Upbit Raises Cold Storage Coverage to 99% of Customer Funds
On Dec. 10, 2025 Upbit announced it will increase the portion of customer deposits kept in cold storage from 98% to 99%, transferring an extra 1% of funds into offline wallets. The tweak is a straightforward risk-reduction step designed to shrink the exchange’s hot-wallet footprint and make customer assets less vulnerable to online hacks, while maintaining sufficient liquidity for normal withdrawals and trading operations.
The move underscores continuing industry emphasis on stronger custody practices after past exchange breaches and regulatory scrutiny. For users and institutional clients, the change should provide modest reassurance about asset safety; for the market, it signals Upbit’s commitment to operational security and may prompt peers to reevaluate their own custody mixes. Operational impacts are expected to be minimal, with the primary benefit being a reduced attack surface for cyber theft.
