About

Hedera stands apart as a leading EVM blockchain through its distinctive developer experience, enabling developers of all backgrounds to leverage familiar tools like Solidity or its JavaScript SDK* to build breakthrough applications. Linux Foundation Decentralized Trust manages Hedera’s open-source codebase (as Project Hiero) including the hashgraph consensus algorithm which enables 10,000+ TPS, 3s finality, low fees priced in USD, and the highest grade (aBFT) of security. Meanwhile, the Hedera public network is governed by a diverse council of the world’s leading institutions to ensure transparent and fair decision-making. By empowering the development of applications that solve real-world challenges across DeFi, tokenization, AI, digital identity, and more, Hedera is the trust layer that underpins a decentralized future.

The Hedera whitepaper can be found at www.hedera.com/papers. *Hedera also hasSDKs for Java, Python, Rust, Go, and Swift!

Prizes

🤖 Best Use of Hedera Agent Kit & Google A2A ⸺ $4,000
🥇
1st place
$3,000
🥈
2nd place
$1,000
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

1. Multi‑agent communication — implement message exchange using the A2A standard. 2. Agent Kit integration — build your agents with the Hedera Agent Kit and its adaptors. 3. 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.

🎨 Best Hedera x Lit Protocol Vincent Skill ⸺ $1,000
🥇
1st place
$1,000
🥈
2nd place
$0
This challenge asks builders to create a Vincent “skill” that uses Hedera services and Lit Protocol’s Vincent framework. Vincent provides secure agent identity, verifiable capability delegation and secure action execution via Lit’s threshold cryptography. The skill should use Hedera services such as EVM smart contracts, the Token Service or Consensus Service. Examples include automated staking strategies, token swaps or delegated payments.

Qualification Requirements

1. Use at least one Hedera service — EVM Smart Contracts, Token Service, Consensus Service, Scheduled Transactions, or the Hedera Agent Kit. Smart contracts must be verified on Hashscan. 2. Integrate Vincent — register your agent/app, define tools and capabilities, and use the Vincent SDK. 3. Deliverables — open‑source code in a public repo, a README explaining architecture and dependencies, and a demo video (≤ 5 minutes) showing how a user delegates permissions and the skill executes actions. Bonus points for using multiple Hedera services or cross‑chain integrations.

🔌 Best Plug‑In for Hedera Agent Kit ⸺ $1,000
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

1. Follow the plugin architecture — your plugin must adhere to the Hedera Agent Kit’s plugin interface and be installable via npm or similar. 2. Provide clear documentation — include setup instructions, available tools and example usage. Explain how the plugin interacts with Hedera and any external services. 3. 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. 4. 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.

🔗 EVM Innovator Track ⸺ $4,000
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

1. Deploy and verify a smart contract on Hedera — use Hedera mainnet, testnet or previewnet; verify contracts on Hashscan. 2. 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. 3. Use Hedera services where relevant — consider HTS System Contracts or the Token Service for hybrid native/EVM functionality. 4. 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.
