Soroban Smart Contracts

End-to-end guide for building Soroban contracts: writing them, testing them, securing them, and shipping advanced architectures. This skill bundles five concerns that live and die together — the contract code, the tests, the security posture, the design patterns, and the gotchas.

When to use this skill

• Writing a Soroban contract in Rust
• Setting up unit, integration, fuzz, or property tests
• Reviewing a contract for security issues (authorization, reentrancy-adjacent bugs, storage hygiene, TTL, overflow)
• Architecting upgradeable contracts, factories, governance, or DeFi primitives
• Debugging a Soroban-specific error (auth, storage, archival, resource limits)
