A recently discovered 
Zcash matching bug has resulted in a loss of approximately 140 RUNE for 18 THORChain node operators. The incident occurred due to an error in the cross-chain asset matching mechanism, which led to the slashing of the node operators' bonds.
Despite the loss incurred by the node operators, user funds remain unaffected by the bug. This suggests that the protocol's safeguards were effective in protecting user assets, even as the node operators bore the brunt of the error.
The issue has prompted THORChain to halt ZEC swaps until the platform is updated to version v3.21, which is expected to address the bug. This precautionary measure aims to prevent further incidents and ensure the stability of the platform.
The broader market context shows a relatively flat overall crypto market, with 
Bitcoin up 0.93% in the past 24 hours. Interestingly, Zcash itself saw a significant 9.62% price increase during the same period, despite the incident.
The incident underscores the risks associated with decentralized protocols and the importance of robust security measures. As the crypto space continues to evolve, such incidents highlight the need for ongoing vigilance and updates to protect both node operators and users.

The chart plots ZEC's price: grey is the move before this brief published, the vertical dashed line marks the moment it published, the horizontal dashed line is the price then, and the coloured area is the move since — from TLT's market data (daily resolution). It shows what happened after the news, not that the news caused it; many factors move prices. Not financial advice.
At today's peer-to-peer rate, 1 ZEC ≈ ₦1.72M (about $1,263.53), up 11.2% over 24 hours. The naira itself trades about 2.3% above the official rate on the P2P market, so a Nigerian buyer's effective cost differs from the headline dollar price.
