BUIDL Bitcoin

Main Track

Attention all developers, designers, and crypto enthusiasts!

Are you ready to take Bitcoin to the next level?

Bitcoin is the king of crypto, but it's been held back by limited programming capabilities, low speed, and high fees. That's where the Internet Computer (IC) comes in. With the native Bitcoin integration, you can unleash the full potential of Bitcoin and build innovative DeFi solutions without the need for custodians. Plus, with ckBTC, a smart contract controlled 1:1 Bitcoin-backed IC-native token, you can create low-latency payment solutions with fees of only a fraction of a cent and plug into a growing ecosystem IC native tools and services.


The IC provides the Layer 2 functionality for Bitcoin you’ve been waiting for.

Unleash the power of Bitcoin’s liquidity with the Internet Computer's superpowers:

• Host websites and interact with canister smart contracts directly from your browser 

• Smooth user onboarding with the reverse-gas model - no wallet necessary 

• Secure login with a security key or biometrics 

• Leverage enormous computational power and storage at low cost

• Call APIs directly from a canister -  no oracles required

• Flex your programming muscles with familiar languages like TypeScript, Python, and Rust, or master Motoko, the tailor-made language designed to streamline development on the Internet Computer

• Canister smart contracts are upgradeable and can be community governed. Allowing you to turn your app into a DAO or autonomous open internet service whenever you are ready.

But hold onto your hats, because there's more! The Internet Computer cannot only integrate with Bitcoin, but it has the ability to interact with many other chains. So, if you’re an Etherean or a Multicoiner, you'll also have the golden opportunity to explore and build on the first phase of the IC’s Ethereum integration.

The sky's the limit!

Join us to revolutionize the world of DeFi and commerce and unlock the untamed power of Bitcoin!

What you can build:

• New kinds of non-custodial Bitcoin wallets with simplified multi-sig processes, advanced policies, or social recovery functionality

• Payment solutions for physical and virtual commerce

• Non-custodial Ordinal marketplaces

• Bitcoin-backed Stablecoins, lending protocols, or other DeFi integrations

Blue Skies Track

Not a Bitcoiner? For all of you who want to leverage the unique superpowers of the Internet Computer to build an awesome project that’s not related to Bitcoin or want to create infrastructure or tooling to make developing on the Internet Computer simpler or more powerful, we got you covered. 

For inspiration, check out the Request for Startups, but don’t feel restricted by our limited imagination. 

Don't miss your chance to shape the future of crypto and create a legacy! Besides that, we also have some nice prizes.
