According to 21Shares, the company has announced a global benchmark partnership with FTSE Russell to establish harmonized index frameworks across its ETF and ETP lineups in the US, Europe, and Australia. As reported by 21Shares, this partnership builds on the successful March 2026 transition of core European and Australian product lineups, including flagship Bitcoin, Ethereum, and Solana ETPs to FTSE Russell benchmarks. The US index transitions will officially take effect at market open on August 27, 2026, with the partnership designed to deliver institutional pricing integrity and governance framework to digital asset investors worldwide. The comprehensive rollout includes seven products transitioning to FTSE Russell indices: ARKB (Bitcoin ETF), TETH (Ethereum ETF), TSOL (Solana ETF), TOXR (XRP ETF), TSUI (Sui ETF), TDOG (Dogecoin ETF), and TDOT (Polkadot ETF).
According to the latest SEC filings, 21Shares Solana ETF will transition its NAV benchmark to the FTSE Solana Index under a new license with FTSE Russell, effective August 27, 2026. The new agreement provides a non-exclusive, worldwide right to use the FTSE Solana Index and carries a one-year initial term with automatic annual renewals. As reported by TradingView News, this transition will replace the CME CF Solana-Dollar Reference Rate as of August 27, 2026. The moves are specifically intended to support a smoother index transition and streamline administrative processes for the Solana ETF, with FTSE's digital asset index expertise reinforcing the ETF's benchmark methodology and supporting valuation and marketing of the trust.
On August 20, 2026, 21Shares US LLC entered into a licensing agreement with FTSE International Limited for benchmark access. According to the latest filings, the Benchmark Licensing Agreement provides a non-exclusive, non-transferable, non-sub-licensable, worldwide license to access the FTSE Sui Index for the development, creation, calculation, settlement, maintenance, and marketing of the 21Shares Sui Staking ETF. The license is expected to have a one-year initial term and will automatically renew for successive one-year periods unless terminated. This formal agreement follows 21Shares' notice on June 30, 2026 of terminating its licensing agreement with CF Benchmarks Ltd. for the CME CF Sui-Dollar Reference Rate, which expired on August 31, 2026.
On August 25, 2026, 21Shares US LLC filed a Certificate of Amendment to the Trust's Certificate of Trust with the Delaware Secretary of State to change the name from '21Shares Solana ETF' to '21Shares Solana Staking ETF'. As reported in the latest filings, on August 26, 2026, the company and CSC Delaware Trust Company entered into a Second Amended and Restated Trust Agreement to reflect the trust's use of the FTSE Solana Index, changes in sponsor fee timing, and the name change. The amendment also includes various ministerial, technical, conforming and clarifying revisions that none of which materially impact the rights of the trust or holders of shares. The 21Shares Ethereum ETF was previously renamed to 21Shares Ethereum Staking ETF on August 25, while the Polkadot (DOT) fund became the 21Shares Polkadot Staking ETF.
According to the latest filings, 21Shares US LLC and the 21Shares Sui Staking ETF entered into Amendment No. 1 to the Sponsor Agreement on August 26, 2026, changing the timing of payment of the sponsor fee from weekly in arrears to at least quarterly in arrears, payable in SUI. This represents a significant change from the previous weekly payment frequency and affects all five funds in the 21Shares ETF lineup. The amendment also includes changes to reflect the trust's use of the FTSE Solana Index, the change in timing of sponsor fee payment, and various ministerial revisions. The Bitcoin (BTC) fund and XRP and Dogecoin (DOGE) funds retained their original names during these changes.
