The Base Account SDK connects your app to the onchain accounts that power the Base App — over one hundred thousand users with a passkey-backed Smart Wallet. Add sign-in and USDC payments in a few lines; users hold their own keys and you never touch private data or funds.

Universal Sign-In

One passkey works across every Base-enabled app — no installs, seed phrases, or network switches.

One-Tap Payments

A single pay() call handles gas and USDC settlement.

Base Verify

Prove verified account ownership and add Sybil-resistant identity checks.

Recurring Payments

Create and charge USDC subscriptions with the Base Account SDK.
