About
Hedera stands apart as a leading EVM blockchain through its distinctive developer experience. Developers of all backgrounds can leverage familiar tools like Solidity and EVM libraries or SDKs in JavaScript, Rust, Python and more to build applications. The AI Agent Kit SDK also enables you to build agentic applications easily. The blockchain network is powered by the hashgraph consensus algorithm which enables 10,000+ TPS, 3s finality, low fixed fees priced in USD, and fair ordering (no MEV).
Hedera also has SDKs for Go and Swift!
Prizes
Create one or more agents using the Hedera Agent Kit that can send and receive A2A messages and, if appropriate, settle payments via AP2 using Hedera tokens. For example, an AI travel agent might negotiate bookings with other agents and pay with stablecoins.
Qualification Requirements
-
Multi‑agent communication — implement message exchange using the A2A standard.
-
Agent Kit integration — build your agents with the Hedera Agent Kit and its adaptors.
-
Open‑source deliverables — publish code and documentation; include a demo video illustrating agents negotiating via A2A/AP2 and settling on Hedera.
Bonus points for using multiple Hedera services or advanced features like human‑in‑the‑loop modes.
The Hedera Agent Kit supports a plugin architecture that allows developers to add new tools and integrate third‑party services. This bounty rewards the most useful and well‑architected new plugin that introduces new capabilities. Plugins might wrap external APIs (e.g., DeFi protocols, data providers), simplify token operations, or provide analytics and monitoring.
Qualification Requirements
-
Follow the plugin architecture — your plugin must adhere to the Hedera Agent Kit’s plugin interface and be installable via npm or similar.
-
Provide clear documentation — include setup instructions, available tools and example usage. Explain how the plugin interacts with Hedera and any external services.
-
Demonstrate utility — build a small sample agent showing how the plugin is used. If the plugin interfaces with Hedera network services, ensure contracts are verified and transactions are signed appropriately.
-
Deliverables — publish the plugin code and example project under an open‑source licence, supply a README and a short demo video.
Bonus points for interoperability with other agent ecosystems or for integrating real‑world data sources.
Links and Resources
Hedera’s EVM compatibility allows developers to write Solidity contracts while benefiting from fast finality and low fees. This bounty is about using cross‑chain and real‑world data to build innovative dApps. Example ideas include multi‑chain financing, cross‑chain auctions or data‑driven trading bots.
Qualification Requirements
-
Deploy and verify a smart contract on Hedera — use Hedera mainnet, testnet or previewnet; verify contracts on Hashscan.
-
Integrate oracles and/or bridges — consume external price feeds from Chainlink, Pyth or Supra, and/or use Chainlink CCIP, LayerZero or HashPort for cross‑chain transfers.
-
Use Hedera services where relevant — consider HTS System Contracts or the Token Service for hybrid native/EVM functionality.
-
Deliverables — provide open‑source code, a clear README and a demo video. Bonus points for combining multiple oracles/bridges, integrating Hedera wallet flows (HashPack, Kabila, MetaMask Snap), or offering a novel real‑world use case.
