build-on-base

Полный плейбук разработки на Base. Охватывает: (1) Сеть — URL-адреса RPC Base, идентификаторы цепочек (8453/84532), конфигурация обозревателя, настройка тестовой сети, подключение к Base, Base Sepolia;…

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)
