# Base Monthly Report: Activity, Fees, Costs and Apps > A monthly Base report: transactions, active addresses, fees users paid, what Base paid Ethereum, stablecoins, DEX volume and token launches, each one cited. Markdown copy of https://voltfincrypto.com/apps/base-monthly-report **Question:** How much was Base used this month, what did it earn against what it paid Ethereum and which apps drove it? - Kind: Report in Voltfin Folio - Topic: [Layer 2s](https://voltfincrypto.com/topics/layer-2) - Chains: Base, Ethereum - Status: Planned. The data is not published yet, so this page states no figure; each figure will open its receipt when it is. Base is the Ethereum layer 2 incubated by Coinbase, and much of its activity follows what Coinbase users and Base apps do in a given month: stablecoin payments, DEX trading, token launches and smart wallet use. This report records each month in one dated edition, with every figure read from Base and Ethereum and pinned to a block. Each edition covers usage, what users paid in fees, what Base paid Ethereum to post its data, the margin between the two and where activity came from: the apps, contracts and tokens that grew or shrank. Base announced in 2026 that it would move from the OP Stack to its own codebase, and the report notes protocol changes in the month they take effect. ## Blueprint ### Base this month in brief The month's main changes in usage, fees, costs and apps, and what drove each of them. Cites: Transactions; Active addresses; Fees users paid. ### Usage Transactions, active and new addresses, smart account operations and the contracts that used the most gas. Cites: New addresses; Smart account operations; Top contracts by gas. ### Fees, costs and margin What users paid in execution and data fees, what Base paid Ethereum in blob and gas fees and the margin between them. Cites: Paid to Ethereum; Margin; Median fee per transaction. ### Stablecoins and DEX trading Stablecoin supply and transfers on Base, DEX volume by protocol and the pairs that traded the most. Cites: Stablecoin supply; DEX volume; Top pairs. ### Apps and launches The apps that grew or shrank most, token launches and graduations and the new contracts deployed. Cites: Tokens launched; Contracts deployed; Fastest-growing apps. ### What changed on the network Upgrades, parameter changes and incidents in the month, with the blocks at which they took effect. ## How it will be measured - Activity counts transactions and the addresses that sent them in each UTC day of the month, from every Base block, with smart account operations counted once each. - Fees users paid are the execution and data fees recorded in each transaction receipt, checked against the inflows to Base's fee vault contracts. - What Base paid Ethereum is the gas and blob fees of the batch transactions its batcher sent to Ethereum, plus any state root or proof transactions, in the same month. - App activity groups transactions by labelled contracts. Stablecoin supply is each token's supply at the month's last block, and DEX volume comes from decoded Swap events. ## Data it needs - `l2_activity_daily` (to build): Per layer 2 per day: transactions, active addresses, fees users paid on the L2, and what the L2 paid Ethereum to settle and post data. - `blob_usage_daily` (to build): EIP-4844 blobs posted per day, blob gas used, blob base fee, and the rollup that posted them. - `stablecoin_supply_daily` (published): Native supply of each USD and EUR stablecoin on each covered chain at the chain's last block of each day, from totalSupply() reads, with bridged copies kept apart. - `dex_swaps_daily` (to build): Swap counts and volume per DEX, pool and chain per day, decoded from Swap events, valued with stablecoin legs and oracle prices. - `token_launches_daily` (to build): New tokens deployed per chain and launchpad per day, how many reached a DEX pool, and how many were abandoned. - `address_labels` (to build): Labels for known addresses: exchanges, bridges, protocols, funds, treasuries, sanctioned addresses and known attackers. - Source: Every Base block in the month: transactions, senders, gas used and receipt fees - Source: Inflows to Base's fee vault contracts - Source: Batch and blob transactions from Base's batcher to Ethereum, with their gas and blob fees - Source: totalSupply() of stablecoins on Base at the month's last block - Source: Swap events and launchpad factory events on Base ## Questions ### How does Base make money? Users pay fees on Base for execution and for the cost of posting data to Ethereum. The sequencer, run by Coinbase, collects them, and the difference between what users pay and what Base pays Ethereum is its margin. The report measures both sides each month. ### Does Base share revenue with Optimism? Under a 2023 agreement, Base shared part of its sequencer revenue with the Optimism Collective. In 2026 Base said it would move off the OP Stack to its own codebase, and Optimism said the revenue share would not continue. The report records the payments it can see on-chain. ### Why are fees on Base low? Base posts its transaction data to Ethereum in blobs, which have a fee market of their own and usually cost far less than calldata. Its execution fee rises only when its blocks fill up. The report shows both parts of the fee and how each moved through the month. ### How is this different from the Base chain stats dashboard? The dashboard shows Base day by day, as it happens. This report is a dated monthly edition: it sums the month, compares it with the last and explains what changed, with every figure cited to the blocks it was read at. ### Which apps drive Base activity? It changes from month to month. Stablecoin transfers, DEX trading, token launchpads and social and creator apps have each led at different times. The report ranks contracts and apps by transactions, gas used and fees each month. ## Glossary - **Sequencer**: The operator that orders transactions on a layer 2 and produces its blocks; on Base it is run by Coinbase. - **Batcher**: The address that posts a layer 2's transaction data to Ethereum, usually in blobs. - **Flashblocks**: Partial blocks that Base streams every 200 milliseconds ahead of each full block, so apps can show a transaction's result sooner. ## Related apps - [Base Chain Stats: Transactions, Users and Fees](https://voltfincrypto.com/apps/base-chain-stats) - [Stablecoins on Base: Supply and Transfers](https://voltfincrypto.com/apps/stablecoins-on-base) - [L2 Profitability: Fees Earned vs Costs Paid to Ethereum](https://voltfincrypto.com/apps/l2-profitability) - [Base Token Launches: Zora Coins and Clanker Tokens per Day](https://voltfincrypto.com/apps/base-token-launches-zora-clanker) - [Top Ethereum L2s: Monthly League Table of Rollups](https://voltfincrypto.com/apps/top-ethereum-l2s-monthly) - [Ethereum TPS: Mainnet and Layer 2 Transactions per Second](https://voltfincrypto.com/apps/ethereum-tps) Build it in Voltfin Studio: https://app.voltfincrypto.com/signup?next=%2F
