QuadrigaCX
The business, the turning points, and the decisions behind them.
01 / WHAT IT BUILT
What the company did
QuadrigaCX was a Vancouver-based Canadian cryptocurrency exchange, launched on Boxing Day 2013 by founder and CEO Gerald Cotten. At its peak it processed an estimated 60% to 90% of Canada's digital-currency exchange volume, letting users buy, sell and store cryptocurrencies as well as deposit fiat currency. It had 363,000 registered users and about 15 employees.
02 / QuadrigaCX FAILURE REASONS
Why it failed
QuadrigaCX's collapse was driven by founder fraud enabled by total lack of controls: Gerald Cotten was the only person with access to the exchange's offline 'cold wallets', and when he died in India on December 9, 2018 (complications from Crohn's disease), the company said $137 million USD in cryptocurrency belonging to an estimated 115,000 users was locked away. Court-appointed monitor Ernst & Young later found the cold wallets almost empty - Cotten had mixed QuadrigaCX funds with his own finances, transferred user funds off the exchange and used them as margin-trading collateral on other platforms. Crypto-boom growth in 2017 had stretched the young company's operational limits, and it had long relied on third-party payment processors after struggling to get Canadian bank accounts.
03 / EVENT HISTORY
Events in the structured record
- Launched
QuadrigaCX launched on Boxing Day 2013, founded by Gerald Cotten.
- Boom
The 2017 crypto boom drove a surge in trading volume, stretching the startup's operational limits; it processed 60-90% of Canadian digital-currency exchange volume.
- CEO death
On December 9, 2018, CEO Gerald Cotten died in India from complications of Crohn's disease; he was the sole holder of the cold-wallet keys.
- Protection and bankruptcy
On January 14, 2019, the death was announced; the exchange went offline January 31 and filed for creditor protection (CCAA) in Nova Scotia with Ernst & Young as monitor, claiming $250 million CAD (~$190M USD) owed to 115,000 users. On March 1, EY revealed the cold wallets were almost empty; in April 2019 the court moved the case into formal bankruptcy proceedings with EY as trustee.
- Forensic findings
EY's June 2019 report alleged Cotten transferred user funds off the exchange and used them as security for his own margin trading; investigators found dozens of fake accounts and commingled business/personal finances.

05 / AFTERMATH
Lessons
- No single person should be the only one who can access customer assets: key-person risk became total loss when the sole key-holder died.
- Client funds must be segregated and independently audited: QuadrigaCX's commingling of business and personal finances enabled years of fraud that only surfaced in bankruptcy.
