Base Wallet Toolkit

Wraps Base mainnet RPC calls into seven read-only tools for wallet inspection and transaction planning. You get balance checks across ETH and ERC-20s, gas estimates, token metadata lookups, allowance verification, ENS resolution, and transaction status queries. No API keys needed since it hits public Base RPC endpoints. Useful when you're building agents that need to check portfolio state, verify approvals before swaps, monitor gas costs, or confirm transaction outcomes on Base. Runs via npx with zero config, though you can point it at custom RPC providers through environment variables if you want rate limit headroom or specific node features.
