A "point-of-sale" MVP integration that enables coffee shops and other physical merchants using Square POS to seamlessly accept USDC payments via Coinbase Wallet.
Visit Live SiteThe Challenge
Coinbase needed a "one-off" team to autonomously lead and build a bridge between traditional fintech hardware (Square) and on-chain payments, requiring the definition of tools and workflows to handle complex integrations without constant client oversight.
Our Solution
We led the engineering for the 12-week development cycle, building the core checkout flow that integrates the Square POS SDK with Coinbase Wallet to verify and process real-time USDC transactions.
Key Results
- MVP delivered ahead of timeline
- Square POS to Coinbase Wallet integration
- Successful handoff to Coinbase team
