Malvin YeungSole Designer · End-to-end launch & ongoing maintenance
I was the only designer on Slingshot - owning the product end-to-end from first concept through App Store launch and every release after it. That meant the consumer-grade swap experience across 8+ chains, collapsing routing, slippage, and gas decisions into a single confident tap; the brand system and motion language that became Slingshot's identity in app stores; and the design system that kept quality consistent as the app shipped continuously through acquisition by Magic Eden.

These are the latest designs of the Slingshot App prior to its acquisition by Magic Eden, where I played a key role in the overall design efforts. Major updates included USDC abstraction, an interactive trade pullback animation, a new leaderboard, referral rewards, and a complete Discover section overhaul.
