Where should I go to actually create a wallet?

For a human getting started: Coinbase's Base App is the mainstream on-ramp — it's the old Coinbase Wallet rebuilt as a consumer app, live on the app stores, with passkey sign-in (no seed phrase required unless you want one), USDC that earns yield while it sits, and one-click USDC checkout. If you prefer alternatives, Phantom and Uniswap's mobile wallet are credible; if you're holding serious long-term value, a hardware wallet is still the right answer — app wallets are for spending money, not life savings. For an AI agent, it's different: agents use programmable wallets from developer platforms (Coinbase's CDP is the main one) where you set the spending policy and the agent operates inside it. One thing we won't do: walk you through entering keys or seed phrases anywhere — no legitimate service ever needs those, including us. Set the wallet up through the provider's own onboarding, fund it with USDC on Base, and you're equipped for everything x402 does.
