Questions about the safety of funds held on centralized exchanges have resurfaced following one of the crypto industry’s most alarming security incidents. As investors reassess the risks of keeping their holdings on trading platforms, Coinbase, America’s largest cryptocurrency exchange, is moving to reassure customers that its security measures make it harder for a similar breach to occur on its platform.
The platform is highlighting a key part of its protection strategy, disclosing that more than 99% of customer assets are kept in cold storage, with only a small fraction exposed to online systems. The disclosure offers a glimpse into how Coinbase approaches asset protection amid heightened scrutiny of exchange security.
How Coinbase Protects Customer Assets With Multiple Security Layers
Coinbase says its approach to safeguarding customer funds goes beyond simply keeping most holdings offline. The exchange maintains that over 99% of customer assets are stored in cold wallets, while distributed private keys, withdrawal restrictions, and systems designed to detect unusual activity provide additional layers of protection against unauthorized transactions.
In a blog post published Wednesday, Coinbase also clarified that it was not impacted by the Binance security incident. The exchange emphasized that customer holdings are maintained on a 1:1 basis and remain the property of their owners. It added that these assets are neither lent out nor used without customer authorization.
Beyond its cold-storage strategy, Coinbase outlines several additional security measures designed to give customers greater control over their accounts. According to its security page, the exchange supports two-factor authentication and hardware security keys, while its Coinbase Vault feature adds another layer of protection by allowing users to require multiple approvals before withdrawals can be completed.
Coinbase stressed that security remains an ongoing priority as emerging technologies reshape the threat landscape. The exchange said its responsibility is to keep “improving safeguards” and “continuously monitor for threats” to protect customers. It also pointed to the rapid advancement of AI, noting that it is changing the security environment and making continued investment in “best-in-class security innovation” increasingly important.
Coinbase also maintains a separation between customer holdings and its own corporate assets, reinforcing the distinction between funds belonging to users and those controlled by the company. In its latest quarterly filing, the exchange disclosed that its platform held approximately $377 billion in assets. By comparison, Coinbase reported $8.6 billion in corporate cash and another $2.2 billion in crypto assets held on its own balance sheet.
Coinbase’s statement comes days after the October 29 Binance heist , which saw approximately $6.34 billion in cryptocurrency stolen from the exchange’s internet-connected hot wallets. In an update posted Wednesday, Binance announced that it had replenished 98% of the affected assets using its own funds. The exchange also expanded its proof-of-reserves coverage to include 44 cryptocurrencies, highlighting its efforts to reassure customers about the security and backing of their holdings.
In a separate incident, Brazilian cryptocurrency exchange Mercado Bitcoin also suspended withdrawals following a reported $45 million hack , adding to growing concerns about the security of centralized trading platforms.
