Introducing SuperPay: Build Crypto Payments Fast with Coinbase Developer Platform

At Coinbase, we're committed to empowering developers to build seamless crypto-powered payment solutions. Today, we're excited to announce the release of SuperPay, our latest demo application built using Coinbase Developer Platform (CDP). SuperPay demonstrates how easy it is to create robust and frictionless crypto payments experiences.

Traditional payment systems come with their share of frustrations: high fees, slow settlement times, complex integrations, and limitations around microtransactions. Crypto-based payments offer a powerful alternative—low fees, instant settlement, easy international transactions, and the ability to handle payments of any size effortlessly.

SuperPay is designed to showcase exactly these capabilities. It provides developers and businesses with a clear reference on how to quickly build and deploy crypto payment solutions using Coinbase’s tools.

SuperPay highlights key CDP capabilities:

• Instant Crypto Transfers: Effortlessly send and receive cryptocurrencies.

• Easy Fiat-to-USDC Onramp: Quickly onboard users to crypto.

• Seamless Invoicing: Create, send, and track invoices intuitively.

• Flexible Payment Links: Generate single-use or recurring payment links ideal for donations or simple payment requests.

• Clear Transaction Tracking: Manage and view transaction histories at a glance.

The demo runs live on the Base Sepolia testnet, offering a safe, zero-risk environment for experimentation. You can also check out https://superpayapp.xyz.

• Fiat Onramp Integration: Enable users to purchase USDC quickly through integrated fiat solutions using Onramp APIs and SDKs.

• Real-time Transaction Notifications: Stay instantly updated on blockchain events through Webhooks.
