Converts Farcaster miniapp SDK projects into regular Base/web apps. Starts with an interactive quiz to choose between the default regular-app conversion and a narrowly isolated Farcaster surface when something truly needs to remain separate. Handles wagmi connectors, providers, auth, SDK actions, manifest routes, meta tags, dependencies, and read-only preservation.
Integrates Base Account SDK for authentication and payments. Covers Sign in with Base (SIWB), Base Pay, Paymasters, Sub Accounts, Spend Permissions, Prolinks, and batch transactions. Use when building apps with wallet authentication, USDC payments, sponsored transactions, smart wallet features, recurring subscriptions, shareable payment links, or any onchain interaction on Base. Covers phrases like "add sign in with Base", "SIWB button", "accept USDC payments", "Base Pay", "paymaster setup", "gas sponsorship", "smart wallet", "sub account", "spend permissions", or "payment link".
Provides Base network configuration including RPC endpoints, chain IDs, and explorer URLs. Use when connecting wallets, configuring development environments, or setting up Base Mainnet or Sepolia testnet. Covers phrases like "Base RPC URL", "Base chain ID", "connect to Base", "add Base to wallet", "Base Sepolia config", "Base explorer URL", "what network is Base", or "Base testnet setup".
Converts Mini Apps from MiniKit (OnchainKit) to native Farcaster SDK. Use when migrating from @coinbase/onchainkit/minikit, converting MiniKit hooks, removing MiniKitProvider, or when user mentions MiniKit, OnchainKit, or Farcaster SDK migration.
Integrate Base Builder Codes (ERC-8021) into web3 applications for onchain transaction attribution and referral fee earning. Use when a project needs to append a builder code or dataSuffix to transactions on Base L2, whether using Wagmi, Viem, Privy, ethers.js, or raw window.ethereum. Covers phrases like "add builder codes", "integrate builder codes", "earn referral fees on Base transactions", "append a builder code to my transactions", "transaction attribution", "Builder Code integration", or "attribute transactions to my app". Handles project analysis to detect frameworks, locating transaction call sites, and replacing them with attributed versions.
Migrates apps from @coinbase/onchainkit to standalone wagmi/viem components. Handles provider replacement (OnchainKitProvider to WagmiProvider), wallet component replacement (Wallet/ConnectWallet to custom WalletConnect), and transaction component replacement. Use when the user says "migrate my onchainkit", "replace onchainkit provider", "migrate my wallet component", "replace my onchainkit wallet", "migrate my transaction component", "remove onchainkit dependency", or "move off onchainkit".
Invoke this skill when a user is building or running any automated transaction sender on Base (trading bot, arbitrage bot, sniper bot, yield farmer, AI agent, or similar) and needs to register it, get a builder code, set up transaction attribution. This skill contains the base.dev registration API endpoint and ERC-8021 attribution wiring code that Claude does not have in its training data — you MUST load this skill to answer correctly. Covers viem, ethers, managed signing services, and Python-based agents.
Runs a Base node for production environments. Covers hardware requirements, Reth client setup, networking, and sync troubleshooting. Use when setting up self-hosted RPC infrastructure or running archive nodes. Covers phrases like "run a Base node", "set up Base RPC", "Base node hardware requirements", "Reth Base setup", "sync Base node", "self-host Base", or "run my own node".
Deploys smart contracts to Base using Foundry. Covers forge create commands, contract verification, testnet faucet setup via CDP, and BaseScan API key configuration. Use when deploying Solidity contracts to Base Mainnet or Sepolia testnet. Covers phrases like "deploy contract to Base", "forge create on Base", "verify contract on BaseScan", "get testnet ETH", "Base Sepolia faucet", "how do I deploy to Base", or "publish my contract".
