The exploit that emptied Fetch.ai’s Ethereum-based token converter and produced 408.5 million unauthorized NuNet Token (NTX) on September 19, 2026, has widened right into a broader key-compromise occasion throughout the SingularityNET bridge stack, with the identical assault cluster later minting 260 million SingularityNET Token (AGIX) and 53.838 million World Cell Token (WMTx) on Ethereum on September 20, 2026.
Blockchain safety displays monitoring the cluster valued its Ethereum holdings at roughly $16.77 million on the time of their alert, whereas Fetch.ai has mentioned its personal sensible contracts stay secure and that FET continues to function usually.
SingularityNET is a decentralized synthetic intelligence (AI) market and a founding member of the Synthetic Superintelligence (ASI) Alliance, an ecosystem that additionally contains Fetch.ai, NuNet and Cogito Finance. Its native SingularityNET Token (AGIX) is a utility and funds asset; NuNet Token (NTX) settles decentralized compute funds; Cogito Finance’s governance token trades as CGV; and World Cell Token (WMTx) is the Ethereum-side utility token of World Cell Chain, a decentralized wi-fi community that has built-in the SingularityNET bridge to maneuver worth between Cardano and Ethereum. The Crypto Times reported earlier on the September 19 drain of the Fetch.ai converter contract and the linked NTX mint, which was the primary money occasion within the widening incident.
Sept 19 2026 20:21 UTC: Exploit drained 8.7 M FET from Fetch.ai converter, marking the incident’s first money loss.
Sept 19 20:50 UTC: Similar attacker minted 408.5 M NTX, then on Sept 20 minted 260 M AGIX and 53.8 M WMTx.
Sept 20 all through day: Fetch.ai, World Cell paused bridges, issued alerts; safety corporations valued stolen property at $16.77 M.
Blockchain safety agency PeckShield reported at 09:21 UTC on September 20, 2026, that the exploiter had minted 260 million AGIX and 53.838 million WMTx on Ethereum. On the time of the alert, PeckShield valued the cluster’s holdings at about $16.77 million, comprising 198.3 million AGIX price roughly $14.42 million, 649 ETH price roughly $1.67 million, and 33.538 million WMTx price roughly $627,350. The safety agency had beforehand valued the FET drain at about $1.53 million and the NTX mint at about $462,730.
Individually, blockchain information supplier Bitquery reported at 17:20 UTC on September 20, 2026, that roughly 2.3 billion newly created models throughout AGIX, NTX, CGV and WMTx have been traced to the identical actor, along with the 8.7 million FET drained from the Fetch.ai converter.
Bitquery famous that a big share of the remaining AGIX provide on Ethereum, Cardano and BNB Chain now seems to be unauthorized stock. The Bitquery depend spans extra tickers and chains and must be learn alongside, not rather than, PeckShield’s Ethereum-only AGIX and WMTx snapshot.
What Fetch.ai and World Cell Have Confirmed
Fetch.ai posted at 16:19 UTC on September 20, 2026, that Fetch.ai contracts weren’t beneath menace and that FET continues to function usually. The crew mentioned the assault focused SingularityNET contracts, “primarily the SingularityNET Bridge between Ethereum and Cardano,” and that the unauthorized mints used that route.
AGIX-to-FET conversions have been paused, and the Ethereum-side Fetch.ai bridge was paused as a precaution, with the crew stating there was no indication of any vulnerability in it. Fetch.ai mentioned the exploit had been contained and that it was persevering with to work with SingularityNET.
An earlier Fetch.ai update at 08:51 UTC pointed to a preliminary on-chain analysis hosted on ASI:One which traced the trail from a compromised signing key to cash-out wallets. The crew mentioned it had deactivated affected wallets and a contract along with SingularityNET, and cautioned that the write-up was preliminary and never a closing evaluation. Fetch.ai first acknowledged converter-related studies at 06:51 UTC on September 20 and paused its Ethereum-side bridge at 12:51 UTC on the identical day.
World Cell Chain confirmed at 05:07 UTC on September 20, 2026 that the SingularityNET bridge had been exploited and that WMTx had been minted on Ethereum with out authorization, driving value motion on listed venues. The crew mentioned it was contacting exchanges to freeze affected deposits and dealing with safety companions to revoke minting authorities.
A follow-up message at 06:31 UTC mentioned a pre-exploit snapshot was underway and instructed holders to not work together with WMTx whereas the investigation continued. Each posts warned in opposition to restoration direct messages, pretend help accounts, and unofficial migration hyperlinks.
On the time of this report, SingularityNET had not printed a standalone incident assertion on X similar to these issued by Fetch.ai and World Cell Chain.
On-Chain Timeline Already on File
The FET drain stays the primary confirmed money occasion of the incident and occurred at 20:21:47 UTC on September 19, 2026, in Ethereum block 26,013,913. The transaction known as the conversionIn operate on the TokenConversionManagerV3 contract at 0xab424A430CC09864fA1277A38193111705ADF3A3 and moved 8,721,530.40 FET to the recipient pockets 0x2dcc1085fDCf418B421E45e86e4e54637cc21dfE. The initiating handle was 0x1572F2af7696b39c85E3221CDE8EFb640F86c362.
Twenty-eight minutes later, at 20:50:11 UTC, the NuNet deployer account 0x863F13e5B505f1Eb17803b94EC9d3DaF80092165 executed a mint of 408.53 million NTX on the NTX token contract at 0xF0d33BeDa4d734C72684b5f9abBEbf715D0a7935 and despatched the newly created provide to the identical cluster pockets.
Fetch.ai’s later evaluation described a stolen SingularityNET bridge authorizer key used to supply a sound signature for the converter name, alongside a individually compromised NuNet mint key used throughout the identical window. The unauthorized AGIX and WMTx Ethereum mints adopted from that cluster and underlie PeckShield’s $16.77 million holdings determine.
Trade Motion and Market Affect
Cryptocurrency trade Bitget suspended FET deposits and withdrawals beginning at 06:00 UTC+8 on September 20, 2026, citing pockets upkeep, with no resumption time specified. Cryptocurrency trade KuCoin was individually reported to have halted FET deposits over the identical window. FET traded close to $0.18 on the time of the drain on September 19 and was quoted round $0.172 on September 20, down roughly 5% over 24 hours.
Newly minted provide drove NTX and WMTx sharply decrease as soon as it reached the market. NTX fell between 65% and greater than 90% relying on the tracker used, whereas WMTx was reported down about 43% in early protection of the SingularityNET-side leg of the incident.
What Stays Unclear
The general public file nonetheless lacks a standalone root-cause put up from SingularityNET, a full transaction record for the AGIX, WMTx and CGV mints, and a reconciled circulating-supply desk throughout Ethereum, Cardano and BNB Chain. PeckShield’s 260 million AGIX and 53.838 million WMTx figures describe unauthorized Ethereum minting linked to the cluster relatively than tokens already offered, and Bitquery’s 2.3 billion-unit estimate spans extra tickers and chains.
Till these two datasets are reconciled in opposition to official contract states, headline dollar-loss figures must be learn because the sum of minted stock plus FET drained, and never as realized proceeds.
Investigations proceed. Customers have been suggested to disregard unsolicited restoration messages and to rely solely on the official Fetch.ai, World Cell, and SingularityNET channels for updates.
