Stellar Smart Contracts

Write, test, secure, and ship Rust smart contracts on Stellar. Covers patterns, pitfalls, and architecture.

Frontend & Wallets

Build Stellar dApps with the JavaScript SDK, Freighter, Wallets Kit, and passkey smart accounts.

Stellar Assets & SAC

Issue and manage classic Stellar assets and trustlines, with the SAC bridge for smart contract interop.

RPC & Horizon APIs

Query Stellar chain data with RPC (preferred) and Horizon (legacy). Covers streaming, indexing, and migration.

Agent Payments (x402 + MPP)

Charge AI agents for API calls with x402 paywalls or MPP payment channels.

ZK Proofs

Verify Groth16 proofs on-chain via BLS12-381, with Circom, Noir, and RISC Zero toolchain walkthroughs.

SEPs, CAPs & Ecosystem

Pick the right SEP or CAP for your feature, with ecosystem projects, curated reference links, and MCPs.

Cross-Chain (CCTP, Axelar)

Bridge native USDC with Circle CCTP, pass messages and tokens with Axelar GMP/ITS, and route intent-based swaps with NEAR Intents.

Community skills

Skills built and maintained by members of the Stellar community. Each project has its own install instructions; follow the link on a card to set it up with your agent.

Community skills are independently developed and are not reviewed, endorsed, or maintained by the Stellar Development Foundation. Inclusion in this directory does not imply any warranty, security audit, or recommendation by SDF. You are solely responsible for evaluating any community skill before use, including reviewing its code, license, and security practices.

OpenZeppelin Contracts

Scaffold a Stellar smart contract project with OpenZeppelin's audited Stellar contract libraries. Walks through Rust toolchain setup, Stellar CLI install, workspace dependencies, and applying the pausable and ownable macros to your contract.

DeFindex SDK

Integrate DeFindex vaults on Stellar with the @defindex/sdk TypeScript package. Covers vault deposits and withdrawals, balance and APY queries, programmatic vault creation, and the unsigned-XDR signing pattern for backend and bot integrations.

Soroswap SDK

Trade on Soroswap DEX from a backend, bot, or swap widget using the @soroswap/sdk TypeScript package. Covers token swaps, liquidity pool operations, price and route queries, API key handling, and signing flows for both server keypairs and browser wallets.

Trustless Work Escrow

Build escrow and milestone-based payment workflows on Stellar with the Trustless Work platform. Covers single-release and multi-release escrows, trustline configuration, dispute handling, and three integration paths: REST API, React SDK hooks, and pre-built Blocks UI components.

Agent Browser WebAuthn

Drive passkey and Stellar smart account browser tests with agent-browser and Chrome DevTools virtual WebAuthn authenticators.

Anchors

Integrate with or build Stellar anchors (fiat on/off-ramps, deposits/withdrawals, KYC). Covers core SEP flows (1/6/10/12/24/31/38) and common integration pitfalls.

PRISM Bounded Agent Treasury

Give an AI agent a non-custodial, contract-bounded spending account on Stellar with PRISM. Covers treasury deployment with per-payment and rolling daily limits, payee whitelists, time-bound agent session keys, escrow, x402-gated payments, and Groth16/BN254 ZK compliance proofs verified on-chain.

ROZO Intents

Send USDC and USDT across Stellar, Ethereum, Arbitrum, Base, BSC, Polygon, and Solana using natural language. Covers cross-chain bridging, wallet detection, fee estimation, tiered confirmation logic, and QR code payment parsing inside Claude Code.

Sozu Testnet USDC Faucet

Claim Circle USDC on Stellar testnet with a PoW-gated CLI, using an existing C…/G… address or a newly generated G… wallet with a USDC trustline.

LumenLoop MCP Connect

Connect any MCP client (Claude, ChatGPT, Gemini, Cursor) to LumenLoop's free read-only Stellar ecosystem MCP and learn its query tools for directory, content, and SCF data.

SCF Submission Radar

Position a Stellar Community Fund idea against prior submissions before applying: find similar past proposals, check what's been funded in an area, and sharpen positioning.

Stellar Builder Quickstart

Go from a Stellar product idea to a build path: pick the right primitives, check ecosystem prior art via LumenLoop, and route to the relevant build skill.

Stellar Content Auditor

Audit draft posts and announcements against Stellar ecosystem data: resolve project names and X handles, pull supporting citations, and flag unsupported claims.

Stellar Ecosystem Digest

Produce a dated, cited digest of recent Stellar ecosystem activity on a theme or entity from indexed news, talks, events, and research.

Stellar Ecosystem Scout

Map a sector of the Stellar ecosystem into a landscape of projects, categories, and regions using the LumenLoop directory and semantic search.

Stellar Integration Finder

Find the right existing Stellar project or tool to integrate (wallet, oracle, anchor, DEX, indexer) via the LumenLoop directory, then route to the matching build skill.

Stellar Project Dossier

Build a due-diligence profile of a single Stellar project: details, related content, talks, SCF history, and similar projects from the LumenLoop directory.

Stellar Scout

Scout the Stellar ecosystem before you build: validate ideas against shipped projects, match open SCF-funded RFPs, draft SCF pitches, find audit firms, and pull cited prior art from 2,000+ indexed repos.
