Industry: Web3 / NFTLocation: SingaporeDuration: 12 weeksTeam: 5 engineers

“A Web3 startup wanted to build a premium NFT marketplace for curated digital art. Competing platforms were crashing during drops and had terrible onboarding. We built a marketplace that handles high concurrent traffic smoothly, with gasless minting and credit card payments to bring in mainstream users.”

The Problem

What Was Going Wrong

The client needed to launch an NFT marketplace that stood apart from competitors plagued by scalability issues, high gas fees, and complex onboarding. They wanted both crypto-native users and mainstream art collectors to feel at home — and had a tight launch deadline.

Competitor platforms crashing during popular drops — losing creator trust

High gas fees making smaller NFTs economically unviable

Complex wallet-based onboarding scaring away mainstream users

No cross-chain support — creators locked into one ecosystem

Tight launch timeline with investors already announcing the date

The Solution

What We Built

We built a Layer 2-first marketplace with gasless minting, credit card payments, and a custodial wallet option for mainstream users — while keeping full Web3 capabilities for crypto-native users.

Layer 2 deployment with Ethereum bridge for high-value collections

Gasless minting via meta-transactions — zero cost for creators to list

Fiat on-ramp with credit card purchases — no wallet required for buyers

Auto-scaling infrastructure for handling high concurrent traffic during drops

“Our first major drop had thousands of concurrent users. The platform didn't blink. That's when we knew Storygame had built something solid. We've never had a failed transaction during a drop.”
