Binance said Friday it will convert the stablecoin holdings in its $1 billion Secure Asset Fund for Users (SAFU) entirely into bitcoin over the next 30 days.

The exchange said the transition will be carried out gradually and accompanied by regular audits. 

Binance also pledged to replenish the fund if bitcoin price volatility causes its value to fall below $800 million, using treasury reserves to restore it to $1 billion.

Binance launched its SAFU back in 2018 to protect users against losses from extreme events such as hacks or major system failures. The fund is financed through a portion of Binance’s trading fees and is held separately from user assets in cold wallets.

Binance has repeatedly cited SAFU as a cornerstone of its risk-management and trust framework.

“This initiative is part of Binance’s long-term industry-building efforts,” the exchange said in its translated statement posted to X. “We will continue advancing related work and gradually share progress with the community.”
