Infra provides an open‑source attestation infrastructure that lets developers and agents cryptographically sign structured data, creating verifiable records that others can trust and build upon. Leveraging the Ethereum Attestation Service SDK, the platform enables on‑chain attestations with features like revocability, expiration control, and schema definitions, facilitating reliable data provenance for applications ranging from AI evaluation results to broader decentralized workflows.

Problem
Developers and autonomous agents need a reliable way to create cryptographically signed, structured data that can be independently verified and referenced by other applications, but existing solutions often require proprietary APIs, complex integrations, or lack support for revocable and never‑expiring schemas.
Solution
Infra offers an open‑source attestation infrastructure that lets developers and agents sign structured data and publish it either on‑chain or in a private store. The platform provides a free SDK (e.g., @ethereum-attestation-service/eas-sdk) and a command‑palette interface for registering schemas, creating attestations, and managing revocation without any API keys. Attestations are immutable, optionally revocable, and can be set to never expire, enabling flexible trust models. Because the data is cryptographically signed, any downstream application can verify its authenticity on demand, facilitating composable workflows across decentralized and traditional systems. Infra’s tooling abstracts the underlying blockchain interactions, allowing teams to integrate attestation capabilities in hours rather than weeks.
Target Audience
Primary users are blockchain developers, AI/ML model evaluators, and autonomous agents that need to publish verifiable results or metadata for downstream consumption.
Features
- Open‑source SDK for JavaScript/TypeScript that supports on‑chain and off‑chain attestation workflows
- Command‑palette UI for schema registration, attestation creation, and revocation without writing code
- Support for revocable and never‑expiring schemas, giving developers fine‑grained control over data lifecycle
- Zero‑API‑key requirement; all operations run against public blockchain nodes or local stores
- Compatibility with Ethereum‑compatible chains via the Ethereum Attestation Service standard
- Built‑in data decoding utilities for common types (strings, integers, bytes32) to simplify verification
