Zilliqa Suspends Native Transactions After Ledger Signature Flaw Disclosure

Zilliqa suspended native transactions after disclosing that roughly five affected Ledger app signatures from the same private key may allow attackers to reconstruct that key. According to NS3.AI, the flaw affects native, non-EVM transactions signed through Zilliqa Ledger app versions released between 2019 and 2026. Zilliqa detected on-chain activity consistent with active exploitation on July 19 and did not quantify any losses. The network has not announced a reopening date or a final migration procedure.
