Overview
3xpl is a free website for looking up what happened on a blockchain: a payment, a block, or an address's history. Paste in an address or transaction code and you get a plain readout of what is attached to it. It covers dozens of networks and lays each out identically, so what you learn on one carries over.
Cardano and Bitcoin each get their own 3xpl pages, alongside the rest of the networks it indexes. The project was built by former staff of Blockchair, a multi-chain explorer, and its About page frames the difference in the same terms: one shared data format for every chain, and no advertising1. Its Cardano explorer is listed in the Essential Cardano directory maintained by Input Output Group2.
Key Features
- One search box for many chains. Look up an address or transaction on Cardano, Bitcoin, and dozens of other networks without switching sites, and read every result in the same layout3.
- Printable receipts and statements. 3xpl turns a single transaction into a PDF receipt, or an address's history into a wallet statement laid out like a paper bank statement, useful for accounting or tax paperwork1.
- No ads, and reachable over Tor. 3xpl states its pages carry no advertising, and the site is also reachable over Tor, the network people use to browse without revealing who they are3.
- Free data for students and academics. Researchers can ask for no-cost access to the same downloadable datasets and query tools that paying customers use4.
- Open code you can check yourself. 3xpl publishes the core software that reads each blockchain, so anyone can run it against their own copy of a network and confirm the numbers match what the site displays5.
What to Expect
A casual visitor gets the simple version: a search box, a row of chains showing their latest indexed blocks, and a page for each address, block, and transaction. The Cardano side covers two kinds of activity: ordinary ADA transfers and native token transfers6. A separate name lookup resolves $ada handles, the readable nicknames people attach to Cardano addresses4.
Developers and analysts get a second layer. 3xpl hands out the underlying data several ways: bulk files you can load into your own database, a connection layer (an API) that returns results as structured text, a live feed that pushes new blocks and address activity as they land, and direct database access for anyone who wants to write their own queries4. A public trial version of the connection layer works with no key at all7. Credentials are handed out through the project's Discord server4.
Because every chain is squeezed into one shared format, 3xpl states that it does not process chain-specific data1. Cardano machinery such as staking, governance, and smart contract internals sits outside what it models. A Cardano-only explorer will go further on those. The trade 3xpl makes is breadth and consistency across many chains rather than depth on any one; single-chain block explorers sit at the other end of that trade.
