🛡️ What is SAFU?
SAFU stands for Secure Asset Fund for Users. It is Binance's insurance fund, established in 2018 to protect users in the event of a security breach, hack, or other unforeseen incident. The fund holds over $1 billion in assets, making it one of the largest insurance funds in the cryptocurrency industry.
The term "SAFU" has become a cultural phenomenon in the crypto community. It's often used to refer to being safe or protected, and Binance's CEO, Changpeng Zhao (CZ), frequently reminds users to "stay SAFU."
SAFU is not just an acronym — it's a promise from Binance to its users. The fund ensures that even if the exchange suffers a security breach, users can be compensated for their losses.
⚙️ How SAFU Works
SAFU is funded, managed, and used in a transparent manner to protect Binance users.
Funding
SAFU is funded by a portion of Binance's trading fees. Binance allocates a percentage of the fees generated from trading on the platform to the SAFU fund. This ensures that the fund grows over time and is always available to protect users.
Management
- Transparency: Binance regularly publishes the size and composition of the SAFU fund.
- Cold Storage: The fund's assets are stored in cold storage for maximum security.
- Audits: The fund is regularly audited to ensure its integrity.
Usage
- Hack Compensation: If Binance suffers a security breach and user funds are compromised, the SAFU fund is used to compensate affected users.
- Operational Losses: The fund may also cover operational losses in certain circumstances.
- User Protection: The fund is designed to protect users, not the exchange itself.
Binance publishes the size of the SAFU fund on a regular basis. You can check the current fund size on Binance's official website or in their announcements.
📅 Why SAFU Was Created
SAFU was created in 2018 after Binance experienced a security breach. The exchange's response to the breach — fully compensating affected users using the newly established SAFU fund — set a new standard for user protection in the crypto industry.
The 2018 Incident

After the 2018 incident, Binance CEO Changpeng Zhao (CZ) began using the phrase "stay SAFU" to remind users to stay safe and secure. The phrase has since become a cultural touchstone in the crypto community.
