The fund, set to trade under the ticker TOXR, is engineered to track the CME CF XRP-Dollar Reference Rate – New York Variant. This specific reference rate is crucial. It ensures the price investors see is derived from monitored, compliant data sources, addressing regulatory concerns about market integrity.
The operational efficiency relies heavily on authorized participants (APs). The agreement allows for APs to create or redeem shares both in-kind (by transferring physical XRP) and in cash. This dual mechanism is a technical best practice that ensures the fund’s share price remains tightly correlated with the net asset value (NAV) of the underlying XRP holdings.
The Custody Engine: Distributed Security

The 21Shares spot XRP ETF approval was supported by a robust security infrastructure. The technical design employs a multi-custodian structure to manage the fund’s physical assets. The chosen custodians—Coinbase Custody, Anchorage Digital Bank, and BitGo Trust Company—are all established entities. This approach mitigates operational risk by diversifying asset storage, ensuring that no single security event can compromise the entire reserve.
Furthermore, the annual sponsor fee of 0.3% is technically processed daily and paid weekly in XRP. This means the fund’s administrators are constantly engaging with the underlying asset, which is a key technical detail demonstrating operational competence.
Capital Injection: The $226M Seed

The seed capital provided by Ripple Markets—a substantial 100 million XRP, worth approximately $226 million—is a major technical factor. This initial injection provides the necessary depth for APs to start trading immediately without encountering undue liquidity friction. The size of this seed reflects the confidence in the 21Shares spot XRP ETF approval and its rapid market adoption, placing it immediately ahead of many smaller competitor products.
