ETF Operations Analyst

Benchmark swap is administrative but impacts NAV data sourcing.

The Pricing Benchmark Licensing Agreement provided a license to use the CME CF Solana-Dollar Reference Rate for daily valuation and NAV calculation. FTSE is identified as the incoming provider and is described as experienced in calculating digital asset indices.

The filing preserves that both CF Benchmarks and FTSE are unaffiliated with the Sponsor. Timing stated: notice June 30, 2026; CF Benchmarks termination effective August 31, 2026; FTSE license expected on or about August 24, 2026.

"used to value the Trust’s shares on a daily basis and to calculate the Trust’s net asset value"

Net asset value is the total value of an investment fund's assets minus any liabilities, divided by the number of shares or units outstanding. It represents the per-share worth of the fund, similar to how the value of a house is determined by its total worth after debts are subtracted. Investors use it to gauge the true value of their holdings and to compare different investment options.
