TxTfrCnt

Transfers

1 day

Details

A transaction is comprised of one or more transfers between different entities. A single transaction may contain dozens of distinct transfers, which represent the movements of native units from one ledger entity to another distinct ledger entity. Only transfers that have a positive (non-zero) value are counted. Transfers have been colloquially referred to as "payments".
For ETH, we do not count failed transactions or self-sends towards TxTfrCnt. We do count internal transfers and do not distinguish them from top-level transfers. One way to think of TxTfrCnt is to count each time ETH effectively changes hands (excluding payment of fees and new issuance)

Asset Details

For SOL, we do not count failed transactions or self-sends towards TxTfrCnt. We do count internal transfers and do not distinguish them from top-level transfers. One way to think of TxTfrCnt is to count each time SOL effectively changes hands (excluding payment of fees and new issuance)

Chart

Examples

Consider a single Bitcoin transaction that represents a company's payroll. The company broadcasting this transaction spends one input and generates 12 UTXOs, one for each of its employees. In this example, that transaction would entail 12 transfers.

ERC-20 Xfer Cnt

Definition

The sum count of ERC-20 transfers in that interval. Only non-zero transfers between two distinct addresses are counted. 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.

Transfers

Details

This metric uses the ERC-20 specification Transfer event as the definition for ERC-20 transfer and only looks for transfers 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

ERC-1155 Xfer Cnt

Definition

The sum count of ERC-1155 transfers in that interval. Only transfers 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.

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 .

API Endpoints

Token Transaction metrics can be accessed using these endpoints:

timeseries/asset-metrics

and by passing in the metric ID's TxTfr*, etc. 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.

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: allPossible values:

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. 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_timestringOptional

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, 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.

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.

end_heightinteger · int64Optional

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.

start_hashstringOptional

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.

Inclusive or exclusive corresponding start_* parameters.

Default: true

end_inclusivebooleanOptional

Inclusive or exclusive corresponding end_* parameters.

Default: true

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.

Default: UTCExample: America/New_York

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.

Default: assetPossible values:
