Current Supply (native units)

Definition

The sum of all native units ever created and currently visible on the ledger (i.e., issued) as of that day. For account-based protocols, only accounts with positive balances are counted.

Name	MetricID	Unit	Interval
Current Supply (native units)	SplyCur	Native units	All time

Details

• This metric might be also be characterized as “total issued supply” as it captures the sum of all native units visible in the ledger up until the metric calculation point

• For UTXO chains, current supply is the sum of all unspent output values.

• For account chains, current supply is the sum of all account balances.

Asset-Specific Details

• For ZEC, it includes the shielded pools value

• For Ripple, escrows are counted towards total current supply.

• For privacy coins like Monero or Grin, total current supply is computed by summing up mining rewards.

• For Solana, includes inflation from staking rewards and deflation from burnt coins

Release History

• Released in the 1.0 release of NDP

NDF (Network Distribution Factor)

Definition

The ratio of supply held by addresses with at least one ten-thousandth of the current supply of native units to the current supply.

Name	MetricID	Unit	Interval
NDF (Network Distribution Factor)	NDF	Dimensionless	1 day

Release History

• Released in the version 4.9 of Network Data Pro

Interpretation

NDF is one way to assess Supply Dispersion. This ratio encompasses a broader economic group, perhaps equivalent to a combination of the middle and lower classes. It is calculated by assessing the aggregate supply in addresses holding more than 0.01% of a cryptoasset’s supply and dividing that figure by the total supply.

SER (Supply Equality Ratio)

Definition

The ratio of supply held by addresses with less than one ten-millionth of the current supply of native units to the supply held by the top one percent of addresses.

Name	MetricID	Unit	Interval
SER (Supply Equality Ratio)	SER	Dimensionless	1 day

Charts

Of the assets shown above, Bitcoin has the highest SER, followed by Ether and Litecoin. The sustained increase in Bitcoin’s SER shows that, in spite of large institutions entering the space, Bitcoin is still very much a grassroots movement.

Interpretation

Supply Equality Ratio (SER). It is analogous to the 20:20 Ratio; a traditional wealth inequality metric that compares the average income of the richest 20% of a society to the poorest 20%. Instead of income, the SER looks at supply held by different accounts within a network. It compares the poorest accounts (the sum held by all accounts with a balance less than 0.00001% of the supply) against the richest accounts (the sum held by all the top 1% addresses).

A high SER signifies high distribution of supply.

While SER provides a novel look into supply distribution that is not possible with most traditional assets, an important caveat is that a single individual can own many cryptoasset addresses. As such, an individual might hold many addresses and supply distribution does not directly map to an individual’s holdings. Also, assets custodied by large financial institutions increases SER’s denominator and puts overall downward pressure on the ratio.

Definition

The sum of all native units ever created and visible on the execution layer ledger (i.e., issued) at the end of that interval. Developed for Ethereum total Supply Calculation.

Details

• This metric is specific to Ethereum and only available for eth.

• This supply value is one part of the input into the SplyCur calculation for Ethereum.

API Endpoints

Current Supply metrics can be accessed using these endpoints:

• timeseries/asset-metrics

and by passing in the metric ID's SplyCur in the metrics parameter.

Asset metrics

get

Returns requested metrics for specified assets. Results for block by block metrics (1b frequency) are ordered by tuple (asset, height, block_hash), all other metrics are ordered by tuple (asset, time). You can change the sorting using sort query parameter. Supported output formats are json (default) and csv, use format query parameter to override it. To fetch the next page of results use next_page_url JSON response field or x-next-page-url CSV HTTP header if present. If multiple metrics are requested in the same time the strict policy for partially available metrics among requested ones is applied:

Authorizations

Query parameters

assetsstring[]required

Comma separated list of assets. Use the /catalog-all/assets endpoint for the full list of supported assets or specify asterisk (*) in order to get metrics for all supported assets.

metricsstring[]required

Comma separated metrics to request time series data for. Information on all available metrics can be found on page https://coverage.coinmetrics.io/asset-metrics-v2. Use the /catalog-all/metrics or /catalog-all/assets endpoint for the full list of supported metrics per asset.

Example: ["AdrActCnt","BlkHgt"]

frequencystringoptional

Frequency of the metrics. Supported values are 1b (block by block), 1s (one second), 1m (one minute), 5m (five minutes), 10m (ten minutes), 1h (one hour), 1d (one day), 1d-ny-close (one day at New York close time). Please refer to the /catalog/metrics endpoint for the full list. Use the /catalog-all/assets endpoint for the full list of supported frequencies per asset-metric pair.

Default: 1dExample: 1b

statusstring · enumoptional

Which metric values do you want to see. Applicable only for "reviewable" metrics. You can find them in the /catalog/metrics endpoint.

Default: allAvailable options:

start_timestringoptional

Start of the time interval. This field refers to the time field in the response. Multiple formats of ISO 8601 are supported: 2006-01-20T00:00:00Z, 2006-01-20T00:00:00.000Z, 2006-01-20T00:00:00.123456Z, 2006-01-20T00:00:00.123456789Z, 2006-01-20, 20060120. Inclusive by default.

min_confirmationsinteger · int32 · max: 99optional

Specifies how many blocks behind the chain tip block by block metrics (1b frequency) are based on. Default for btc is 2 and 99 for eth. For example, a min_confirmations of 0 means metrics are being calculated for the block at the tip of the chain (the latest block received by our node) whereas a min_confirmations of 6 means that metrics are being applied to the block that is 6 blocks behind the chain tip (i.e., the 7th block if the chain tip is block 1).

timezonestringoptional

Timezone name for start_time and end_time timestamps. This parameter does not modify the output times, which are always UTC. Format is defined by TZ database.
