anchored·4Kuy81…8oqJSummary
Nesa is a Cosmos-based Layer-1 blockchain marketed as infrastructure for verifiable, privacy-preserving AI, with its NES token launched via Binance Alpha in mid-2026. On August 24, 2026, an attacker exploited an integer-underflow vulnerability in the shared Cosmos EVM module to inflate a NES balance roughly 200x and bridge approximately $50 million worth of tokens (25.8% of stated supply) out via Hyperlane to Ethereum, crashing the NES price as much as 90% before a partial recovery; extreme slippage limited the attacker's realized profit to roughly $60,000. The same vendor-level bug hit MANTRA, TAC, and KiiChain in the same window, and Cosmos Labs has since admitted it wrongly cleared the underlying flaw months earlier; Nesa's own post-incident transparency has drawn separate criticism for withholding technical detail that peer chains disclosed.
