This metric is an improved version of the legacy SplyExpFut10yr metric as it is better suited for use-cases that require a high degree of standardization, such as multi-asset indexes. As part of the v4.7 release, Coin Metrics has taken additional steps to harmonize the treatment of expected future supply across different token models. We have implemented these improvements in a this new metric; SplyExpFut10yrCMBI.
10 Year Expected Supply, Adj (native units)
SplyExpFut10yrCMBI
Native units
10 years
Expected future supply is computed by extrapolating the behavior of the currently active monetary policy.
The CMBI version of this metric takes extra steps to guarantee heuristics are uniformly applied to various cryptoassets.
Only implemented and programmatically defined supply inflation levels are considered. Any proposed or speculative inflation changes are not included until they are implemented in the source code as historically delays and governance processes have hindered such changes in a protocol’s monetary policy. Even if future changes in monetary policy are announced, they are only taken into account once they are enforced by the protocol.
Unless lost, burned, or vested on-chain beyond 10 years, all current on-chain supply will be deemed liquid supply in 10 years time. Coin Metrics has taken this approach to account for the unpredictability associated with determining what holders of restricted supply will do over the next 10 years. e assets, estimating this number relies on too many assumptions (staking ratio, etc..), in which case it is not computed.
Released in the 4.7 release of NDP
The sum of all native units counting current supply and including all those expected to be issued over the next 10 years from that day if the current known continuous issuance schedule is followed. Future expected hard-forks that will change the continuous issuance are not considered until the day they are activated/enforced.

Expected Future Supply metrics can be accessed using these endpoints:
timeseries/asset-metrics
and by passing in the metric ID's SplyExpFut*
in the metrics
parameter.
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:
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.
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.
["AdrActCnt","BlkHgt"]
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.

endpoint.

Available options: 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

. Inclusive by default. Mutually exclusive with start_height
and start_hash
. UTC timezone by default. Z
suffix is optional and timezone
parameter has a priority over it. If start_time
is omitted, response will include time series from the earliest time available.
End 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

. Inclusive by default. Mutually exclusive with end_height
and end_hash
. UTC timezone by default. Z
suffix is optional and timezone
parameter has a priority over it. If end_time
is omitted, response will include time series up to the latest time available.
The start height indicates the beginning block height for the set of data that are returned. Inclusive by default. Mutually exclusive with start_time
and start_hash
.
The end height indicates the ending block height for the set of data that are returned. Inclusive by default. Mutually exclusive with end_time
and end_hash
. This parameter is disabled for Community users.
The start hash indicates the beginning block height for the set of data that are returned. Inclusive by default. Mutually exclusive with start_time
and start_height
.
The end hash indicates the ending block height for the set of data that are returned. Inclusive by default. Mutually exclusive with end_time
and end_height
.
Inclusive or exclusive corresponding start_*
parameters.
true
Inclusive or exclusive corresponding end_*
parameters.
true
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).
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.
UTC
Example: America/New_York
Number of items per single page of results. The value of this parameter is ignored if the endpoint supports the format
parameter and its value is set to json_stream
.
100
Where does the first page start, at the start of the interval or at the end. The value of this parameter is ignored if the endpoint supports the format
parameter and its value is set to json_stream
.

Available options: How results will be sorted. Metrics with 1b
frequency are sorted by (asset, height, block_hash)
tuples by default. Metrics with other frequencies are sorted by (asset, time)
by default. If you want to sort 1d
metrics by (time, asset)
you should choose time
as value for the sort
parameter. Sorting by time
is useful if you request metrics for a set of assets.
asset
Available options: How many entries per asset result should contain. For example, this combination of parameters assets=btc,eth&metrics=ReferenceRate&limit_per_asset=1
returns the latest ReferenceRate
values for btc
and eth
.
Human-readable formatting of JSON responses.
false
Format of the response.
json
Available options: Nulls are represented as zeros in the response.
false
Token for receiving the results from the next page of a query. Should not be used directly. To iterate through pages just use next_page_url
response field.
Ignore "forbidden" errors for the items you currently don't have access to.
false
Ignore "unsupported" errors for not currently supported by Coin Metrics items.
false
Time series of asset metrics.
