About

## 👕 OnChainDrips - NFC-Enabled Merchandise for the Web3 Era I don’t like the word **“free.”** Because when merch is free, it usually has **no value**. It becomes *just another T-shirt*, worn once, forgotten later, and eventually buried somewhere in a closet. And that’s sad, because merch **should mean something**. OnChainDrips started with a simple belief: 👉 **Merch should carry value, identity, and information and not just a logo.** --- ### 🧵 What is OnChainDrips? OnChainDrips is a **B2B merchandise partner for Web3 companies**, helping protocols, exchanges, and ecosystems create high-quality merch for conferences, hackathons, and community events around the world. But we didn’t stop at printing T-shirts. We asked: **What if merch actually mattered?** What if it could be **owned**, **verified**, **traded**, and even used for **networking**? That’s where **NFC-enabled T-shirts** come in. --- ### 📲 From T-shirt → Tap → On-chain Asset Each OnChainDrips T-shirt comes with an **embedded NFC tag** and is linked to a **unique on-chain asset** under a specific event drop for example: *Bybit Token2049 Dubai – Exclusive Drop*. Here’s how it feels for an attendee 👇 1️⃣ You grab a T-shirt at the event 2️⃣ You tap your phone on it 📱 3️⃣ You log in using Google (no wallets, no seed phrases) 4️⃣ You mint the NFT — **gasless**, sponsored by us 5️⃣ Boom 💥 the T-shirt is now **yours**, both physically and on-chain No friction. No crypto anxiety. Just a clean Web2-like experience. --- ### 🧾 What does the NFT represent? Each NFT acts as: * 🎟 **Proof of Attendance** * ✅ **Proof of Authenticity** * 🖼 **A digital collectible tied to a real physical item** Scarcity is enforced by design. If a drop has **100 T-shirts**, only **100 on-chain assets** can ever exist. Period. You can **reserve or bid** for exclusive pieces during events, mint them to your wallet, and manage your entire collection directly from the OnChainDrips platform. --- ### 🤝 Merch as a Networking Primitive Here’s where it gets really interesting. Your T-shirt isn’t just merch — it’s **identity**. Owners can optionally attach: * Name * Role * Social links * Portfolio or ENS details Now imagine this at an event 👀 You meet someone, tap their T-shirt… …and instantly get their verified profile. No awkward phone exchanges. No “bro what’s your Twitter?” Just **tap → connect → move on**. Networking, but effortless. ---

How it's made

## ⚙️ Technology Stack & How It All Fits Together We built OnChainDrips with a **modular, Web3-first architecture**, but with a strong focus on **real-world usability**. --- ### ⛓️ Sui Blockchain Sui is our core blockchain layer. Each T-shirt maps to a **unique on-chain object**, giving us: * 1:1 mapping between physical merch and digital ownership * Verifiable ownership & transfers * Guaranteed scarcity per event drop We use **zkLogin on Sui**, so users can sign in using **Google** — no seed phrases, no prior crypto knowledge, but still a real self-custodial wallet under the hood. --- ### 🗂️ Walrus (Decentralized Storage) Walrus is used to store: * NFT images * T-shirt artwork * Drop metadata (event, brand, rarity) * Future unlockable experiences Only lightweight references live on-chain. Heavy data stays decentralized, verifiable, and retrievable via Walrus. --- ### 🪪 ENS (Identity Layer) If a user owns an ENS name, we fetch and attach: * Display name * Social links * Public identity details This turns every T-shirt into a **portable identity badge**. --- ### 💛 Yellow (Bidding & Reservations) For reserving and bidding on limited drops, we use **Yellow** with test USDC on Sepolia. This enables: * Seamless bidding and reservations * Web2-style UX * No wallet popups * No message signing Basically: *crypto rails, but zero crypto friction.* --- ### ⚡ Sponsored Transactions All minting transactions are **sponsored by OnChainDrips**: * No gas fees for users * Instant minting at events * First-time users don’t need tokens Perfect for noisy, fast-paced conference environments. --- ### 🧩 Additional Tech * **Next.js + TypeScript** for the frontend * **Supabase backend and offchain storage** for orchestration, validation, and gas sponsorship * **NFC hardware integration** to bridge physical and digital worlds * **Decentralized identity principles** so users always own their assets and data --- ## 🌍 The Outcome By combining **physical merchandise, NFC interaction, on-chain ownership, and decentralized storage**, OnChainDrips turns event merch into: * 🎁 Collectibles with real value * 🧾 Proof of participation * 🪪 Identity & networking tools * 🧠 Cultural artifacts of Web3 history OnChainDrips doesn’t make “free merch”. We make merch you actually **care about**. Merch you **wear**, **own**, **trade**, and **remember**. 🚀
