Stellar Builder Summit Sao Paulo: 12 winners announced across 6 tracks including confidential tokens, enterprise RWA escrow, regional on-ramp kits, emerging market yield, agentic payment discovery, and CLI tooling. 190 developers built for 8 consecutive days, delivering products spanning privacy, institutional infrastructure, and local payments.

Three developers from Kolkata transition from hackathon wins to shipping production. Sachindra, Shomadeep, and Orko discuss how mentorship, team collaboration, and obsessive focus on security move projects beyond demos to mainnet. Their lesson: solo builders often stall; teams that emphasize production-readiness from day one ship live products.

Philippine developers Carl (Velo), Mark (Treasure), and Armie share their Web3 onboarding journeys and APAC Hackathon experience in a Rise In Builder Spotlight. They discuss how community support, mentorship, and hands-on hackathons helped them shift from blockchain skepticism to building live projects on Stellar.

The APAC Stellar Hackathon Grand Finale brought 30 finalists from Philippines, Indonesia, and Vietnam to pitch projects across three tracks—local finance, DeFi, and payments—competing for $60,000 in prizes.

Stellar's Q2 milestone: $3 billion in real-world assets, marking institutional adoption from both the financial infrastructure layer (DTCC selecting Stellar for tokenization) and the access-constrained end (MoneyGram launching MGUSD for 60 million customers). Developer ecosystem reached 2,968 active monthly builders, now the second-largest by developer count.

Vietnamese developers Andre, Ken, and Luis built Nexus, a peer-to-peer lending platform on Stellar, during APAC Hackathon. Unlike pooled lending models, Nexus lets borrowers and lenders negotiate custom terms directly on-chain using smart contracts for collateral management and repayment.

Pebriansyah went from crypto educator in Indonesia to founder of ORBIT Protocol on Stellar. He won three hackathons learning that go-to-market strategy matters as much as code, and now mentors hundreds of builders via webcoding.id.

Stellar Raven, an MCP (Model Context Protocol) server, ensures AI agents have accurate Stellar knowledge. Introduced at the Stellar Developers Meeting, the tool aggregates documentation, ecosystem data, and verified sources to prevent LLM hallucination when building on Stellar.

GrantFox community call #2 provides a comprehensive walkthrough of the platform's open-source contribution workflow. Covers the maintainer side: project onboarding approval criteria, repository linking and campaign registration, and detailed issue creation. Also demonstrates the contributor experience: application system with tier metrics, reputation tracking, and a newly-requested withdrawal feature to prevent stalled applications from blocking slots.

DeFindex co-founders Francisco, Esteban, and Joaquin discuss their path from France to Stellar blockchain, building the first smart contract protocol (Sorsa), and their vision for AI agents handling money through blockchain infrastructure.

Ahmed, an international climber and developer from Yemen, shares his journey into Web3 through Istanbul's Y2 Blockchain club and work at early-stage startups. Now at Synchronicity building AI-powered trading strategies, he advocates for hackathons over traditional job applications as the path to Web3 opportunities.

OpenZeppelin released confidential tokens as a developer preview on Stellar testnet. The feature enables private transfer amounts and balances while keeping counterparty addresses visible. Designed for private payroll, grants, treasury management, and B2B settlement. Mainnet launch expected late summer after security audit.

SDF senior technical writer Brie Wilde demonstrates Quarterly Ascension, an on-chain game where ten autonomous AI middle managers compete for a single VP promotion. Agents transact via Soroban smart contracts and MPP. Players direct their agents through 'life coaching' or let them act autonomously. The game showcases what developers can build with advanced Stellar infrastructure.

Stellar's RWA market cap exceeded $3 billion. This week's developer meeting features Gaian, a Southeast Asia payment infrastructure startup that uses USDC on Stellar to connect crypto wallets directly to local banking rails, enabling merchant payments and cross-border transfers that settle into real bank accounts. Gaian demonstrated their V2 API and self-serve onboarding dashboard.

Milan, 20, is building orbitkit.fun, a CLI tool that lets developers scaffold entire Stellar apps with one command. Winner of Best AI Dev Tool at Stellar Build residency, the tool addresses a core friction point: new builders arriving at Stellar face doc-heavy onboarding. Currently at 7,200 users, Milan is also running a web agency doing $12k MRR while studying engineering and working full-time.

Three builders discuss how Stellar Light, Stellar Passport, and Lumen Loop work together to solve the ecosystem's core visibility problem: new developers struggle to find projects and prove their contributions. The three tools form a complementary stack addressing onboarding, participation tracking, and signal aggregation.

Two Costa Rican students, Sebastian and Daniel, are building ACTA, an identity and verifiable credentials layer for Stellar. The team recently secured SDF funding to develop a native decentralized identifier (DID) for the network, addressing critical infrastructure Stellar lacked. Mainnet live since January, ACTA offers API, SDK, and DApp interfaces, with real clients already using the platform for credential issuance and verification.

Alejandro from Bolivia discusses building Polar, infrastructure for onboarding developers to Stellar. He shares his journey from economic crisis to blockchain adoption, and his philosophy of building for people in emerging markets.

Two Indian developers, Surya and Saindipal, discovered Web3 through Ryzen's Kolkata hackathon community and won an Aptos competition with ZeroMove, an IDE for smart contract deployment that scaled to 3,000+ monthly users. They're now building on Stellar.

Introduction to Stellar Journey to Mastery 2.0, a 7-level learning program for building on Stellar. Video covers dashboard access, program structure, idea submission requirements, and how to navigate the progression from beginner to master builder track.

GrantFox community call walks through the redesigned open-source contribution platform on Stellar. Founders showcase new UI updates, a dual-sided rating system for contributors and maintainers, and a flagging mechanism with strikes to maintain code quality.

SDF's SoroPG Academy teaches AI-assisted Soroban smart contract development with human control at the center. The lesson: establish a baseline, ask AI for one narrow testable change, review the code, run tests, and only deploy once you fully understand the result. AI accelerates development without replacing developer responsibility.

Winners from the 2026 Istanbul Build On Stellar x RiseIn Hackathon discuss why they chose Stellar for their first blockchain projects. They praise the network's ease of use, developer-friendly architecture, and fast transaction settlement. The winners highlight how AI tools like Claude and Cursor accelerated their development process, and emphasize the importance of judge feedback for refining their ideas.

Stellar Philippines is establishing a builder-focused developer ecosystem in the island nation through university bootcamps, hackathons like the ongoing IPAC event, and developer bounties. Led by country lead Nelson Lumbres and tech lead Armelin Obingar, the initiative draws from their prior success building ICP Philippines into a community of thousands of developers. Rather than chasing speculative investment, they emphasize building technology infrastructure during market downturns—positioning Philippine developers for first-mover advantage.
