Chainalysis Puts Mercado Bitcoin Hack at $49 Million Across 17 Chains

Blockchain analytics firm Chainalysis has put the value of a hack involving Mercado Bitcoin at about $49 million, according to reporting originally published by The Defiant. The estimate covers activity spanning 17 blockchain networks, underscoring the multi-chain nature of the incident.

Mercado Bitcoin is a Brazil-based crypto platform and exchange. The available reporting identifies the event as a hack but does not provide further details on the timing, attack method, affected assets, or the status of any recovery efforts.

The 17-chain figure highlights how digital-asset investigations can extend beyond a single network. Funds can move between blockchains through bridges, exchanges, and other services, making transaction tracing more complex than in an incident confined to one ledger.

Chainalysis is a blockchain analytics company whose tools are used to analyze on-chain transactions and follow the movement of crypto assets. Its $49 million assessment provides a cross-chain estimate of the Mercado Bitcoin hack’s scale rather than a detailed account of the incident.
