TLDR
- THORChain restores swaps after fixing its $10.7M exploit
- Vault migration and keyshare checks cleared the restart path
- Zcash support now moves toward launch after network recovery
- Monero swaps remain next after successful end-to-end testing
- TAO support may follow as THORChain rebuilds network activity
THORChain restored full network operations after security upgrades addressed flaws linked to a $10.7 million exploit. The protocol reopened swaps, signing, liquidity actions, and vault activity after more than one month offline. The restart followed vault checks, keyshare verification, node upgrades, and migration away from older infrastructure.
THORChain Completes Vault Migration and Security Checks
THORChain halted trading on May 15 after attackers exploited a weakness in its GG20 threshold signature system. The flaw exposed key material over time and allowed a malicious node operator to rebuild a private key. That access enabled the theft of $10.7 million from protocol vaults.
Developers issued an emergency patch on May 20 to protect funds held in the remaining active vaults. THORChain then released a larger upgrade on June 9, which fixed the exploited signing weakness. A June 11 update added stability improvements and corrected problems affecting the KeyVerify process.
The protocol later used KeyVerify to confirm the safety of most vaults and verify every node keyshare. It also retired legacy vaults and moved assets into a new vault set before restoring activity. Signing, churning, secured assets, trade assets, liquidity actions, and swaps returned across the network.
Zcash Integration Follows Network Restart
THORChain plans to add native Zcash swaps and vault support within two weeks of the restart. The integration will allow direct ZEC trading without wrapped tokens or centralized intermediaries. The protocol has not provided a specific launch date for the planned support.
The Zcash rollout will expand the protocol’s cross-chain market beyond established assets such as Bitcoin and Ethereum. THORChain already enables users to move value directly between supported blockchains through decentralized liquidity pools. The new integration will add another privacy-focused asset to that system.
Developers will monitor vault performance and signing activity during the first weeks after reopening. Meanwhile, node operators will continue supporting network security through distributed key management and transaction approval. The protocol has placed stability ahead of faster expansion during the recovery process.
Monero and Bittensor Support Remain in Development
THORChain also plans to launch native Monero swaps after completing the Zcash integration. The team said end-to-end XMR swap testing already works, while a live release remains ahead. Native support would connect Monero directly with other assets available through the protocol.
The project also expects to add Bittensor support about six weeks after the network restart. That integration would bring TAO into THORChain’s decentralized cross-chain trading system. Still, the stated timeline depends on continued network stability and successful technical preparation.
The restart marks the end of the protocol’s longest recent operating pause. THORChain now returns with patched signing software, verified keyshares, and a newly migrated vault structure. Its next phase will focus on stable operations, new assets, dynamic fees, and deeper liquidity.
