On September 19–20, 2026, the SingularityNET Ethereum–Cardano bridge was compromised when an attacker with admin signing keys minted millions of unbacked tokens (FET, AGIX, WMTX, NTX, CGV) without burning collateral, draining approximately 8.7 million FET and creating billions in unsupported supply across tokens. The bridge was subsequently shut down as a precaution, though closing the website did not revoke the compromised keys that enabled the unauthorized minting.
On September 19–20, 2026, the SingularityNET Ethereum–Cardano bridge was compromised when an attacker with admin/signing keys minted hundreds of millions of unbacked tokens (AGIX, FET, NTX, WMTX, CGV) without corresponding burns, draining ~8.7 million FET and causing significant token dilution and price crashes. World Mobile and other affected projects halted trading, initiated containment and snapshot reconciliation, while exchanges froze deposits and the community debated responsibility and recovery efforts.
The global crypto market rose 2.3% to $2.87 trillion, with Bitcoin at $81,361 and Ethereum at $2,662. The Artificial Superintelligence Alliance (FET) experienced a security exploit on its Ethereum token converter where attackers drained approximately $1.56 million in FET using compromised signing keys, prompting industry warnings about AI agents enabling large-scale hacking attacks.
A SingularityNET exploit initially involving 8.72 million FET tokens expanded significantly when researchers discovered the same attacker group was linked to 260 million AGIX and 53.8 million WMTx illegally minted tokens, totaling approximately 2.3 billion across multiple tokens valued at $16.77 million in Ethereum assets. The vulnerability affected SingularityNET and an Ethereum-Cardano bridge rather than direct smart contract attacks.
The Artificial Superintelligence Alliance's FET token experienced a sharp decline following a security exploit in its Ethereum token converter, where approximately 8.7 million FET tokens were drained and a larger amount of NTX tokens were minted. The incident underscores how a single smart contract vulnerability can undermine months of development work.
The Artificial Superintelligence Alliance discovered an exploit in the FET token migration bridge that resulted in an unauthorized withdrawal of approximately $1.56M in FET tokens. The team is investigating with security partners, but treasury and exchange wallets remain unaffected, and users holding FET elsewhere do not need to take action.
