1) Build a Staking Pool - Qualifiers split a $12,000 Pool.

Develop a staking pool on SSV with the core functionality of being able to stake less than the amount of ETH the staker wishes, on Ethereum.

Staking pools are usually revenue generating, allowing wallets to stake less than 32 ETH in a smart contract which pools ETH deposits together and spins up a validator.

🔗 Learn more on DVT-based staking pools | 🔗 Integration Guide

2) Build a ‘SSV as a service’ Qualifiers split a $8,000 Pool.

Develop a staking service that uses SSV as its backend. The operation should manage SSV-related barriers such as fees and payments on behalf of stakers.

The interface needs to be configured to hardcode validator operations to a specific/permissioned cluster of operators.

Polygon is offering the following:

📲 $4,000 for best social dapp with Lens Protocol - Not your keys, not your content. Lens is a user-owned social graph #onPolygon. Join Sandeep in signing Lens Protocol’s open letter and build a social dapp with Lens where your users own their content, social graph, and data.

📇 $4,000 for best use of Polygon ID - Polygon ID is a solution that provides self-sovereign, decentralized and private identity for the next iteration of the Internet. Create a product that integrates Polygon ID’s on-chain verification and permissionless attestation.

🤑 $4,000 for best local LATAM public goods or Refi project(s) - Public goods are good. Solve a problem relevant to LATAM by building either a public good or a regenerative finance app. Explain how your hack will benefit the local community and how it could scale globally.

👩🏽‍💻 $4,000 for best UX - One of the most challenging problems in Web3 is creating an intuitive and seamless User Experience for dapps. Build a dapp that raises the bar for UX in some way. Hint: check out Rahat’s EthOnline talk on UX. Within your README, explain what you’ve done to hack together a MDP (minimum delightful product).

🏊‍♀️ $4,000 prize pool - Deploy at least one smart contract on Polygon’s testnet or mainnet for a share of our prize pool.

🏆 Superfluid is offering:

• 🥇 Best Overall Project - $3000
• 💸 Best DeFi Prize - $2000
• 💡 Most Innovative Hack - $2000
• 🌠 Best NFT Hack - $2000
• 🏊 Honorable Prize Pool - $1000

🥇Top prize - $4,000 'Best use of Hyperlane' messaging API

• To win this prize you simply need to build an application that utilizes the messaging API to establish interchain connectivity. You could be passing messages or assets. You could be making cross-chain view calls or oraclize data between blockchains. There is really no end to what you could build, but given that time is of the essence you don’t want to expand scope too much.
• A great way to shoot for the top prize is to attempt to make an interchain version of a popular app, i.e. an interchain Compound or Sudoswap.

💸 Best use of Hyperlane - $2,000 - DeFi related

• As noted above there are many ways you can win our prizes, but here are some DeFi related ideas:
• You could use our Interchain Accounts API to create an app that allows for interchain swaps without having to deploy any contracts on remote chains.
• You could create an interchain Stableswap, accepting deposits of assets on multiple chains and creating unified liquidity pools.
• You could create a contract that allows you to control multiple SAFEs or DAOs on remote chains. Using Interchain Accounts you could do this without having to deploy any additional logic on the receiving chains.
• You could create interchain payment streaming contracts, collecting deposits on a number of chains and directing assets to their destinations.

🌠 Best use of Hyperlane - $2,000 - NFT related

• You could create an interchain minting contract that acts as a load balancer between chains, i.e collecting orders on several chains (with lower fees or higher throughput) and executing the mint on a different chain.
• You could create an interchain nft collection where the NFTs have different properties based on the chain they’re currently on.

🏗 Best use of Hyperlane - $2,000 - Infrastructure

• With respect to infrastructure, here’s a chance to build infrastructure either for Hyperlane or build infrastructure for other protocols that uses Hyperlane.
• For example, a previous Hyperlane prize winner built infrastructure that supports Hyperlane relayers

💬 2 x Say My Name - $500

• fun/novel use of name and avatar resolution

🤝 Integration Bounty - $5,000

• distributed equally amongst all projects that resolve ENS names and avatars

1️⃣ Bounty 1:

With ERC-1271, smart contracts can now sign messages as if they were EOAs (Externally Owned Accounts, like MetaMask).

On CoW Swap, EOA users don’t pay gas and never pay for failed transactions because they sign messages to place their orders — but smart contracts don’t get these same benefits, since (before ERC-1271) they must place their order with an on-chain transaction.

🥇 We will award $5000 to the team that builds the most-creative demo of ERC-1271 to place orders on CoW Protocol, giving as many unique benefits as possible to smart contract users.

An extra $2500 is available if you attach an interesting front-end to your solution.

-----

2️⃣ Bounty 2:

Today, CoW Protocol is mainly used by traders leveraging the CoW Swap frontend.

Our target audience for CoW Swap is retail users that need a simple UI and want to avoid various blockchain complexities. But anyone can build a UI on top of CoW Protocol that is tailored to a different user profile (e.g. pro traders, smart contracts, exotic custom order-makers looking for TWAP, limit orders, etc.) — and these are all highly-desirable.

💻 We will award $2500-5000 (depending on the response to the first bounty) to the team that builds and deploys the most-creative frontend on top of CoW Protocol.

The goal is for your team to develop a dapp on Boba Network that incorporates our technology, Hybrid Compute, and gaming! For the challenge, your work must be shown through open-source code.

🏆 Best Use Case of Hybrid Compute: Create a gaming dapp (it can be a simple, but fun game) that is connected with WEB2 and deployed on the Boba Network testnet.

• 🥇 $10,000.
• Your solution can take data from WEB2 APIs and bring it on-chain, or be a web3 extension of an existing app... This challenge is industry agnostic with the only point being added value to the user. Hybrid Compute needs to be incorporated within the dapp, otherwise, the submission will not be considered.

🏆 Prizes:

ChainSafe Gaming is offering $2000 USD for the top project submission.

💰Prize Description:

ChainSafe Gaming is a complete web3 gaming solutions provider that recently released a new version of our SDK, web3.unity, that supports developers in building-enabled games and NFT-backed game assets. Web3.unity works on any EVM-compatible blockchain, and allows reads/writes and simplified wallet login across browser, mobile, and desktop platforms.

Web3.unity recently added new drag-and-drop prefabs for minting and selling NFTs directly in-game. Developers can now embed a full ERC-721/1155 NFT marketplace UI in their game to sell assets to players or allow peer-to-peer trading. Additionally, players can be rewarded with mintable NFTs when they complete in-game actions.

The ChainSafe Gaming team wants to see what YOU can build with these new NFT features. This hackathon prize is for the best game or interactive experience built with web3.unity’s embeddable NFT marketplace. 

⚠️Requirements:

• Your project must use the web3.unity in-game embeddable NFT marketplace prefab
• The marketplace must include NFTs that you have created specifically for the game and players must be capable of buying those NFTs directly from within the game through the ChainSafe Gaming marketplace
• Open source is preferred but not required. Code must be visible during judging
• Your project description must mention how you used the web3.unity marketplace and where in the codebase this usage can be seen
• Your project must have a live, deployed, public, and interactive demo that can be used by judges and other hackathon participants
• Your project must include a video presentation of the game and technology behind it, explaining how you used the marketplace prefab in your project
