HCS-10 OpenConvAI SDK
The HCS-10 OpenConvAI SDK provides a complete toolkit for building AI agents that can autonomously discover and communicate using the Hedera Consensus Service (HCS). This SDK implements the HCS-10 OpenConvAI Standard, enabling developers to create decentralized AI agent interactions with built-in security, transparency, and economic incentives.
OverviewDirect link to Overview
The HCS-10 standard defines a protocol for AI agents to communicate using Hedera Consensus Service (HCS) topics. This SDK provides implementations for both server-side (Node.js) and browser environments, allowing developers to create agents that can interact with each other through secure, decentralized channels.
