Grayscale Solana Staking ETF — Form 8-K

On August 6, 2026, Grayscale Investments Sponsors, LLC and CSC Delaware Trust Company executed a Third Amended and Restated Declaration of Trust for the Grayscale Solana Staking ETF (assets ~$105.1M). The amendment restates the entire trust agreement, incorporating three prior amendments (Sept 2025, Oct 2025, Jan 2026, June 2026). Key changes enable staking of SOL while maintaining grantor trust tax status, establish a Sponsor's Staking Fee (percentage of staking rewards, amount TBD in SEC filings), clarify liquidity management solutions, and define procedures for cash-based creations/redemptions. The filing contains no specific dollar amounts, share counts, or pricing changes—it is a governance restatement effective at Sponsor's discretion.
