Binance's SAFU fund, the emergency reserve it set up to protect users, now holds just over 7,500 bitcoin, about half of what it held in February. Binance said on October 31 that it used part of the fund, along with company money, to cover the roughly $6.3 billion hack. It has promised to refill SAFU to about $1 billion but hasn't said when.

Key facts

  • Who: Binance and its Secure Asset Fund for Users (SAFU), an emergency reserve it holds in bitcoin
  • What: A transfer of 7,499 bitcoin out of the SAFU wallet on October 31, used toward covering the hack
  • How much: Just over 7,500 bitcoin left, about $580 million at November 3 prices, per CoinDesk
  • When: Hack on October 29, 2026; the SAFU transfer on October 31
  • Source: CoinDesk, from public blockchain data and Binance's statement

Half of Binance's emergency fund is gone. The wallet that holds the Binance SAFU fund sent out 7,499 bitcoin on October 31 and now holds just over 7,500, about half the roughly 15,000 it held after Binance moved the fund into bitcoin in February, CoinDesk reported. At November 3 prices, what's left is worth about $580 million.

Binance said on October 31 that a "partial deployment" of SAFU was one of the ways it covered losses from the roughly $6.3 billion hack of October 29. Its futures insurance fund and its own company money covered the rest, Cointelegraph reported. Binance didn't say how much came from each.

What SAFU is

SAFU stands for Secure Asset Fund for Users. Binance created it in 2018 as a reserve to pay users back after a hack or similar loss. It is Binance's own money, set aside by Binance. It isn't insurance from an outside company or a government guarantee, like the deposit insurance on a bank account.

The refill rule has a gap

Binance's rules say it will top the fund back up to $1 billion if its value falls below $800 million because the bitcoin price drops. The fund is now well below that line. But the rule covers price moves, not money spent on a hack, CoinDesk noted.

Binance said on October 31 that it is "committing to replenishing the SAFU to return the fund size to approximately US$1 billion." It gave no date. Since then, the 7,500 bitcoin that left the fund moved again in a single transfer to an unlabeled address, Unchained reported. Binance hasn't explained that move.

What it means if you use Binance

  • Losses were covered with company money. Binance says it has replaced about 95% of what was stolen, as we reported in our story on the FBI's findings.
  • The cushion for the next problem is smaller. Until SAFU is refilled, the fund that backs Binance's promise to users is about half its usual size.
  • No one will contact you to "move funds to SAFU." Messages like that are scams. Check news only inside the app, and read how fake support pitches work.

Two questions are still open: when Binance will refill the fund, and whether it will change the rule so spending on a hack counts too. We'll update this story when it says.
