Headline: Axelar disables Secret Network bridge after ~$4.7M IBC exploit
Axelar has shut down its bridge connections to Secret Network after an incident that led to the theft of about $4.67 million in bridged tokens. The interoperability protocol says the loss involved assets moved from the Axelar chain to Secret via the Cosmos Inter-Blockchain Communication (IBC) framework.
Initial investigation points to the Secret-side ICS-20 contract — the component that handles IBC token transfers on Secret Network — rather than Axelar’s core infrastructure. Axelar’s statement said the issue appears isolated to that contract on Secret’s side and that there is currently no evidence other IBC channels, Secret-native assets, or additional Axelar integrations were affected. Axelar’s core protocol remained operational throughout.
Immediate response
- Axelar’s emergency committee disabled the Secret and Secret-SNIP connections to stop further losses.
- The team notified relevant exchanges and law enforcement and is continuing its forensic review.
- A full post-mortem will be published once the investigation is complete. Until then, the affected bridge routes will stay offline while engineers trace the attack path and quantify the damage.
Why this matters
Secret Network is a privacy-focused blockchain that encrypts transaction data while keeping smart contract code verifiable on-chain. Through its Axelar integration, developers have been able to build private cross-chain applications — from confidential DeFi activity and private NFTs to anonymous governance. The exploit therefore affects users relying on those private cross-chain flows rather than Secret’s native assets.
Wider context
This incident adds to a wave of recent security problems hitting crypto infrastructure. Earlier in June, Humanity Protocol disclosed an exploit that prompted it to retire its original H token; affected users are to receive replacement tokens via an audited ERC-20 airdrop, and Humanity blamed stolen credentials for that breach. Crypto payments provider Pyra also announced plans to wind down operations after the Drift exploit left it unable to recover. Meanwhile, Binance Research has noted that April’s DeFi exploits contributed to roughly $13 billion in TVL outflows and pushed on-chain leverage to levels not seen since 2021.
What’s next
Axelar says it will share more details after the investigation concludes. For now, users and projects relying on the Axelar–Secret bridges should assume those routes are disabled and monitor official Axelar and Secret Network channels for updates.
