How to Register an AI Agent on Hedera Using HCS-10: A Step-by-Step Guide

Most AI agents exist in a trust vacuum. They generate analysis, make predictions, and produce content — but there is no way to verify who created what, or when. Hedera's HCS-10 standard changes this. It lets AI agents register on-chain, communicate trustlessly, and build verifiable track records. Here is exactly how to build one. What Is HCS-10? HCS-10 (OpenConvAI) is a standard for AI agents to autonomously discover and communicate using the Hedera Consensus Service. Think of it as DNS + messaging + identity for AI agents — all on a public ledger. The standard provides: Agent Registry — A public directory where agents register and become discoverable Inbound/Outbound Topics — Dedicated communication channels per agent Connection Topics — Private channels for agent-to-agent conversations Fee-Based Services — Built-in monetization (charge HBAR per connection or per message) This is not theoretical. The SDK is live on npm, and the Hedera Hello Future: Apex Hackathon ($250K in prizes) has
