Hack of Brazil's Largest Crypto Exchange Mercado Bitcoin: Incident Details

Brazil's largest cryptocurrency exchange, Mercado Bitcoin, has faced a security incident. The platform temporarily suspended deposit and withdrawal operations after detecting suspicious transactions.

Hypernative experts identified asset transfers totaling over $40 million from wallets linked to the exchange.

The attackers moved funds to new addresses across various blockchain networks, including Bitcoin, Ethereum, Solana, Tron, Polygon, Arbitrum, Avalanche, BNB Smart Chain, and Stellar.

Among the stolen assets were:

• 106 BTC
• 2,852 ETH
• 10,700 SOL
• 7M TRX
• Over 200 other tokens

Mercado Bitcoin representatives stated that client funds were not compromised. No personal data leak was recorded either. The company is conducting an investigation in cooperation with competent authorities.

The exchange has not yet officially confirmed the potential loss of over $40 million. However, the company continues to monitor asset movements.

Emoji — only if they carry meaning.

Tether has frozen $4.5 million in USDT related to the Mercado Bitcoin exchange hack, according to the company's founder, Paolo Ardoino.
