🚀 SpiderHack by Botanix: the first EVM Hackathon on Bitcoin 🚀

Build the future of finance on Bitcoin! Join the Botanix SpiderHack!

Are you ready to revolutionize the world of decentralized applications built on Bitcoin?

Botanix 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.

🗣️ Who? Every developer who wants the opportunity to shape the future of finance on Bitcoin.
🗣️ When? SpiderHack runs from February 5 to March 31, 2024
🗣️ Why? Participants will develop innovative Bitcoin dApps while competing for a $50,000 prize pool!

What is Botanix?

Botanix 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!

In 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.”

With SpiderHack, the Botanix team wants to give developers:

  • Practical experience with an EVM-equivalent layer on Bitcoin
  • Education on how the future of Bitcoin L2s can function
  • Opportunities to compete for a $50,000 bounty
  • Relationships with the Botanix team and ecosystem to build on Bitcoin

Start 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.
