About
What it answers, and for whom.
Ink is the Ethereum layer 2 that Kraken built on the OP Stack, a member of the Superchain designed as a home for DeFi, with one-second blocks. This dashboard reads its blocks for daily transactions, active addresses and fees, along with what Ink pays Ethereum to post its data and state.
Two features shape its activity. Ink's paymaster lets ERC-4337 smart accounts repay gas in USDC, USDT0 or USDG while the paymaster settles in ETH, and Kraken's exchange moves customer funds on and off the chain. The dashboard counts paymaster operations from the EntryPoint contracts and measures flows between Ink and Kraken's publicly identified wallets.
A DeFi page follows swap volume and lending on the apps that run on Ink, each read from the apps' own contract events and valued with stablecoin legs and oracle prices.
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 Ink 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; the base fee is paid into a fee vault, as on every OP Stack chain.
- Paymaster operations are UserOperationEvent logs of the v0.7 and v0.8 EntryPoint contracts whose paymaster is Ink's, with the stablecoin each account repaid in from its transfer logs.
- Exchange flows are transfers between Ink addresses and Kraken wallets identified by public disclosures; transfers to unlabelled addresses are never counted as exchange flows.
- Swap and lending figures are decoded from DEX Swap events and lending market events on Ink.

Questions
Questions people ask.
What is Ink?
Ink is an Ethereum layer 2 built by Kraken on the OP Stack. It is part of the Superchain and shares its upgrades, charges gas in ETH and produces a block every second. Kraken designed it as a home for DeFi apps.
Can I pay gas on Ink with stablecoins?
Yes, through Ink's paymaster, if you use an ERC-4337 smart account. The paymaster pays the gas in ETH and bills the account in USDC, USDT0 or USDG, depending on the EntryPoint version. ETH remains Ink's gas token.
How is Ink connected to Kraken?
Kraken built Ink and lets customers move funds between its exchange and the chain. The dashboard shows transfers between Ink and Kraken's publicly identified wallets as their own flow, so exchange deposits and withdrawals are not mistaken for on-chain trading.
Does Ink burn fees?
No. As on other OP Stack chains, Ink's base fee is paid into a fee vault rather than burned, and as a Superchain member Ink pays part of its sequencer revenue to the Optimism Collective.
- Paymaster
- A contract that pays gas for a smart account and is repaid by it, on Ink in a stablecoin.
- EntryPoint
- The ERC-4337 contract that validates and runs smart account operations; each version has its own address.
- USDT0
- A cross-chain form of USDT, moved between chains by burning and minting, which Ink's paymaster accepts for gas.
