About

The HOL Standards SDK provides reference implementations of Hashgraph Consensus Standards (HCS), maintained by HOL. Its RegistryBrokerClient covers skill verification, skill lifecycle status and UAID DNS TXT verification, and a smaller rb-client package is published separately. Optional peers cover X402 payments, EVM and Hedera ledger authentication, and core agent search and chat need only a fetch implementation.

Use cases: crypto-web3, identity-access
