It's truly impressive to note that over 60 teams dedicated their efforts to developing innovative Bitcoin dApps, all vying for a share of the $50,000 prize pool! Without further ado, let's take a look at the finalists!\n\n### 🥇 First Prize\n\n[BUIDL](https://dorahacks.io/buidl/10864)\n\nBUIDL link: https://dorahacks.io/buidl/10864\n\n### This is a project to create a trust minimized bridge between Botanix and the Lightning Network. The goal is to allow for the creation of smart contracts that can make trust minimized payments to the Lightning Network. This really only makes sense in the context of chains using Bitcoin as their native currency, but it could be extended to other chains as well. The project includes smart contracts with tests, a frontend, and a Lightning Service Provider (LSP) server which facilitates the lightning payments.\n\n### 🥈 Second Prize\n\n[BUIDL](https://dorahacks.io/buidl/10848)\n\nBUIDL link: https://dorahacks.io/buidl/10848\n\nThe Secure and Seamless Crypto Wallet for the Future. Anansi simplifies your crypto journey, regardless of the chain. Our innovative wallet eliminates private key management with secure passkey login and offers gas-free transactions (Botanix TestNet). Built on cutting-edge technology, Anansi leverages ERC-4337 standards, showcasing the power of Account Abstraction we implemented on the Botanix blockchain (Bitcoin Layer 2).

Join the Botanix SpiderHack!*\n\nAre you ready to revolutionize the world of decentralized applications built on Bitcoin? \n\nBotanix Labs invites you to the SpiderHack, the first Spiderchain hackathon event to create innovative EVM dApps on Botanix, the first EVM-equivalent Layer 2 running on Bitcoin.\n\n🗣️ Who? Every developer who wants the opportunity to shape the future of finance on Bitcoin.
\n🗣️ When? SpiderHack runs from February 5 to March 31, 2024
\n🗣️ Why? Participants will develop innovative Bitcoin dApps while competing for a $50,000 prize pool!\n\n# **What is Botanix?**\nBotanix makes innovation on Bitcoin easy with the first EVM-equivalent Layer 2 on Bitcoin, called the Spiderchain. In fact, building on Bitcoin is almost as simple as copying and pasting any existing EVM smart contract and deploying it on the Botanix testnet. Transform any Ethereum application into a plug-and-play solution on Bitcoin!\n\nIn a brand new paper, Jameson Lopp reviewed the Botanix Labs whitepaper and noted its simplicity. He wrote, “While there are a variety of proposals being discussed for enhancing Bitcoin's Layer 2 capabilities […] one distinction with Botanix's Spiderchain is that it can be implemented on Bitcoin today without any protocol changes to the base layer.”\n\nWith SpiderHack, the Botanix team wants to give developers:\n\n- Practical experience with an EVM-equivalent layer on Bitcoin\n- Education on how the future of Bitcoin L2s can function\n- Opportunities to compete for a $50,000 bounty\n- Relationships with the Botanix team and ecosystem to build on Bitcoin\n\nStart by exploring the live Botanix Labs Testnet where you can experience the power of EVM on Bitcoin firsthand. With forward security as a key feature, Botanix is optimized for a network with low fees and fast transactions running on Bitcoin.\n\n# SpiderHack Requirements\n## What to build?\nParticipants are encouraged to consider building a submission that fits in one of the following categories.\n\n- **DeFi (Decentralized Finance)**: Leverage Bitcoin's security and transparency for innovative financial services from decentralized lending and borrowing to commerce and exchange.\n- **NFTs (Non-Fungible Tokens)**: Unlock the intersection of Bitcoin and digital collectibles with the immutable Bitcoin blockchain.\n- **GameFi (Gaming Finance)**: Fuse the worlds of gaming and Bitcoin by integrating Bitcoin-based applications into gaming economics and assets.\n- **Bitcoin Infrastructure**: Optimize Bitcoin's technical foundations for scalability, interoperability, and network efficiency by addressing critical issues related to transaction throughput.\n- **DAOs (Decentralized Autonomous Organizations)**: Develop governance structures and decision-making mechanisms on Bitcoin that enable decentralized social control.\n- **Social Impact**: Address real-world challenges with an emphasis on positive social impact using the power of Bitcoin's security and transparency.\n- **Creative Mode**: Unleash your personal creativity and explore untapped possibilities with Bitcoin. Let your imagination run wild and submit any application that expands the value and utility of Bitcoin.\n\n## What to submit?\nHere are guidelines for complete submissions and disclosures. \n\n**Submission Guidelines:**\n\nAll submission need to deploy to the Botanix Testnet and include the following:\n\n- Incorporate unique use cases or implementation\n- Demo video up to 3 minutes long\n- Text description explaining the features and functionality of your submission\n- Open source Github repository with a complete README\n- Links to participant’s website and socials to help judges review your submission. If the participant’s website is private, the project must include login credentials in its testing instructions.\n- Method for testing the project (e.g., link to the app or testing instructions)\n- All submission materials must be in English, including the demonstration video, text description, and testing instructions, as well as any other materials submitted.\n- Complete submission form by the final deadline\n\n**Multiple Submissions:**\n- Entrants are allowed to submit more than one submission. However, each submission must be unique and substantially different from the others.\n\n**Disclosure:**\n- Projects submitted to other hackathons or challenges need to be disclosed in the submission or README of the project.\n\n# Prizes and Exclusive Opportunities\n### 💰 $50,000 Bounty Pool\nAll participants in the SpiderHack event will compete for a total bounty of $50,000 provided by Botanix Labs. Winners will be awarded for building the best applications using the spiderchain to showcase the power of an EVM-equivalent layer on Bitcoin.\n\n- First Place: $25,000\n- Second Place: $10,000\n- Third Place: $5,000\n- Most Creative Project: $5,000\n- Best Technical Project: $5,000\n\n### 🌟 Exclusive Opportunities\n\nTop developers from SpiderHack will have a chance to meet with the Botanix team and explore potential partnerships as official builders in the Botanix ecosystem. After the SpiderHack event, these builders will receive dedicated marketing, growth and development resources to take their projects to new heights on Bitcoin.\n\n\n# Judges\n- Willem Schroé (Co-Founder & CEO of Botanix Labs)\n- Alisia Painter (Co-Founder & BD Lead at Botanix Labs)\n- Armin Sabouri (Co-Founder & CTO at Botanix Labs)\n- Patrick Bush (Senior Investment Analyst at VanEck)\n- Vikash Singh (Principal at Stillmark, the Bitcoin VC Fund)\n\n# Judging Criteria\nSubmissions will be evaluated based on the following criteria:\n \n- Implementation Quality: Does the project demonstrate high-quality development: clean, efficient and safe code, tests, documentation, usage of the version control system?\n- Innovation: Does it solve a problem in a creative and unique way?\n- User Experience: Does the project’s design make the user experience seamless?\n- Originality: Does the project represent a creative, unique, and well-thought-out idea? \n- Potential Impact: How large of an impact could the project have?
