6.7 million $XLM linked to Mercado Bitcoin's $48.5 million security breach. 🔐 Brazilian crypto exchange Mercado Bitcoin confirmed a security incident on November 2, with blockchain investigators tracking suspicious transfers across 10 networks. According to Bitquery's onchain investigation: ⭐️ 6.71M XLM traced to a Stellar address linked to the incident. 💵 979,527 USDC also identified at the same Stellar address. 🌐 $48.5M in total outflows across 10 blockchains, including Bitcoin, Ethereum, Stellar, and Solana. 🔎 Exchange wallet compromise: Investigators identified unauthorized transfers involving hot wallets and customer deposit addresses. 🛡 Asset recovery: Tether and Paxos have frozen approximately $7.3M in assets linked to the incident, according to Bitquery. Mercado Bitcoin says customers will not suffer financial losses and that personal data was not compromised. An important distinction: this was not a breach of the Stellar network itself. The incident highlights a critical challenge for digital asset infrastructure: securing private keys, transaction signing systems, and institutional custody across multiple blockchains. Blockchain security matters. But the infrastructure controlling access to digital assets matters just as much. 🔐🌍
