The Bear Necessities Hackathon by Moonbeam & AWS encourages building with core Web3 infrastructure. It offers a fun, competitive, and rewarding environment to explore Moonbeam's interoperable features and create cross-chain connected applications.

This hackathon is supported by teams building critical Web3 infrastructure, that provide core functions for developers to launch applications on Moonbeam. Check the full list of sponsors below!

Moonbeam Foundation

Moonbeam Foundation Logo

The Moonbeam Foundation promotes the development, growth, and adoption of Moonbeam and its ecosystem.

Moonbeam is a smart contract platform enabling cross-chain connected applications to access users, assets, and services on any chain. It unites Ethereum, Cosmos, Polkadot, and more, solving fragmented user experiences and unlocking interoperability. Moonbeam's platform uses integrated cross-chain messaging, allowing developers to create smart contracts that access services across remote blockchains. With a developer-friendly EVM platform, extensive tool support, and modern Substrate architecture, Moonbeam is ideal for building connected applications.

Amazon Web Services (AWS)

enter image description here

Amazon Web Services (AWS) is the world’s most comprehensive and broadly adopted cloud, offering over 200 fully featured services from data centers globally. Millions of customers—including the fastest-growing startups, largest enterprises, and leading government agencies—are using AWS to lower costs, become more agile, and innovate faster.

Chainlink (Hackathon Oracle Provider)

Chainlink Logo

Chainlink is the industry-standard Web3 services platform that has enabled trillions of dollars in transaction volume across DeFi, insurance, gaming, NFTs, and other major industries. As the leading decentralized oracle network, Chainlink enables developers to build feature-rich Web3 applications with seamless access to real-world data and off-chain computation across any blockchain and provides global enterprises with a universal gateway to all blockchains.

StellaSwap (Hackathon LaunchPad Provider)

StellaSwap Logo

StellaSwap is one of the first automated market-making (AMM), decentralized exchange (DEX) for the Moonbeam Network. The unique value proposition of StellaSwap is that they are committed to establishing a strong foundation with their native token, STELLA, as a governance token, diverse farms, a built in bridge and user-centered service.

StellaSwap's main objective is to create a broader range of network effects to address the issues of liquidity in the DeFi space, instead of limiting to a single solution like many DEXs are doing now. This manifests itself in the diverse product suite of StellaSwap that will be explained in more details. StellaSwap products are structured in such a way that facilitates decentralized governance of STELLA holders, while continuing to innovate on the collective foundations by design.


Subquery Logo

SubQuery is an open source blockchain data indexer for developers that provides fast, flexible, reliable, and decentralised APIs to power leading multi-chain apps. Our goal is to save developers' time and money by eliminating the need of building their own indexing solution. Now, they can fully focus on developing their applications. SubQuery helps developers create the decentralised products of the future.

SubQuery also provides free, production grade hosting of projects for developers. Our Managed Service removes the responsibility of managing infrastructure, so that developers do what they do best — build. Find out more here.

The SubQuery Network allows developers to completely decentralise their infrastructure stack. It is the most open, performant, reliable, and scalable data service for dApps. The SubQuery Network indexes and services data to the global community in an incentivised and verifiable way. After publishing your project to the SubQuery Network, anyone can index and host it - providing data to users around the world faster and reliably.


Biconomy Logo

Biconomy is a Web3 developer and transaction infrastructure platform that simplifies UX and accelerates mass Web3 adoption. Their decentralized UX stack offers powerful tools to developers for removing complexities, onboarding users, and scaling dApps. Biconomy launched a hyper-flexible SDK in Nov 2022, enabling developers to integrate with their non-custodial, multi-chain, and gas-efficient relayer infrastructure easily. The SDK provides benefits like one-click user journeys, transaction bundling, and gas fee control, enhancing UX and onboarding for end users.

Seamless UX and onboarding for end users become a reality when dApps and enterprises leverage the benefits of BiconomySDK including:

  • ✅Simplified UX + User Onboarding
  • ✅Secure and Easy Self-Custody
  • ✅Gasless Transactions
  • ✅One-Click, Chainless Experiences
  • ✅Transaction Batching
  • ✅Customisable and composable modules, like Legos

Main Prizes
Moonbeam Foundation Grand Prizes (2)
USD 7500

The Moonbeam Foundation is dedicated to promoting the development, growth, and adoption of Moonbeam and its ecosystem. With these prizes, the foundation would like to recognize projects that stand to make significant contributions to the Moonbeam ecosystem. The Moonbeam Foundation Grand Prizes are awarded to projects that excel in all 4 categories of judging criteria:

  • Technical Excellence
  • User Experience
  • Value proposition
  • Creativity

There are no additional requirements for this bounty.

Best Use of a Moonbeam Precompile
USD 5000

Moonbeam has a variety of precompiles (solidity interfaces) that offer powerful features yet are easy to use. As a few examples:

  • The Batch Precompile allows you to combine multiple transactions such as an approval + a swap transaction into a single atomic call.
  • The Call Permit precompile enables a user to sign a message approving any EVM call which can then be dispatched via Biconomy.
  • Additionally, Moonbeam has a number of precompiles that expose Substrate functionality such as Democracy, Staking, and more.
  • Use any Moonbeam Precompile in an non-trivial way to qualify for this bounty. If multiple qualifying submissions are received, the highest scoring qualifying project as determined by the judges will be awarded the prize. A full list of Moonbeam Precompiles is available here.
Connect the World with Chainlink (5)
USD 2000

Build something awesome using Chainlink! Anything that came from the Chainlink Documentation counts, such as using Price Feeds, VRF, or Automation.

  • Chainlink Automation enables conditional execution of your smart contracts functions. Define the business rules, the trigger and what will happen.
  • Chainlink VRF is the verifiable, tamper-proof random number generator for blockchain gaming and NFT projects. Any smart contract can get random values without compromising security or usability.
  • Chainlink Proof of Reserve Feeds provides the status of the reserves for several assets in the same way as Price Feeds.
  • Chainlink NFT Floor Pricing Feeds provides a conservative and risk averse floor price estimate for an NFT collection.
  • Chainlink Data Feeds are the quickest way to connect your smart contracts to the real-world data such as asset prices, reserve balances, and L2 sequencer health.

To be eligible, the project should make use of Chainlink to make a state change on the blockchain to be eligible. It can be any Chainlink services. Nice to have: how you use Chainlink in the project description. It must be possible for the judges to find the Chainlink use in your code. Only the intention to use is not valid. You must present your project for the Chainlink judges! Projects whose team does not present will not be evaluated.

We will look at the following criteria:

  • UI/UX/DX - How useful is your application? Is it visually appealing?
  • Blockchain technology application - How valuable this project is for decentralization and adoption of Blockchain and Web3
  • Wow Factor - Anything not covered above! This is if you blow us away in some other way.
