Integration with the new Biconomy SDK takes only minutes and allows easy plugging, stacking, and customization of APIs and modules that result in many UX benefits, including one-click user journeys, transaction bundling, and control over gas fees.

KEY Benefits of #BiconomySDK:

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

You must deploy a use or build on the Biconomy SDK to qualify for the Prize. Inside the project README file, you can write a short paragraph noting the Prize you are targeting and describing how your hack solves the problem statement. Please tell us what you’re building on #BiconomySDK by tagging @Biconomy on Twitter.

🥇 $3,000 - Best Module on Biconomy SDK

We believe that all Web3 users need a smooth and secure experience delivered efficiently. With Biconomy SDK, you can create smart contract wallets for your users. Create tooling or modules on SDK to improve and extend smart contract wallet functionality.

Some examples:

• You could create social recovery functionality to help users recover their smart contract wallet.
• You could create session keys to abstract repetitive user signatures and improve the user experience.
• You could optimize the gas used for smart contract wallet creation.
• You could build tooling to automate transactions on a smart contract wallet.
• You could build tooling to protect smart contact wallet users from MEV bots.
• You could build a multi-signature module on top of smart contract wallets.

🥈 $2,000 - Best Transaction Batch using Biconomy SDK

Today the need to sign every transaction individually leads to a complex multi-step user experience. With Biconomy SDK, you can batch transactions to create one-click flows. We are looking for impactful transaction batches which reduce user clicks, save on gas fees and save the user time. A great way to shoot for this Prize is to attempt to make transaction batches for the most innovative & widespread use cases.

For example You could create a use-case to batch to sell an NFT, swap those tokens to ETH with Uniswap, stake on Aave and reinvest the yield into ETH. Make it one click instead of asking for more than ten user signatures across four different platforms.

You could create a UI where users can make their transaction batches using smart contract wallets.

🏊‍♀️ $5,000 - Biconomy will grant $250 to dApps that integrate the Biconomy SDK, uses the smart contract wallets to build offer UX flows, and has a working demo/dapp (max 20 projects).

🧠 Smart integration of Instadapp: 2 teams win $2,000 per team.

While we encourage hackers to come up with their own ideas, here are some to pick your brain:

Creative Ninja - Build Recipe maker (batch transactions). Create a recipe maker which would batch multiple transactions into one using dsa-connect SDK. E.g., create DSA, supply, and leverage in one click.

Scripting Ninja - Create an automated refinancing script that would automatically refinance the position to another protocol if it’s risky. The script can check the current ratio of position and potential ratios on other protocols, and whichever has the least ratio will initiate an automatic position transfer to that protocol.

DeFi Ninja - Build Limit Order contracts on Uniswap. When a user will create a limit order, create a small position on the nearest tick to the price using a smart contract and send a closing transaction whenever the price crosses that position through the backend.

Coder Ninja - Build a whitelisted manager contract. Create a contract that will be an authority on DSA and can whitelist connectors.

Hyperlane is an interoperability platform providing an interchain messaging API empowering you to easily and securely communicate between blockchains. You can use Hyperlane to build interchain applications, or you can use it to conduct actions on remote chains without deploying any contracts by leveraging Hyperlane's Interchain Accounts.

🥇 $4,000 - 'Best use of Hyperlane' interchain API - To win this prize you simply need to build an application that utilizes the Hyperlane 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. - Another application we would love to see if a Blockchain Smart Router. Imagine being able to route computation to the cheapest blockchain within the Hyperlane network, and then being able to retrieve or read that state whenever necessary from your home chain. Effectively turning any blockchain into your layer 2 and beyond. This will be incredibly challenging to build, but the rewards will be far greater than you can imagine!

💸 $2,000 - Best use of Hyperlane - 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 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 an interchain lending app, allowing borrowers to borrow against collateral from a remote chain. 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.

🌠 $2,000 - Best use of Hyperlane - 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.

🏗 $2,000 - Best use of Hyperlane - Infrastructure, Governance, or Gaming - With respect to infrastructure, here’s a chance to build infrastructure either for Hyperlane or build infrastructure for other protocols that uses Hyperlane. - More specific applications and examples include: SAFE based app would be one that allows you to create a SAFE on one chain, and use any app on any Hyperlane supported chain from that SAFE. An EIP 5164 implementation A Tally or other Governance related integration - Lastly, an example we'd love to see built would be a modification with Hyperlane mailboxes or agents (relayer and validator) binaries to make them compatible with non-EVM environments such as Cosmos, Fuel, and others. - On the gaming front, either a game, or gaming related infrastructure would qualify.
