hashgraph-online/standards-sdk
The official Hashgraph Online Standards SDK, implementing the standards found in https://hol.org/docs/standards
Provides modular implementations for HCS standards including agent communication (HCS-10), decentralized identity (HCS-11), and file storage (HCS-1/3), with optional transport adapters for Hedera ledger authentication, EVM chains via Viem, and X402 credit payments. The Registry Broker client enables skill verification through DNS TXT proofs and UAID discovery, while HCS-10 demos showcase trustless peer-to-peer messaging with automatic state resumption on interruption.
