"},{"id":699,"name":"Bounties Details","slug":"bounties-details","description":"# Drosera\n\n## Build exploit/risk detection contracts with Drosera’s Trap framework\n\n**Bounty Description:**\n\n- Drosera is building the application security economy, innovating a new category of web3-native security products: decentralized incident response. dApps and middlewares utilizing our technology delegate security to a network of node operators using solidity smart contract code.\n\n**Resources for Hackathon:**\n\n- https://github.com/drosera-network/examples\n- https://github.com/drosera-network/trap-foundry-template\n- https://dev.drosera.io/docs/intro\n- https://de.fi/rekt-database\n- https://github.com/SunWeb3Sec/DeFiHackLabs\n\n**Prize Amount - $2,500**\n\nWhat is required to complete this prize?\n\nTo qualify for a prize, the developer must:\n\n- Fork the drosera examples repo\n- Create one or many Trap contracts that serve a use case for risk mitigation, exploit mitigation, or as an example for mitigating a real-world exploit in the past\n- Leveraging the examples, make a forge test showing how the Trap detects its incident\n- Optional: Hook the Traps isValid result up to a response function\n - This could involve deploying a new version of a protocol with a pause function that can only be hit by the Trap you created\n- NOTE: given that the Drosera protocol is still in development, a full integration is not required, just Trap creation.\n\n### What does success look like? What are possible features that you are looking for?\n\nOne path to success is creating a Trap that can detect a real-world exploit. Many exploits can be found in this rekt-database (https://de.fi/rekt-database). Defi Hack Labs also has a great repo for seeing past exploits with foundry (https://github.com/SunWeb3Sec/DeFiHackLabs). It also helps to have the mindset of trying not to reverse engineer an exploit but rather monitor what matters. Here is a good thread on the topic https://x.com/0xkr8os/status/1780299478664093879?s=46&t=qcKDEj-3e8-lrTfvoZn7tg\n\nAnother path to success would be to create a Trap that performs risk mitigation, some examples of this can be found in our example repo readme (https://github.com/drosera-network/examples). Lastly, creating Solidity libraries that could help in Trap Creation would also be a fine addition.\n\n### What are the UI/UX Design Requirements?\n\nGiven that the expectation is to develop a trap and testing it in foundry, there is no requirement on UI/UX. However, everyone likes a pretty picture, so we aren't opposed to something creative.\n\nWhat are examples of use cases you are looking to solve?\n\nCheck out the examples database for more insight. https://github.com/drosera-network/examples\n\n### How are you judging this bounty? What specific criteria do projects needs to be aware of?\n\nThe project will be judged for best use case of Trap performing exploit/risk detection, most creative Trap use case, completeness, and complexity. We are aiming to put the biggest weighting on whether the Trap solves a real-world exploit or the Trap can be used for risk mitigation for real protocols.\n\n### Is the use case meaningful?\n\nIt's important to understand that we are looking to see real-world use cases but we also believe that creativity is important to hackathons, in order to show what is possible.\n\n### Is the demo awesome?\n\nA demo can involve showing the trap simulation running and output from the trap detecting an incident and walking through the use case. It would be cool to see the trap running every block using a script also but that isn't required.\n\n# Movement\n\n### Move-Powered Modular Ecosystems with Movement Labs\n\nMovement Labs has developed the first modular framework that enables developers and projects to build and deploy Move-based infrastructure, applications, and blockchains in any distributed environment. This framework is designed to streamline the creation and deployment of Move-based systems across various networks. Their initiative not only enhances the capabilities of the Move programming language but also promotes its adoption across diverse sectors, including decentralized finance (DeFi), gaming, and non-fungible tokens (NFTs). Termed \"Limitless Integration,\" this approach allows developers to overcome traditional platform-specific barriers.\n\nTo further optimize development, Movement Labs champions a \"Unified Codebase,\" where a single codebase is utilized across multiple platforms, thereby reducing redundancy and increasing efficiency. This strategy is implemented in their flagship product, the Movement network. The Movement network operates on a permissionless basis and is currently implemented as a Celestia or EigenLayer rollup. Although Movement is still in the devnet phase, it is a pivotal development in redefining how Move-based blockchains are deployed and interacted with.\n\nThe Movement SDK, a crucial part of the Movement ecosystem, plays an essential role in this integrated network. It reduces the complexity of deploying decentralized applications across modular blockchain networks, enabling seamless integration for developers and infrastructure providers through a single command-line interface (CLI). By facilitating such integrations, Movement Labs ensures that developers have the necessary tools to create secure, efficient, and versatile decentralized applications.\n\n- Website:https://movementlabs.xyz/\n- Developer Docs:https://docs.movementlabs.xyz/\n\n### Development of Actively Validated Services (AVS) Using Movement Labs and EigenLayer Technologies\n\n**Bounty Objective:**\n\nThe goal is to challenge participants to leverage the unique capabilities of both Movement Labs and EigenLayer to develop AVS that enhance the Ethereum ecosystem.

