Insights

ETF Structuring Specialist

Permits standard ETF in-kind mechanisms using SOL.

The supplement replaces a prior restriction by expressly allowing in-kind creations and redemptions in exchange for SOL, effective May 13, 2026. This aligns the Trust’s mechanics with common ETF practice where authorized participants transact securities or underlying assets in-kind.

Practical dependencies include the operational readiness of Authorized Participants and the Transfer Agent to accept and deliver SOL. Subsequent filings or prospectus updates may disclose participating counterparties, custody arrangements, or operational procedures.

Regulatory Compliance Analyst

Disclosure change clarifies permitted creation/redemption methods.

The Prospectus Supplement amends the April 16, 2026 prospectus by removing the sentence that the Trust "is not at this time able to create and redeem shares via in-kind transactions with Authorized Participants." The supplement controls to the extent of any inconsistency.

Investors should note that the Trust remains listed on NYSE Arca under the symbol GSOL and that risk disclosures remain in the Prospectus. Any further material operational details would be expected in future filings or prospectus updates.

"Authorized Participants or their designees in exchange for SOL"

Authorized participants are a small group of large financial firms that have a formal arrangement with an exchange-traded fund (ETF) or similar product to create and redeem shares directly with the issuer. They act like wholesalers for the fund, supplying or removing shares to keep the market price in line with the value of the underlying assets; their activity affects an ETF’s liquidity, trading costs and how closely it tracks its target holdings.
