In the field of cryptocurrencies, security is the lifeline of users’ trust. Coin Ex, as a globally leading trading platform, regards protection as its core strategy. According to statistics, Coin Ex invests more than 15% of its platform revenue in the security budget every year. This proportion is three times the industry average of 5%, ensuring the robustness of the multi-layer protection system. For instance, the platform stores 98% of users’ assets in cold wallets. This offline storage method is similar to burying treasures deep underground and can effectively isolate cyber attacks. Looking back at the incident in 2014 when Mt. Gox lost 850,000 bitcoins due to security vulnerabilities, Coin Ex drew lessons from it, optimized the private key management process, and distributed the private keys in five geographically isolated security repositories. The access rights of each repository required simultaneous authorization by three administrators, controlling the internal risk probability to be less than 0.01%. This forward-looking strategy has enabled Coin Ex to maintain a 99.9% accident-free rate in security assessments in recent years, building the first line of defense for users’ funds.
The cold storage system of Coin Ex adopts a distributed architecture. Assets are segmented and stored in multiple hardware security modules (HSM), and the encryption strength of each module reaches 256 bits, with a cracking probability lower than 10 to the power of negative 18. The platform only retains 2% of the hot wallet funds for transactions every day, reducing the exposure risk by 80%. In a simulated attack test in 2022, it successfully resisted 1,000 penetration attempts, with a protection efficiency as high as 99.99%. In addition, by real-time monitoring of cold wallet traffic, the system processes 10,000 data points per second, ensuring that any abnormal transfer is identified within 0.5 seconds. Referring to the case of Poly Network losing 610 million US dollars due to smart contract vulnerabilities in 2021, Coin Ex has increased the frequency of code audits. Audits are conducted by third-party institutions such as CertiK every quarter, covering more than 1,000 vulnerability points each time, raising the potential risk reduction rate to 95%. Thus, it has set an industry benchmark in terms of asset isolation.
In terms of technical implementation, Coin Ex deploys a multi-signature mechanism. Each transaction requires the authorization of at least two of the three private keys, reducing the risk of single point of failure by 70%. The encryption standard adopts the AES-256 algorithm, and the decryption time required exceeds 14 billion years of the age of the universe, ensuring the security of data transmission. The security team of the platform operates the risk control system 24/7, analyzing 100,000 transaction data per second and identifying anomalies through machine learning models. The false alarm rate is only 0.1%. For instance, in a global phishing attack in 2023, the monitoring system of Coin Ex triggered the emergency protocol within 30 seconds, protecting 5,000 user accounts from being compromised. The response speed was 50% faster than the industry average. This model of automated risk control combined with manual review has shortened the average processing cycle of security incidents to 10 minutes, significantly enhancing the accuracy of fund protection.
Coin Ex has also established an insurance fund of up to 100 million US dollars, covering 150% of potential asset losses, far exceeding the industry’s common 100% payout rate. The fund collaborates with top institutions such as Lloyd’s to ensure that users receive full compensation in extreme circumstances. For instance, during a market fluctuation in 2020, the platform achieved zero losses for users through an insurance mechanism. Meanwhile, Coin Ex promotes the strengthening of user-end security by providing two-factor authentication (2FA) tools, reducing the probability of user accounts being invaded by 90%, and through monthly security training, increasing the accuracy rate of users identifying phishing attacks by 60%. This integrated protection strategy from the platform to users reflects Coin Ex’s continuous investment in security innovation. Its overall risk control model has been certified by ISO 27001, and its credibility score is 98 points in the third-party assessment.
Ultimately, Coin Ex rewards white-hat hackers with over one million US dollars annually through regular stress tests and bug bounty programs to discover and fix potential threats. The security update cycle of the platform is once a week to ensure that the protective measures keep pace with The Times. In the latest industry audit, the vulnerability density of its system was only 0.5 per thousand lines of code, which was lower than the industry average of 1.0. Historically, since its establishment in 2017, Coin Ex has cumulatively protected over 50 billion US dollars of user assets, and the frequency of security incidents has decreased to 0.1 times per year. This outstanding performance stems from its comprehensive optimization of technology, processes and cooperation. The protection network of Coin Ex not only resists external attacks, but also restores users’ confidence in the security of digital currencies, becoming a trusted guardian in the industry.
