Pushing Bitcoin’s Boundaries: Meet the Winners of the Stacks Buidl Battle
Product Updates and News
Apr 8, 2025
The Stacks Foundation’s Buidl Battle was more than a competition—it was a vibrant celebration of Bitcoin’s future, uniting over 100 builders from March 3–21, 2025, to redefine what’s possible on Stacks. This virtual event connected developers with investors, mentors, and the Stacks community through workshops, streamed sessions, and top-tier support. Following closely on the heels of the Nakamoto upgrade and sBTC launch, it sparked an overwhelming response—96 submissions, refined to 81 legitimate entries—prompting Adam Haun of the Stacks Foundation to say, “We had to adjust the timeline; it was electric.” Crowned in a tournament-style showdown by expert judges and community votes, the champions shared their stories of triumph on Leather Lounge Episode 46, aired April 1, 2025. Now, meet the visionaries shaping Bitcoin’s next chapter—and discover how Leather empowers you to join them.
PoXAgents: Bitcoin Meets Conversational AI
Imagine managing your Bitcoin wallet through a simple chat. That’s the promise of PoXAgents, developed by Nestor Campos from Chile. Named after Proof of Transfer (PoX)—Stacks’ consensus mechanism that secures the network by linking Bitcoin’s blockchain to Stacks—this ChatGPT-style interface lets users check balances, send STX or sBTC, and manage SIP10 tokens, all via natural language. “My family doesn’t understand crypto,” Campos explained. “The idea is to onboard people without explaining blockchain.” Set to integrate with platforms like Telegram and WhatsApp, PoXAgents makes Web3 approachable, with Leather providing the secure backbone for wallet connections.
Kulture.fun: A Cyber Temple for Memecoin Enthusiasts
For those who revel in crypto’s playful side, Kulture.fun, crafted by Apollo Stargate and Blackfoot Joe, transforms memecoins into a dynamic force within a liquid staking “cyber temple.” “We wanted to give people the ability to do something with these memecoins and create more cult around their cults,” Stargate shared on Leather Lounge, emphasizing a vision born from frustration with scams on other chains. He recounted how an earlier hackathon on Solana “got rugged” when organizers “blocked the Discord,” leaving participants vulnerable—a stark contrast to Stacks’ secure foundation. Built on Stacks’ smart contract capabilities, Kulture.fun uses token-gating to create a scam-resistant ecosystem: only holders of specific memecoins can stake and access rewards, sidelining spammers and bad actors common on less curated platforms like Telegram. This blend of fun and utility ensures a vibrant, trustworthy community, with Leather providing a secure wallet to join this Bitcoin-powered haven—free from rugs and chaos.
Bolt Protocol: Frictionless sBTC Transactions
Ronoel’s Bolt Protocol takes aim at a persistent onboarding challenge: transaction fees that stifle new users. “Users need STX to send sBTC, but they don’t have it,” he observed on Leather Lounge, pinpointing a friction point that often halts Bitcoin adoption in its tracks. His solution is elegantly simple—Bolt Protocol lets you pay dApp fees directly with sBTC and enables instant transfers between Bolt Wallets, all secured on the Stacks blockchain. “They can use it like a bank account,” Ronoel added, envisioning a world where newcomers receive sBTC and send it onward without wrestling with secondary tokens or complex setups. Outpacing the Lightning Network in speed and seamlessly integrated with Leather’s self-custody wallet, this innovation strips away barriers, making Bitcoin-native apps more accessible than ever for novices and seasoned users alike.
TruthChain: Verifying Trust in a Digital Age
In an era where AI-generated content and deepfakes blur reality, TruthChain by Arowolokehinde and Henry Agukwe delivers a decentralized lifeline for authenticity. Built on Stacks and leveraging IPFS for cost-effective, permanent storage, this platform empowers creators to register articles, images, or videos on-chain, generating a unique hash that proves ownership and integrity. “You can verify content instantly,” Henry explained on Leather Lounge, underscoring its immediacy in a world rife with misinformation. “We’re looking at creating APIs… to help link content into Web2 spaces,” he added, envisioning a bridge that brings blockchain-verified trust to mainstream platforms like Medium or search engines.
BigMarket.ai: AI-Powered Prediction Markets on Bitcoin
Imagine betting on tomorrow’s Bitcoin price—or even the weather—using your BTC, with AI making it effortless. That’s Antonio Meic’s BigMarket.ai, a Bitcoin-native prediction market where users wager on real-world outcomes in a decentralized, trillion-dollar arena. “From market creation to liquidity to forecasting, AI does the heavy lifting,” Antonio explained, as AI crafts questions like “Will BTC hit $100K by June?” and ensures there’s enough sBTC to trade, while forecasting trends faster than traditional platforms—hourly, not monthly. “We’re creating a global infrastructure for decentralized truth,” he said on Leather Lounge.
BitForward: Forward Contracts for the Bitcoin Era
Ishan Singh, an accounting major from New York, launched BitForward, introducing forward contracts—deals to buy or sell at a fixed price later—into Bitcoin’s DeFi realm. “You can long the US dollar against the euro using Bitcoin,” he shared on Leather Lounge (51:01), letting you bet on currency shifts, like the dollar rising by July, in a trillion-dollar-a-day forex market untouched by crypto. Unlike typical trades you can exit anytime, these lock in for a set time—say, 90 days—and become NFTs you can trade for added control. Trustless and decentralized, it skips banks for Bitcoin’s rules: “If your long position drops 100%, you’re liquidated… that’s how you keep it decentralized,” Singh explained (54:23)—meaning if your bet fails completely, the system auto-ends it, ensuring fairness without intermediaries.
Adam Haun’s Insights: Why Stacks Stands Out
Reflecting on the Buidl Battle, Adam Haun, Head of Community Programs at the Stacks Foundation, underscored relationships as the cornerstone of Stacks’ builder appeal. “We engage with ecosystems and developer networks globally,” he said. “We surround them with other builders so they can form relationships to make them want to stay,” he added. Builders feel the difference: Apollo Stargate called Stacks “fresh, friendly, and close to Bitcoin,” while Antonio Meic noted, “It’s ready for prime time—especially post-Nakamoto and sBTC.” Leather amplifies this vibrant ecosystem, delivering the most secure wallet to connect you to these trailblazing innovations.
