PetLog is a Web3-based decentralized biodata system for pets, built to store and verify lineage, vaccination, and health records on-chain.
"Every pet deserves a verified story."
PetLog is a Web3-based decentralized biodata system for pets, built to store and verify lineage, vaccination, and health records on-chain.
By connecting breeders, veterinarians, and owners through validator-based smart contracts, PetLog eliminates fake certificates and fragmented data — creating trust, transparency, and traceability across the global pet ecosystem.
PetLog revolutionizes pet ownership verification by creating immutable, blockchain-based digital identities for pets. Built on Cardano Pre-Production testnet, each pet receives a unique NFT passport containing verified lineage, health records, and ownership history.
Hackathon Project: Building trust in pet ownership through decentralized digital passports on Cardano
42% of pedigree certificates in Asia are unverifiable (Asian Kennel Network, 2024)
73% of veterinary clinics in Indonesia use manual records (Indonesian Veterinary Association, 2023)
No standardized system for pet data verification across developing markets
PetLog creates a blockchain-based trust network where:
🧬 Immutable Lineage Records from certified breeders
💉 Verified Health Logs digitally signed by veterinarians
🪪 NFT Pet Passports that travel with ownership transfers
🔗 Validator Network of trusted pedigree associations and clinics
🔐 Wallet Integration: Seamless connection with Cardano wallets (Nami, Eternl, Gero, Flint)
🎨 Guided Minting Flow: Intuitive pet passport creation with IPFS asset storage
📱 Personal Gallery: View all owned pet passports with metadata resolution via Blockfrost
🔍 Passport Details: Complete pet profiles with explorer links and provenance tracking
⚡ CIP-25 Compliant: Following Cardano NFT metadata standards
🌐 IPFS Integration: Decentralized storage via Pinata for pet photos and documents
