Solana, one of the key Ethereum competitors, started experiencing a minor service outage, according to its status page.
This came after the network suffered a widespread private key compromise.
More than 7,000 wallets have been drained of Solana (SOL) and Circle's USDC Coin (USDC) tokens. Phantom and other hot wallets have been affected by the incident.
It is believed that roughly $8 million worth of crypto has been stolen so far as a result of the attack.
At this point, it is unclear whether only the Solana blockchain has been affected by the attack.
In a lengthy Twitter thread, Ava Labs CEO Emin Gun Sirer opined that the bad actor managed to pull off the hack with the help of a supply chain attack by hijacking a JS library and exfiltrating users' private keys. He also suggested that a browser exploit could be in play, but such a scenario seems "highly unlikely."
The native Solana (SOL) token is down roughly 5% as a result of the attack. It is currently in ninth place by market cap.
While chipping away at Ethereum's market share due to its high scalability, Solana has faced plenty of technical difficulties. In June, the blockchain had been halted for four hours due to a bug related to cold storage transactions.
