Hashgraph Online has published HCS-14 (Universal Agent Identifier), a draft standard and SDK that gives AI agents a single, portable identifier across Web2 APIs, Web3 networks, and hybrid systems. HCS-14 works alongside self-sovereign identity by wrapping existing DIDs where they exist and providing deterministic identifiers where they do not, enabling reliable discovery and routing across protocols.

Status: Draft. We welcome feedback from the community at https://github.com/hashgraph-online/hcs-improvement-proposals/discussions/135.

HCS‑14 is network‑agnostic. It works across Web2 (A2A/REST), EVM/ETH, and more. Hedera support is optional. We start with Web2 and EVM, then cover Hedera.

TL;DR​

• A single, portable identifier (UAID) for agents across Web2 and Web3
• Two modes: deterministic AID or wrap your existing DID
• Minimal routing hints for discovery; identity details stay in DID docs/profiles

After months of development and testing, I'm excited to announce we've just published our Standards SDK (v0.0.44) to npm. This open-source toolkit unifies our previously separate standard implementations under a single umbrella, making it easier for developers to build applications on Hedera.
