Complete playbook for building on Base L2 — network setup, smart contracts, wallet auth, payments, developer tool attribution, and framework migrations.
| Layer | Default |
|---|---|
| Network | Base Mainnet (8453) / Base Sepolia testnet (84532) |
| Contracts | Foundry (forge create + BaseScan verification) |
| Wallet auth | Base Account SDK (@base-org/account) |
| Payments | Base Pay — USDC, gasless, settles in <2s |
| Transactions | wagmi + viem |
| Attribution | Builder Codes — ERC-8021 via ox/erc8021 |
| RPC (prod) | Dedicated node provider or self-hosted Reth |

Complete Base development playbook. Covers: (1) Network — Base RPC URLs, chain IDs (8453/84532), explorer config, testnet setup, connect to Base, Base Sepolia; (2) Contracts — Foundry deployment, forge create, BaseScan verification, CDP faucet, testnet ETH, deploy contract to Base; (3) Builder Codes — ERC-8021 attribution suffix, referral fees, dataSuffix for Wagmi/Viem/Privy/ ethers.js/window.ethereum, transaction attribution, earn referral fees, append builder code; (4) Base Account SDK — Sign in with Base (SIWB), Base Pay, USDC payments, paymasters, gas sponsorship, sub-accounts, spend permissions, prolinks, batch transactions, smart wallet, payment link, recurring subscription; (5) Agent registration — trading bots, AI agents, automated senders, ERC-8021 attribution wiring, base.dev API, register agent, builder code registration; (6) Node operation — run Base node, Reth setup, hardware requirements, self-hosted RPC, sync; (7) Migrations — migrate OnchainKit, OnchainKitProvider to WagmiProvider, wagmi migration, remove onchainkit dependency, MiniKit to Farcaster SDK, convert miniapp, Farcaster miniapp to regular app, convert Farcaster miniapp.
