TL;DR:
- Zilliqa suspended native transactions after confirming a critical security flaw on July 21, 2026.
- The vulnerability affected randomness generation in the Ledger application released between 2019 and 2026.
- The ZIL token traded at $0.0024 as of July 22, 2026, recording a 17% weekly decline.
The layer-1 blockchain Zilliqa temporarily halted transfer processing on its non-EVM native network due to a Ledger incident that compromises user key privacy. The direct intervention was executed on July 21, 2026, aiming to prevent the unauthorized draining of funds stored in cold wallets.
The technical issue lies in the random number generation routine, or ephemeral nonces, used by the hardware wallet application. A lack of entropy during the cryptographic signing process allowed external observers to deduce the private key of any exposed address.
According to official data shared by the network’s developers, an attacker only needed to collect approximately five public signatures issued by the same account to reconstruct the cryptographic secret within seconds using standard hardware.
All versions of the official Zilliqa software built for these devices between 2019 and 2026 harbored the flaw in native operations. Conversely, transactions executed through Ethereum Virtual Machine (EVM) compatible environments showed no disruption in functionality.
Operational Impact and Market Response
Security monitors identified suspicious on-chain activity starting July 19, 2026. According to the project’s technical report, the preventive freeze of the native layer aims to prevent attackers from executing transfers before token holders migrate their assets to newly created addresses.
The discovery immediately impacted centralized exchange operations. Industry reports from July 22, 2026, confirm that South Korean exchange Upbit designated the ZIL token as a cautionary asset and temporarily suspended deposits and withdrawals.
The ZIL token traded at $0.0024 as of July 22, 2026. CoinMarketCap data suggests the price recorded a 1.5% drop in the 24 hours following the announcement and a 17% decline over the past seven days.
Zilliqa developers are currently collaborating with hardware manufacturer Ledger to finalize the rollout of a patched software version. According to the team’s official roadmap, the protocol will announce guided migration instructions and the reopening date for the native network on its public channels once validation testing is complete.
