Binance’s Secure Asset Fund for Users (SAFU) holds about 7,500 BTC, and Bitcoin’s slide below $70,000 on November 13 has pushed the fund’s implied market value to roughly $516 million. That sits approximately $284 million below the $800 million threshold that Binance’s SAFU policy sets as the trigger for a top-up to $1 billion.
Although Binance has confirmed that it covered all affected customer assets, it has not confirmed whether SAFU replenishment has begun.
What the SAFU Wallet Shows On-Chain
On-chain records from the SAFU wallet on mempool.space show the SAFU address, 1BAuq7Vho2CEkVkUxbfU26LhwQjbCmWQkD, held just above 7,500 BTC as of early November after two outgoing transactions on October 31 cut the balance in half, CoinDesk reported.
The wallet previously held approximately 15,000 BTC in February, when Binance completed converting the roughly $1 billion fund from stablecoins into Bitcoin.
When those early-November readings were taken, Bitcoin traded near $77,000, valuing the remaining SAFU balance at about $580 million. Bitcoin has since fallen to approximately $68,800, dropping the fund’s implied value to roughly $516 million.
That figure is FinanceFeeds’ own calculation based on the last confirmed wallet balance and the current spot price. Binance has not published an updated SAFU valuation since the hack.
Binance’s $800 Million Refill Rule in Its Own Words
The SAFU frequently asked questions page states one clear trigger for replenishment. “If the fund’s market value falls below US $800 million due to BTC price fluctuations, Binance will rebalance the fund to restore its value to $1 billion,” the policy reads.
At roughly $516 million, the current shortfall against that threshold is approximately $284 million. Reaching the $1 billion target from the present level would require adding about $484 million in Bitcoin, or roughly 7,035 BTC at today’s price.
The clause specifies “BTC price fluctuations” as the condition, not deployment spending. Multiple outlets have noted that the policy’s wording does not clearly state whether the same obligation applies when the fund is spent on hack-related payouts, news.bitcoin.com reported.
What the Hack Cost and How It Was Covered
Binance disclosed on October 29 that attackers exploited a tainted developer install to steal assets across multiple blockchains, according to the exchange’s incident disclosures. Binance put the loss at approximately $6.3 billion.
TRM Labs estimated the figure at $6.36 billion and Elliptic at $6.43 billion, according to reports from CNBC and CoinDesk. On October 31, Binance confirmed it would use a combination of the SAFU fund, its corporate treasury, and a portion of its futures insurance fund to cover affected users.
The exchange set aside $6.34 billion to cover affected customer assets and deployed 7,499 BTC from the SAFU wallet in two transfers six minutes apart. Recovery Update #5, released on November 2, showed that the coverage ratio for affected tokens had reached approximately 95%, with the remaining 5% consisting of lower-liquidity tokens outside the top ten.
Binance subsequently reported that coverage had reached approximately 98% by November 4 before announcing on November 12 that all $6.34 billion in affected customer assets had been covered.
Binance Pledges $1 Billion Refill But Sets No Timeline
Binance posted in an October 31 FAQ on X that it is “committing to replenishing the SAFU to return the fund size to approximately US$1 billion.” The exchange provided no deadline for the restoration.
On November 12, Binance announced that it had covered all $6.34 billion in affected customer assets using its corporate treasury, SAFU, and futures insurance fund surplus. This announcement confirmed customer asset coverage, not the completion of the separate SAFU replenishment, which remains pending.
The SAFU address remains publicly viewable on blockchain explorers, meaning any large inflow of Bitcoin to the wallet would be visible within minutes, making the refill one of the more transparent data points in crypto exchange operations.
What This Means For Users
SAFU exists to cover user losses in extreme events, and the 7,499 BTC withdrawal on October 31 removed approximately half of the fund’s Bitcoin holdings. The gap between the wallet’s value and the $800 million refill line has widened from roughly $220 million in early November, when Bitcoin traded near $77,000, to approximately $284 million at today’s price.
For users, the practical question is whether Binance can absorb a second major incident before the fund is restored. The exchange has not disclosed how much of its futures insurance fund was used alongside SAFU or the level of reserves that remain beyond the on-chain wallet.
