Cryptocurrency exchange Coinbase has reassured customers that its systems and funds remain secure following the recent Binance hot wallet incident.
According to the company’s statement, Coinbase was not affected by the incident and continues operating normally.
The exchange emphasized that more than 99% of customer assets are held in cold wallets, keeping the vast majority of funds away from internet-connected storage systems.
The Coinbase cold wallet security approach is designed to reduce exposure to online threats, including unauthorized access and wallet-related attacks.
Cold wallets generally remain disconnected from the internet, making them harder for remote attackers to access.
Meanwhile, hot wallets remain connected to online systems and are commonly used to process customer deposits and withdrawals.
Coinbase explained that its hot wallet balances are dynamically adjusted based on customer activity.
This allows the platform to maintain liquidity for transactions while limiting the amount of cryptocurrency held in internet-connected wallets.

The Coinbase cold wallet security framework includes several layers of protection intended to prevent unauthorized asset transfers.
According to Coinbase, these safeguards include distributed keys, withdrawal limits, anomaly detection and emergency controls.
Distributed keys help reduce reliance on a single point of authorization.
Withdrawal limits can restrict the amount of cryptocurrency transferred within specified conditions.
Anomaly detection systems are designed to identify unusual transaction patterns that may indicate suspicious activity.
The exchange also highlighted emergency switches capable of pausing transaction signing when potential security threats are detected.
These measures are intended to provide additional protection during unexpected incidents.
However, no security system can eliminate every possible risk.
Cold storage reduces certain online attack risks, but exchanges must still manage operational, custody and internal security challenges.

Beyond its security measures, Coinbase also addressed how customer funds are managed.
The exchange stated that customer assets are held on a 1:1 basis, meaning the platform maintains assets corresponding to customer holdings.
Coinbase further emphasized that customer assets remain customer property.
According to the company, these assets are not lent out or used for other purposes unless customers provide instructions.
This distinction is particularly important for cryptocurrency investors concerned about how centralized exchanges manage deposited funds.
The statement comes as security practices across major trading platforms face renewed attention following the reported Binance hot wallet incident.
Coinbase’s response focuses on reassuring customers about its custody arrangements and internal controls.
Still, the company’s statements should not be interpreted as an independent audit of its current reserves or security systems.
For now, Coinbase says its cold storage strategy, layered security controls and 1:1 asset holdings continue to protect customer funds.
