FAQPage Schema
How do I add Sign in with Base (SIWB) for passwordless authentication?▼

You can accept USDC payments by integrating Base Pay through the Base Account SDK. This enables one-tap USDC transactions, allowing your decentralized application to process payments directly from users' smart wallets.

How do I set up a paymaster for gas sponsorship on Base?▼

Setting up a paymaster for gas sponsorship involves using the Base Account SDK to configure smart wallet features. This allows your application to sponsor transaction fees, enabling gasless transactions for users interacting onchain on Base.

Can I create sub accounts and spend permissions with a Base smart wallet?▼

Yes, the Base Account SDK supports creating sub accounts and configuring spend permissions within your smart wallet. This enables recurring subscriptions and controlled token spending limits for individual users.

What are Prolinks and how do I generate shareable payment links?▼

Prolinks are shareable payment links generated via the Base Account SDK. They allow you to facilitate USDC payments by sharing a URL, enabling recipients to execute one-tap transactions directly through Base Pay.

Does the Base Account SDK support batching multiple onchain transactions?▼

Yes, the Base Account SDK supports batch transactions for smart wallet interactions. This allows your application to group multiple onchain operations into a single transaction, reducing user friction and optimizing gas costs.
