The governing methodology is set out in full in the CCi30 Methodology Manual. The Index is administered in a manner aligned to the IOSCO Principles for Financial Benchmarks.
Calculation and publication
Cryptocurrency markets trade continuously. The Index is calculated on a twenty-four hour basis, seven days a week, and observes no market holidays.
Values published during a session are indicative. The value calculated at the official close is the sole official value for that session and is the value on which all published statistics, performance data and licensed reporting are based.
Where a material error in an official close is identified, a correction notice is published identifying the affected session, the erroneous value, the corrected value and the cause, and is issued to all entitled counterparties. Indicative intraday values are not restated, except that a restatement rescales them to agree with the restated closes (terms of use, clause 7.9).
Data access
Historical series
The complete daily series from inception is available for download in CSV format, together with constituent composition and weights. In the daily file, the volume column is the sum of the constituents’ 24-hour US dollar volumes. It is 0 from January 2015 to February 2018 and blank on 30 November 2020, 23 and 24 March 2023, 1 January 2025 and 1 July 2025: no volume was recorded on those days, and stored data cannot rebuild the published figures reliably, so none is shown.

Application programming interface
Index values are available programmatically over HTTPS in JSON format. Access requires an API key issued to a named counterparty.
Two entitlement tiers are operated:
- End-of-day. Official closing values, made available for non-commercial use under the terms of use.
- Real-time. Intraday values, available under licence. The current constituents and weights are open, under the same non-commercial licence as the end-of-day values.
Vendor and platform distribution
Index values can be delivered in counterparty-specified format and transport, including scheduled file delivery over SFTP, webhook delivery, and contribution to channels operated by receiving data vendors. Format, transport and redistribution rights are agreed at onboarding.
Data vendors and distribution platforms seeking to carry the CCi30 Index are invited to make contact. A Data Availability Sheet setting out full technical specifications is provided on request.

Independent validation
The CCi30 Index has been the subject of independent peer-reviewed academic examination. Alexander and Dakos (2020), published in Quantitative Finance, audited the construction and data integrity of the principal cryptocurrency indices then available and found that the CCi30 exhibited the highest accuracy among the indices examined.
