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 fees
Transactions, active addresses and fees on Era, with paymaster use and refunds.
Active addresses, latest day
countDistinct accounts that sent at least one transaction on ZKsync Era on the latest complete UTC day.
Paid by paymasters
%The share of transactions on the latest complete day whose fee was paid by a paymaster contract rather than the sender.
Median fee after refund
USDThe median fee per transaction on the latest complete day, after the refund of unused gas.
Transactions and active addresses by day
countDaily transactions and daily active addresses on ZKsync Era over the selected period.
Fees charged and refunded by day
ETHETH charged up front each day, split into what was kept as fees and what was refunded, with paymaster-paid fees shown apart.
Batches on Ethereum
How long Era's batches take to be committed, proven and executed.
Commit to execution, median
hoursThe median time from a batch's commitment on Ethereum to its execution, over the selected period.
Pubdata cost, latest day
ETHWhat Era paid Ethereum on the latest complete day to publish its batches' state changes, in blob or calldata fees.
Time per step by day
hoursDaily median time from commitment to proof and from proof to execution, for batches settled that day.
Latest batches
The most recent batches with their Era block range, transactions, pubdata bytes and the Ethereum transactions that committed, proved and executed each one.

About
What it answers, and for whom.
ZKsync Era is the zk rollup built by Matter Labs and governed through ZK Nation, the holders of the ZK token. It runs EraVM, its own virtual machine, which Solidity and Vyper contracts are compiled for, and every account on it is a smart account. This dashboard follows Era's daily transactions, active addresses and fees, read from its blocks.
Two things set its fees apart. A paymaster contract can pay a transaction's fee for the sender, as a sponsor or in exchange for another token, and unused gas is refunded once a transaction has run. Era also publishes the storage changes of each batch to Ethereum rather than every transaction, so a fee depends on the state a transaction writes. The dashboard measures paymaster use, refunds and the cost of that data.
Batches move through three steps on Ethereum: committed, proven and executed. The dashboard times each step from the settlement contracts, since execution decides when a withdrawal to Ethereum can be finalized.
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 ZKsync Era blocks; priority transactions sent from Ethereum are counted apart from those sent on Era.
- Fees are what accounts finally paid: the ETH transferred to the bootloader for each transaction minus the refund it returned, both read from the transaction's logs.
- A transaction is paymaster-paid when the fee transfer to the bootloader comes from a paymaster contract instead of the sender; paymasters are labelled where their operator is public.
- Batch timing is read from the commit, proof verification and execution events of each batch in Era's settlement contracts, matched to the Era blocks inside it.
- Pubdata cost is what Era paid to publish each batch's state changes to Ethereum, from the blob and calldata fees of its commit transactions.

Questions
Questions people ask.
What is a paymaster on ZKsync?
A paymaster is a contract that pays a transaction's fee for the sender, either as a sponsor or in exchange for another token. Because accounts on Era are smart accounts by default, any app can offer this without extra infrastructure. The dashboard shows the share of transactions paid this way each day.
Why does ZKsync refund gas?
Era charges a transaction for its gas limit up front and refunds what was not used once it has run, so the amount charged can be well above the amount finally paid. The dashboard reports fees after refunds, which is what users actually spent.
How long do ZKsync Era withdrawals take?
A withdrawal can be finalized on Ethereum once the batch that contains it has been executed there, which follows its commitment and the verification of its proof. The dashboard times those steps for every batch, and the withdrawal times dashboard compares Era with other rollups.
What is the ZK token used for?
ZK is the governance token of ZK Nation, which votes on upgrades to ZKsync's contracts and on token programs. Proposals since late 2025 aim to tie the token to network revenue; the dashboard shows a buyback or burn only once it appears on-chain.
What is pubdata?
Pubdata is the data Era publishes to Ethereum so its state can be rebuilt: the storage slots each batch changed, compressed, rather than every transaction. A transaction that writes many new storage slots costs more in pubdata than one that only reads.
- Native account abstraction
- Smart account features built into the protocol, so every account can set its own signature rules and have its fees paid by a paymaster.
- Paymaster
- A contract that pays transaction fees on behalf of users, as a sponsor or in exchange for another token.
- Pubdata
- The state changes a ZKsync batch publishes to Ethereum so anyone can rebuild the chain's state.
- Bootloader
- The system program that runs every Era block: it validates transactions, charges fees and returns refunds.
