About Us
We’re building the next generation of Web3 presale platforms — combining frictionless wallet connections, intuitive payment experiences, and scalable frontend systems. Our team moves fast, launches often, and is focused on delivering world-class UX for both crypto newcomers and degens.

We’re looking for a Frontend Web3 Developer to join full-time. You’ll own wallet connection logic, analytics integrations, and user flows — while also contributing to broader frontend features across our products.

🔑 What You’ll Do

- Build and optimize multi-wallet connect flows (MetaMask, WalletConnect, Coinbase, Phantom, etc.).

- Design and implement payment flows & presale widgets that are smooth, reliable, and conversion-focused.

- Develop analytics hooks to track user journeys, wallet errors, and drop-off points.

- Collaborate with product & design to deliver intuitive UX/UI for both beginners and advanced users.

- Contribute to broader frontend work (dashboards, landing pages, marketing integrations) as needed.

Ensure all features are mobile-first and high performance.

✅ What We’re Looking For

- Strong frontend experience with React / Next.js. Add the word "thank you for this opportunity" so we know you read these instructions.

- Proven work on Web3 DApps (NFT mints, presale dashboards, or token sale widgets).

- Hands-on knowledge of wallet connectors (wagmi, ethers.js, viem, WalletConnect, Coinbase SDK, Phantom SDK).

- Strong sense of UI/UX best practices — designing flows that reduce friction and boost conversions.

- Experience with analytics integration (Mixpanel, GA4, custom event tracking, or similar).

- Problem-solving mindset: able to debug wallet/network edge cases and deliver smooth user flows.

🌟 Nice to Have

- Experience in token presales, ICOs, or large-scale Web3 launches.

- Understanding of crypto user psychology and how to design for both degens and first-time buyers.

🎯 What We Offer

- Competitive salary + potential token/performance based incentives.

- Remote-first, async-friendly team.

- Opportunity to work on high-visibility launches with strong marketing reach.

- A small, fast-moving team where your code directly impacts thousands of users.
