AI & Agentic Payments on Hedera

$6,000

$2,000 × 3 winners

H Accrue$2,000
H Kickoff Aivy Studio$2,000
H Mars$2,000

Prize details

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.

Qualifications

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

"No Solidity Allowed" — Build with Hedera SDKs

$3,000

$1,000 × 3 winners

Prize details

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.

Qualifications

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)

Autonomous On-Chain Automation Platform

$3,000Existing project

$1,000 × 3 winners

Prize details

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

Qualifications

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)

Tokenization on Hedera

$3,000

$1,500 × 2 winners

H cashmeifyoucan$1,500
H Wafer$1,500

Prize details

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.

Qualifications

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

Best Private Nanopayments

$1,000

A Manila$1,000

Prize details

# This is a collaborative bounty between Dynamic, Arc, and Unlink. Machines are starting to pay each other (for API calls, inference, data, and compute) in amounts far too small for traditional rails. But today those payment streams are fully transparent: anyone can watch an agent's spend, infer its strategy, and map its counterparties. Build a system where autonomous agents (or users) make high-frequency, low-value payments that are also private. How the pieces fit together: - Dynamic embedded/server wallets give your agents (or users) a wallet and sign the offchain payment authorizations — no seed phrase, no popup per payment. - Arc + Circle Gateway provide the gas-free, stablecoin-native nanopayment rail (USDC via x402 / batched settlement) where sub-cent payments make economic sense. - Unlink wraps the flow so balances, transfer amounts, and counterparty history stay confidential

Qualifications

Use all three: the project must integrate Dynamic, Arc (testnet), and Unlink as core components - Dynamic: use Dynamic wallets to onboard the user/agent and sign payment authorizations. Embedded wallets for user-driven flows; server wallets (with delegated access) are the fit for autonomous agents signing - Arc: settle nanopayments on Arc testnet using USDC via Circle Gateway (x402 / batched settlement). Demonstrate real gas-free micro-settlement, not a single large transfer. - Unlink: integrate the Unlink SDK (@unlink-xyz/sdk) so at least one payment is genuinely private; the demo must show a real private transfer or withdrawal. - Your app must be deployed and usable by judges - Working demo (live or short video). - Public GitHub repo + README explaining how each of the three integrations is used and what specifically is private.

Best product integrating Walrus for storage

$6,000Existing project

$3,000 × 2 winners

S Azimuth$3,000
S bitrouter$3,000

Prize details

We're looking for the most market-viable products and dApps already relying on decentralized storage that choose Walrus as their storage solution for this hackathon. Bring an app real users would actually reach for, and put Walrus underneath it — media, user data, app assets, or whatever your product stores today. We care more about depth than breadth here: the strongest submissions will show a clear product, real traction or a credible path to it, and Walrus doing genuine work in the stack rather than a quick add-on bolted on to qualify. Walrus is chain-agnostic, so it slots in regardless of where your app already lives — including EVM. If you're currently on IPFS, Arweave, Filecoin, or an S3 bucket, this is a great weekend to give Walrus a try.

Qualifications

- The project must read from and/or write to Walrus (testnet or mainnet) as a core part of the app. - The project must be an existing product (not built from scratch this weekend) that is adopting Walrus during the hackathon. - A working demo of the Walrus integration must be submitted.

Best new build with Walrus & the Sui stack

$3,000

S Proof of Scan$3,000

Prize details

For teams starting something new this weekend. We'd love to see products that tap into Sui and any part of its stack — Walrus for decentralized storage, DeepBook for on-chain liquidity and order books, and everything else Sui offers. For EVM developers, Walrus is the most natural entry point: it's the chain-agnostic piece that drops straight into an EVM app, so you don't need to build entirely on Sui to take part — but if your idea reaches deeper into the stack, even better. Just like the existing-products track, we're looking for the most market-viable products — real ideas people would actually use — with Walrus or the broader Sui stack doing genuine work: storing blobs behind a smart contract, hosting a frontend, replacing IPNS, anchoring a DAO proposal or a verifiable manifest, powering an NFT drop, building on DeepBook, or wherever it fits your concept.

Qualifications

- The project must be newly developed during the hackathon. - The project must make meaningful use of Walrus and/or the Sui stack (not a superficial add-on). - A working demo must be submitted.

