Gate has introduced a Proof of Security framework designed to measure how much of its customer exposure could theoretically be covered by assets kept outside hot wallets. According to the exchange’s official PoSEC disclosure, Gate reports a 104.58% cold-storage coverage ratio under its methodology, based on a November 4 storage snapshot showing 88.26% of platform assets in cold storage and 11.74% in hot wallets.
The metric extends beyond conventional Proof of Reserves, which focuses on whether an exchange reports sufficient assets against customer balances. PoSEC instead asks whether assets classified as cold storage would be sufficient to cover user assets if the entire hot-wallet balance were lost. Gate includes offline crypto as well as qualifying traditional assets held under independent custody and subject to isolation, multi-party authorization and independent verification requirements.
Different Snapshot Dates Limit the Headline Ratio
The 104.58% figure requires an important methodological caveat. Gate calculates it by comparing its 88.26% cold-storage share with a 84.39% user-asset share derived from its reserve structure. However, those percentages come from different snapshots and different asset totals, something Gate explicitly discloses on the PoSEC page. Price changes and asset movements between the two measurement dates are not reflected in the comparison.
Gate’s latest Proof of Reserves was taken on October 18 and reported $8.689 billion in platform assets against $7.333 billion in customer net balances, producing an overall reserve ratio of 118.49% and approximately $1.36 billion of excess reserves. Those dollar balances cannot simply be combined with the November 4 cold-storage percentage to calculate a same-date dollar security buffer. A common-date test would require customer liabilities and surviving cold assets to be valued under the same reporting perimeter and at the same point in time.
That distinction has become more relevant after recent exchange breaches demonstrated how quickly hot-wallet losses can become balance-sheet problems. Binance, for example, used corporate resources and its SAFU reserve to rebuild asset backing after its $6.3 billion breach. PoSEC attempts to quantify a different defense: how much customer exposure could theoretically remain covered without first replacing assets lost from online wallets.
Independent Verification Remains Pending
Gate says an independent third-party audit firm is reviewing the current PoSEC data, including asset authenticity and control, valuation methodology and the calculation of the coverage ratio. The company plans to publish the resulting report when the review is complete. Until then, the 104.58% ratio remains a Gate-reported security metric rather than an independently published assurance conclusion.
PoSEC also measures only one part of exchange security. Large reserves and substantial cold storage do not independently establish the strength of signing systems, employee access controls, withdrawal infrastructure or incident response. Recent cases such as the Mercado Bitcoin breach and subsequent asset-replenishment process demonstrated that exchange solvency, wallet architecture and operational containment are related but distinct controls.
The same separation applies after customers begin moving assets. When Binance reopened withdrawals and recorded more than $7 billion in tracked outflows, reserve backing and withdrawal resilience became separate observable tests. A cold-storage ratio can describe where assets are held, but it does not alone establish whether an exchange can process a sudden liquidity event safely and continuously.
Gate’s new framework therefore adds useful disclosure around storage architecture while leaving its strongest claim dependent on methodology and independent verification. The more decisive evidence will come when Gate publishes the third-party report and, ideally, aligns cold-storage assets and customer liabilities within the same valuation date and reporting perimeter.
