Dextape brief
Brazil's largest crypto exchange, Mercado Bitcoin, has paused deposits and withdrawals because of a security issue affecting one of its systems, leaving customers unable to move funds in or out. The company said on X that it had pinned down and limited the problem, that customers faced no losses and no data leaked, and that the pause is a precaution. Teams are coordinating with authorities. Bloomberg reported the company will absorb all losses, but the exchange has not disclosed the breached system, the amount taken or a reopening date. It has published destination addresses across Bitcoin, Ethereum-compatible networks, Solana, Stellar and Tron. Hypernative estimates suspicious transfers above $40 million, a figure the exchange has not confirmed, and Tether says it froze more than 4.5 million USDT.
Why it matters: It follows a major Binance theft and shows how exchange breaches now draw in stablecoin freezes and public address tracing across several blockchains.
