A cross-network execution and liquidity system spanning 20 networks, including native Bitcoin and tokenized equities (xStocks). Wallets, DEXs, and lending protocols integrate SODAX to ship cross-network features faster and extend their reach to every network SODAX touches. SODAX is infrastructure for modern money.

Stellar Wallets Kit (by Creit Tech) is a single TypeScript library that handles integration with all major Stellar ecosystem wallets at once — xBull, Freighter, Albedo, Rabet, Ledger, Trezor, WalletConnect, HOT Wallet and more behind one interface, so dApps integrate every wallet without shipping per-wallet code. An INTEGRATION KIT for developers, not an end-user wallet product.

A minimal passkey SDK and drop-in create / sign / recover components for Stellar smart accounts, built to plug into stellar-wallets-kit. ES256-only, always low-S, proven on testnet.

Decentralized commodity trade finance platform that generates on-chain yield from asset-backed commodity financing trades. Pipeline targets the ~$2.5 trillion trade finance gap — widened by Basel III regulatory changes that made short-duration commodity-backed lending to mid-market traders uneconomic for banks — by providing institutional-grade rails for digital asset investors to access high, asset-backed yield with short duration (30–180 days). Built on Soroban/Stellar with institutional custody (BitGo), KYC/AML screening, and a 3-of-5 Risk Council multisig governance structure.

LumAgg is a liquidity aggregator for Stellar’s Soroban DEX ecosystem. It discovers prices across Soroswap, Aquarius (volatile, stable, and CLMM), Phoenix, Sushi V3, Comet, and Stellar Classic DEX, then returns the best route—including split execution across multiple venues in a single atomic swap.

MyDataCoin builds privacy-preserving DeFi lending and KYC compliance on Stellar using zero-knowledge proofs and self-sovereign identity, with an 'Atria' dashboard suite.

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.

Trustline unlocks institutional onchain finance. Hacks like Bybit on Ethereum and Drift on Solana are an urgent reminder that blockchain works, but isn't yet safe to use even for native users. Trustline is offering the missing security and insurance layer for institutional adoption. Since 2025, stablecoin adoption has enabled institutions to manage wallets and hold digital assets. They now seek institutional-grade yield. At the same time, proven onchain lending and trading protocols want institutional users, but their permissionless design and the $4B lost to fraud and hacks in 2025 remain major barriers. Trustline bridges this gap. It adds institutional access controls, stronger security standards, and smart contract insurance to any protocol. This helps onchain services offer a best-in-class approach to security and client fund protection, with insurance coverage if unforeseen events occur. Trustline supports asset managers and hedge funds, RWA issuers, and intermediaries or brokers matching institutional trading and lending flows. We've build a first live protected vault for algorithmic trading hedge fund on Hyperliquid, and this grant will support Trustline’s implementation on Stellar and Soroban, opening Stellar-based onchain services with institutional investors as NAV products.

Tokenized RWAs, such as funds, T-Bills or private credit products, are difficult to trade on traditional DEXs because they are regulated, fragmented and often include redemption periods. This lack of instant liquidity limits their use in DeFi, especially for lending market liquidations, margin calls or fast exits from a RWA into a stablecoin. Octarine solves this problem through RFQ-based auctions. When a user or protocol needs liquidity, selected liquidity providers compete to offer the best executable price. The winning LP takes the asset, waits for its redemption period and earns a premium, while the user receives immediate liquidity. Octarine can also accept bids from third-party protocols and structure dedicated liquidity facilities, increasing available depth and price quality without leaving capital idle. On Stellar, Octarine aims to deploy this liquidity layer for tokenized assets and enable faster and deeper secondary RWA markets.

Noether is a decentralized perpetual futures exchange built natively on Stellar/Soroban.
