This is the official Stellar skill, and it's clearly built for serious blockchain work. It covers the full stack: Soroban smart contracts in Rust, dApp frontends in React/Next.js, wallet integrations like Freighter, and transaction handling across Stellar's SDKs. What's interesting is the inclusion of agentic payment protocols (x402, MPP) and privacy features like zero-knowledge proofs, which suggests it's aimed at developers building the next generation of financial applications, not just basic token transfers. With 158 installs and passing most security audits (Snyk shows a warning), it's a real tool being used in production. If you're building on Stellar or evaluating it against other L1s, this gives Claude the context it needs to actually help.
