A trustworthy multi-agent runtime in Go

Lango 🐿️

A trustworthy multi-agent runtime in Go. Lango is a high-performance agent runtime that lets AI agents collaborate, learn, and operate autonomously — with built-in observability, security hardening, and an optional peer-to-peer economy layer.

Why Lango?

Most agent frameworks stop at tool-calling. Lango builds a trustworthy operational foundation — then optionally extends into a peer-to-peer economy:

  • Multi-Agent Orchestration — Hierarchical sub-agent teams with role-based delegation, P2P team coordination with conflict resolution strategies, and DAG-based workflow pipelines.
  • Production Observability — Token usage tracking, Prometheus metrics, OpenTelemetry tracing, health monitoring, alerting with webhook delivery, and audit logging.
  • Zero-Knowledge Security — ZK proofs (Plonk/Groth16) for handshake authentication and response attestation. Agents prove identity and output integrity without revealing internals. Hardware keyring and Cloud KMS support.
  • Knowledge as Currency — Self-learning knowledge graph, observational memory, and hybrid vector + graph RAG retrieval — agents that get smarter with every interaction can charge for their expertise.
  • Open Interoperability — A2A protocol for remote agent discovery, MCP integration for external tool servers, and multi-provider AI support (OpenAI, Anthropic, Gemini, Ollama).
  • Peer-to-Peer Agent Economy — Agents discover, authenticate, negotiate prices, and trade capabilities over libp2p with budget management, trust-based risk assessment, and dynamic pricing. No central hub. No vendor lock-in.
  • On-Chain Settlement — USDC payments on Base Sepolia testnet (chainId 84532) with EIP-3009 authorization, milestone-based escrow (Hub/Vault dual-mode), Foundry smart contracts, and a Security Sentinel that detects anomalies in real time.
  • Smart Accounts — ERC-7579 modular smart accounts (Safe-based) with ERC-4337 account abstraction, hierarchical session keys, gasless USDC transactions via paymaster, and on-chain spending limits.
  • Trust & Reputation — Every interaction builds a verifiable reputation score. Trusted peers get post-pay terms and price discounts; new peers prepay or use escrow.
