1. Introduction to Binance Digital Asset Indices
1.1 Overview
Binance Digital Asset Indices are a suite of indices that track the performance of their underlying digital assets using various construction methodologies.
The suite of indices aims to provide representable and transparent benchmarks that track the overall digital asset and cryptocurrency markets.
Binance Digital Asset Indices are constructed with robust and industry standard index calculation methodologies and rebalancing approaches.
1.2 Indices
Binance CoinMarketCap(CMC) Top 10 Equal-Weighted Index
Binance CMC Top 10 Equal-Weighted Index aims to track the performance of the top 10 digital assets by market capitalization, relative to the base currency of USD. The basket of 10 digital assets is equally weighted and is rebalanced on a monthly basis. The index currency is USD.
The market capitalization of a digital asset is calculated by multiplying its reference price in USD by its current circulating supply at a specific time of the day. All times used in this document are UTC+0 time.
1.3 Pricing and Reference Data Source
Binance Digital Asset Indices use CoinMarketCap, a cryptocurrency data provider, as the data source for digital asset pricing.

2. Construction Methodology
2.1 Eligibility Criteria
Digital assets that may form part of the Binance Digital Assets Indices are those that are listed on both
https://binance.com, the Binance Exchange Platform, and
https://coinmarketcap.com/, the CoinMarketCap. This includes any digital asset listed on both the Binance Exchange Platform and CoinMarketCap, regardless of the listing base currency. If the base currency of the digital asset is not the same as the index currency, the cross-currency conversion will be applied across (BTC / index currency) to obtain a quote of the (digital currency / index currency).
2.2 Filtering Criteria
Digital assets will only form part of Binance Digital Asset Indices if they satisfy the following filtering criteria:
•have been listed on the Binance Exchange Platform and CoinMarketCap for at least 30 days;
•are not wrapped, pegged to another digital asset, non-digital (Fiat) currencies, group of those currencies, or physical assets;
•are not algorithmic stablecoins;
2.3 Liquidity Criteria
Digital assets will only form part of Binance Digital Asset Indices if they satisfy the following liquidity criteria:
Average Daily Trading Volume
$${ADTV_t} \geqslant {ADTV_{0.25}}$$
Where
•\(\mathbf{ADTV_{0.25}}\): The 25th percentile of the average daily traded volume of all eligible digital assets over the past rebalancing period.
•\(\mathbf{ADTV_{t}}\): The average daily traded volume of a single digital asset over the past rebalancing period.
2.4 Ranking
All eligible digital assets will be ranked by the 7-day average market capitalization (quoted in USD), as of the index rebalancing date.
2.5 Selection
The top 10 digital assets will be included in the index at each rebalancing according to the following process:
1. Rank the digital assets by market capitalization, with the highest ranked 80% of the basket size of the respective index automatically selected for inclusion.
2. Current digital assets ranked in the top 120% of the basket size of the respective index are selected until the basket size is met.
3. If the basket size is still not met, the highest-ranking non-constituent digital asset is selected and added to the index until the basket size is reached.
2.6 Weighting
Binance CMC Top 10 Equal-Weighted Index is an equally-weighted index. For this index, each underlying digital asset maintains a constant index weight of 10%.
2.7 Index Maintenance
Index Maintenance includes monitoring and implementing the adjustments due to hard forks, airdrops, mapping and / or other actions. The treatment of such actions will be evaluated by the Governance Committee from the qualitative and quantitative characteristics of each component digital asset.
2.8 Index Rebalancing
The indices rebalance monthly with the index rebalancing date on the fourth Monday of every month, and the data used for all the rebalance procedures will be before 0:00 UTC+0 of the rebalancing date. The publication date of the new rebalance selection is the first Wednesday immediately after the index rebalancing date. The implementation date of the new rebalance selection is the first Friday immediately after the index rebalancing date.
On the index rebalancing date, the index rebalancing process is applied in the following order:
•Determine the eligible digital assets as per Section 2.1.
•Apply filtering criteria as per Section 2.2.
•Apply the liquidity criteria as per Section 2.3.
