BCH-1 is the kind of initiative I’ve wanted to see in the Bitcoin Cash ecosystem for a long time 💚🚀 More builders entering the ecosystem. More real products being created. More momentum around building on BCH. What makes it even more exciting for me personally is seeing builders from Africa show up, participate, and actually build through this hackathon. That means a lot. This is how ecosystems grow not just with ideas, but with builders, products, support, and real execution. BCH-1 is a big win for Bitcoin Cash, and I really hope this is only the beginning. Let’s do more. Let’s support more builders. Let’s keep building Bitcoin Cash. 💚🚀 #BitcoinCash #BCH #BCH1 #BuildOnBCH #Crypto #Paysats @bch_nigeria @BCHAfrica

📊 BCH-1 Hackcelerator — Post-Phase 2 Update Phase 2 has concluded. Post-sprint acceleration is underway. By the numbers: • 255 registered builders across 6 continents • 188 members on Telegram chat • 53 projects advanced to Phase 2 submission • 28 projects deployed on $BCH during sprint • 82% shipped working prototypes or live demos • 9 winners selected, $31K distributed • 19 teams recognized with honourable mentions • 1,038 Twitter followers built from scratch • 47K+ social impressions, 4.9K views on winner announcement ─── 🚀 What's Happening Now BCH-1 doesn't stop at Phase 2. Most hackathons fail the moment prizes are distributed—momentum dies, teams scatter, prototypes collect dust. We designed BCH-1 to bridge the gap between "working prototype" and "fundable MVP," because that gap kills more good ideas than bad execution ever will. Right now: Winning teams are in individual MVP guidance sessions. Product positioning that makes sense for BCH's ecosystem structure. Post-Hackcelerator Support (Multi-Month): - Go-to-market strategy for MVP - Structured ecosystem introductions. - Fundraising pathway guidance from BCH-1 - Technical infrastructure support. - CashScript and CashTokens integration guidance, smart contract security review access, deployment support—whatever keeps teams moving instead of stuck. ─── 📈 Why This Matters The programmable era of Bitcoin Cash isn't theoretical anymore. We have proof. @nexopsbch shipped an AI-assisted CashScript IDE with a benchmarking system that's already live. @BCHcash_mint built a CashToken minting platform and is planning mainnet deployment. @intents_swap finalized the contract architecture for an intent-based DEX. @rabbitexp_bch is optimizing a BCH block explorer, and studying building infrastructure for $BCH Those are just the top-line winners. Nineteen other teams are in active development right now. The programmability layer works when builders have the right tools and support structure. We also proved something bigger: builder interest exists when pathways are clear. ─── 🔭 Looking Ahead (Subject to Time Hiccups) March-April: Completing support for winning teams and select high-potential projects. Focus: Business Intelligence. BCH-1 will expand visibility moves. Updates to BCH-1 website and resources. Plans to pivot BCH-1 to a full ecosystem pipeline layer for $BCH is being worked on. May: Connecting qualified projects with ecosystem funding sources. Polished projects will be presented at @bchbliss. ─── To the 255 builders who registered, the 53 teams who submitted, the 9 winners (@nexopsbch @BCHcash_mint @rabbitexp_bch @OPTNLabs @trustbch1 @tripfiapp @intents_swap @flowguard_ @FundTokens_Cash), and 19 honourable mentions, you're building the proof that Bitcoin Cash's programmable era is real. The pipeline is active. More updates as teams hit milestones. BCH-1 Team, March 2026

OPTNLabs, the world's first Bitcoin Covenants wallet powered by $BCH, has just launched PUBLIC infrastructure endpoints for Chipnet (BCH's testnet). This is a game-changer for builders - fast, reliable tools to develop, test, and ship apps on Bitcoin Cash without hassle. Here's what you get: ✅ Electrum server: For lightweight wallet interactions and blockchain access – electrum-chipnet.optnlabs.com ✅ Chaingraph: GraphQL API for querying BCH data efficiently – chaingraph.optnlabs.com/v1/graphql ✅BCMR: Bitcoin Cash Metadata Registry API for managing token and asset info – bcmr.optnlabs.com/api/ Perfect for devs experimenting with covenants, tokens, and more. Dive in and build the future of peer-to-peer cash! 💪 #BCH #DeFi #Web3

I asked clawdbot to teach itself a skill for the Cauldron API. This is using Claude Sonnet via @AskVenice

There are several explorers for #BitcoinCash, but CashTokens are often incomplete. To make things easier for our users, we built a simple explorer that brings these pieces together. bchexplorer.info lets you explore Bitcoin Cash blocks, transactions, and CashTokens, including their BCMR metadata, in one place. Check it out! bchexplorer.info
