As of November 5, 2026, Coinbase cold storage is at the centre of crypto news today, after the exchange said October 29 breach did not touch it.
In ablog post published Wednesday, November 4, the firm said it keeps more than 99% of customer assets offline.
According toBinance’s incident update, about $6.34 billion in digital assets were impacted on October 29.
Binance said it will absorb the loss, and that 98% of affected token assets were replenished by October 31.
It also said its hot wallet used multi-party computation, so no single private key could revoke the malicious authorizations at once. That detail matters for crypto exchange security debates.
Coinbase answered on X, calling secure custody daily work. Theexchange’s X post lists 1:1 backing, audited financials, key splitting and no single point of failure.
The Block also covered this news in itstweet on X, summarising the same safeguards.
Is Coinbase safe after Binance hack? The firm says it was not affected by the breach.
Readers tracking the hack Coinbase angle should note this is a company statement, not an independent audit.
Are my funds safe on Coinbase? The core message is Coinbase customer funds safe, because assets are held 1:1 and remain customer property.
How much of Coinbase funds are in cold storage? The post says more than 99%. Does Coinbase keep crypto in cold storage?

Safeguard
What the exchange says
Cold storage
More than 99% of customer assets
Key protection
Distributed private keys
Transfer controls
Withdrawal limits, anomaly detection
Backing
1:1, customer property
The post names Coinbase distributed private keys, Coinbase withdrawal limits and anomaly detection as defences against unauthorized transfers. Coinbase 1:1 backing is the matching promise on customer funds backed 1:1.
Not without authorization, per the blog. Assets are not lent or used unless customers allow it.
Customer asset protection also leans on audited financials, according to the X post. Coinbase security, in the firm’s telling, is daily work, not a one-time achievement.
Both firms describe distributed key setups. They said its hot wallet used multi-party computation, yet the attack ran through on-chain authorizations.
Coinbase cold storage, by the firm’s account, keeps most assets offline, which could mean less exposure in a hot wallet.
That is a comparison of claims, and each exchange hack can follow a different path. They also said the entry points used in the attack have been closed.
Analysts following crypto news may read the blog as reassurance, not proof.
Coinbase cold storage at 99% describes where assets sit and cannot rule out every threat, such as a compromised signing process or a stolen credential.
Binance’s case suggests distributed keys alone did not stop its attack, so independent crypto custody disclosures may matter more to users.
Readers should watch for further verification.
