TL;DR:
- Axelar disclosed a security incident that resulted in the loss of approximately $4.3 million in tokens bridged to Secret Network.
- The flaw originated in the ICS-20 smart contract on Secret’s side within the Cosmos IBC connection, without affecting the core protocol.
- The network’s emergency committee disabled connections with Secret and Secret-SNIP, and contacted several exchanges and law enforcement agencies.
Axelar Network disclosed a security incident that resulted in the loss of approximately $4.3 million in tokens bridged from its blockchain to Secret Network through the Inter-Blockchain Communication (IBC) protocol. According to the protocol team’s initial investigations, the issue originated in the ICS-20 smart contract located on Secret’s side within the Cosmos IBC connection, specifically in transfers flowing from Axelar toward that network.
As an immediate containment measure, the protocol’s emergency committee disabled connections with Secret and Secret-SNIP. In parallel, the team reached out to several cryptocurrency exchanges and law enforcement agencies to mitigate the impact and advance the investigation. The network also announced the publication of a detailed post-mortem of the incident to pinpoint its causes and document the resolutions adopted.
We have identified an incident affecting assets bridged over IBC to Secret Network from the Axelar chain, with approximately $4.67M worth of tokens taken. Based on current information, the issue is isolated to the Secret-side ICS-20 smart contract of the Cosmos IBC connection…

Limited Scope of the Exploit
One point highlighted by the company itself is the contained scope of the exploit: the incident appears to be confined to assets held on Secret Network and, more specifically, to those bridged from Axelar. No other IBC connection or network integration appears to have been compromised, which was key to preserving the functioning of the network’s core protocol.
The Impact on Axelar Ecosystem Confidence
A loss of funds of this magnitude in an interoperability protocol raises questions about the risks of managing assets and the bridging mechanisms between different blockchain networks. For those holding positions in assets related to Axelar or interoperability solutions within the Cosmos ecosystem, tracking the post-mortem conclusions will be key to assessing the real impact on confidence in these protocols.
The incident highlights the technical complexity involved in connecting heterogeneous networks and the exposure generated by third-party smart contracts when they operate as intermediaries in asset flows. The team’s swift response and the decision to communicate the event transparently are signals that the market will take into account when weighing the network’s operational soundness.
