\n\n\n\n# ☁️ Avalanche\n\n

\n\n**DApp, Custom AppChain, and Virtual Machine Track - TBW Hacker Toolkit**\n\n
\n\n🏆 **Total Bounty = $5,000**\n\nParticipants in this track have free-range to decide how they want to build a DeFi, NFTs, gaming, infra/tooling, or any other application. Hackers can build and deploy a dApp for any purpose on Avalanche C-Chain (the Avalanche Primary Network), or they can go an extra step and deploy a Subnet specifically for hosting their dApp. If you have any questions about development on Avalanche, you can reference our [developer documentation](https://docs.avax.network/) or visit our [Discord](https://chat.avax.network/) to ask any questions.\n\n
\n\n**Selection Criteria**\n\nThe only criteria for a chance to win our bounties is that developers build on Avalanche.\n\n
\n\n**Bounties**\n\n🥇 1st Place - $3000\n\n🥈 2nd Place - $1500\n\n🥉3rd Place - $500\n\nYou can pick between these different tracks for your submission, the goal was to keep the bounty open-ended, feel free to ask us if you have any ideas and you don’t think they fall under any of these tracks. You’ll get bonus points for completing the Subnet track!\n\nIf the submission is exceptionally impressive, and the team behind its development is interested in pursuing its development further, there is potential for support and consideration for investment in the future from the Avalanche Blizzard Fund.\n\n
\n\n**Tracks**\n\n**C-Chain EVM Track**\n\n**For this track, the only requirement is to deploy a smart-contract based application on the [Fuji testnet](https://docs.avax.network/build/dapp/chain-settings). You’re free to be creative and work across any vertical (DeFi, NFTs, gaming, infra/tooling etc.)**\n\n- Create a dApp using solidity, rust, move, or any smart contract language and deploy it to the C-Chain of the Fuji Testnet\n- Extra: Integrate the [Core wallet](https://support.avax.network/en/collections/3391518-core) in the frontend\n - [React Template](https://github.com/ava-labs/avalanche-dapp-sdks/tree/alpha-release/packages/web3-react-dapp-example)\n- Hint: If you want to focus on dApp development, you can deploy a devnet using [Ava Cloud’s free tier.](https://avacloud.io/) and deploy that application on the Subnet-EVM based Devnet. This is a great way to get more attention during judging.\n\n- https://chainlist.org/chain/43114\n\n- https://chainlist.org/chain/43113\n\n
\n\n**[Subnet](https://docs.avax.network/learn/avalanche/subnets-overview) Track**\n\n**The goal here is to deploy your own [Avalanche Subnet](https://docs.avax.network/build/subnet/deploy/fuji-testnet-subnet) on the Fuji testnet and play around with customizing it (you can either use [existing stateful precompiles](https://docs.avax.network/subnets/customize-a-subnet), or [create your own](https://docs.avax.network/subnets/hello-world-precompile-tutorial)). Hint: You can deploy solidity apps the same way you would on Ethereum or Avalanche C-chain.**\n\nThread explaining Subnets in simple terms: https://twitter.com/martin_eckardt/status/1708431275126599703\n\n- Create an Avalanche Subnet with [subnetEVM](https://github.com/ava-labs/subnet-evm)\n- Pick an existing protocol or smart contract and fork it, or write your own smart contract based app (*DeFi, NFTs, gaming, infra/tooling etc.)*\n- [Deploy the subnet on the Fuji testnet](https://docs.avax.network/subnets/create-a-fuji-subnet)\n- Deploy and run the protocol / smart contract on the subnet\n- Extra:\n - Use precompiles to make the subnet permissioned (only certain wallets can deploy contracts or interact with contracts)\n - Issue own gas token, come up with tokenomics, custom gas fee structure etc.\n - Create your [own custom precompile](https://docs.avax.network/subnets/hello-world-precompile-tutorial).\n\n**Deliverables:** Ideas for customization, implementation, no front-end needed\n\n![youtbe](https://www.youtube.com/watch?v=KZUbqmGPUdE)\n\n
