24 Etherscan Features in 2024

2024 was a transformative year for Ethereum L2s, with significant advancements in infrastructure and tooling that accelerated deployments, increased TPS, and kept user fees low.

Amid the rapid rise of L2s, Team Etherscan focused on unifying the user and developer experiences in an increasingly multichain ecosystem, while continuing to support important upgrades and improvements on the Ethereum mainnet.

As we look ahead to 2025, let’s take a moment to recap on the 24 features Team Etherscan launched in 2024. How many do you recognize? Take the quiz and share which features you'd like to see us roll out this year!

  1. Explorer as a Service (EaaS)

The trend of L2s gained even more momentum in 2024, with new networks launching one after another. As part of our EaaS product, we helped build reliable and scalable L2 block explorers, including 9 EVM explorers, ZKsync, Frax, Blast, Mantle, Taiko, World, Unichain (testnet), Sophon, Abstract (testnet), and 1 SVM explorer, Eclipse.

Additionally, we developed 2 L3 explorers, Xai and Apechain, and supported 3 other L1 explorers, including Solana, XDC, and Sonic.

  1. Blockscan Multichain Explorer (Beta)

Full explorers like Etherscan can often be overwhelming for everyday users. To address this, we released Blockscan (Beta) as a follow-up to the Multichain Portfolio feature. Blockscan provides a cleaner transaction receipt and aggregated multichain portfolio, with links back to the respective full explorers for more detailed information.

This simple explorer is also available on the redesigned Blockscan mobile app alongside the convenient chat functionality.

  1. Cards

On May 1st, we introduced Cards, enabling trusted third-party integrations to display additional useful information related to addresses and tokens.

In 2024, we integrated a total of 13 Cards, including airdrop claimables, POAP collection, token security detection, attestations, yield opportunity, DAO activity, supply analysis, unique humanity score, builder score, safety score, EAS attestations, token smell test, and Tap 2 Grow (a week-long tap-to-earn game with a Devcon twist).

  1. Blobs

In March, core developers deployed the Dencun upgrade to mainnet, introducing blobs—temporary data storage that is significantly cheaper for L2 settlement.

Blob data has been available on Etherscan since day one and remains accessible even after regular beacon nodes remove it, typically after 18 days of storage.

  1. Etherscan API V2: Multichain (Beta)

As EVM chains gain greater adoption and applications become easier to deploy across multiple chains, the use of APIs from various EVM explorers developed by Team Etherscan has also increased. Previously, developers had to manage multiple API keys and subscriptions from different explorers to query similar endpoints.

The introduction of the Multichain API streamlined this process, enabling developers to manage a single Etherscan subscription and query endpoints from over 50 EVM chains with a single API key by specifying the chain ID.

Developers can also verify the same contract on multiple chains at one-go.

  1. Account Abstraction Transactions (Beta)

The traditional onboarding process for Ethereum via EOAs can be cumbersome, particularly for retail users. They are often given a 12-word seed phrase and expected to self-custody their assets, risking permanent fund loss if the phrase is forgotten.

Account abstraction (AA) simplifies this by shifting from EOAs to smart contract wallets. This enables features like multisig approvals, social recovery, sponsored gas fees, and bundling multiple actions (user operations) into a single transaction. And these AA transactions can now be viewed directly on the explorer!

  1. Input Data Decoder

If you're a frequent Etherscan user and want to analyze the function breakdowns and parameters of input data in a transaction, you can now use the new tool to decode and interpret data sent to Ethereum smart contracts.

  1. Diamond Proxy Support (Beta)

Diamond Proxy contracts enable partial upgrades, allowing developers to add, replace, or remove specific functionalities while keeping other parts intact.

In response to a long-overdue feature request, developers can now easily view all facet contracts associated with a diamond proxy.

  1. Experimental Feature: Transaction Action

We’ve introduced a new setting that allows you to enable experimental features and explore Etherscan in new ways by trying out features before they’re rolled out to all users.

  1. Stylus Contract Verification & API

In September, Arbitrum launched Stylus on mainnet, enabling developers to write smart contracts in languages other than Solidity, such as Rust, that compile to WebAssembly (WASM).

Smart contracts written in Stylus and deployed on Arbitrum One and Arbitrum Nova can now be verified on the respective explorers.

We also enabled Stylus contract verification via API. You can find the documentation here.

  1. More Domain Name Support
  • You can now search for DNS names imported into ENS on the explorer.
  • Besides, ENS names forward lookup is now available on all L2 explorers, simply go to your favorite L2 explorer and search for your ENS name.
  1. MEV-Protected Transactions Searchable while Pending

As private transactions rose in 2024 to shield against MEV-hungry bots, searching for these pending transactions on Etherscan was not possible, as they were not available in the public mempool. Since then, we've integrated MEV-protected transactions with several leading providers, making them searchable on Etherscan while pending.

  1. Extended NatSpec Support

NatSpec (Ethereum Natural Specification Format) is a standard for documenting smart contracts in Ethereum. It makes contracts easier to understand for users, developers, and tools like wallets or IDEs.

We've extended NatSpec support to include interface & abstract contracts, similar match contracts, and parameter description for tuples.

  1. Gas Tracker Decimal Points

During a time when Ethereum gas prices dropped below 1 gwei, we added 3 decimal points to the gas tracker for improved accuracy.

  1. Code Reader Update

When we first released the Code Reader in 2023, users needed an OpenAI API key to use it. In August, we integrated the Groq AI model as a third option, allowing anyone logged into an Etherscan account to use Code Reader for free.

  1. Token & Method Highlight

In addition to address highlight, which helps distinguish between genuine and poisoned addresses, we’ve also applied this functionality to tokens and methods, making it easier to differentiate between similarly named tokens with different contract addresses and methods with different IDs.

  1. Converter Tools

Our handy set of converter tools is a Swiss Army knife for data conversion, allowing you to switch between various data types directly on the explorer.

  1. Private Name Tag Groups

Private name tags can be grouped for improved organization and easier tracking.

  1. Custom Error for Proxy Contracts

Previously, smart contract transactions with custom errors only displayed "Fail" when the transaction reverted. Now, custom errors are shown, making it easier for developers to debug and understand what caused the transaction revert.

  1. Search Results Page

This feature is particularly useful when searching for a specific token or address without knowing the exact term. Simply press "Enter" to view a list of results and use filters to narrow it down to show only tokens or addresses.

  1. Additional Safeguards on Certain Token Transfers

Transfers of tokens on the Custom Ignore list or those with a poor reputation are hidden across Etherscan by default, but they can be unhidden in the settings.

We’ve also added a popup reminder to double-check when copying tokens involved in low-value transfers to help avoid falling victim to dust attacks.

  1. Advanced Filter Presets (Beta)

We added presets for quick access to complex filters involving swaps and bridges done via protocols without having to manually adjust filter settings each time.

  1. Token Standard Checker

See which standard a token adheres to, and let us know if there are any other standards you'd like us to include in the checker!

  1. And More Quality-of-Life Updates ✨

  • Entity icons before addresses – making it easier to distinguish them from the sea of addresses

As we step into 2025, Team Etherscan remains dedicated to supporting the Ethereum ecosystem with powerful tools and features that empower users, developers, and the broader community.

Thank you for being part of this journey with us—your feedback helps us shape a better, more seamless experience for everyone. Here’s to another great year ahead in 2025! ✨
