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.
Hedera also hasSDKs for Java, Python, Rust, Go, and Swift!
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: Build an AI agent or multi-agent system that executes at least one payment, token transfer, or financial operation on Hedera Testnet. Use one or more of the following: Hedera Agent Kit (JS/TS or Python), OpenClaw ACP, x402, A2A protocol, or Hedera SDKs directly. Provide source code in a public GitHub repo with a README covering setup, architecture, and how the payment flow works. Include a ≤ 5-minute demo video showing the agent performing autonomous payment actions.
Optional enhancements (extra points): 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
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.
Ideas to get you started: Tokenized Fund Shares — Create a fund token with KYC-gated transfers and automated dividend distributions via custom fees. Invoice Factoring — Tokenize invoices as HTS tokens, allow buyers to purchase them at a discount, and settle on maturity via Scheduled Transactions. Carbon Credit Registry — Mint carbon credits as HTS tokens with provenance tracked on HCS and retirement enforced by burning. Fractionalized Real Estate — Tokenize property ownership with royalty fees that distribute rental income to holders on every transfer. Commodity Receipts — Issue warehouse receipts as HTS tokens backed by oracle-verified commodity prices.
Qualification Requirements: Create, manage, or interact with tokens using the Hedera Token Service (via SDK, system contracts, or both). Deploy and demonstrate on Hedera Testnet. Provide source code in a public GitHub repo. Smart contracts verified on Hashscan if applicable. 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
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.
Ideas to get you started: Timestamped Proof System — Use HCS to create verifiable timestamps for documents, media, or events. Mint an HTS token as a receipt for each proof. Token-Gated Access — Mint HTS tokens that grant access to a service, event, or community. Check balances via Mirror Node to authorize users. Scheduled Payment Bot — Automate recurring HBAR or token payments using Scheduled Transactions. Build a simple UI to configure payment schedules. Supply Chain Tracker — Log product journey events to HCS and issue HTS tokens as certificates at each checkpoint. Verifiable Messaging — Build a chat or notification system where all messages are logged to HCS for tamper-proof, auditable history.
Qualification Requirements: Use the Hedera JavaScript/TypeScript SDK (@hashgraph/sdk) or Python SDK. No Solidity smart contracts. Incorporate at least two native Hedera services (e.g., HTS + HCS, HTS + Scheduled Transactions, HCS + Mirror Node). Provide source code in a public GitHub repo with a README covering setup and usage. 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)
Build a production-ready automation platform that lets users schedule, approve, and execute on-chain actions using the Hedera Schedule Service, with no bots, keepers, or off-chain cron infrastructure. Most chains lean on centralized keepers or off-chain schedulers to fire future transactions. Hedera makes scheduling a native primitive: submit a transaction, collect the signatures it needs, and let the network execute it when the conditions are met.
This bounty is focused on real-world automation workflows: payroll for contributors, treasury actions gated by governance approval, recurring subscription payments, or time-locked protocol upgrades. Think in terms of users and workflows, not just transactions. The strongest projects will feel like something a DAO, finance team, protocol operator, or business could adopt tomorrow.
Ideas to get you started: Contributor Payroll Governance-Gated Treasury Subscription Manager Time-Locked Upgrades Conditional Escrow
Qualification Requirements: Use the Hedera Schedule Service (via SDK, system contracts, or both) to create and execute scheduled transactions on Hedera Testnet. Expose a user-facing workflow to create, approve, and manage scheduled actions. Execute at least one real future or conditional transaction end to end. Provide source code in a public GitHub repo with a README covering setup, architecture, and how the scheduling flow works. Include a ≤ 5-minute demo video showing a user creating a scheduled action and the network executing it.
Optional enhancements (extra points): Approval flows: multi-sig, DAO voting, or role-based signoff before execution Conditional execution logic that combines time, on-chain state, and approvals Composable automation: scheduled calls into EVM smart contracts via system contracts A dashboard or UI to create schedules, inspect pending executions, and track execution history A clear cost, reliability, and trust comparison against off-chain bots or keepers Verifiable execution audit trails using the Hedera Consensus Service (HCS)
