UPDATE · Oct 30, 6:45 AM ET: Binance now puts the total impact at about $6.3B, the largest crypto theft on record, with about $3B frozen. Withdrawals are targeted to reopen late Saturday or early Sunday ET. See our market sentiment follow-up. Original report below.
Late Thursday afternoon, billions of dollars in crypto left Binance's hot wallets for an address that didn't exist that morning. Binance has paused withdrawals on multiple networks and says user funds are safe. Its founder says it looks like a hack. Here's what we know, what we don't, and where Solana fits.
What happened
At 4:24 PM ET (20:24 UTC), a single transaction moved about 167,464 ETH, roughly $1.6 billion in USDT and more than 60 other tokens out of the Binance hot wallet labeled "Binance 14" to a newly created address. A second Binance wallet sent another 28,005 ETH to the same address 24 seconds later, according to Etherscan data reported by BeInCrypto.
About 17 minutes later, the same initiating address pulled roughly 780 million USDC from another Binance hot wallet to the same destination, Odaily reported. Most trackers put the total at about $3.3 billion to $3.5 billion. Arkham's widely shared $5.8 billion figure counts everything held across the tracked wallets, not a confirmed loss.
Two details point to theft rather than routine wallet maintenance:
- The wallet that triggered the transfers was funded only through Tornado Cash, a coin mixer, with three small deposits on October 28 and 29.
- The funds moved on quickly. Within about 15 minutes, the receiving address forwarded about 195,460 ETH to yet another fresh address.
What Binance and others have said
Binance said on X that it is "actively investigating" reports of a potential security issue and that "user funds are completely safe." It edited that post twice in 13 minutes; the first version said it had "not confirmed any impact to user funds." A spokesperson told TechCrunch Binance has "temporarily suspended withdrawals on multiple networks following a security incident as a precautionary measure," and said withdrawals will resume once the issue is fully resolved.
Binance still hasn't called it a hack, given a loss figure or a cause, or said whether it will tap SAFU, its emergency fund, which now holds 15,000 BTC (about $1.2 billion).
Founder Changpeng Zhao went further: "It does look like a hack on Binance," he wrote, adding that "user funds are safe" and that he expects all user funds "will be fully covered." Asked about an estimate that the loss after freezes was about $1 billion, he replied: "Loss might be a bit higher than that, but will cover."
The stablecoin issuers moved fast. Tether CEO Paolo Ardoino said Tether froze more than 1.567 billion USDT. Circle CEO Jeremy Allaire said Circle froze more than 800 million USDC "in coordination with law enforcement," the first sign that authorities are involved. That's about $2.4 billion frozen. The rest, more than $1 billion and mostly ETH, can't be frozen; about 700 million USDT also left the receiving address before the blacklist, and much of it was swapped into ETH.
Was Solana involved?
Not so far. Every reported transfer is on Ethereum: ETH, ERC-20 stablecoins and other Ethereum tokens. We found no reports of SOL, Solana-based tokens or Binance's Solana wallets being drained, and no sign yet of stolen funds being bridged or swapped through Solana. Binance hasn't said which networks are covered by its withdrawal pause, so Binance users should assume SOL withdrawals may be affected until it says otherwise.
Market reaction
The news hit an already shaky market. BNB took the hardest hit, falling about 6% in the first hour. CoinDesk reported Bitcoin falling about 2% in an hour to around $78,800, and roughly $590 million in long positions were liquidated in about an hour, according to Crypto Briefing.
SOL slipped below $100 and touched intraday lows near $95. As of 7:50 PM ET, CoinGecko shows:
- SOL: $96.09, down 6.1% over 24 hours
- BTC: $78,227, down 3.7%
- ETH: $2,256, down 4.3%
- BNB: $701, down 7.5%
What it means for SOL
Short term, contagion trades on fear, not chains. SOL fell with everything else because Binance is one of the largest venues for SOL spot and perpetuals. With withdrawals paused there, arbitrage between Binance and other venues gets harder and SOL liquidity takes a hit regardless of which chain was attacked.
Stablecoin freezes cut both ways. Tether and Circle freezing about $2.4 billion within hours shows that issuer controls can cap a hack's damage. The same USDC and USDT controls apply to the roughly $15 billion of dollar stablecoins on Solana. That's a safety feature for institutions and a reminder that these assets are centrally controlled.
Exchange risk is the lesson, not chain risk. This looks like a key or operational compromise at a centralized exchange, not a protocol flaw. A hack this size could push more users toward self-custody and on-chain venues. On Solana, that means DEXs, Jupiter and wallets like Phantom, which already handle a large share of on-chain trading.
The SOLTRACER take
This is a developing story, and the most important facts are still missing: whether Binance confirms a breach, how much was actually lost, how it happened, and when withdrawals reopen. For SOL, the near-term risk is market liquidity and sentiment, not anything wrong with Solana itself. Watch Binance's next statement, whether SAFU is used, the attacker's ETH as it moves, and whether SOL can hold the $95 area once the liquidations clear. We'll update this post as Binance responds. SOL price and stablecoin data are on the Dashboard.
