Token Tx Cnt

Definition

The sum count of transactions that resulted in any token (ERC-20 or ERC-721) activity in that interval. Only Transfer or Approval events are counted as activity. If a transaction results in more than 1 transfer or approval, it’s only counted once.

Details

• This metric counts only the ERC-20 and ERC-721 specification Transfer and Approval events.

Asset-Specific Details

• This metric is only available for ETH and ETC.

ERC-20 Tx Cnt

Definition

The sum count of transactions that resulted in any ERC-20 activity in that interval. Contracts that contain all of the following are considered to be ERC-20 contracts: the balanceOf function, the transfer function, and the Transfer event hash. Only Transfer or Approval events are counted as activity. If a transaction results in more than 1 transfer or approval, it’s only counted once.

Name	MetricID	Unit	Interval
ERC-20 Tx Cnt	TxERC20Cnt	Transactions	1 day

Details

• This metric counts only the ERC-20 specification Transfer and Approval events emitted by contracts detected as ERC-20 following the criteria outlined in Contracts, ERC-20, count.

• Full compliance with the ERC-20 standard is not required as only few ERC-20 tokens attain it. We therefore look for the bare minimum methods and events necessary for wallet integration of the token: balanceOf and transfer functions as well as the Transfer event. If a contract’s code has all of the following markers, it is considered to be ERC-20:

  • Signature of the balanceOf function: 6370a082311461

  • Signature of the transfer function: 63a9059cbb1461

  • Hash of the transfer event ddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef

Asset-Specific Details

• This metric is only available for ETH and ETC.

ERC-721 Tx Cnt

Definition

The sum count of transactions that resulted in any ERC-721 activity in that interval. Only transfers between two distinct addresses are counted. ERC-165 is used to determine a contract’s compliance with ERC-721. Only Transfer or Approval events are counted as activity. If a transaction results in more than 1 transfer or approval, it’s only counted once.

Name	MetricID	Unit	Interval
ERC-721 Tx Cnt	TxERC721Cnt	Transactions	1 day

Details

• This metric counts only the ERC-721 specification Transfer and Approval events emitted by ERC-721 compliant contracts.

• ERC-721 contracts are detected if they implement the ERC-165-compatible interface defined in the ERC-721 specification using the procedure specified in the ERC-165 specification.

• This metric is only available for ETH and ETC.

ERC-1155 Tx Cnt

Definition

The sum count of ERC-1155 transactions in that interval. Only transactions between two distinct addresses are counted. The ERC-1155 standard is an emerging standard for the issuance of both fungible and non-fungible tokens on Ethereum. As of this metric's release date, the standard has attained considerable traction in the ecosystem of Non-Fungible Tokens.

Name	MetricID	Unit	Interval
ERC-1155 Tx Cnt	TxERC1155Cnt	Transfers	1 day

Details

• This metric is calculated by monitoring the blockchain for ERC-1155 Transfer Events, as defined by the EIP-1155 Standard Specification.

• Like ERC-721 contracts, the activity of ERC-1155s is detected with the help of a secondary standard, ERC-165, which provides an interface for both 751 as well as 1155-compliant events.

Asset-Specific Details

• As this metric is tailored to the Ethereum ecosystem, it is only available for ETH .

Release History

• Released in Network Data Pro (NDP) version 5.1

API Endpoints

Token Transaction metrics can be accessed using these endpoints:

• timeseries/asset-metrics

and by passing in the metric ID's TxTknCnt, TxERC721Cnt, etc. in the metrics parameter.

Asset metrics

get

Returns requested metrics for specified assets.<br/><br/> 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.<br/><br/> Supported output formats are json (default) and csv, use format query parameter to override it.<br/> To fetch the next page of results use next_page_url JSON response field or x-next-page-url CSV HTTP header if present.<br/><br/> If multiple metrics are requested in the same time the strict policy for partially available metrics among requested ones is applied: <ul>

<li>missing metric name in the JSON response means that the metric is "not a supported metric" for the asset and frequency while some other requested metrics are supported.</li> <li>`null` value of the metric means "no data in the database" while some other requested metrics have data.</li> </ul>

Authorizations

Query parameters

assetsstring[]required

Comma separated list of assets.<br/> 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.<br/> Information on all available metrics can be found on page https://docs.coinmetrics.io/info/metrics.<br/> Use the /catalog-all/metrics or /catalog-all/assets endpoint for the full list of supported metrics per asset.

The start height indicates the beginning block height for the set of data that are returned.<br/> Inclusive by default. Mutually exclusive with start_time and start_hash.

end_heightinteger · int64

The end height indicates the ending block height for the set of data that are returned.<br/> Inclusive by default. Mutually exclusive with end_time and end_hash.<br/> This parameter is disabled for Community users.

min_confirmationsinteger · int32 · max: 99

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).

sortstring · enum · default: asset

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.<br/> Sorting by time is useful if you request metrics for a set of assets.
