Key points

- Hypernative put suspicious transfers at more than $40m across at least 10 blockchains, Arkham traced at least $46m and Chainalysis about $49m.
- Deposits and withdrawals were frozen on 2 November and remain suspended, with no date given for resuming service.
Mercado Bitcoin says customers will not carry the cost of the hack that hit its systems on 2 November.
Estimates of the loss vary. Mercado Bitcoin puts the value of the assets involved at about $38m and says it has blocked $11m after working with Tether, Circle, Paxos, BRL1 and Chainalysis.
Tether chief executive Paolo Ardoino said on X that more than $4.5m in USDT tied to the incident had been frozen. Deposits and withdrawals were suspended as a precaution on 2 November and have not restarted.
The breach came days after hackers drained more than $6bn from Binance on 29 October, an attack the FBI blamed on North Korea's TraderTraitor group. Binance chief executive Richard Teng said his exchange would absorb the impact on users and that about 95% of affected assets had been replenished.
What to watch: Mercado Bitcoin says it will post updates on X and resume deposits and withdrawals once full security is restored, without giving a date.
