DAU, TXNS, FEES, REVENUE and NEW_USERS are the same on-chain activity metrics Artemis uses for protocols and apps. CHAIN_DAU, CHAIN_TXNS, CHAIN_FEES, CHAIN_TVL and the rest of the CHAIN_* family measure the base layer specifically. Activity counts (TXNS, CHAIN_TXNS, FEES, CHAIN_FEES) are daily sums; user counts (DAU, NEW_USERS, CHAIN_DAU, CHAIN_MAU) are daily averages; CHAIN_TVL is an end-of-day snapshot.
Chains are the largest metric surface in the API. eth alone supports 104 metrics. The table below is a core set for cross-chain comparison; call GET /supported-metrics/ on any chain symbol for the rest.
Metrics
DAU is defined as addresses using a protocol’s products; CHAIN_DAU is specifically addresses that send a transaction on the chain. For eth, trx and sol on 2026-08-01 the two returned identical values. FEES and CHAIN_FEES do diverge on eth: FEES also folds in application-level fees from DeFi protocols built on top of the chain, on top of raw gas: $193,124.92 versus CHAIN_FEES’s $193,103.06 on the same day.
Covered chains
Artemis covers 112 chains, including:eth · sol · btc · base · arb · bnb · trx · op · pol · avax · sui · apt · near · ton · hype · linea · xrp · ada · unichain · mnt
For the full list, filter GET /asset/ by sector.
Example: Daily users, transactions, fees and revenue
Because this request uses
summarize=true, every figure above is the 2026-08-01 value, not an eight-day total. summarize returns the endDate day regardless of whether a metric is SUM, LAST or AVERAGE. See Core concepts.
Fees and revenue aren’t the same quantity, and /supported-metrics/ explains why they diverge here. Solana’s REVENUE description specifically includes “Jito tips accruing to SOL stakers” on top of base, priority and vote fees (value FEES doesn’t count), which is why revenue ($522,786) comes in above fees ($423,018). Arbitrum’s REVENUE is defined as fees paid to the sequencer minus the cost of posting that transaction data back to Ethereum mainnet, which is why its revenue ($3,494) sits far below its fees ($13,180).
Chain TVL
Split by category
Chain-level metrics are reported as a single total per chain, so theCHAIN_* family carries dimension_type: TOTAL and isn’t split further. Each metric’s cuts array in GET /supported-metrics/ lists the dimensions it supports.
The plain DAU, TXNS and NEW_USERS metrics list both TOTAL and CATEGORY cuts, and CATEGORY does resolve for DAU and TXNS:
DAU by category on 2026-08-01, top ten of twenty:
Unlike the chain splits on Lending and Stablecoins, this one isn’t a clean partition. All twenty categories sum to 605,380, well above the undifferentiated
DAU total of 439,738 for the same day, because an address active in more than one category (for example a stablecoin transfer routed through a bridge) is counted in each. Treat the category split as directional, not additive.
Each metric’s cuts array lists the dimensions it supports, and a live call confirms a breakdown’s shape before you build on it.
