What happened
A suspected bridge exploit allowed 19 million unauthorized tokens onto the Base network on October 13, 2026. The tokens were related to Autheo’s THEO token, which saw its price fall 92% in 24 hours. The exploit occurred via a bridge built on Hyperlane, moving tokens between Autheo's mainnet, Base, and Robinhood Chain, with the unauthorized mint appearing on the Base side.

Why it matters
The incident highlights that security audits performed by Halborn, CertiK, and Avelar Labs on THEO do not certify every configuration change or the full combinatorics of a message-passing system. The unauthorized minting resulted in tokens being swapped for roughly 700.8 ETH, though this figure has not been confirmed on-chain.
