On August 8, 2026, the Oraichain network was exploited via an unbacked cross-chain mint, allowing tokens to be minted without matching collateral on the origin chain. Flagged by the Oraichain team; the loss amount was not disclosed and no dedicated post-mortem has been published.

Oraichain (AI Layer 1) suffered from a vulnerability in its EVM cross-chain transfer path, enabling unauthorized minting of ORAI tokens. The network has been halted since 04:00 UTC on August 9, 2026, with bridges, cross-chain routes, and public interfaces restricted. The exploit path has been identified and addressed; the team is working with partners and CEXs to limit fund movements and is preparing to burn the unauthorized minted balances and reconcile protocol states to restore the canonical ORAI supply.
