About build-on-base

build-on-base is a development skill with task-specific guidance for building on Base, from network setup and contract deployment to agent registration and node operation. It provides a default stack and security checks for implementation work.

Key features

01Base network configuration
02Foundry contract deployment
03Builder Codes attribution
04AI agent registration
05Base node operation
06Security guardrails

Use cases

01Configure Base Mainnet or testnet
02Deploy and verify contracts
03Add ERC-8021 transaction attribution
04Register an AI agent wallet

Install

Copy the command and run it in a terminal.

Base Development

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

Default Stack

Layer	Default
Network	Base Mainnet (8453) / Base Sepolia testnet (84532)
Contracts	Foundry (`forge create` + BaseScan verification)
Transactions	wagmi + viem
Attribution	Builder Codes — ERC-8021 via `ox/erc8021`
RPC (prod)	Dedicated node provider or self-hosted Reth

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:

Task	When to Use	Reference
Network config	RPC URLs, chain IDs, explorer links, testnet setup	references/network.md
Deploy contracts	Foundry deployment, BaseScan verification, faucet	references/deploy-contracts.md
Run a Base node	Self-hosted RPC, Reth, hardware requirements	references/run-node.md
Builder Codes	Add ERC-8021 attribution to transactions	references/builder-codes/overview.md
Register AI agent/bot	Register wallet, get builder code, wire attribution	references/agents/register.md

Operating Procedure

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