The Secure Asset Fund for Users (SAFU) is an emergency insurance fund established by [[Binance]], one of the world's largest cryptocurrency exchanges. It's designed to protect a portion of user funds in extreme cases, such as security breaches or hacks. Binance allocates a percentage of their trading fees to this fund, which is held in secure cold wallets. Think of it as a safety net for users in case the exchange's security measures fail. SAFU has become a symbol of trust and security in the often volatile world of cryptocurrency.
