What the dashboard will show.
The dashboard as it will open in Vantage. Each figure is named here and arrives with its receipt; until its data is published, its place stays empty.
Activity and gas
Transactions, active addresses and gas on Unichain.
Active addresses, latest day
countDistinct addresses that sent at least one transaction on Unichain on the latest complete UTC day.
Base fee now
gweiThe base fee per gas of the latest Unichain block, from its header.
Median transaction fee
USDThe median fee paid per transaction on Unichain on the latest complete day, including the L1 data fee.
Transactions and active addresses by day
countDaily transactions and daily active addresses on Unichain over the selected period.
Trading and fees
Uniswap swaps on Unichain and the sequencer revenue sent toward the UNI burn.
Swap volume, latest day
USDUniswap swap volume on Unichain on the latest complete day, across v2, v3 and v4 pools.
Swaps' share of gas
%The share of gas used on Unichain on the latest complete day by transactions that swapped on Uniswap.
Swap volume by Uniswap version
USDDaily swap volume on Unichain split by Uniswap v2, v3 and v4.
Sequencer revenue sent to the TokenJar
ETHUnichain sequencer revenue that reached the TokenJar each month since UNIfication, from the transfers that carried it.

About
What it answers, and for whom.
Unichain is the OP Stack layer 2 that Uniswap Labs launched in February 2025, a Superchain member with one-second blocks and 200-millisecond preconfirmations streamed between them as flashblocks. This dashboard follows its daily transactions, active addresses and gas, read from Unichain's blocks.
Much of Unichain's activity is trading, so the dashboard also measures swap volume on Uniswap's pools there by version, along with the share of the chain's gas that swaps use. Under the UNIfication proposal passed in December 2025, Unichain's sequencer revenue is routed to the TokenJar, the contract that releases Uniswap's protocol fees to whoever burns UNI.
Every figure names the Unichain or Ethereum block it was read at, so sequencer revenue sent toward the burn can be traced from the fee vaults to the TokenJar, transfer by transfer.
Method
How it will be measured.
Every figure will be read at a block, kept with its source and its exact read, and open a receipt anyone can re-check.
How receipts work →- Transactions and active addresses are counted per UTC day from Unichain blocks, leaving out the L1 attributes deposit that opens each block.
- Fees are gas used times effective gas price plus the L1 data fee and operator fee from receipts; as on other OP Stack chains, the base fee is paid into a fee vault rather than burned.
- Swap volume is decoded from Uniswap v2, v3 and v4 Swap events on Unichain and valued with stablecoin legs and oracle prices; v4 volume is split by hook where a pool has one.
- Sequencer revenue sent to the burn is read from fee vault withdrawals and the transfers that reach the TokenJar, matched to the period the fees were collected in.

Questions
Questions people ask.
What is Unichain's block time?
Unichain produces a block every second, and its sequencer streams 200-millisecond preconfirmations, called flashblocks, within each block. Flashblocks are an extension outside the core protocol: the one-second blocks are what settle to Ethereum.
Is Unichain part of the Superchain?
Yes. Unichain is built on the OP Stack, shares the Superchain's upgrades and pays the Superchain revenue share to the Optimism Collective. It runs permissionless fault proofs, so anyone can challenge an incorrect state claim.
Where do Unichain's fees go?
Fees collect in the chain's fee vaults. Under UNIfication, Unichain's sequencer revenue is sent to the TokenJar, which releases it to whoever burns UNI in the Firepit contract. The Uniswap fee switch dashboard follows the burn itself.
How much of Unichain's activity is trading?
The dashboard measures it each day: swaps as a share of transactions and of gas used, plus swap volume on Uniswap's pools by version. Bots trade heavily on fast chains, so the share is shown with the number of distinct addresses that swapped.
- Flashblock
- A preconfirmation of part of the next block, streamed by Unichain's sequencer between full blocks.
- TokenJar
- The contract that collects Uniswap protocol fees and Unichain sequencer revenue until someone burns UNI to release them.
- Fee vault
- A predeploy contract on an OP Stack chain that collects one kind of fee until it is withdrawn.
