Overview
AdaStat is a free website for looking up activity on a blockchain: a payment, the wallet it came from, the block it landed in, or a token someone minted. Paste an address, a transaction ID, or a pool name into the search box and the record comes back. It also keeps full pool and account history, not just today's snapshot1.
The blockchain in question is Cardano, and AdaStat is an independent project, built by members of the Russian-speaking Cardano community1 as an alternative to the explorers the network's own developers publish2. The project says it has no financial revenue beyond the stake pool its team operates, and asks visitors who want to support it to delegate ADA to that pool1; its open-source rebuild was separately funded by a Project Catalyst grant3. Lead developer Dmitry Stashenko describes the site as carrying no third-party advertising, no user trackers and no analytics2.
Key Features
- History, not just the latest state. Pool and account pages carry active epochs (the fixed time periods Cardano runs on), blocks produced, staking and rewards over time, so a delegator can compare pools on track record and an operator can study their own1.
- One place for the whole chain. Blocks, transactions, accounts, addresses, epochs, tokens, and community polls each get their own browsable section, alongside the pool and account pages1.
- Governance data beside the chain data. Proposals, voting history, and statistics on DReps (the delegated representatives who vote on Cardano governance for other people) sit in the same explorer as blocks and transactions, which is why Essential Cardano lists AdaStat among Cardano's governance tools4.
- A free API with no sign-up. The public interface that lets other software pull AdaStat's data needs no key or account, covers epochs, blocks, transactions, pools, accounts, addresses, and tokens, and offers its data under the Apache 2.0 licence5.
- Code you can read or run yourself. Both halves of the explorer, the site and the service feeding it data, are published on GitHub under Apache-2.0, with the Preprod and Preview test networks supported alongside Cardano's main network6.
What to Expect
You land on AdaStat's dashboard summarising the live state of the network, with a single search box above it. Tabs lead off to blocks, transactions, pools, accounts, epochs, tokens, DReps, governance actions, and polls1, and a favourites list holds the pools, tokens, and accounts you mark with the heart icon7.
The pool pages are built for two readers: ADA holders comparing pools on created blocks and reward history before choosing where to delegate, and pool operators analysing their own pool alongside others to shape a strategy1. Developers can skip the interface and pull the records straight from the API instead5.
The live interface runs in English, German, Russian, and Ukrainian, and balances can be converted into a long list of fiat currencies1. The open-source rebuild of the explorer was funded through Project Catalyst, the grant programme Cardano ADA holders vote on3. AdaPulse's project review credits the explorer to a Cardano stake pool operator with a web-development background8.
