Stellar Development Skill (Soroban-first)
What this Skill is for
Use this Skill when the user asks for:
- Soroban smart contract development (Rust)
- Stellar dApp frontend work (React / Next.js / Node.js)
- Wallet connection + signing flows (Freighter, etc.)
- Transaction building / sending / confirmation
- Stellar Asset issuance and management
- Client SDK usage (JavaScript, Python, Go, Rust)
- Zero-knowledge proof verification (where supported by target network/protocol)
- Privacy-preserving applications (privacy pools, confidential tokens)
- Local testing and deployment
- Security hardening and audit-style reviews
- Agentic payments: paid APIs (x402) and AI agent payment clients (x402, MPP charge, MPP channel)
More from stellar/stellar-dev-skill
soroban
Soroban smart contract development on Stellar (Rust SDK). Covers project setup, contract structure, storage types, authorization, cross-contract calls, events, error handling, testing (unit, integration, fuzz, property, mutation, fork, differential), security patterns and vulnerability classes, advanced architecture patterns (upgrades, factories, governance, DeFi primitives), and common pitfalls. Use when writing, testing, securing, or shipping Soroban contracts.
5standards
Stellar standards, ecosystem, and reference. Covers SEPs (Stellar Ecosystem Proposals), CAPs (Core Advancement Proposals), and a quick map for picking the right standard for wallets, anchors, payments, deposits/withdrawals, federation, deep links, and KYC. Also bundles ecosystem references (DeFi protocols, dev tools, wallets, infra, community projects) and curated documentation links. Use when you need to know which SEP applies, or want a starting point for ecosystem integrations and official docs.
5data
Querying Stellar chain data via Stellar RPC (preferred) and Horizon (legacy). Covers RPC JSON-RPC methods, Horizon REST endpoints, streaming, pagination, historical queries, Hubble/Galexie for deep history, and the RPC/Horizon migration story. Use when reading balances, transactions, operations, ledgers, contract events, or building any indexer/analytics workflow.
4dapp
Stellar dApp / frontend development. Covers the JavaScript stellar-sdk (browser + Node.js), Freighter wallet, Stellar Wallets Kit (multi-wallet), Wallet Standard, smart accounts with passkeys, transaction building / signing / submission, Soroban contract invocation from the client, simulation, and error handling. Use when building a React/Next.js/Node.js app that talks to Stellar or Soroban.
4assets
Stellar Assets (classic) + trustlines + Stellar Asset Contract (SAC) bridge to Soroban. Covers asset issuance, distribution, authorization flags, clawback, regulated assets, trustline management, and the SAC interop layer that exposes classic assets as Soroban tokens. Use when tokenizing real-world assets, issuing stablecoins, managing trustlines, or bridging classic assets to Soroban contracts.
3zk-proofs
Zero-knowledge cryptography and privacy patterns on Stellar/Soroban. Covers Groth16 verification, BLS12-381 (CAP-0059, available), BN254 + Poseidon host functions (CAP-0074/0075, status-sensitive), Noir / RISC Zero integration, privacy pools, confidential tokens, Merkle tree commitments, and status-sensitive guidance for protocol/SDK readiness. Use when building privacy-preserving applications or ZK-verifier contracts on Stellar.