Applications may include new virtual machines, data availability layers, oracle networks, bridges, and other innovative solutions that can operate under the shared security model of Ethereum, enhanced by EigenLayer.\n- Technical Requirements: Submissions must integrate EigenLayer’s capabilities with Movement Labs’ technology stack, particularly the Movement SDK. Solutions should demonstrate how they utilize EigenLayer’s restaking and other AVS functionalities to extend security and operational efficiencies within the Ethereum ecosystem.\n- Expected Outcomes: Projects should demonstrate practical applications of AVS in improving Ethereum’s scalability, and security, or adding new functionalities. The solution should showcase how the integration of Movement Labs and EigenLayer technologies can lead to significant enhancements in blockchain infrastructure.\n\n**Requirements for Participation:**\n\n- Participants must use the Movement SDK to develop their solutions.\n- Applications should be deployable on Movement, making full use of their infrastructure and capabilities.\n- Integration with EigenLayer's security features, like restaking, is encouraged to enhance application robustness and scalability.\n\n**Judging Panel and Criteria:**\n\n*Overview:* The judging panel will consist of industry experts with significant experience in blockchain development, smart contract security, and advocacy. Their role is to evaluate each submission based on the predefined criteria to ensure fairness and to identify projects that exhibit exceptional innovation, technical merit, and market viability.\n\n**Key Judge Introduction:**\n\nName: Jordan Bishop\n\nTitle: Head of Advocacy, Movement Labs\n\nExperience: With four years of extensive experience in blockchain development and smart contract security, Jordan has been instrumental in advancing Movement Labs' mission. As the Head of Advocacy, they facilitate all operations related to developer growth, including both internal and external initiatives aimed at enhancing the blockchain community's capabilities and integrating new technologies.\n\nName: Andy Golay\n\nTitle: Solutions Engineer, Movement Labs\n\nAndy has developed multiple viral applications within the gaming and NFT sectors on the Sui platform before its mainnet launch. He possesses substantial experience in mathematics education, encompassing both teaching and curriculum development. Additionally, Andy owned a prosperous Web2 business for several years, where he managed SEO, web application development, and creative production for a six-figure digital downloads and coaching business that employed two people.\n\nJudging Criteria for developers on movement:\n\n- Innovation: Originality of the application and its potential impact on the blockchain ecosystem.\n- Integration Quality: Depth of integration with EigenLayer’s and Movement Labs' technologies, demonstrating enhanced functionality and user experience.\n- Market Viability: Relevance of the application in addressing real-world needs and its potential for widespread adoption.\n\n## Prize\n\nTotal Bounty: $3,500 USDC + $30K in later grants\n\n- **1st Place:** $1,750 + $10k grant to continue building (must deploy mainnet)\n- **2nd Place:** $1,000 + $10k grant to continue building (must deploy mainnet)\n- **3rd Place:** $750 + $10k grant to continue building (must deploy mainnet)\n\n$500 for up to 10 honorable mentions\n\n# OpenLayer\n\n## Integrate with OpenLayer's oracle on Holesky testnet and request or use the provided commodity prices in the project.\n\n**Prize Amount: $1,000**\n\n- Docs: https://openlayer.gitbook.io/openlayer/get-started/openoracle/for-data-consumers\n\n- Website: https://openlayer.tech\n\n# Brevis\n\n## Build Data-driven dApps with Brevis ZK Coprocessor\n\n**Bounty Description** \n\nBrevis allows smart contracts to trustlessly read historical on-chain states/tx/events and run customizable computations on top at low cost, enabling data-driven dApp UX. No ZK knowledge is required. Build with Brevis and win amazing prizes.\n\nPrize Amount: To be announced later.\n\n- What is required to complete this prize?\n\nDevelopers are required to integrate Brevis SDK 2.0 into their dApps successfully.\nThe dApps should access historical blockchain states, transaction and/or events, and run customized business logic/computation on those data through Brevis ZK Coprocessor.\n\nThe integration should be meaningful: accessing historical states that are also available in the current blockchain states does not count as successful integration.\n\nTo qualify for the first prize, the dApp must write customized and meaningful computation logic on the data accessed. Simply utilizing historical on-chain data without any computation does not qualify for the first prize.\n\nWe do consider partial or incomplete integration on a case-by-case basis. For submissions aiming to solve real-world use cases with a clear path towards full integration, we will most likely issue the full amount of the bounty.\n\n- What does success look like? What are possible features that you are looking for?\n\nExamples:\n\nAn good example of a successful integration is a trading-volume-based fee discount feature in Uniswap v4. You can find example code for this in the Brevis SDK repo.\n\nTo understand the core concept of Brevis and what sample apps you can build with it, we recommend reading this blog post.\n\nOther examples and inspirations can be found in Brevis's blog and twitter. Specifically check out this introduction blog post\n\n- What are the UI/UX Design Requirements\n\nBasic UI is preferred to demonstrate the idea. However, it is not a hard requirement to qualify for bounties. We focus more on the core flow of integrating Brevis and the meaningfulness of such integration.