Summary

Autheo Networks is a Layer-0/Layer-1 blockchain project founded in 2024 whose native THEO token launched on Hydrex in August 2026. On October 12, 2026, an attacker exploited a single trusted-relayer key in the project's Hyperlane bridge on Base to mint 19 million unbacked THEO tokens, swapping approximately 9.5 million of them for roughly 700.8 ETH (~$1.76 million) across approximately 54 transactions before bridging the proceeds to Ethereum mainnet. The resulting sell pressure caused THEO to lose approximately 92% of its value within 24 hours. As of publication, Autheo has not released a technical postmortem, confirmed root cause, or announced a recovery or compensation plan.
