Upbit Eliminates Hot Wallet Risks by Shifting to Cold Storage

The cryptocurrency exchange Upbit has announced a significant shift in its asset management strategy, aiming to reduce the percentage of user assets stored in hot wallets to zero. This move comes after the exchange experienced a breach that resulted in the loss of over $30 million. The decision reflects Upbit’s commitment to enhancing security and protecting user assets.

The Transition Towards Cold Wallets

Previously, Upbit maintained a high concentration of deposited crypto-assets in cold wallets. However, recent developments have prompted the company to move all user funds into these more secure storage facilities. As of October 2025, an impressive 98.33% of crypto-assets were already held in cold storage, surpassing South Korea’s regulatory requirement of at least 80%.

Why Choose Cold Wallets?

Cold wallets offer enhanced security compared to their hot counterparts by storing assets offline, away from potential cyber threats. This strategic shift aligns with Upbit’s goal to safeguard user investments against increasing online vulnerabilities.

A Response to Cybersecurity Threats

This change in policy follows a severe breach involving Upbit’s hot wallet in November 2025, allegedly linked to the notorious Lazarus Group from North Korea. Such incidents underscore the need for robust security measures within crypto exchanges.
Upgrading Security Systems
In response, Upbit underwent a comprehensive review and restructuring of its wallet system. By transitioning exclusively to cold storage, Upbit not only enhances its security framework but also sets a new standard within the industry.

The Leadership Perspective

O Kyeong-sok, CEO of Dunamu (the operator behind Upbit), underscored that protecting users is paramount. This strategic pivot towards cold storage illustrates how seriously they take this responsibility.

Broader Implications for the Crypto Market

Upbit’s proactive stance may influence other exchanges facing similar cybersecurity challenges. As more platforms adopt stringent measures like those introduced by Upbit, users can expect increased safety and trust within the cryptocurrency ecosystem.
In conclusion, Upbit’s transition aims not only at mitigating risks but also at fostering confidence among its users through improved security practices. By prioritizing cold storage solutions over vulnerable hot wallets, Upbit sets a precedent for others in enhancing digital asset protection amidst rising cybersecurity threats.
