Stellar Agent Guard

Appearance

SDK — Overview ​

The stellar-agent-guard-sdk repository provides the TypeScript integration bridge between AI agent frameworks (LangChain, ElizaOS) and Stellar Agent Guard smart accounts.

🎯 What it Does ​

  • Pre-flight Policy Interception: Simulates agent contract calls against the on-chain Soroban RPC before broadcast, preventing policy-violating transactions from ever hitting the network or spending fees.
  • Zero-Broadcast Cost Pre-checking: Calculates inclusion and resource fees directly from simulation responses, enforcing spend ceilings before signing.
  • Agent Transaction Assembly & Signing: Merges required contract footprint keys and signs custom account auth entries with the agent's keypair.
  • Dual-Stream Telemetry: Monitors both uncommitted refusal events (event_auth_checked from simulation diagnostics) and committed ledger events.
  • Framework Middleware: Plug-and-play middleware adapters for LangChain tools and ElizaOS action validators.
