Etherscan integrates identity cards powered by Web3bio

Etherscan just made anonymous wallet addresses a little less anonymous. The block explorer has integrated Web3 identity cards powered by Web3.bio’s API, letting users see aggregated onchain identity data, including ENS names, avatars, Lens profiles, and Farcaster accounts, right on an address page without clicking away.

What the integration actually does

When you pull up an Ethereum address on Etherscan, the explorer can now display a consolidated identity card. That card aggregates publicly available onchain data from multiple identity and social protocols: ENS (Ethereum Name Service), Lens Protocol, Farcaster, and potentially others like Unstoppable Domains and SPACE ID.

The data comes from Web3.bio’s API, which indexes verifiable links across naming services and decentralized social protocols. It pulls together names, profile pictures, linked social accounts, and other identity markers into a single formatted view.

Before this, checking who was behind a wallet meant manually cross-referencing addresses across different platforms. You’d look up the ENS name on one site, check the Farcaster profile on another, and maybe try to find a Lens handle somewhere else. Now Etherscan surfaces all of that in one place.

The company behind the curtain

Web3.bio was launched by Mask Network back in August 2021, positioning itself as a comprehensive identity graph and link-in-bio service for the decentralized web. The platform indexes public records across multiple blockchains, including Ethereum and Solana, and supports a range of identity protocols including Unstoppable Domains and SPACE ID.

Mask Network itself has been building at the intersection of traditional social media and Web3 for years, developing browser extensions and tools that overlay decentralized features onto platforms like Twitter. The Web3.bio product fits neatly into that thesis: making onchain identity legible to people who don’t want to become blockchain forensics experts.

Why onchain identity is having a moment

ENS has grown to millions of active names. Lens and Farcaster are processing tens of millions of social interactions per month, according to available data. These aren’t toy networks anymore.

There’s also a privacy dimension that deserves consideration. Web3.bio indexes publicly available onchain data, meaning it’s surfacing information that users have already chosen to make visible. But aggregation changes the calculus. A single ENS name linked to a single address is one thing. A comprehensive identity card that ties together your ENS, Lens, Farcaster, and potentially other profiles in a single view makes correlation significantly easier, for better or worse.

For users who value pseudonymity, this is a reminder that onchain identity is opt-in but increasingly visible. The more protocols you link to a single address, the more complete the picture becomes for anyone who looks you up.
