. The exchange’s decision to shut down entirely, rather than attempt a restructuring or partial resumption of services, signals that the hole in custodied assets was severe enough that management saw no viable path to continuing operations, at least under the current ownership and leadership structure.

What to watch next

The Chilean criminal complaint against Zibert and Díaz will be the central thread to follow, since any recovery of funds for customers likely depends on the outcome of that case and whatever assets can be traced and clawed back. Regulators overseeing the Fintech Law’s rollout will also be watched closely for whether they extend similar custody reviews to other exchanges operating in the country, given that Orionx’s own compliance check is what exposed the problem here. Tether’s public response, or lack of one, regarding its Series A stake and any responsibility toward affected customers is another open question worth tracking, as is whether the incident prompts closer scrutiny of Tether’s other regional investments. The episode also fits into a broader pattern of custody failures rattling confidence in self-custody and exchange-held crypto alike, echoed recently in reporting on the Coldcard wallet hack and in how exchanges elsewhere, such as Bithumb’s decision to delay its IPO for an internal control overhaul, have responded to similar governance pressures. Separately, Orionx’s exit from four national markets at once also underscores how quickly a regional platform can unwind once trust in custody breaks, a dynamic not unlike the market consequences seen when Bitget chose to exit Japan rather than meet tightened exchange rules.
