Overview
Cexplorer is a Cardano blockchain explorer that provides tools for browsing on-chain data including blocks, transactions, stake pools, native assets, and governance activity. Built and maintained by Vellum Labs s.r.o., the platform serves as a comprehensive data interface for the Cardano network, offering both visual exploration tools and programmatic API access for developers1.
Originally launched as ADApools.org during the Cardano Incentivized Testnet era, Cexplorer is one of the longest-running blockchain explorer services in the Cardano ecosystem. The platform underwent a full rebrand and architectural overhaul, transitioning from its original stake-pool-focused scope to a broad blockchain explorer covering all on-chain activity. The open-source TypeScript frontend reflects an ongoing commitment to transparency and community-driven development2. Cexplorer has received funding through Project Catalyst, Cardano's community innovation fund, supporting continued feature development and infrastructure improvements.
Cexplorer positions itself as a general-purpose Cardano explorer with particular depth in stake pool analytics and governance participation tools. It caters to delegators evaluating pools, developers integrating on-chain data, and community members tracking governance proposals and DRep activity.
Key Features
- Stake pool directory and analytics. A searchable list of all registered Cardano stake pools with performance metrics including rewards history, luck percentage, pledge amounts, fee structures, and top delegator breakdowns. The pool list supports a proprietary ranking system that weighs multiple performance factors beyond raw stake size1.
- Governance hub. A dedicated governance section surfaces DRep profiles, voting records, governance actions, Constitutional Committee membership, power threshold visualizations, and the full text of the Cardano constitution3. Users can follow proposal progress and delegate their stake to DReps directly.
- Developer API. A tiered API offering with a free Starter plan providing 300 requests per day, alongside NFT-gated and custom PRO tiers for higher-volume integrations4. Full API documentation is hosted on a separate documentation portal.
- Network-wide data browser. Browsable views for blocks, epochs, transactions, addresses, native assets, datums, and smart contracts, providing a unified interface for all Cardano on-chain activity.
- Educational content and bot integrations. A regularly maintained article section covers Cardano protocol updates, staking mechanics, and ecosystem developments. Telegram and Discord bot integrations enable automated notifications for pool performance and network events.
What to Expect
The Cexplorer interface loads quickly and presents data in dense, sortable tables suited to users who prefer detailed numerical information over simplified dashboards. Navigation is organized around primary data categories -- pools, blocks, transactions, assets, and governance -- with each section offering both list views and dedicated analytics tabs. Localized versions of the site are available in Japanese and Czech, broadening accessibility beyond English-speaking audiences. The platform supports both mainnet and testnet environments, making it a practical tool for developers testing applications against live network data. A bug bounty program encourages responsible security disclosure, and community members can suggest features or report issues through the project's public GitHub repository2.
