We are challenging you to help to build the future of financial applications and grow the DeFi ecosystem with GHO and the Aave Protocol. The prizes below are available for the best projects on GHO and/or Aave: 🥇 $3,500 USDC 🥈 $2,500 USDC 🥉 $1,500 USDC 5️⃣ Plus the 5 best GHO integrations will receive $500 USDC each Here are a few ideas to get your creative juices flowing! **GHO** ***Payments***: Build utility around the future of payments on the web. You could create an app or plugin to buy and pay with GHO anywhere. ***Direct Debit Network***: Create a direct debit network for GHO where any user can charge an account with a predefined amount of GHO. GHO would then be transferred immediately but not unlocked until a set period of time passes. During this time, anyone can dispute the function if they have a balance. ***Account Abstraction***: Build a tool that uses Account Abstraction with GHO to allow users to pay gas fees with GHO, and has rebates. E.g., if the gas used is more than GHO paid, users can claim a rebate or pay it forward. ***DeFi Yield Strategies***: Construct new DeFi yield strategies and opportunities for GHO and the entire DeFi community. ***Dashboards and Leaderboards***: Monitor and analyze GHO’s top borrowers and liquidators, what assets are being used as collateral to back GHO, a GHO multi-chain dashboard. ***Transactions***: Create new ways to compose or visualize GHO transactions, such as supplying and minting GHO in a single transaction. ***Credit Delegation***: Allow users with supplied collateral to delegate their borrowing power to other users. Instead of paying to borrow an asset, you could get paid to [delegate credit to other users (via ERC712 signature)](https://github.com/aave/aave-v3-core/blob/29ff9b9f89af7cd8255231bc5faf26c3ce0fb7ce/contracts/protocol/tokenization/base/DebtTokenBase.sol#L43) for sponsored (gasless) mints. **Aave** ***Health Factor Simulator***: Build a UI component that displays a price slider per each collateral and borrowed asset, so you can simulate prices and see how your Health Factor changes under those conditions. Allowing you to take informed decisions to mitigate liquidation risks. ***Debt Swap***: Right now you can swap your collateral from one asset to another but imagine if you built a new feature for swapping debt from one asset to another. ***Governance Visualizations***: Create visualizations to help show aspects of the very active Aave Governance, such as, access controls, voter participation, delegation. ***DAO Tooling***: Build tools to help the Aave DAO community. ***Aave Forex Tool***: Build a tool where you can short assets. Enhance the ability of users to access forex liquidity by using one or all of eMode, flash loans, and other DeFi integrations such as Curve. ***ZK Proofs***: Utilize ZK proofs for critical vulnerabilities while not disclosing the vulnerability, i.e. prove there’s a vulnerability to the DAO so they can vote on it informed but not actually say what the vulnerability is. ***Sponsored Transactions***: Create sponsored (gasless) transactions using functions to [supply](https://github.com/aave/aave-v3-core/blob/29ff9b9f89af7cd8255231bc5faf26c3ce0fb7ce/contracts/protocol/pool/Pool.sol#L165) and [repay](https://github.com/aave/aave-v3-core/blob/29ff9b9f89af7cd8255231bc5faf26c3ce0fb7ce/contracts/protocol/pool/Pool.sol#L273) via permit function, [credit delegation](https://github.com/aave/aave-v3-core/blob/29ff9b9f89af7cd8255231bc5faf26c3ce0fb7ce/contracts/protocol/tokenization/base/DebtTokenBase.sol#L43), transfer aTokens with permit, or [submit votes by a signature](https://etherscan.io/address/0xEC568fffba86c094cf06b22134B23074DFE2252c#writeContract#F11). Make sure your code is well documented on GitHub and preferably has a front end that is available to be used on a public website. If you created smart contracts, deploy them to a testnet and ensure your front end properly interacts with them. **Tell us what you are building by tagging @GHOAave @AaveAave on Lens and Twitter!**