\n\n- What are examples of use cases you are looking to solve?\n\n1. To understand the core concept of Brevis and what you can build with it, we recommend reading this Uniswap v4 hook example and this introduction blog post\n2. Some specific ideas are:\nUniswap v4 hooks based on traders' historical trading behaviors\n\nLoyalty and user retention features in DeFi, gaming and others\n\nUser-gating features based on historical user behaviors\n\nTrust-free active liquidity management solutions using Brevis to prove on-chain triggers\n\nSmart wallet recovery features based on user behavior and on-chain financial connections\n\n- How are you judging this bounty? What specific criteria do projects needs to be aware of?\n\nIs the use case meaningful? Many top-tier DeFi protocols are already solving real-world challenges and implementing features that were not possible before using Brevis. We believe you can do that too. Therefore, we put the biggest weight on whether the submission actually aims to solve a real-world challenge or to build a useful feature through the paradigm-shifting power of ZK coprocessors. Therefore, we also accept partial implementation submissions.\n\nIs the implementation complete? We also look at whether the implementation is well-executed. We are here to help.\n\nIs the demo awesome? We put less focus on UI/UX. However, amazing demo always helps to deliver the idea better!\n\n# WitnessChain \n\n## a. DePIN: Usecases on WitnessChain\n\nDwell down on WitnessChain DePIN usecases, design your tech and product roadmap & pitch to the team \n\n## b. WitnessChain empowered Rollup Watchtower\n\nThis acts as part of Track 6 where developers can build and execute logic on dApps dictated by rollup state & do more with watchtowers.\n\n## Benefits:\n\n- get a chance to join the team\n- your project gets resources and incubation support from the team\n\nhttps://docs.witnesschain.com/diligence-watchtowers/introduction\n\n# Polymer \n\n## Implementation Guide: Cross-Environment Operations Bridge\n\n**Prize Amount: $10,000**\n\n### Objective:\nDevelop a operator registry and multisig contract that operates across Optimism and Base Sepolia using Polymer. This system should integrate a mechanism where Polymer-related events on Sepolia could theoretically trigger AVS-specific actions on Holesky (via off-chain event listeners or lite nodes). The full vision of this project will need to implement a two-part system: a operator registration and multisig contract on Optimism and Base Sepolia, and a parallel AVS management system on Holesky. These systems will interact with each other to send data, and ensure security measures across multiple chains. The Objective of this Hackathon bounty is to implement the first part of this system: an operator registration and multisig contract that operates across the Optimism and Base Sepolia networks using Polymer. This application is foundational, enabling the future integration of an AVS that will verify and potentially implement slashing mechanisms for disputed transactions.\n\n### System Overview:\nThe Polymer bounty project involves creating a cross-chain multisig contract that functions across Optimism and Base Sepolia using Polymer Hub. This will later enable an AVS to verify transactions and enforce security measures such as slashing in cases of disputes. Development Focus Areas:\nPolymer Cross-Chain Transactions: Implement and test secure cross-chain multisig transactions.\nEvent Handling: Design mechanisms to handle events that are critical for multisig operations and future AVS integration.\n\n### Implementation Steps:\n1. Multisig Application Deployment:\n- Deploy a multisig smart contract on both Optimism and Base Sepolia that interfaces with Polymer’s infrastructure.\n- Design the contract to handle cross-chain transactions and to be capable of initiating events that need to interact with the AVS system on Holesky.\n1. Operator Registry Smart Contract: Create a smart contract that manages node operators' addresses and signatures across both chains, enabling secure operations and verification processes.\n2. Documentation and Standardization:\n- Document the entire process, focusing on the interaction between multisig transactions and AVS responses.\n- Standardize the interface calls to align closely with IBC standards, ensuring that the system is robust and can be extended or adapted in the future.\n\n### Innovation:\nThis project addresses the foundation to integrate AVS’s into blockchain interoperability solutions. AVS’s can solve challenges of blockchain interoperability by enhancing both performance and security across different blockchain environments. Creating a multisig contract that communicates over two different blockchains, opens up possibilities for more complex and secure decentralized applications that can operate across multiple blockchain ecosystems, which can be secured through an AVS. Integrating and AVS not only adds additional security on-top of the multi-chain multisig, but also could improve the finality and speed of cross-chain transactions by pre-verifying transactions. \n\nFull writeup here: https://forum.polymerlabs.org/t/hack-avs-polymer-bounty/746\n\n# Inco Network\n\n## Killer use case leveraging Confidential Compute\n\n**Prize Amount: $2,500**\n\n**Bounty Description:** \n\nUtilize our cutting-edge FHE (fully homomorphic encryption) tech to deploy confidential smart contracts with our fhEVM (FHE + EVM).

