Digital Exchange Loses $137 Million As Founder Takes Passwords To the Grave

A cryptocurrency exchange in Canada has lost control of at least $137 million of its customers' assets following the sudden death of its founder, who was the only person known to have access to the offline wallet that stored the digital coins. British Columbia-based QuadrigaCX is unable to access most or all of another $53 million because it's tied up in disputes with third parties. Ars Technica reports: The dramatic misstep was reported in a sworn affidavit that was obtained by CoinDesk. The affidavit was filed Thursday by Jennifer Robertson, widow of QuadrigaCX's sole director and officer Gerry Cotten. Robertson testified that Cotten died of Crohn's disease in India in December at the age of 30. Following standard security practices by many holders of cryptocurrency, QuadrigaCX stored the vast majority of its cryptocurrency holdings in a 'cold wallet,' meaning a digital wallet that wasn't connected to the Internet. The measure is designed to prevent hacks that regularly drain hot wallets of millions of dollars. Thursday's court filing, however, demonstrates that cold wallets are by no means a surefire way to secure digital coins. Robertson testified that Cotten stored the cold wallet on an encrypted laptop that only he could decrypt. Based on company records, she said the cold wallet stored $180 million in Canadian dollars ($137 million in US dollars), all of which is currently inaccessible to QuadrigaCX and more than 100,000 customers. 'The laptop computer from which Gerry carried out the Companies' business is encrypted, and I do not know the password or recovery key,' Robertson wrote. 'Despite repeated and diligent searches, I have not been able to find them written down anywhere.' The mismanaged cold wallet is only one of the problems besieging QuadrigaCX. Differences with at least three third-party partners has tied up most or all of an additional $53 million in assets. Making matters worse, many QuadrigaCX customers continued to make automatic transfers into the service following Cotten's death. On Monday, the site became inaccessible with little explanation, except for this status update, which was later taken down. On Thursday, QuadrigaCX said it would file for creditor protection as it worked to regain control of its assets. As of Thursday, the site had 115,000 customers with outstanding balances.