🥇 $3,500 🥈 $2,500 🥉 $1,500 5️⃣ 5x $500 for 5 runner up Lens integrations ### Ideas for builders Below are some ideas of what you can build with the Lens ### Social Networking Powered Apps! ☀ AI-based music generation apps and marketplace that splits revenue with creators like [Grimes](https://twitter.com/Grimezsz) ☀ Mobile apps for sending, receiving and possibly buying cryptocurrency with social features and discovery (think web3 Venmo) ☀ Microblogging - Lens is perfect for a CMS type back-end with the added benefits of discovery, composability and user monetization via collects ☀ Specialized, or niche, marketplaces for digital art or collectibles ☀ Peer-to-peer messaging apps with end-to-end encryption ☀ Voting apps for elections, surveys or just for fun ☀ Digital identity management systems ☀ Social networks for content creators with revenue sharing ☀ Decentralized platforms for crowdfunding or fundraising ☀ Platforms for creating and selling digital subscriptions ☀ Web3-based social gaming platforms ### Tools Because all of the infrastructure, data and Lens APIs are open and permissionless, there are infinite ways to build new and interesting tools on top of the Protocol. ☀ Disqus-like commenting modules ☀ Creating, curating, and / or managing content ☀ Open-source SDK’s, UI Components and Libraries ☀ Leveraging new modules to build slick or improved user interfaces for interacting with existing modules ☀ Migrating web2 footprints to Lens (like [InLens](https://inlens.xyz/)) ☀ Content discovery ☀ Delegate profile actions to other wallets/s, smart contracts or DAO ### Integrations In addition to building applications directly on Lens, you may want to integrate Lens as a web3 social layer into other new or existing applications. Each application using Lens benefits the entire ecosystem, turning what is usually a zero-sum game into a collaborative one. Here are a few examples of integrations: ☀ Sign in with Lens - access users' profile information, such as name, bio, social URLs, pictures, interests, reputation, and activity. ☀ Share to Lens - helps distribute your application and its content to a larger audience. ☀ Follow on Lens - Follow a user on Lens from another app. ☀ Profile - display users' social profiles in any web3 application. ☀ Publication - Embed Lens posts content into any web3 application. ### ERC 6551 Token Bound Accounts (TBAs) gives every NFT it's own wallet An NFT's primary function is to enable uniqueness onchain, which typically can be done with image generation, contract utility, community formation, metadata and traits. However, there are clear limitations that prevent NFTs from reaching it's full potential as a self-sovereign Ethereum identity. ERC 6551 which is already deployed to mainnet assigns an account address (ERC 4337 to be exact) to every single NFT on the Ethereum ecosystem. This allows NFTs to be used as sign-in identities within all dapps and also allow for NFTs to create their own history onchain separate from the EOA wallet that owns it. Token Bound Accounts work exactly as a wallet and can hold any types of assets such as ETH, ERC 20, 721, 1155, etc. that means your NFT now can own other NFTs. The play area is extremely wide and fun because it allows for NFTs to truly be unique and become an NPC (networked playable character). JPEG - view, share, like NFT - buy, sell, trade NFTs with Token Bound Accounts - become, use, interact ☀ The design space here is huge, it would be amazing to see Lens integrations with ERC 6551 in some way. ### Monetization Mirrors, collects, follows and comments allow creators to monetize their content directly to the user without intermediaries and in a permissionless way. Because creators own their content via the Lens Protocol, they can allow their followers to purchase that content. When a user posts a publication to their Profile NFT, they have the option to set a Collect Module. This allows users to mint NFTs that link to the publication's ContentURI. This module can contain any arbitrary logic to apply to the minting process and the resulting NFT. Creators can incentivize promotion of their posts by offering fees for each post collected through one of their mirrors. Here are a few examples of what you can build into your app: ☀ Monetize audiences via paid subscriptions ☀ Incentivize people who share (mirror) content ☀ Split revenue between the creator and others (multiple recipients) ☀ Gated content based on collects or payment ☀ Marketing and ads ### More ideas For more ideas, check out the [Inspiration for builders](https://www.notion.so/Inspiration-for-Builders-1db7dbd3e7b14eaf9a97a341b1a3ff55) section of our docs.
