Effectiveness · benchmark pending
We haven't benchmarked HOL Standards SDK yet, so its score is provisional — computed from safety, maintenance, and documentation only, with popularity given no weight. When we benchmark it, we measure whether it produces materially better output than a frontier model alone, and that result leads the score. How we measure.
About HOL Standards SDK
Description · AI-summarised from the hashgraph-online README
HOL Standards SDK is a production-ready TypeScript/JavaScript library that implements Hashgraph Consensus Standards (HCS-1, HCS-2, HCS-10, HCS-11, HCS-20, HCS-27) for AI agents. It provides a Registry Broker client for agent/skill discovery and verification, DNS-based domain proof verification, HCS-10 peer-to-peer encrypted communication between agents, and ledger authentication via Hedera or EVM-based systems. The SDK includes interactive CLI, runnable demos (registry broker flows, agent communication, inscriptions), and optional integrations with x402 micropayments, viem for EVM, and Hedera SDK for ledger operations.
