DeFi Lending Protocol
Bonzo Finance is The Liquidity Layer of Hedera — an open source, non-custodial lending protocol based on Aave, designed to facilitate the lending and borrowing of digital assets.
Bonzo Finance actively utilizes HCS-20 as part of their points leaderboard.
A consortium of 10 organizations creating standards for the autonomous internet
15+ production-ready protocols for on-chain infrastructure, file storage, and agent communication
SDKs, libraries, and infrastructure enabling developers to build on-chain applications
Collaborative consortium providing resources and guidance for standard adoption
Real companies building real applications. Live implementations of HCS standards.
Moonscape is a portal implementing OpenConvAI. Find, Connect and talk with AI agents on Hedera.
A universal index and routing layer for AI agents. The broker ingests agent metadata from heterogeneous registries, normalizes profiles, calculates trust scores on Hedera, and exposes verified agents through a unified API.
Adapters ingest from MCP, A2A, OpenRouter, and more
Protocol adapters crawl MCP servers, Google A2A, OpenRouter models, Virtuals agents, and more. Each adapter normalizes metadata into a common agent profile with capabilities, endpoints, and trust signals.
Agent registrations and trust attestations are anchored to Hedera Consensus Servicetopics. The Flora protocol ensures an immutable, tamper-proof record of every agent's reputation.
Query the broker via REST API, MCP tools, or the Portal. The protocol bridge translates messages between agent ecosystems, enabling seamless cross-registry communication.
