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.

Prizes

🤖 AI, Agents & Hedera Services$3,500
🥇
1st place
$2,000
🥈
2nd place
$1,500
Build innovative applications, agents, tooling, or infrastructure that combine AI/ML (including LLMs and autonomous agents) with Hedera network services. The focus is on demonstrating novel AI‑blockchain integrations that create real utility for developers or end‑users.

Qualification Requirements

A submission must: Hedera Deployment – Deploy Web3 components on Hedera Mainnet, Testnet, or Previewnet and utilise at least one Hedera service: Smart Contracts (EVM), Token Service, Consensus Service, Scheduled Transactions, or Mirror Node. AI Integration – Incorporate AI in a material way — e.g. LLMs, machine‑learning models, or multi‑agent systems. Open Source – Provide all source code in public GitHub repo(s) and verify any smart contracts on Hashscan. Demo Video – Include a demo video (≤ 5 minutes) explaining what was built and how to run it. Optional enhancements earn extra points: Using multiple Hedera services. Leveraging the Hedera Agent Kit or contributing new plugins/tooling for frameworks such as Eliza, LangGraph etc. Judging Criteria Innovation – originality of the idea Feasibility – technical viability Execution – completeness & code quality Integration – depth of Hedera usage Validation – market/user potential Impact – contribution to Hedera metrics (accounts, TPS, etc.) Pitch – clarity and persuasiveness of presentation

2nd place
$1,500
Build and deploy innovative EVM‑based applications on Hedera, leveraging the Hedera Smart Contracts Service alongside key ecosystem tooling such as Chainlink, Chainlink CCIP, Pyth, LayerZero, HashPort, or HTS system contracts. Extra credit is given for incorporating additional Hedera native services.

Qualification Requirements

A submission must: Hedera Deployment – Deploy smart contracts on Hedera Mainnet, Testnet, or Previewnet using the Hedera Smart Contracts Service (EVM). Integration – Integrate at least one of the following: Oracles (Chainlink, Pyth, Supra, etc.) Bridges (LayerZero, HashPort, Chainlink CCIP) HTS System Contracts for token creation/management Hedera‑native wallet flow (HashPack, Kabila, Blade, MetaMask Snap) Open Source – Provide source code in public GitHub repo(s) with contracts verified on Hashscan. Demo Video – Include a ≤ 5‑minute demo video showing functionality and setup. Optional enhancements that boost your score: Use multiple Hedera services (HTS, HCS, Scheduled Txns, Mirror Node, etc.). Employ open‑source tooling that improves the Hedera EVM developer experience. Judging Criteria Innovation – novelty of solution Feasibility – real‑world viability Execution – code quality & completeness Integration Depth – sophistication of Hedera usage Validation – user/business potential Impact – contribution to Hedera KPIs (accounts, TPS, TVL, etc.) Pitch – clarity and persuasiveness of demo
