Solana (SOL) has maintained its position above the $140 mark despite a recent $37 million hack on the Upbit exchange, which involved SOL and Solana-based tokens. Upbit has temporarily halted operations and committed to reimbursing affected users. In a separate development, Franklin Templeton has filed a Form 8-A with the U.S. Securities and Exchange Commission to launch a Solana ETF, indicating increasing institutional interest in the blockchain. Analysts believe the ETF could boost long-term adoption, although its immediate market impact is uncertain. On-chain data reveals strong buying activity at key support levels, with traders focusing on the $142–$145 range as potential resistance.
