Cross-chain liquidity protocol THORChain halted all trading after a potential security vulnerability was disclosed to the team.
THORChain developers opted to suspend the network on Tuesday as a cautionary measure as they investigated reports of an issue. The decentralized network facilitates token swaps between eight chains, including Bitcoin, Ethereum, Avalanche and Cosmos.
**THORChain Globally Halted**@ninerealms_cap and THORSec have received credible reports of a potential vulnerability affecting @THORChain. Out of an abundance of caution, steps have been taken to halt THORChain globally.
Stand by for more information.

Liquidity platform Nine Realms and security team THORSec found these reports to be credible. However, in order to exploit the vulnerability, a malicious node would have needed to act in the last churn.
“We are operating under the assumption that if a malicious validator had taken steps during the last keygen, they would have already used the exploit to steal from THORChain’s vaults,” said a THORChain developer “Pluto9R” on Twitter.
The issue relates to the Threshold Signature Scheme (TSS) and all churn functions on the network were halted as developers worked on a fix.
THORChain came back online around eight hours after the chain halt after determining that nodes would not be susceptible to an exploit.
Update: THORChain Unhalted
Devs & security teams have determined the claim is credible (relates to TSS) but no nodes can exploit current vulnerability. Churn is disabled pending fix.
Trading/LP/Savers Vaults have all resumed.

The protocol’s native token RUNE dropped to an intra-day low of $1.31 on Tuesday, down 5% over a 24-hour period.
This isn’t the first time the network has been suspended due to a software issue. In October, a bug that caused “non-determinism between individual nodes” led to a 20-hour outage on THORChain.
