Base Fee for Block

Definition

The base fee of the most recent block processed.

Dictionary

Name	MetricID	Unit	Interval
Base Fee for Block	block_base_fee	ETH	1b

Methodology

The most recent block we processed within a 1-minute window is evaluated and its Base Fee captured. The concept of a Base Fee was introduced as part of EIP-1559 and it represents the portion of the total transaction fees that is destroyed and taken out of circulation (i.e. burnt). Ethereum post-1559 requires users to pay for a Base Fee as a prerequisite to include transactions in a block. The Base Fee can go up or down on the basis of the size (in gas units) of the previous block.

Priority Fee for Block

Definition

The priority fee, or tip, of the most recent block processed.

Dictionary

Name	MetricID	Unit	Interval
Priority Fee for Block	block_priority_fee	ETH	1b

Methodology

The most recent block we processed within a 1-minute window is evaluated and its Priority Fee, or tip, is captured. The concept of a Miner Tip was introduced as part of EIP-1559 and it represents the portion of the total transaction fees that rewards miners. This serves as an added incentive so that miners prioritize transactions that have opted-in and paid a tip. The other portion is called the Base Fee, and it is burnt (destroyed) after the transaction is included in a block.

API Endpoints

metrics can be accessed using these endpoints:

• timeseries/asset-metrics

and by passing in the metric ID's block_*_fee in the metrics parameter.

Asset metrics

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:

GEThttps://api.coinmetrics.io/v4/timeseries/asset-metrics
