Binance has drawn on its futures insurance funds as part of its response to the October 29 breach that carried off approximately $6.3 billion in digital assets, according to a recovery update published by the exchange on October 31 at 14:24 UTC — two days after the incident.

The update lays out how the company plans to replace the stolen tokens, naming three funding sources, with the Secure Asset Fund for Users (SAFU) listed among them. The combination means the recovery plan spans both SAFU's exchange-wide emergency reserve and the per-market balances that normally stand behind leveraged trading on the platform.

Binance's emergency reserves

SAFU was established by Binance in July 2018 as an emergency insurance reserve funded by allocating 10% of all spot trading fees collected by the exchange. It is designed to shield user assets in extreme situations and has functioned as the company's principal backstop fund since its creation.

Futures insurance funds operate separately from SAFU. Each futures and perpetual market on the platform maintains its own insurance balance, which absorbs the shortfall that arises when a leveraged position is liquidated below its bankruptcy price, preventing those losses from being passed on to other traders in the same market.

Scale of the incident

At approximately $6.3 billion, the reported scale of the October 29 breach would exceed any previously disclosed hack in the cryptocurrency industry, including the roughly $1.5 billion stolen from Bybit in February 2025 — a sum more than four times the Bybit loss. Binance's own last major security incident occurred in October 2022, when an attacker exploited the exchange's BNB Bridge and drained about $570 million in digital assets.

The full composition of the three funding sources named in the update, and the mechanics of replacing the stolen tokens, are the details to watch as Binance's recovery plan moves forward.
