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.

Nesa mainnet reported to have launched, with 1 billion NES tokens created at genesis.
WebSearch aggregation of secondary crypto-wiki sourcesApril 2026
A security researcher reported the Cosmos EVM integer-underflow vulnerability to Cosmos Labs; Cosmos Labs' testers were unable to reproduce the exploit against live-chain configurations and wrongly concluded funds were not at risk.
The BlockAugust 2026
Attackers exploit the Cosmos EVM vulnerability against KiiChain and TAC, draining roughly 148 million KII and roughly 3 billion TAC tokens (valued around $7.5 million) respectively.
ProtosAugust 2026
Attacker exploits the Cosmos EVM underflow bug on Nesa, withdrawing 257,703,733 NES (~$50M, ~25.8% of stated supply) via Hyperlane to Ethereum; Nesa halts its chain and Binance Wallet later offers a 1:1 contract swap for pre-halt holdings.
rekt.news / ProtosAugust 2026
Cosmos Labs issues a public warning urging Cosmos EVM chains to halt and apply the security patch, roughly 20 hours after the patch's release.
ProtosAugust 2026
Cosmos Labs publicly acknowledges it wrongly cleared the underlying bug after an earlier report, and discloses the incident's total impact across six chains at approximately $5.7 million net.
