Binance's SAFU fund is down to ~7,500 BTC after the exchange tapped it for a $6.3B hack

Binance has spent roughly half the bitcoin in its Secure Asset Fund for Users (SAFU), the emergency reserve it holds to backstop customers, drawing it down to cover losses from a $6.3 billion hack. As of Tuesday the fund held just above 7,500 BTC — about $580 million at roughly $77,000 a coin — down from 15,000 BTC earlier this year, according to on-chain data cited by CoinDesk.

The wallet Binance publicly identifies as its SAFU address (1BAuq7Vho2CEkVkUxbfU26LhwQjbCmWQkD) was reduced by half across four transactions on Oct. 31, per mempool.space data reviewed by CoinDesk. Binance had finished converting the roughly $1 billion fund from stablecoins into 15,000 BTC in February.

Binance said on Oct. 31 that it would make a partial SAFU deployment as one piece of the $6.34 billion it set aside to cover the breach, drawing also on its corporate treasury and part of its futures insurance fund. It pledged to restore SAFU to about $1 billion but gave no timeline, and hasn't disclosed how much of the insurance fund it used. The exchange has separately said it replaced 90% of the stolen crypto. CoinDesk says it has asked Binance for comment.

Key facts

• SAFU wallet held just above 7,500 BTC as of Tuesday, down from 15,000 BTC in February — a ~50% cut (mempool.space, via CoinDesk).
• Remaining bitcoin worth about $580 million at ~$77,000/BTC (CoinDesk).
• Four withdrawal transactions executed Oct. 31 (mempool.space, via CoinDesk).
• Total set aside for the hack: $6.34 billion, combining SAFU, corporate treasury and futures insurance funds (Binance, via CoinDesk).
• Binance pledged to rebuild SAFU to ~$1 billion — no timeline given (Binance, via CoinDesk).

The real-world read

The headline figure to watch is Binance's own rule. Its SAFU FAQ says the fund is rebalanced back to $1 billion if its value drops below $800 million "due to BTC price fluctuations." The fund is now around $580 million — well under that line — but the trigger is written to cover price declines, not the exchange spending the money. So Binance's own published backstop doesn't, by its terms, compel the refill it has verbally promised. The $800 million floor and the "about $1 billion" restoration pledge are commitments, not contractual triggers here.

Two things are conspicuously unstated: when SAFU gets refilled, and how much of the futures insurance fund was drained. The "replaced 90% of stolen crypto" line is Binance's own claim and hasn't been independently verified. Note this account rests on a single secondary report and the on-chain data it cites; Binance had not commented at publication.