Organized by Hacker Dojo, we are thrilled to invite you to participate in HackAVS, the first-ever AVS-centric hackathon. This is your chance to win exciting prizes and contribute to the flourishing EigenLayer ecosystem! 🔥\n\nThe hackathon officially kicks off from April 23rd. We welcome all hackers who are eager to innovate using [Eigen Layer’s AVSes](https://ethrestaking.com/avs). Read on for more details!\n\n# Key Dates (Updated)\n\n- Kicking Off: April 23\n\n- Live workshops: April - June \n\n- **Submission deadline: July 20 23:59 UTC**\n\n- Judging: July 20 - 30\n\n- Demo days: June 20 - 30\n\n# Tracks\n\n**Track 1: ETH Roadmap Expansion and Acceleration with EigenLayer**\n\n**Description:** Ethereum is plotting a more inclusive and brighter future with EIP-4844 & danksharding and EigenDA align perfectly with it. This opens the innovation floodgates for developers to build high throughput dApps with ease, it also comes with much lower latency for rollups settling to Ethereum which makes real-time gaming, social dApps, AI co-processors & more possible with a very seamless experience.\n\n**Track 2: Open Source Explorers & Restaking Intelligence**\n\n**Description:** EigenLayer has unleashed a whole new spectrum of deFi which also called for open source explorers and deFi tooling, which is not just limited to yield optimising tools but event-driven activation, portfolio management & automation, MEV capturing, staking dashboards, EigenLayer block explorer, L2 beat for operators & more\n\n**Track 3: AVS Tooling**\n\n**Description:** With multiple AVS’es stemming from the growth of EigenLayer, the teams also want strong tooling to strengthen the roots, like- Operator payment calculator, cost optimiser, decentralised governance tools, developer onboarding toolkits, auto compounding for operators, open-source AVS frameworks, snapshot voting for AVSs, operator configuration, automation for AVS, & more\n\n**Track 4: Decentralised Oracles**\n\n**Description:** Decentralised Oracles bring in a vast variety of use cases like prediction markets, decentralised exchanges, Insurance data, Election results & more. dApps surrounding the following use cases will be able to connect their smart contracts with any type of data from the external world and build dApps like AVS specific CLOB, token factory on AVS, on-chain stock/equity trading etc.\n\n**Track 5: All things ZK**\n\n**Description:** ZK Technology paired with restaking unlocks a ton of potential for dApps including zkBridges, larger interoperability/ cross-chain use cases, ZK rollups & more. This track will include everything ZK like BTC scaling, ZK/ Optimistic rollup watchers & actors, etc\n\n**Track 6: DePIN**\n\n**Description:** While a ton of actions/ smart contracts/ rollups are enabled on EigenLayer, watchtowers enable physical decentralisation while unifying various DePIN actions and economics to one layer with- Proof of Diligence, Location & Bandwidth. Developers can build and execute logic on dApps dictated by rollup state & do more with watchtowers.\n\n**Track 7: Cosmos EigenLayer Alignment**\n\n**Description:** Crypto economic security can be diversified using different blockchains and expanding the use case beyond Ethereum. This could bring in ideas like launching a use case-specific AVS with security from Ethereum + Cosmos SDK framework, IBC-enabled AVS, restaking on Cosmos & more\n\n**Track 8: Nostr EigenLayer - Content Storage, Social, and Decentralized Media**\n\n**Description:** Adding economic security guaranteed programmability to Nostr will expand the capability of Nostr protocol. The alignment will enable a wide range of decentralized content applications, including social, media, and other content creation activities.\n\n# **Entry Requirements**\n\n1.
