Case Study
Base Mini App: One-Click, Gasless Mint on Base
A minimal, production-style app that showcases the full power of Base: EIP-5792 intents, Smart Wallets, and Paymaster-sponsored transactions. The result is a seamless, one-click mint that feels native to the web, not a wallet.
Feature Highlights
Single-Click Transactions (EIP-5792)
Complex actions such as minting and approvals are bundled behind one friendly action using the EIP-5792 standard for smart wallet intents.
Truly Gasless with Paymaster
Transactions are sponsored using the Coinbase Paymaster, letting users mint without holding crypto or seeing gas prompts.
Effortless & Secure Onboarding
Smart Wallet + Passkey login removes seed phrases and enables fast, secure authentication that feels like a normal web app.
Seamless Mint Flow
Optimized UI with optimistic updates and motion micro-interactions for a smooth, confidence-building onchain experience.
Technologies Used

Framer MotionUse Cases
- • Frictionless on-chain minting for marketing campaigns, POAP/POA drops, and event badges.
- • Starter templates for teams adopting EIP-5792, Smart Wallets, and Paymaster in Base apps.
- • Education and demos that onboard non-crypto users without requiring a wallet extension or funds.
Challenges & Learnings
Intents and Wallet Interop
Ensuring clean intent flows across browsers and devices while preserving one-click semantics and clear user feedback.
Passkey UX Edge Cases
Handling passkey registration/restore and fallback paths gracefully so first-time users never hit a dead end.
Sponsored Tx Observability
Adding telemetry around sponsorship outcomes, retries, and provider responses to keep the “gasless” promise reliable.
