The problem Tungky 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.

Challenges I 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.
