Tether invested in Orionx 15 months ago. The Chilean exchange is now shutting down permanently after a forensic audit found more than $7 million in customer assets recorded in its internal ledgers but missing from its own wallets, and two former executives are facing criminal complaints. The gap covers bitcoin, ether, XRP and Polygon's POL.
The timeline is brutal. On Sept. 2, Orionx filed a criminal complaint with Chilean prosecutors accusing former General Manager Roberto Zibert and former Technology Manager Joaquín Díaz of unfair administration, alleging an account linked to Díaz received over $1.5 million across 14 transfers and another wallet received 187 ETH, more than 4.1 million USDT and 200,000 USDC directly from Orionx addresses, with the questioned transactions stretching from 2018 to 2022. On Sept. 3, the exchange announced its definitive closure. Both executives reject the accusations and say the cause of the custody deficit has not been established. On Sept. 4, Chile's Financial Market Commission confirmed Orionx was never authorized under the Fintech Law, having had its license application rejected on June 19, which forced the wind-down. Customer withdrawals are suspended, and Orionx says it cannot guarantee full recovery.
"Important information: Today Orionx announced the start of a definitive closure of its operations." — Orionx (@orionx), September 3, 2026
The gap proof-of-reserves was never built to catch
The mechanism matters more than the scandal. This was not an on-chain exploit. It was an internal database claiming balances that company-controlled wallets could not verify, allegedly for years, the exact failure mode that quarterly proof-of-reserves snapshots cannot detect because those snapshots compare published claims against the same internal records. The parallel to the Pocket Bitcoin data breach and Rain's $1.1M card exploit is uncomfortable: Latin America's regulated-adjacent exchanges keep failing in ways their compliance marketing never covered. Chile's transitional Fintech Law regime let Orionx operate while unlicensed for years, and the CMF, which rejected the application in June, holds no legal authority to enforce asset restitution. Customers' only route is the criminal case and whatever restitution process Orionx assembles.
The due diligence question Tether has to answer
Then there is the investor. Tether led Orionx's Series A in June 2025 to expand stablecoin payment rails across Chile, Peru, Mexico and Colombia, terms undisclosed, and presumably with some diligence behind it. If the alleged transfers date to 2018 through 2022, the question of what a forensic review would have found in 2025 is now public, and it is a question every venture investor in regional exchanges will face after this. Tether has not commented publicly on the closure at the time of writing.
For users, the takeaway is structural, not personal. No regulator, no restitution fund, no segregated custody requirement existed between Orionx and its customers, and the allegations, which remain unproven in court, describe a slow bleed that audits and licensing both missed. Watch the criminal docket in Santiago: if prosecutors trace the flagged wallets and recover assets, Chile gets a template for exchange collapse. If not, 5,000-plus customers learn what unsecured creditors of an unlicensed platform already know. Either way, the next LATAM exchange claiming your trust should expect to be asked one question first: where exactly are the coins, and who verified it?
