anchored·4stqts…ASWWSummary
SingularityNET is a blockchain-based AI services marketplace whose legacy AGIX token and associated cross-chain bridge (linking Ethereum and Cardano) were targeted in a coordinated key-compromise attack between September 19 and 21, 2026. An attacker who had obtained the bridge's offline conversion-authorizer signing key — and separately a dormant 2023 AGIX minter key — used valid cryptographic signatures to mint 260 million AGIX and 53.8 million WMTx on Ethereum, with total attacker-controlled value reaching approximately $16.77 million; AGIX collapsed more than 99% in 24 hours, wiping an estimated $93 million in market capitalization. The incident was part of a broader multi-protocol attack that also drained 8.72 million FET from Fetch.ai's TokenConversionManagerV3 and minted 408.5 million NTX on NuNet, all attributed by on-chain security firm PeckShield to the same threat actor.

Timeline(10 events)
19 September 2026
First exploit transaction recorded at 20:21 UTC: attacker calls conversionIn on Fetch.ai's TokenConversionManagerV3, draining 8,721,530 FET (~$1.55M) to an attacker-controlled wallet.
Crypto Times / Metaverse Post19 September 2026
Approximately 29 minutes after the FET drain (approximately 20:50 UTC), the attacker mints 408.5 million NTX tokens, representing approximately 42% of NuNet's total supply.
Metaverse Post / Crypto Times20 September 2026
Attacker mints 260 million AGIX tokens on Ethereum using a compromised bridge authorizer key and a separately compromised dormant 2023 AGIX minter key.
PeckShield via PANews / KuCoin20 September 2026
Attacker mints 53.838 million WMTx tokens on Ethereum through the same compromised bridge infrastructure.
PeckShield via PANews / Crypto Times20 September 2026
Fetch.ai issues first public acknowledgment of converter reports at 06:51 UTC — more than 10 hours after the initial exploit transaction.
Crypto Times20 September 2026
PeckShield publicly attributes all minting activity to a single attacker cluster and reports total holdings of approximately $16.77M at 09:21 UTC.
PANews / KuCoin20 September 2026
Fetch.ai pauses its Ethereum-side bridge contract at approximately 12:51 UTC as a precautionary measure; AGIX-to-FET conversions suspended. Bitget suspends FET deposits and withdrawals; KuCoin halts FET deposits.
Crypto Times / Crypto Economy20 September 2026
AGIX token price collapses from approximately $0.0775 to $0.0006841 — a decline of more than 99% — within 24 hours, wiping an estimated $93 million in market capitalization.
Blockzeit / Coinotag20 September 2026
Fetch.ai confirms its core contracts were not affected; SingularityNET states treasury and exchange wallets are not impacted and that holders need take no action. No comprehensive incident report published.
Coinfomania / Blockonomi21 September 2026
Bitquery on-chain monitoring reports that the compromised conversion authorizer key has not been rotated and the stolen NuNet minter role has not been revoked — more than 48 hours after the initial exploit. Attacker's realized profit reaches approximately $2.25M through token sales.
