MAP Protocol has shut down its bridge connecting MAPO ERC-20 tokens and the MAPO mainnet after a reported exploit targeting Butter Bridge V3.1. The pause, a standard containment measure in crypto security incidents, is designed to prevent further damage while the team investigates the scope of the breach.
Cross-chain bridges remain one of the most attacked pieces of infrastructure in all of crypto. And this latest incident is a reminder that the plumbing connecting different blockchains is still, to put it charitably, a work in progress.
What happened
MAP Protocol, which operates a peer-to-peer cross-chain infrastructure layer, confirmed that it paused bridge operations between its ERC-20 token (the Ethereum-based version of MAPO) and its native mainnet token. The exploit was linked to Butter Bridge V3.1, a component of the protocol’s cross-chain transfer system.
The specifics of how the exploit was carried out have not been disclosed. The extent of financial losses, if any, is also unclear at this point. Whether user funds were directly compromised remains an open question.
