Notice of the Demising of CF IoTeX-Dollar Spot Rate

The Administrator announces that it will demise the CF IoTeX-Dollar Spot Rate (IOTXUSD_RTI) which is a member of the CF Digital Asset Index Family.

Rationale and Timeline of Events
The original input data sources for the CF IoTeX-Dollar Spot Rate were Coinbase; Gemini and Crypto.com.

Gemini ceased its support for the IOTX on May 21st, 2026, and was suspended as a Constituent Exchange on June 08th, 2026.

The Administrator also had previously reported the CF IoTeX-Dollar Spot Rate calculation failure on May 08th, 2026. Following continued calculation failures, primarily resulting from severe service disruptions at Coinbase as detailed in the relevant announcement, the Administrator decided to temporarily suspend Coinbase as the CF Constituent Exchange for the CF IoTeX-Dollar Spot Rate on May 09th, 2026. As Coinbase has since recovered from the original outage, the Administrator made a decision to re-admit Coinbase as a CF Constituent Exchange on June 08th, 2026.

After readmitting Coinbase June 08th, 2026 the Administrator observed another calculation failure event of the CF IoTeX-Dollar Spot Rate on June 09th, 2026. The calculation failure occurred because the Relevant Order Books of all CF Constituent Exchanges were flagged as potentially erroneous due to significant price differences observed across the remaining two CF Constituent Exchanges Coinbase and Crypto.com.

The Administrator does not believe that the significant price differences observed between the remaining CF Constituent Exchanges are temporary in nature. Accordingly, the CF IoTeX-Dollar Spot Rate will continue to generate calculation failures.

For the reasons outlined above, the Administrator has decided to cease publication of the CF IoTeX-Dollar Spot Rate.

Alternative Benchmarks
IoTeX - Dollar Market Price (U_IOTXUSD_RTI), please note input data and input data sources will vary between the CF IoTeX-Dollar Spot Rate and the IoTeX - Dollar Market Price.

Implementation Date
Accordingly, the Administrator will demise the benchmarks at around 11:00 London Time on June 15th, 2026.

This means the final value of the CF IoTeX-Dollar Spot Rate will be published at approximately 11:00 London Time on June 15th, 2026.

The CF Cryptocurrency Index Family Oversight Function has reviewed this demising process.

Pricing the Perp DEX Leader: A Valuation Framework for Hyperliquid
