build-on-base

Base Development

Complete playbook for building on Base L2 — network setup, smart contracts, developer tool attribution, agent registration, and node operation.

Default Stack

Safety Guardrails

• Never commit private keys — use cast wallet import for Foundry keystores
• Never expose RPC API keys or CDP credentials client-side — proxy through backend
• Never send transactions without Builder Code attribution — silent data loss, no errors, no warnings
• Validate all user-provided shell inputs before constructing forge/cast commands (no spaces, semicolons, pipes)

Task Routing

Read the reference for your task:

Operating Procedure

1. Classify the task using the table above
2. Read the relevant reference before implementing
3. Confirm the framework with the user when multiple options exist (e.g., Privy vs wagmi for Builder Codes)
4. Implement with explicit chain ID, security requirements, and all required validations
5. Deliver diffs, install commands, and any manual steps (env vars, API key setup, wallet registration)
