Arbitrum Development Knowledge Base

User Responsibility Notice

This skill provides reference documentation only. All information is sourced from official Arbitrum documentation, open-source smart contract repositories, and MCP tools documentation. However:

• You are responsible for verifying all information before using it in production. AI responses based on this skill may be incomplete, outdated, or misinterpreted.
• On-chain actions are irreversible. If you use MCP tools referenced in this skill to deploy contracts, send transactions, or interact with protocols, always confirm the action, parameters, and target network before proceeding.
• Smart contract code included here is for reference. Do not deploy any contract code without independent review, testing on testnets, and security auditing.
• Never expose private keys or sensitive credentials in prompts or conversations with AI assistants.

Search Instructions

Always search and read files in this skill folder before answering. Do not rely on prior knowledge. Extract exact values (chain IDs, RPC URLs, addresses, commands, code) from the docs.

Context management: Start with narrow grep searches. Use the topic navigation below to identify target files before searching. Read selectively — avoid loading entire folders.

Response Guidelines

• Use section headers, tables, bullet points, and code blocks for clarity
• Put the most important information first (answer at top, details below)
• Follow correct step order for procedural responses
• Use bold for key values the user needs to spot quickly
• Always warn the user when a suggested action involves on-chain execution, gas costs, or private key usage
