Qubic's layer-1 blockchain was suspended after an exploit led to the theft of 2.94 trillion QU tokens from over 1,400 accounts. Solana (SOL) is trading at ₹10,048 ($105.56), down 0.1% since this brief published. This is an original Token Times brief based on reporting by Crypto.news, with live market data added, as of Mon, 19 Oct 2026 08:15:01 UTC.
The incident highlights vulnerabilities in layer-1 blockchain security and the challenges of protecting user assets, potentially impacting investor confidence in smaller blockchain ecosystems.
- Qubic blockchain halted after $1.4M hack exploiting security flaw.
- Attack affected 2.94T QU tokens across 1,400+ accounts.
- Solana's ecosystem growth contrasts with Qubic's security incident.
Qubic's layer-1 blockchain has been temporarily suspended following a security breach that resulted in the theft of approximately 2.94 trillion QU tokens, valued at around $1.4 million, from more than 1,400 user accounts. The Qubic core team announced the halt in an Oct. 18 statement, citing a vulnerability in wallet security as the cause of the exploit.
The incident underscores the ongoing challenges faced by smaller blockchain projects in securing their networks against sophisticated attacks. While Qubic's team has not yet provided details on how the exploit was executed, the suspension of the blockchain suggests they are working to address the vulnerability and prevent further losses.
In contrast to Qubic's security issues, 
Solana's ecosystem has been experiencing significant growth. Multiple outlets report that Solana now has over 1.4 million active addresses, and its DeFi TVL stands at $5.9 billion, according to DeFiLlama. This growth highlights the divergent fortunes of different blockchain projects in the current market environment.
The broader crypto market remains in a state of cautious optimism, with the total market cap at $2.83 trillion and 
Bitcoin up 1.27% in the last 24 hours. The Fear & Greed Index currently stands at 59, indicating a 'Greed' sentiment among investors. Solana's native token, SOL, is also performing well, trading at $105.67 with a 1.97% increase in the past day, though it has seen a 6.60% decline over the last week.
The Qubic hack serves as a reminder of the importance of robust security measures in the crypto space. As the investigation into the incident continues, the market will be watching to see how Qubic addresses the issue and whether similar vulnerabilities exist in other blockchain networks.
Since this brief published about 3 hours ago, Solana (SOL) has moved from ₹10,058.19$105.67 to ₹10,047.72$105.56 — -0.10%.
The chart plots SOL'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 Token Times'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 SOL ≈ ₹11,017.83 (about $105.56), up 2.3% over 24 hours. The rupee itself trades about 9.7% above the official rate on the P2P market, so a Indian buyer's effective cost differs from the headline dollar price.
