Mercado Bitcoin hack: wallet analysis
The hack emptied a withdrawal wallet, consumed funding arriving during the attack and left old deposit addresses receiving Bitcoin.
Binance reopened withdrawals after the hack: where Bitcoin went in the first five hours
Kraken leads the named destinations in Binance’s first five hours of reopened Bitcoin withdrawals after the hack; Coinbase’s share exceeds all eight historical comparison windows.
Binance must limit what a hacked withdrawal system can spend
On 1 November, Binance adds 2,000 BTC while its new payout wallet still holds 4,007 BTC. We trace the startup, refills and balances against the failures of the hacked wallet.
Binance should reopen with less Bitcoin exposed to its withdrawal system
Binance’s withdrawal wallet held 19,111 BTC when the hack began, 30% above its 30-day average. We will track balances, cold-storage transfers and controlled refills as payments resume.

What a Bitcoin Wallet’s Balance Leaves Out.
A balance cannot explain how a wallet is used. Follow a real exchange wallet’s transfers, major senders, and history to see what your team should check.
16 Million Operations a Second.
Our Rust state database reached nearly 16 million internal state-building operations a second in a production rebuild covering 1.429 billion source transactions. See how that engineering builds usable Bitcoin history.
AI Needs the Right Experience.
Can an AI explain a change in reserves, or recognize funds that stayed in storage? See how real Bitcoin history can become learning examples and tests your team can check.
You Can’t Justify a Transfer Without Understanding the Operation.
Understand how an institution receives deposits, funds withdrawals, and holds reserves. Then use that operational context to justify a transfer with evidence.
