Arcade Supports EMA
Arcade has added support for Ethereum Attestation Service (EAS) and Email Messaging Attestation (EMA), enabling developers to create and verify attestations with email verification. The integration allows email-based identity proofs on-chain using EAS infrastructure.
Background
Arcade is a platform that lets developers authenticate users via OAuth (a standard for granting apps limited access to accounts without sharing passwords). The Engine Manufacturers Association (EMA) is a trade group representing companies like Cummins, Caterpillar, and John Deere. This announcement means Arcade now supports EMA's OAuth 2.0 endpoints, enabling third-party apps to securely connect to these manufacturers' systems for tasks like telematics, diagnostics, and fleet management. For the broader tech-reader: EMA is adopting the same auth standards used by consumer tech (Google, GitHub), but for the heavy machinery and diesel-engine world — a sector that has historically relied on proprietary, non-standard access methods. This matters because it signals a shift toward open, interoperable authentication in industrial IoT, making it easier for developers to build tools for agriculture, construction, and logistics.
