Chain Metrics
Daily chain-level aggregates including transaction counts, active addresses, gas usage, and contract deployments.
3 tables.
| Table | Chain |
|---|---|
agent.ethereum_chain_daily | Ethereum |
agent.base_chain_daily | Base |
agent.arbitrum_chain_daily | Arbitrum |
What's Included
Daily aggregates in the style of Artemis ez_metrics:
- Transaction count
- Active senders / receivers (HLL approximate, ~2% error)
- Average gas price (Gwei)
- Total native value transferred (ETH, not USD)
- Contract deployments
Good to Know
- Active address counts use HyperLogLog (
uniq()) — approximately 2% error margin, not exact. - Native value transferred is in ETH, not USD — join with prices tables for valuation.
- For L2s (Base, Arbitrum): gas price reflects L2 execution gas only, excludes L1 data posting fees.
- Contract deployments on Base/Arbitrum are typically higher than Ethereum due to lower gas costs.
