According to Crypto Rover, Canary has filed an updated version of its spot SOL ETF S-1 application, signaling renewed momentum for Solana-based exchange-traded funds (source: Crypto Rover on Twitter, May 21, 2025). This regulatory update is critical for traders, as ETF approval could drive institutional inflows into Solana, potentially strengthening SOL price action and increasing trading volumes. Market participants should closely monitor further filings and SEC feedback for near-term volatility and liquidity shifts across major crypto assets.
