About
The problem it solves Indonesia faces a massive counterfeiting crisis, costing up to Rp 291 trillion (~$20B USD) annually. Consumers are routinely deceived into buying fake goods — from fashion and cosmetics to electronics and supplements — without any reliable way to verify authenticity. Tungky solves this by making authenticity verification simple, scalable, and secure using blockchain and NFT-based technology. ✅ **With Tungky, users can:** - UMKM & Brands: Mint a verifiable certificate for every product they sell, ensuring originality. - Buyers & Collectors: Instantly check product authenticity before purchasing. - Marketplaces & Logistic Partners: Integrate with Tungky to flag verified items and reduce counterfeit listings. By automating the issuance of digital proof and simplifying verification with QR/NFC or blockchain explorers, Tungky makes trust in commerce not just possible, but easy — especially for Indonesia's 30M+ micro-businesses.
How it's made
Challenges we ran into 🧩 **Challenges I Ran Into** 1. Abstracting Wallets for Non-Crypto Users Most UMKM and general users aren’t familiar with crypto wallets or gas fees. Asking them to manage private keys or MetaMask was a dealbreaker. → Solution: We implemented Account Abstraction (ERC-4337) so users interact with the platform like a regular app, while the wallet is managed invisibly behind the scenes. 2. Gas Fee Management at Scale Frequent minting on-chain can be costly and unpredictable, especially for small brands with high product volume. → Solution: We batch minting operations and subsidize gas fees using a relay network, supported by a token-based tier system. Brands get a quota through subscription, and only pay extra when limits are exceeded. 3. Integrating with Real-World Marketplaces We needed to design a way to integrate verification into Shopee, Tokopedia, and offline sales without their cooperation (initially). → Solution: We provide a lightweight Tungky Plugin/API for storefronts, plus generate public links and QR/NFC stickers that prove authenticity independently of any specific platform. this link for our presentation: https://www.canva.com/design/DAGu10xchj0/MeiqsgnB6RoaqulPi_nppA/edit?utm_content=DAGu10xchj0&utm_campaign=designshare&utm_medium=link2&utm_source=sharebutton
