Provides institutional-grade platforms for the issuance and management of digital securities and tokenized real-world assets, serving large financial institutions in a SaaS/PaaS model. Co-authored Stellar's CAP-35 (asset clawback) feature and works closely with the Stellar Development Foundation.

Securitize

Securitize is the world's largest tokenization platform, unlocking broader access to alternative investments by enabling private businesses to raise capital from investors while providing liquidity. With $4B+ in assets across products including BUIDL, USDtb, and VBILL, it is backed by BlackRock and Morgan Stanley.

Scaffold Stellar

Scaffold Stellar is a developer boilerplate and framework for building dApps on the Stellar network. It provides built-in OpenZeppelin smart contracts, a frontend scaffold, contract invocation tooling, and CLI plugins — enabling developers to go from zero to testnet in minutes.

Sava

Turkey has one of the highest crypto adoption rates in the world, over 25% of the population owns crypto, roughly 25M people and $200B+ in annual transactions. The Lira lost over 80% of its value against the dollar in 5 years, with inflation above 40%. Bank deposit rates don't keep up, so savings lose value every month. Millions already convert lira to stablecoins through exchanges like BtcTurk and Binance TR, but the process is fragmented, buy USDC on an exchange, move to a wallet, find a protocol, manage seed phrases. Most stop at the exchange and miss out on any returns. Sava removes that complexity. A non-custodial savings app built on Stellar where Turkish users deposit Lira, earn returns on USDC through Blend Protocol lending pools, and see everything in ₺. Users sign in with email — Privy creates a self-custodial Stellar wallet automatically, no seed phrases needed. Mercuryo handles TRY-to-USDC conversion inside the app. The experience is a savings account, not a DeFi dashboard. Turkey has zero Stellar-based consumer products today. Sava is the first.

Rumble Fish

A software development house specialising in blockchain, DeFi, and AWS cloud. Active in the Stellar and Soroban ecosystem, Rumble Fish built a Soroban-first block explorer and a Prices API for the network, and is also the creator of the Deva Wallet.

Renesis

Portfolio management and order execution system for institutional investors accessing Stellar DeFi and RWA ecosystem.

Rehive

A white-label fintech platform — the 'Shopify for fintech' — that enables founders to build, launch, and scale compliant financial apps without building from scratch. Built on Stellar, it provides modular ledger, user management, payments, currency conversion, and wallet infrastructure so early-stage fintechs, marketplaces, and anchors can go to market in weeks rather than months.

RedSwan

RedSwan is a FINRA-regulated digital securities marketplace that tokenizes real-world assets (RWAs) on Stellar, focused on commercial real estate. It has issued over $100M of institutional-grade multifamily and hospitality properties, enabling fractional ownership with lower minimums and 24/7 secondary-market liquidity.

Piggy Wallet

Piggy is a global family finance app that helps kids learn to save, earn, and grow money through gamified chores, savings goals, and parent-approved rewards. Parents keep full control (permissions, limits, approvals), while kids get a simple, motivating experience that builds real money habits. Piggy is designed to be a borderless wealth-building account for Gen Alpha, using stablecoins as the foundation for low-friction deposits, transparent balances, and (optional) yield-powered savings, while keeping the product UX-first and family-safe.

PG Atlas

PG Atlas is the objective, transparent metrics backbone for the SCF Public Goods Maintenance program. Its primary role is to shift public goods funding decisions from noisy, subjective signals to verifiable, data-driven insights by quantifying adoption, criticality, reliability, security/quality, and decentralization (risk) across open-source tools, libraries, explorers, RPC infrastructure, SDKs, and other foundational components in the Stellar/Soroban ecosystem. By providing a live dependency graph, transitive impact scoring, pony factor analysis, and an active subgraph projection, PG Atlas directly powers the Metric Gate in the proposed funding decision stack and supplies off-chain context for NQG-weighted voting in the community-led Public Goods decentralization pilot.

Paywit

Paywit is a wallet-agnostic payment layer enabling merchants to accept stablecoin payments on Stellar without integrating individual wallets or managing blockchain complexity. It provides hosted checkout and drop-in SDKs that abstract wallet complexity — merchants integrate once, users pay from any Stellar wallet via SEP-7, and funds settle directly to merchant wallets (fully non-custodial). Paywit verifies payments via Horizon and notifies merchants instantly.

PagFinance

BRLP is a regulated BRL settlement token issued on Stellar for institutional FX, institutional payments, and crypto-to-fiat reconciliation. Tokens are minted only after BRL is received in a regulated account, transferred exclusively between authorized institutional counterparts, and burned on exit — on-chain supply always matches real-world custody. PagFinance replaces bilateral reconciliation and delayed settlement with near-instant finality, deterministic auditability, and compliance-by-design, connecting Brazilian banking rails to modern on-chain coordination using Stellar's native asset controls.

Orion

A unified, semantic API that computes and serves a user's total DeFi exposure across major Soroban protocols. The service ingests protocol state (Blend, Aquarius, Soroswap, FxDAO), normalizes positions into financial primitives (deposits, borrows, LP exposure, debt, yields), computes derived metrics (net exposure, health factor, risk signals), and provides real-time and historical position data via a performant REST interface. Orion enables wallets, dashboards, analytics tools, and risk engines to build consistent, accurate DeFi user experiences without reimplementing protocol logic.

Ondo

Ondo Finance issues USDY on Stellar, a yield-bearing tokenized US-dollar token backed by short-term US Treasuries and bank deposits. Launched on Stellar in 2025, USDY provides an interest-accruing dollar asset (a yield-bearing alternative to fiat stablecoins) for onchain savings, treasury, collateral, and cross-border payment flows. Trades above $1 as yield accrues.