\n\n**Custom Virtual Machine Track**\n\n**The goal here is to use the Hyper-SDK to create a custom Virtual Machine.**\n\n[Virtual Machines](https://docs.avax.network/learn/avalanche/virtual-machines) are the blueprints that dictate a specific blockchain. Like how the EVM defines the Ethereum Blockchain, you too can create a custom virtual machine to run a blockchain.\n\nHyper SDK [GitHub](https://github.com/ava-labs/hypersdk#readme) repository\n\n- Examples located [here](https://github.com/ava-labs/hypersdk/tree/5103b305c00cab0160bdb14e49983475080d4990/examples) in the above repo\n- Community projects can be found at the bottom of the page.\n\n[Basic VM Tutorials](https://docs.avax.network/build/vm/create/golang-vm-simple)\n\nHyper SDK example [front-end](https://x.com/_patrickogrady/status/1704532717881475215?s=20) written by our VP of Engineering, you can fork if it suits your use case\n\n- Build a custom VM for a specific usecase\n- [Deploy a Subnet](https://docs.avax.network/build/subnet/deploy/fuji-testnet-subnet) for it\n- [Run a node](https://docs.avax.network/nodes/run/subnet-node) that tracks it\n- Show some example transactions\n - This does not mean you need to build a front-end like in the examples – just show us how the transactions work\n\n**Deliverables:** Use case for a blockchain with a custom use case, POC implementation, no front-end necessary\n\n
\n\n**Come up with your own project**\n\nReach out to us if you have a different idea that does not fit in any of the above tracks.\n\n

\n\n**Tracks/Challenges**\n\n**The challenge is to develop an intelligent crypto derivatives trading bot that can navigate the volatile cryptocurrency trading environment and generate consistent profits while minimizing risk.**\n\n
\n\n**Objective**\n\nDevelop a trading bot that can autonomously execute trades on BitMEX.com. Your trading bot should:\n\n- Trade Derivatives (Perpetual or Future contracts) or Spot contracts.\n- Watch the Market: Your bot should keep an eye on market trends and numbers to understand what's happening.\n- Find Opportunities: Like a treasure hunter, the bot needs to employ a specific trading strategy. This could be trend following, mean reversion, DCA, martingale or any other profitable strategy.\n- Play It Safe: The bot should know when to take a break if things on the market start getting too unpredictable or if it's losing more than expected.\n\n
\n\n**Requirements**\n\n- Autonomous Operation: The bot should be able to function independently without manual intervention once activated.\n- API requirement: Participants must trade via BitMEX's official API and may further engage external platforms such as Tradingview to access real-time trading data and signals.\n- Strategy Implementation: You should define and implement a specific trading strategy. This could be trend following, mean reversion, arbitrage, or any other established strategy. Innovation is welcome!\n- Trading Volume: The bot must reach a minimum trading volume of $50,000 within 6 hours.\n- Risk Management: It's not just about making profits; it's about managing risk effectively. The bot should have a risk management protocol to protect capital.\n- Documentation: Submit a brief report or documentation explaining the logic and strategy behind the bot, technical challenges faced, and any insights gained from the trading data.\n- Submit the algorithm via either a github project, gist or a python script running on our partner platform Profitview.\n\n
\n\n**Key Performance Indicators (KPIs)**\n\n**The trading bot must run at least 6 hours in live market conditions for it to be evaluated.**\n\nPrimary KPI: %-ROI - The Return on Investment based on the total trading profitability divided by the total capital provided.\n\nSecondary KPIs:\n\n- Average Win to Average Loss Ratio: The ratio between the average profit from winning trades and the average loss from losing trades.\n- Uptime: The percentage of time the bot is operational and monitoring the markets.\n- Responsiveness to Market Shocks: How the bot reacts and adapts to sudden and significant market moves.\n\n
\n\n**Judging Criteria**\n\n- Performance (50%): Based on the above KPIs, especially profitability and risk management.\n- Innovation (30%): Novel techniques or strategies implemented by the bot.\n- Documentation & Presentation (20%): Clarity, comprehensiveness, and understanding of the strategy and bot operations.\n\n
\n\n**Resources**\n\nParticipants of the BitMEX Hackathon Challenge must have a verified BitMEX Trading account.
