Client's Testimonial

"The speed and expertise of the Developers.dev team were unbelievable. They took our GDD and delivered a polished, playable Web3 game MVP in just three months. Their Blockchain/Web3 Pod understood the nuances of smart contracts, wallet integration, and creating a gas-efficient user experience. We successfully closed our Series A funding thanks in large part to the high-quality demo they built."

Client Overview

A venture-backed startup in Austin, Texas, aiming to disrupt the collectible card game (CCG) market with a play-to-earn model. The game's core innovation was true ownership of digital assets, with each card being a unique NFT on the Polygon blockchain. The founders had a strong vision and a game design document but needed a technical partner to build a functional MVP to secure their next round of funding.

Problem

The startup needed to quickly build a compelling MVP that demonstrated not only fun gameplay but also the seamless integration of blockchain technology. They had to prove to investors that their concept was technically feasible and that they could create a user-friendly experience for both crypto-native and traditional gamers.

Key Challenges

Aggressive Timeline

A functional MVP was needed within 12 weeks to align with their fundraising schedule.

Complex Technology Stack

The project required expertise in Unity for the game client, Solidity for smart contracts, and web technologies for a marketplace.

User Experience (UX)

The process of connecting a crypto wallet, minting NFTs, and transacting on the blockchain had to be simple and intuitive to avoid alienating mainstream players.

Security

The smart contracts handling valuable NFT assets had to be audited and secure against exploits.

Our Solution

Developers.dev assembled a dedicated POD, including a business analyst, UI/UX designer, two full-stack developers, and a QA automation engineer. We proposed a custom, cloud-based Legal Practice Management (LPM) platform.We deployed our "Blockchain / Web3 Pod," a cross-functional team tailored for the project's unique needs.

🎮 Game Client (Unity)

Our Unity developers focused on building the core CCG mechanics: deck building, card battles, and visual effects.

⛓️ Smart Contracts (Solidity)

Our blockchain specialists wrote, tested, and deployed the ERC-1155 smart contracts on the Polygon testnet for minting and trading the NFT cards.

💳 Wallet Integration

We used SDKs like WalletConnect and MetaMask to create a smooth, secure process for players to connect their crypto wallets to the game.

🌐 Web Marketplace

A small team of full-stack developers built a basic web-based marketplace where players could view and trade their NFT cards outside of the game client.

Implementation and Execution

Design Sprint

The project kicked off with a one-week design sprint to finalize the user flow for the entire experience, from onboarding to gameplay to trading.

Two-Week Sprints

The team worked in six, two-week sprints, focusing on delivering playable builds at the end of each sprint.

Testnet Deployment

All blockchain interactions were first deployed and tested rigorously on the Polygon Mumbai testnet to ensure functionality without risking real funds.

Third-Party Audit

We facilitated a security audit of the smart contracts with a reputable third-party firm before the MVP presentation.

Investor Demo Build

The final sprint was dedicated to polishing a specific build for the investor demo, ensuring a bug-free and impressive presentation.

Full Documentation

We provided comprehensive technical documentation for the entire system, a key asset for the client's due diligence process.

Positive Outcome

💰 Successful Fundraising

The startup successfully used the MVP to close a $10 million Series A funding round.

⏱️ MVP Delivered on Time

The fully functional MVP was delivered in the 12-week timeframe, meeting the critical fundraising deadline.

👍 Positive User Feedback
