02 Mar - 20 Mar
Stacks is a Bitcoin Layer 2 network that brings smart contracts, decentralized applications, and programmable assets to Bitcoin. The BUIDL Battle #2, also known as The Bitcoin Builders Tournament, was a virtual hackathon hosted on DoraHacks focused on advancing the Stacks ecosystem. Running in March 2026, the event challenged developers to build innovative projects utilizing Clarity, sBTC, USDCx, and the x402 protocol. The tournament featured a $20,000 USD prize pool split between an open track and specific technological bounties. Over 400 developers registered, resulting in 140 approved projects that pushed the boundaries of Bitcoin-native assets and cross-chain liquidity.

How to join Stacks - BUIDL Battle #2?
To participate in the BUIDL Battle #2, developers needed to visit the official hackathon page on DoraHacks and register as a Hacker. Participants could join as individuals or form teams and designate a captain to coordinate their collaborative builds.
The core objective was to build an original decentralized application leveraging Stacks technologies. Developers were strongly encouraged to utilize Clarity smart contracts, sBTC integrations, USDCx, or the x402 protocol to align with the ecosystem's 2026 roadmap. Teams could submit their dApp to the main Open Track or target specific thematic bounties for additional prize opportunities.
Before the March 20, 2026 deadline, teams were required to finalize their submission via the DoraHacks portal. A complete and eligible submission required a working GitHub repository, a functional demo, and a pitch video explaining the project's utility and alignment with the Stacks ecosystem.
