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.
On September 20, 2026, attackers exploited smart contracts for Fetch.ai and NuNet after compromising private keys used by both projects. The attacker drained approximately 8.7 million ethereum tokens worth $2M and illegally minted over 408 million NTX tokens by leveraging missing security controls in the conversion contracts.
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.
SlowMist reported a ~$2M loss from Fetch.ai due to a compromised private key used to authorize a TokenConversionManagerV3 contract. The attacker exploited missing security checks in the conversionIn() function to drain the bridge's entire FET balance in a single transaction.
