Oraichain EVM cross-chain transfer path

Oraichain-operated EVM cross-chain transfer path affected by an August 2026 unauthorized ORAI minting incident. Oraichain later restored the network and completed on-chain restoration, but the reviewed first-party material does not separately prove full post-incident restoration of the affected cross-chain path.

Incident cases

  • Oraichain August 2026 unauthorized cross-chain ORAI mintApprox. 2026-08-08

    During August 8–9, 2026, Oraichain detected abnormal mainnet activity and identified a vulnerability in an EVM cross-chain transfer path that enabled unauthorized ORAI minting. The network was halted from 04:00 UTC on August 9 and bridges, cross-chain routes and public interfaces were restricted. Oraichain later returned the network online and reported on-chain restoration complete, while about 3.9 million unauthorized ORAI remained traced to MEXC and KuCoin for freeze-and-return efforts.

    ExploitNo canonical USD loss is assigned. Oraichain later reported approximately 3.9 million unauthorized ORAI still traced to centralized exchanges; that quantity is an outstanding-assets claim, not a gross-loss valuation.Unresolved
