Advancing the did:ethr Method Specification
An RFP to modernize and advance the did:ethr method specification, a lightweight decentralized identifier (DID) system widely used across Ethereum and EVM-compatible networks. The did:ethr method leverages ERC-1056 smart contracts to provide an onchain identity layer readable by both smart contracts and external systems. While it has become a core part of Ethereum’s identity landscape, the current specification and reference implementations are outdated and no longer fully aligned with the latest W3C DID Core and Decentralized Identity Foundation (DIF) standards. This RFP seeks proposals to update the specification, improve conformance and interoperability across chains, modernize tooling and libraries, and guide the method through the DIF “Recommended” process. The project will also include documenting real-world deployments, addressing known implementation issues, and re-establishing the did:ethr method as a maintained public good through renewed community engagement with the Ethereum and identity ecosystems. Full background, scope, deliverables, and evaluation criteria are available in the complete RFP document linked in Resources.

Ecosystem Need
The did:ethr method has seen broad organic adoption but now lacks an up-to-date specification, consistent test coverage, and clear interoperability guidance. These gaps reduce compatibility with other DID methods and complicate integration across modern EVM and L2 systems. As decentralized identity becomes increasingly important for verifiable credentials, ZK-proof integrations, and cross-chain authentication, Ethereum needs a current, well-documented, and verifiable identity standard. This RFP funds targeted updates, testing, and standardization work to bring did:ethr to full maturity.
Hard Requirements
- Analyze the current did:ethr specification and identify gaps with W3C DID Core v1.0 and DIF requirements. - Update and modernize the specification, ensuring alignment with current EVM and L2 environments. - Improve reference resolver and registry libraries, addressing outstanding issues and adding test coverage. - Document existing deployments and in-the-wild usage across EVM networks. - Guide the specification through the DIF “Recommended” process and facilitate community review.
Soft Requirements
- Open-source release under a permissive license. - Clear documentation and examples for developers and integrators. - Collaboration with DIF and relevant Ethereum identity working groups. - Engagement with existing identity and credential projects in the ecosystem. - Commitment to handoff or continued maintenance after project completion.