C Canary$2,000
C OpenPop$2,000
C Vouch DeFi$2,000

Prize details

*Build your first workflow with CRE!* Chainlink Runtime Environment (CRE) is an all-in-one orchestration layer that enables developers to build institutional-grade smart contracts — data-connected, compliance-ready, privacy-preserving, and interoperable across blockchains and traditional systems. With CRE, you can connect blockchains to external APIs, enterprise systems, data sources, LLMs, or AI agents. Using the CRE SDK (available in Go and TypeScript), you’ll build Workflows — modular programs that orchestrate logic across on-chain and off-chain environments. With the CRE CLI, you can compile, simulate, and deploy these workflows to CRE, where they run on a Decentralized Oracle Network (DON) for fault-tolerant execution.

Qualifications

📍*Requirements:* ✅ *Goal:* Build, simulate, or deploy a CRE Workflow that’s used as an orchestration layer within your project. ✅ *Your workflow should:* - Integrate at least one blockchain with an external API, system, data source, LLM, or AI agent. - Demonstrate a successful simulation (via the CRE CLI) or a live deployment on the CRE network. - Be meaningfully used in your project 💡 If you show us a successfully simulated workflow execution, our team will deploy it to the live CRE network for you during the hackathon! You do NOT need to deploy it during the hackathon, simulation is fine!

Prize details

Build AI agents and AI-powered products that use Ledger as the trust layer. We are looking for projects where device-backed security is central to the product: agents that pay for tools and services, systems that authenticate themselves with Ledger-secured identity, human-in-the-loop workflows for sensitive actions, and products that make autonomous behavior safer instead of bypassing user intent. **EXAMPLE DIRECTIONS** * Agents that pay for APIs, tools, or services with Ledger-secured payment flows, including x402-style patterns. * Create human-in-the-loop agents where Ledger approves high-risk actions before funds move or permissions escalate. * Ledger-backed identity, authentication, credentials, or policy-based spending for autonomous systems. * Build AI copilots that explain transactions, simulate outcomes, or surface risks in complex flows. * Developer agents that help teams integrate Ledger SDKs, generate Clear Signing artifacts, or validate implementation flows. * Vertical products such as treasury agents, commerce assistants, or enterprise copilots where Ledger is the explicit control layer. **WHAT WE LIKE** * Real user value, not generic chatbot wrappers. * Clear boundaries between autonomous behavior and explicit approval. * Concrete use of Ledger primitives, not just wallet branding. * Practical demos that show why device-backed trust matters for AI.

Qualifications

**WHAT TO INCLUDE** - Feedback on overall experience using Ledger docs & SDKs - Identify gaps, confusing flows, or missing context - Specific improvements with screenshots or PRs

Best Unlink Integration into a Major Open-Source App

$2,500

U Lunave$2,500

Prize details

Take a real, widely-used open-source app and give it privacy. Unlink is an embedded privacy SDK (deposit(), transfer(), withdraw(), execute()`), so you can route an existing product's flows through private balances without rebuilding it. A working "private [well-known app]" is the kind of demo that we want to see. **Suggested targets** (or pick any reputable OSS app): - **Wallets** — MetaMask Snap, Rabby, Rainbow: add privacy to an existing wallet - **DeFi** — Uniswap, Aave, Euler: route swaps or supply/borrow through a private account via execute() - **Treasury** — Safe, Sablier, Superfluid: private payouts, streams, or treasury moves Judged on how cleanly Unlink slots into the app, the privacy it adds, and how close the result is to something a company can deploy immediately.

Qualifications

- Start from a real, widely-used open-source app (a suggested target or a comparable reputable project) and integrate the Unlink SDK (`@unlink-xyz/sdk`) during the event. - Integrate at the **interface / SDK / module layer** — wire the app's existing flows through Unlink. You do not need to redeploy the underlying protocol. - Working demo showing the app's flow now running privately, plus a short video. - Public repo + README linking the upstream project and explaining exactly what you added and what is now private.

Best use of Unlink SDK for Payments

$1,500

U Manila$1,500

Prize details

Already building something? Continue it here and make it private. This track is for teams extending their own existing project by adding Unlink, so the work you arrive with counts and the privacy layer is what you ship this weekend. Good fits: a payouts tool, stablecoin or wallet app, treasury system, DeFi product, AI agent wallet, trade settlement flow, or grants and rewards platform you've already started, now with private balances, confidential transfers, or private DeFi via execute(). Judged on how naturally privacy fits the existing product, UX, and usefulness.

Qualifications

- Extend a project your team already started before the event (your own prior work) by integrating the Unlink SDK (@unlink-xyz/sdk). This is the Continuity track, so the base project must be genuinely yours. - Add at least one private primitive: deposit(), transfer(), withdraw(), or execute(). - Demo must show your existing project's flow now running with Unlink privacy. - Public repo + README that shows the project's pre-event state (commit history or release) and explains exactly what privacy you added this weekend.