•Rank the eligible digital assets as per Section 2.4.
•Select the index underlying digital assets following the rules of Section 2.5.
•Weight the index underlying digital assets as per Section 2.6.
The new selection of digital assets, and corresponding weights, become effective on the implementation date immediately following the rebalancing date.

2.10 Index Calculation
Index Returns
There is a single component to the index returns; the performance (appreciation / depreciation) of the underlying digital assets relative to the index currency.
Daily Index Calculation
All equal-weighted indices are calculated in accordance with the formula below.
$${\it {Index\ Level}_t} = {\it Base\ Level} \ast \left( \sum_{i=1}^n w_{{t_0},i} \ast \frac{s_{t,i}}{s_{{t_0},i}} \right) / {\it divisor_t}$$
Where,
•\(\mathbf{{Index\ Level}_t}\): Index level as of time t.
•\(\mathbf{Base\ Level}\): Index level as of the base date (t=0).
•\(\mathbf{w_{{t_0},i}}\): Weight of the \(\ i^{t_h} \) underlying digital asset as of the latest rebalance time, \(t_0\).
•\(\mathbf{s_{t,i}}\): Spot rate of the underlying digital asset as of time t, measured as (index currency / digital currency).
•\(\mathbf{s_{{t_0},i}}\): Spot rate of the underlying digital asset as of the latest rebalance time \(t_0\), measured as (index currency / digital currency).
•\(\mathbf{n}\): Number of underlying digital assets in the index.
•\(\mathbf{divisor_t}\): index divisor at time t which is used to maintain the continuity of the index level independent of rebalancing.
The index divisor is calculated as follows:
At the index base date (t=0), the divisor is initially fixed at 1, that is, \({\it divisor_0}\)=1. Subsequently, the divisor at any time t remains the same unless there is an index rebalancing. When an index rebalancing happens, an adjustment is triggered and the divisor is recalculated according to the formula
$${\it divisor_a} = {\it divisor_b} \ast \left( \sum_{i=1}^n w_{{t_a},i} \ast \frac{s_{a,i}}{s_{{t_a},i}} \right) / \left( \sum_{i=1}^n w_{{t_b},i} \ast \frac{s_{b,i}}{s_{{t_b},i}} \right)$$
, where b and a denote before and after the event of rebalancing. And ta, tb mean the latest rebalancing times before time a and time b respectively.
2.11 Index Dissemination
The index levels will be calculated and published every 60 seconds.
The index will be active and calculated live during all trading hours of the Binance Exchange Platform.
The daily index “close levels” is defined to be the index level as of 24:00 UTC Time. This time is synced with the rest of the Binance Exchange Platform in terms of daily closing levels of all tradable products.
3. Policy
3.1 Market Disruption Events
A market disruption event is any unscheduled event that could potentially impact the calculation and/or the publication of any of Binance Digital Asset Indices. The unscheduled events may be attributed to issues such as data sources, internal operational issues, publication delivery issues or extreme volatility.
In the case of the occurrence of such events, there may be a temporary halt to the index calculation.
3.2 Digital Assets Suspension or Delisting
If any digital assets are suspended or delisted from the Binance Exchange Platform, impacted indices will be made insensitive to the suspended or delisted underlying digital asset.
For the case of a suspended underlying digital asset, the underlying digital asset will be reviewed on a case-by-case basis to determine if the underlying digital asset should be permanently removed from the index underlying digital assets basket.
In the case of permanent removal of an underlying digital asset from an index. The index calculation will be made insensitive to such an underlying digital asset. The Binance Index Governance Committee will review and decide whether the next most eligible new digital asset will be added to the index immediately, or if the underlying digital asset replacement will take place in the following rebalance period.
4. Governance
4.1 Governance Committee
The Binance Index Governance Committee seeks to meet on a quarterly basis to review all the index methodologies. The Committee may conduct additional meetings in circumstances deemed necessary. The members of the committee must declare any potential conflicts of interests that may influence, in any way, their opinions and/or decisions during any committee meetings.
