A bridge infrastructure connected to SingularityNET was exploited, leading to unauthorized minting of approximately 53.8M tokens on Ethereum and causing WMTX to drop ~50%. The post clarifies that Cardano itself was not hacked, emphasizing the distinction between bridge risk and blockchain risk.
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.
Two DeFi protocols experienced security exploits in September 2026. World Mobile Token (WMTX) dropped 50% after a SingularityNET bridge exploit minted 53.8M unauthorized tokens on Ethereum, though Cardano itself was unaffected. CICADA Finance completed recovery following an rtUSQ exploit, migrating assets from pre-incident snapshots and deploying new contracts with restored liquidity and protocol functions.
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 security exploit affecting SingularityNET's bridge between Ethereum and Cardano has grown significantly larger than initially reported. Attackers exploited vulnerabilities in SingularityNET's smart contracts and the Ethereum–Cardano bridge to illegally mint approximately 2.3 billion tokens (AGIX, NTX, CGV, WMTx) worth an estimated $16.77 million in Ethereum assets.
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.
X posts discuss Ethereum and cryptocurrency market developments, including IMF recognition of XRP Ledger and XLM adoption by financial institutions, a security exploit affecting SingularityNET bridge contracts between Ethereum and Cardano, and trader speculation about potential breakouts in BTC and ETH prices.
A X discussion thread covers multiple cryptocurrency security incidents: Harmony's Layer-1 chain shutdown due to past exploits, with ONE tokens migrating to Ethereum; and a SingularityNET bridge exploit causing unauthorized WMTx minting. A third post discusses an ICLR26 paper on preference learning that uses natural-language rationales to improve reward model robustness.
Fetch.ai reported that an exploit on September 19 targeted SingularityNET Bridge contracts between Ethereum and Cardano, resulting in unauthorized minting. Fetch.ai's own contracts remain unaffected, though AGIX to FET conversions and the Ethereum bridge contract have been paused as a precaution while the investigation continues.
