For Yield is building one of the first French MiCA-regulated DeFi yield products on Stellar. PSCA dossier filed with AMF April 2026, agrement targeted October 2026. EP simplifie license (ACPR L.522-11-1 CMF) filed in parallel; dual-licence setup unique in France. 50 HNW clients, ~€7-8M AUM. Why Stellar wins: 1 Regulated EU access layer Soroban DeFi lacks, routing EU capital into Blend v2, Aquarius, Soroswap via DeFindex (all on SCF Integration List). 2 EURC-first: deposits, fees, redemptions in EURC, driving Circle's Stellar adoption (aligned with SDF's 2026 EU push). 3 €25M Y1 to €100M Y3 of regulated EU capital (AMF-validated plan, profitable Y1 in every stress scenario). 4 Three open-source Soroban primitives (YieldVault, Performance Fee Module, EURC SAC wrapper) any EU operator can fork. 5 Built on 7 SCF Integration List components (DeFindex, Blend v2, Aquarius, Soroswap, Allbridge, DFNS, Stellar Wallets Kit), no new dependency. Distribution Day 1: 35,000+ subscribers via Crypto & Macro (Saturnin Paulet's Swiss media) and signed LOIs with French wealth managers (May 2026).

Jumpa is an automated payment platform designed to make cross-border transactions simple, fast, and accessible for users in emerging markets. Today, payments across regions like Africa, Francophone countries, and Southeast Asia are often slow, expensive, and difficult to use. Many people are excluded from modern financial systems due to lack of smartphones, language barriers, or complex banking interfaces. Jumpa solves this by enabling users to send and receive money seamlessly without needing a bank account or advanced devices. Through chat-based interfaces and USSD, Beyond payment, Jumpa also (partnered with companies) provides stable yield by letting users invest small amounts in tokenized real-world assets like commercial paper, offering more predictable returns than traditional DeFi (Aave) models. By combining accessible payments with real-world asset-backed investments, Jumpa helps users not only move money but also preserve and grow their wealth, especially in regions facing inflation and currency devaluation.

LumenWipe closes a Stellar account and recovers its locked XLM reserves. It handles every step automatically: signer normalization, data entry removal, DEX offer cancellation, LP withdrawal, DeFi position exits (Blend, Aquarius, Soroswap, Phoenix, FxDAO), asset conversion, trustline removal, and the final account merge. The project responds to the Account Demolisher RFP. It extends the public-domain stellar.expert/demolisher/public by Orbit Lens with the piece that tool lacks: full Soroban and DeFi parity. Any account with a Blend loan, an Aquarius LP position, or a Soroswap pair share cannot be closed with any existing tool today. All transactions are built and signed in the browser. The backend is read-only and stateless, never in the signing path. A transparent mediator account handles CEX destinations, since no major exchange supports ACCOUNT_MERGE. A read-only allowance inspector lets users revoke token approvals without closing their account. The classic wind-down runs on testnet and mainnet today.
