ZetaChain has paused all cross-chain transactions after an attack targeted its GatewayEVM contract. The protocol said the exploit hit only internal team wallets, with no user funds affected, and that the attack vector has been contained with no further losses expected.
Why it matters
A pause on a live cross-chain interoperability layer is a structural event for the protocol's user base. Even with no customer funds compromised, every cross-chain message — transfers, contract calls, swaps routed through ZetaChain's gateway — is on hold until the post-mortem confirms the surface is sealed. The team has flagged that a detailed write-up is incoming, which will determine how narrowly the fix needs to be scoped.
Market impact
The fact that the attacker reached the GatewayEVM contract at all is the part developers and integrators will be reading closely. Internal-wallet exposure suggests a privileged-key or operational-security gap rather than a user-deposit vulnerability, but the contract itself was reachable, and the response was a full network pause — the kind of move that tests trust in the team's incident response as much as the code's resilience.
Frequently asked questions
-
Did the ZetaChain hack affect user funds?
No. ZetaChain said the attack on its GatewayEVM contract hit only internal team wallets, with no user funds affected and no further losses expected.
-
Why did ZetaChain pause cross-chain transactions?
The protocol paused cross-chain transactions as a precaution while the investigation into the GatewayEVM contract attack continues. A detailed post-mortem is expected.
-
What is the GatewayEVM contract?
The GatewayEVM contract is the on-chain component that routes cross-chain messages and calls through ZetaChain. It was the target of the reported attack.
-
Has the ZetaChain attack been contained?
ZetaChain said the attack vector has been contained and that no further losses are expected, though the post-mortem has not yet been published.
-
When will ZetaChain resume cross-chain transactions?
ZetaChain has not given a specific resumption timeline. Cross-chain transactions remain paused until the investigation and post-mortem are complete.
