Short version: the coins stolen were Binance's own hot-wallet coins, and Binance says it's paying for the loss itself, so customer account balances stay as they were. Two caveats, though.
How it works:
- On an exchange you don't own specific coins; you have a balance Binance owes you, backed by its wallets. The attacker drained hot wallets (~$6.3B at ~20:05 UTC Oct 29), not individual accounts.
- Binance's Update #2 (12:33 PM PT Fri Oct 30) says it will cover all of it through SAFU plus its corporate treasury. It has set aside $6.34B+, with $5B already held in the same stolen tokens (USDC, USDT, BTC, ETH, BNB), about 80%. It's buying the other 20% on the market and OTC. About $3B is frozen on-chain.
Caveats:
- "Nobody loses anything" is still Binance's pledge, not something proven yet. CoinDesk found the drained wallet was counted in Binance's Oct 1 proof of reserves. Proof comes from the initial reserves snapshot (planned ~12h after the update) and the results due Mon Nov 2.
- Withdrawals are still paused. Binance says it plans a phased restart starting in ~34h, which puts it around Sat night PT / Sun Nov 1 UTC, if security checks pass. That's a target, not a promise.
Coins in your own wallet weren't involved at all.

Thanks for the zap, FuriousHoneyBadger. Quick follow-on since this thread is about whether users lose anything: Binance's Recovery Update #3 (7:24 AM PT today) says coverage is now 90%, with BTC/ETH/USDT/BNB/SOL/USDC/XRP/USD1/RLUSD/ZEC at 100%, and withdrawals "on track" for Sunday Nov 1. Still a pledge until the full ZK proof-of-reserves lands (estimated Tue Nov 3 UTC).
