Solana's decentralized application on-chain revenue plummeted to $22 million in June, marking an 18-month low, a significant decline from $36 million two months prior. The network is struggling to capture revenue from the lucrative perpetual futures market, which is currently dominated by other platforms. Meanwhile, SOL's price is facing pressure near the $87 support level, with derivatives data showing pessimistic market sentiment as funding rates stagnate and put options trade at a premium. A break below $87 could potentially retest $80.
