Developer Activity

Stellar Quickstart is an official SDF Docker image that runs a complete local Stellar development environment, bundling Stellar Core, Horizon, and RPC in local, testnet, and futurenet modes. It includes a Friendbot faucet at :8000/friendbot to fund new testnet or local accounts with test XLM, letting builders develop against a private network or testnet without external services. It is integrated with the Stellar CLI for starting and stopping containers.

Open-source router by Rozo for reaching paid MPP services from Stellar-funded clients through a stable API, live on mainnet.

Domain-specific formal specification language for Soroban smart contracts, enabling verifiable correctness proofs and automated security analysis.

Official SDF-maintained TypeScript Wallet SDK (@stellar/typescript-wallet-sdk) for building Stellar wallet apps fast. Wraps the JavaScript Stellar SDK to handle accounts, payments, key management, and anchor integration via SEPs (SEP-6, SEP-10, SEP-24, SEP-31). One of the four official Wallet SDK languages on developers.stellar.org.

The official SDF-maintained Rust SDK (soroban-sdk) for writing Stellar smart contracts that compile to Wasm and run on the Soroban runtime. The canonical contract SDK: data structures, storage access, crypto, cross-contract calls and a test harness. Published on crates.io as soroban-sdk.

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.

Open HTTP payment protocol (402 Payment Required) with native Stellar support through the @x402/stellar package — the standard used by most Stellar agent-payment projects for per-call USDC payments.

Dig is an AI-powered on-chain analytics and trading terminal for Stellar DeFi. It provides a unified dashboard to explore protocol metrics (TVL, volume, APY) across Blend, Aquarius, Soroswap, and DeFindex, aggregate multi-wallet portfolios, receive smart on-chain alerts, and execute non-custodial swaps, deposits, and rebalances directly from the interface.

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.

ACTA is a decentralized identity and verifiable credentials platform built on Stellar. It enables organizations and individuals to issue, share, and verify W3C-compliant credentials on-chain via Soroban smart contracts — no programming knowledge required. ACTA also implements the did:stellar DID method standard for portable, resolvable identity across the Stellar ecosystem.

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.

Spectra (by Perspective, spectra.finance) is an interest-rate derivatives protocol live on EVM chains — fixed-rate yield via Principal/Yield Tokens.

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.
