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

🤖 AI & Agentic Payments on Hedera ⸺ $6,000
Up to 2 teams will receive $3,000
Build AI agents that move value autonomously on Hedera. The agentic economy needs payment infrastructure that works at machine speed: sub-second finality, predictable sub-cent fees, and native token operations without smart contract overhead. Hedera is built for this. Use the Hedera Agent Kit, OpenClaw's Agent Commerce Protocol, the x402 payment standard, or any combination of agentic tooling to build agents that discover services, negotiate terms, and settle payments on Hedera. Whether it's micropayment streaming, agent-to-agent commerce, or autonomous DeFi, the best projects will demonstrate real payment flows between agents or between agents and services.

Qualification Requirements

1. Build an AI agent or multi-agent system that executes at least one payment, token transfer, or financial operation on Hedera Testnet. 2. Use one or more of the following: Hedera Agent Kit (JS/TS or Python), OpenClaw ACP, x402, A2A protocol, or Hedera SDKs directly. 3. Provide source code in a public GitHub repo with a README covering setup, architecture, and how the payment flow works. 4. Include a ≤ 5-minute demo video showing the agent performing autonomous payment actions. Optional enhancements: - Multi-agent payment negotiation and settlement using A2A or OpenClaw ACP - Implementation of x402 for pay-per-request API or service access - On-chain agent identity using ERC-8004 or HCS-14 (Universal Agent IDs via Hedera Consensus Service) - Agent discovery and communication via UCP (Universal Commerce Protocol) - Token creation, custom fee schedules, or royalty flows via the Hedera Token Service (HTS) - Scheduled or recurring payments using Hedera Scheduled Transactions - Verifiable payment audit trails using Hedera Consensus Service (HCS) - Use of the Hedera CLI for agent workflow automation

🪙 Tokenization on Hedera ⸺ $2,500
Up to 2 teams will receive $1,250
Build a tokenization application using the Hedera Token Service (HTS). Hedera's native token service lets you create, configure, and manage tokens at the protocol level with built-in compliance controls, custom fee schedules, and atomic operations, no smart contract required. This bounty is focused on real-world asset tokenization: securities, real estate fractions, invoices, carbon credits, commodities, fund shares, or any asset class where on-chain representation unlocks liquidity, transparency, or automation. Projects that demonstrate a clear path from physical asset to on-chain token with meaningful compliance or lifecycle management will be favoured.

Qualification Requirements

Qualification Requirements: 1. Create, manage, or interact with tokens using the Hedera Token Service (via SDK, system contracts, or both). 2. Deploy and demonstrate on Hedera Testnet. 3. Provide source code in a public GitHub repo. Smart contracts verified on Hashscan if applicable. 4. Include a ≤ 5-minute demo video showing token creation, configuration, and at least one lifecycle operation (transfer, compliance check, fee distribution, etc.). Optional enhancements (extra points): - Use the @hiero-ledger/hiero-contracts NPM package for HTS system contract imports - Implement compliance controls: KYC grants, account freezing, or token pause - Custom fee schedules (fixed fees, fractional fees, royalty fees on transfers) - Cross-chain token operations using LayerZero, CCIP, or HashPort - Oracle integration (Chainlink, Pyth, Supra) for asset pricing or external data - Scheduled token operations (vesting, distributions) using Hedera Scheduled Transactions

🛠️ "No Solidity Allowed" — Build with Hedera SDKs ⸺ $3,000
Up to 3 teams will receive $1,000
Build a working application on Hedera using only the Hedera SDK. No Solidity, no smart contracts. Use native Hedera services directly: create tokens, post messages to the Consensus Service, schedule transactions, manage accounts, or combine multiple services into something new. This bounty is designed for developers who are new to Hedera or new to blockchain. Hedera's SDK lets you do things that typically require smart contracts on other chains: create fungible and non-fungible tokens, set up custom fee schedules, schedule future transactions, and publish verifiable messages, all with a few lines of JavaScript or Python.

Qualification Requirements

Qualification Requirements: 1. Use the Hedera JavaScript/TypeScript SDK (@hashgraph/sdk) or Python SDK. No Solidity smart contracts. 2. Incorporate at least two native Hedera services (e.g., HTS + HCS, HTS + Scheduled Transactions, HCS + Mirror Node). 3. Provide source code in a public GitHub repo with a README covering setup and usage. 4. Include a ≤ 5-minute demo video showing the application in action. Optional enhancements (extra points): - Coherent end-to-end user experience (not just API calls) - Integration with the Hedera Mirror Node REST API for querying network data - Creative use of Hedera Consensus Service for data integrity, logging, or messaging - Use of the Hedera Agent Kit for AI-driven workflows (counts as SDK usage) - Thoughtful security approach (key management, access controls) Ideas to get you started: - Timestamped Proof System - Token-Gated Access - Scheduled Payment Bot - Supply Chain Tracker - Verifiable Messaging
