ENS Metadata Standard

Project Overview At BlocLabs LLC, we are spearheading the development of the ENS Metadata Standard, a proposed EIP that aims to make smart contracts more discoverable and transparent across Ethereum Virtual Machine (EVM) networks. This project is focused on creating a standardized method to tag and organize smart contract metadata, allowing contracts to be easily indexed and searched within the Ethereum Name Service (ENS) and other ecosystems.

Why Are We Doing This?

As decentralized applications (dApps) and smart contracts proliferate across various blockchains, the need for discoverability and searchability has grown. Currently, there’s a gap in the Ethereum ecosystem regarding how contract metadata is handled and surfaced to users, developers, and other services.

BlocLabs saw an opportunity to address this by working on a standardized metadata format that can:

  • Enhance Discoverability: By standardizing the way metadata is defined and attached to smart contracts, users and developers can easily search and filter contracts based on specific criteria (e.g., function type, asset class, creator identity).

  • Promote Transparency: With a standardized way to display contract metadata, end users can access clear and relevant information about the contracts they interact with, building trust in decentralized applications.

  • Enable Indexing Across Chains: A metadata standard will allow smart contracts to be indexed across multiple EVM-compatible chains, creating a more interconnected ecosystem.

Benefits to BlocLabs and the Community

For BlocLabs

  • Leadership in Innovation: By leading the development of this standard, BlocLabs strengthens its position as a thought leader in blockchain development and smart contract innovation. This project aligns with our vision of enhancing blockchain usability and transparency.

  • Internal Application: As BlocLabs continues to build decentralized applications and smart contracts for clients, having a standardized metadata format will streamline our own development processes, making our contracts easier to manage and deploy.

  • New Service Opportunities: By contributing to the open-source community and pioneering this standard, BlocLabs can offer additional services, such as contract indexing and metadata management, to our enterprise clients.

For the Ethereum and Blockchain Community

  • Searchable Contracts: The ENS Metadata Standard will allow for smarter contract searching, benefiting both developers looking for existing contracts to build on and users seeking to interact with specific functionalities.

  • Cross-Platform Compatibility: This standard isn't limited to Ethereum—it will be applicable across all EVM-compatible chains, fostering greater interoperability.

  • Enhanced User Trust: Transparent metadata can provide users with a better understanding of what contracts do before interacting with them, reducing the risk of interacting with malicious or unverified contracts.

What’s Next?

As we move forward, BlocLabs is working on:

  • Community Involvement: Engaging with the Ethereum developer community to gather feedback, suggestions, and potential improvements to the standard.

  • EIP Submission: Finalizing the draft of the ENS Metadata Standard and submitting it to the Ethereum Improvement Proposal (EIP) repository for formal review and adoption.

  • Testing and Deployment: Implementing and testing the standard within our own projects, while encouraging adoption from other developers and platforms.


The ENS Metadata Standard is more than just a technical upgrade—it’s a step toward making smart contracts more user-friendly, discoverable, and transparent. By setting a precedent for how metadata is handled in the decentralized space, BlocLabs is driving forward the future of blockchain usability.
