Hedera is a leading EVM blockchain through its distinctive developer experience, enabling developers of all backgrounds to leverage familiar tools like Solidity or JavaScript SDK.
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.

Optional enhancements (extra points):
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.

Build an automation platform that uses Hedera as the decentralized hub for multi-chain automation — scheduling and triggering smart contract calls on other chains, fully on-chain, with no bots, keepers, or off-chain cron. Combine the Hedera Schedule Service with Axelar General Message Passing (GMP) so a scheduled transaction on Hedera fires when its conditions and signatures are met, then dispatches a message through Axelar that executes a contract call on a destination chain. Most chains rely on centralized keepers for automation — Hedera flips it: scheduling is a native primitive, Axelar GMP handles decentralized message passing, and together they enable trustless cross-chain automation.
Focus on real-world workflows: cross-chain payroll, treasury rebalancing, recurring DCA into assets on another chain, scheduled liquidity actions, or time-locked governance execution. The strongest projects will feel production-ready — something a DAO, finance team, or protocol could adopt immediately — and will prove the entire trigger-to-execution loop happens on-chain, with zero centralized servers.

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.

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.
