A crypto Secure Asset Fund for Users (SAFU) is an emergency fund that ensures users' holdings will be protected in the event of a hack or breach. Having a SAFU is a proactive way to enhance the security and integrity of a cryptocurrency exchange or platform.

The implementation of a SAFU boosts user confidence. Users are assured that their funds are safeguarded and they will be compensated in the event of a breach. Having a SAFU can create a more secure environment for trading and the storage of funds.

A Brief History

The concept of SAFU gained prominence following the infamous hacking of the Mt. Gox exchange in 2014. This incident showed that cryptocurrency communities needed to heighten security to protect user funds.

The Binance exchange responded by introducing the SAFU initiative in 2018. Binance allocated 10% of its trading fees to the dedicated SAFU fund. It promised to use the monies to compensate members of the Binance community in the event of a security breach. This move was widely hailed as a significant step towards improving the security and trustworthiness of cryptocurrency exchanges and platforms.

SAFU: Everything to Know

  • Purpose and Function: The primary purpose of SAFU is to protect users' funds and mitigate the financial impact of security breaches. Exchanges and platforms allocate a portion of their earnings or create reserve funds specifically designated for compensating affected users. These funds serve as an additional layer of protection. They instill confidence in users and indicate the exchange is committed to ensuring user security.
  • Funding Mechanism: Exchanges and platforms can fund SAFU reserves through various means. Some allocate a percentage of their trading fees. Others set aside a portion of their profits. Exchanges and platforms consistently contribute to reserves so they will have enough money to promptly compensate users.
  • Compensation Process: Exchanges and platforms activate their SAFU fund when there has been an incident of concern. The compensation process varies between exchanges. The first step is generally a thorough investigation to determine the extent of the breach. Part of this process involves identifying affected users. The exchange disperses monies after the investigation is complete.
  • Transparency and Accountability: Exchanges and platforms make users feel secure and informed by providing regular updates on the status of their reserve funds. They typically disclose the amount held in the SAFU fund and disbursements to compensate users. The transparency helps build confidence in the exchange or platform's commitment to user protection. It also reinforces the entity's credibility.

Getting Started

  • SAFUs are necessary because of the decentralized nature of the crypto ecosystem. A SAFU serves roughly the same purpose as the reserves of a bank or credit union.
  • An exchange or platform must share information about the SAFU and its purpose with users. Responding to user questions and concerns is a good way to encourage dialogue.
  • Users can provide input to help an exchange or platform administer a SAFU better. Users can share their experiences of being compensated. They can also offer ideas to make the disbursement process more efficient and secure.

Unique Aspects

  • SAFUs ensure security for the users of a platform or exchange. An exchange or platform that establishes a SAFU makes it clear that user funds are protected. Their work also shows that the exchange or platform's community takes security seriously.
  • This offers an exchange or platform a way to establish a reputation for reliability. Such an emphasis helps create a more robust and trustworthy cryptocurrency ecosystem.
  • SAFUs are not a guarantee against all risks associated with cryptocurrencies. Users must still exercise caution and employ best practices to safeguard their assets. Ideas include utilizing strong passwords, enabling two-factor authentication and taking steps to stop phishing attempts and other suspicious activities.


  • Investor Confidence - The existence of a SAFU fund can enhance investor confidence in a cryptocurrency exchange. Users are more likely to trust and trade on platforms that prioritize the safety of funds. The presence and proper administration of a SAFU can attract a larger user base. It can also promote healthy market activity.
  • Mitigating Losses - SAFU funds can help reimburse affected users. They mitigate financial losses, providing a safety net for individuals who have fallen victim to fraudulent activities and technical vulnerabilities.
  • Market Stability - SAFU funds contribute to the overall stability of the cryptocurrency market. They prevent panic selling and market disruptions relating to a lack of trust or overall uncertainty. Stability benefits individual users and the cryptocurrency ecosystem.
  • Regulatory Compliance - In some jurisdictions, the establishment of a SAFU fund may be a regulatory requirement for cryptocurrency exchanges and platforms. Adherence to regulations demonstrates a commitment to operating within legal frameworks.


  • Moral Hazard - The presence of a SAFU fund can create a moral hazard by potentially encouraging users to be less cautious with their security practices. Some individuals might assume that their funds are completely safe if they experience a loss. This is not always true. There may be circumstances that will not warrant a disbursement from the SAFU. An exchange or platform should inform users about conditions that may prevent a disbursement. Such effort can help reduce the risk of phishing attempts and other security breaches.
  • Centralized Control - SAFU funds are typically controlled by the cryptocurrency exchange or platform. This centralization introduces a degree of counterparty risk. The exchange or platform becomes the custodian of user funds. Users must trust that the exchange will manage the SAFU fund responsibly and transparently. There is a risk that the exchange or platform could compromise its integrity and act unfairly or secretively.
  • Limited Coverage - SAFU funds will not cover all types of losses or risks. For example, a SAFU may not cover losses resulting from user errors. Examples of such errors include sending funds to the wrong address and falling victim to social engineering attacks. Users should be aware of the specific terms and conditions of the SAFU fund. This will help them understand its limitations.
  • Cost Implications - Establishing and maintaining a SAFU fund can cost a great deal. An exchange or platform will pass the cost on to users through higher trading fees or other charges. Further, the size of the SAFU fund may impact the profitability and sustainability of the exchange or platform. This can affect the availability of services and competitiveness of trading fees.
