Inside dispatchInboundMessage: 8-level routing, MsgContext normalization, system prompt assembly, and pi-agent-core's double-loop state machine with steering and follow-ups.

We traced every function call from the moment a message hits the WebSocket to when the agent starts streaming. Here's the exact code path through 161 gateway files.

Part 3 covers OpenClaw's Docker sandbox, security audit system, code quality strengths and concerns, ecosystem risks, and our final assessment.

Part 2 of our code review covers OpenClaw's lazy-loaded skill system, hybrid vector+FTS memory, 70 agent tools, and the 20+ lifecycle plugin hooks.

We cloned OpenClaw and read the source. Part 1 covers the monorepo layout, the surprising pi-mono delegation, the gateway server, and the routing engine.

We built a cross-chain ERC20 token bridge using LayerZero V2. It moves BRG tokens across Ethereum, Arbitrum, Base, and Optimism — 12 directional pathways, all trustless, with multi-DVN verification. This post walks through the actual code. The full source is at github.com/gnuser/brg-bridge.

Architecture

Lock-and-Mint Model

The bridge uses LayerZero’s OFT (Omnichain Fungible Token) standard:

• Ethereum (home chain): BridgeOFTAdapter locks ERC20 tokens when bridging out, unlocks when bridging back.
• L2 chains: BridgeOFT mints synthetic tokens on receive, burns on send. No pre-minted supply.

Total supply is always conserved: locked on Ethereum = minted across L2s.
