Threshold Network announced on the X platform that on May 18, 2026, a malicious actor attempted to mint tBTC without depositing the underlying Bitcoin. According to Odaily, the attempt was unsuccessful, no invalid tBTC was issued, and user funds were not at risk. As a precaution against frequent malicious activities in the broader crypto ecosystem, Optimistic Minting has been temporarily suspended. Currently, minting operations are conducted through a liquidation mechanism, extending the typical minting time from approximately 1.5 hours to about 6 to 7 hours.
