3000 Chains

Blockscout newsletter August 2025

Did you know that Blockscout open-source explorer is used by more than 3000 blockchains! This ecosystem-wide support gives us a unique vantage point where we can provide statistical analysis and insights about many different ecosystems.

We use several tools to track Blockscout deployments, and find that the numbers fluctuate often. Some chains are ephemeral or short-lived testnets, and others are purely experimental projects. However, the majority of the deployments we see are chains meant to last, serving users based on a particular use-case or niche (ie gaming chains, intellectual-property chains, social interaction chains, supply chain tracking chains, stable chains etc etc etc). Blockscout supports them all!

In a recent blog post, we wrote a high-level overview related to the larger ecosystems we serve like Ethereum, Optimism, Arbitrum, Base, and Gnosis.

Analytics and statistics overview of popular blockchains
Compare leading blockchains through onchain stats. This Blockscout-powered guide highlights real metrics across Ethereum, Base, Optimism, Ink, Soneium, Unichain and more.

In future posts we plan to explore additional chains using Blockscout to find unique insights about user behavior, use-case adoption, and overall chain metrics. For now, you can explore basic chain info for Blockscout-supported chains using the Chainscout Raycast extension.


Our latest Merits campaign on XRPL is nearly done (ends 24 August)! Earn Merits and badges for bridging, interacting, and GM'ing on this rapidly growing EVM sidechain.

๐Ÿชฟ Ethereum GEAS contracts

The recent Pectra hard fork added several important system contracts to Ethereum. Normally, developers can verify that contracts work as intended by checking them in the explorer. However, these particular contracts were written in a specialized programming language called GEAS (the Good Ethereum Assembler), and most current verification tools and explorers don't support it.

At Blockscout, we felt it was important to show the code for these predeploys and expose the underlying methods, so we decided to verify these contracts ourselves! Learn more about GEAS, how we leveraged our Ethereum Bytecode DB, and explore the predeploy contracts in this blog post๐Ÿ‘‡๐Ÿป.

Verifying Ethereum Predeploy Contracts
Contract verification is a vital service block explorers provide to blockchains. Through the verification process, the underlying code becomes human-readable, enabling anyone to check contract code and interact with the read and write methods within the contract. Typically, smart contracts are deployed to a blockchain by an external user at

๐Ÿ’› Exploring Celo L2

Celo is thriving since their transition to an L2 rollup in March of this year. With 1-second blocks, sub-cent transactions and security from the Ethereum base layer, Celo has seen rapid growth in the past few months, like quadrupled DEX volume since May.

Blockscout has provided an explorer for the Celo ecosystem for years, including before, during, and after the migration process. We're proud to be a day one partner with their latest Celo Sepolia testnet, which will replace the Alfajores and Baklava testnets in September.

In addition, we recently rolled out epoch support for Celo. Epochs are generated once per day and used as a schedule for distributing validator rewards, voting rewards, community funds, and carbon offsets. You can view distribution amounts, validator set participants for each epoch on the Celo explorer.

๐ŸŒŠ XRPL campaign wrapping

Last call for the XRPL Merits campaign! XRP has had a huge year and the XRPL sidechain gives you an opportunity to explore this ecosystem in EVM-compatible ways. Bridge assets and explore today! Details about the campaign are in the post below - it ends Aug 24 with badges available starting Aug 27.

๐Ÿค New Integrations

This week we celebrate several integrations helping spread Blockscout to new frontiers.

  • Raycast provides an ecosystem of extensions and an AI integration, giving users an interface for managing different workflows and finding info fast. The Chainscout extension gives you instant access to chain information for 100s of Blockscout supported chains.

  • The SmitheryAI platform helps developers create, manage, and use MCP servers. Easily add the Blockscout MCP to your AI workflow to access advanced info on tokens, contracts, dapps and much more. Blockscout was selected as a featured app this week, and has already seen nearly 5K monthly tool calls from developers.

๐Ÿš€ Autoscout is growing

The Autoscout self-launch platform continues to grow! We've seen hundreds of chain deployments, from indie devs launching a brand new testnet to large projects needing immediate explorer support.

Autoscout is convenient, quick, and allows you to spin up an instance for any length of time. You only pay for the bandwidth you use. Input a few variables, buy credits with crypto (or fiat), and launch in minutes.

To learn more, read our case study with Gas.zip, a project using Autoscout to launch instances and find and fund bridge contracts in record time.

If you are interested in taking Autoscout for a test drive, visit the Autoscout channel in Discord and we'd be happy to get you going with some free credits.


The Blockscout newsletter goes out to all MyAccount  community users on supported chains. We welcome your feedback on topics you'd like to see covered or any questions you have. Visit us on X or Discord to get your explorer questions answered or get your project added to our growing network list.
