Stellar Development Skill

A comprehensive AI skill for modern Stellar development with current best practices. https://skills.stellar.org/

Inspired by solana-foundation/solana-dev-skill and cloudflare/skills.

[!NOTE] This skill was AI-generated using Claude Code and is currently under manual review. We welcome contributions! Please submit PRs, open issues, or provide feedback to help improve this resource for the Stellar ecosystem.

Overview

This skill provides AI assistants with deep knowledge of the current Stellar development ecosystem:

• Smart Contracts: Soroban (Rust SDK, WebAssembly)
• Client SDKs: stellar-sdk (JavaScript), Python, Go, Rust
• APIs: Stellar RPC (preferred), Horizon (legacy)
• Assets: Stellar Assets, Stellar Asset Contract (SAC)
• Wallets: Freighter, Stellar Wallets Kit, Smart Accounts (passkeys)
• Testing: Local Quickstart, Testnet, Unit tests
• Security: Soroban-specific patterns, audit checklists
• Ecosystem: DeFi protocols, developer tools, community projects

Installing

These skills work with any agent that supports the Agent Skills standard.

Skill Structure

├── soroban/SKILL.md           # Soroban contracts + testing + security + patterns + pitfalls
├── dapp/SKILL.md              # Frontend, wallets (Freighter, Wallets Kit), signing, smart accounts
├── assets/SKILL.md            # Stellar Assets, trustlines, SAC bridge
├── data/SKILL.md              # Stellar RPC (preferred) + Horizon (legacy), indexing
├── agentic-payments/SKILL.md  # x402 + MPP (Charge + Channel) for AI/machine payments
├── zk-proofs/SKILL.md         # ZK verification, BLS12-381, BN254/Poseidon (status-sensitive)
└── standards/SKILL.md         # SEPs, CAPs, ecosystem projects, curated reference links

Each sub-skill is a self-contained Agent Skill with its own frontmatter. Cross-references link related skills (e.g., the agentic-payments skill points to soroban for the Soroban SACs the protocols call, and to assets for USDC). The AI reads only the sub-skills relevant to the task at hand.

Example Prompts

"Help me write a Soroban smart contract for a token"
"Set up a Next.js app with Freighter wallet connection"
"How do I deploy a contract to Stellar Testnet?"
"Create unit tests for my Soroban contract"
"Review this contract for security issues"
