Oyano

Oyano is a security-focused Web3 wallet built to protect users from interacting with fraudulent smart contracts during NFT mints or token purchases. The app leverages Privy’s Server Wallets for seamless transaction management, allowing users to avoid creating private keys and wallets manually. Privy’s Policy Engine enforces strict rules to ensure only verified transactions are processed. The app maintains an on-chain allowlist and denylist of smart contracts to help users interact only with safe, vetted projects.

Key Features:

Contract Allowlist/Denylist: Prevents interactions with flagged smart contracts while allowing verified ones. Scam Detection System: Automatically blocks risky transactions using Privy’s Policy Engine and a real-time scam detection API. Mint Insurance: Offers refund protection for users if a contract is later identified as fraudulent. Community Reviews: Users can leave and read feedback about smart contracts, helping others avoid scams. Notifications: Real-time alerts for users when interacting with potentially dangerous contracts.

Technologies Used:

Next.js: Frontend framework for building the app interface and APIs. Privy Server Wallets: Handles wallet creation, signing, and transaction management on the Ethereum network. Privy Policy Engine: Enforces transaction rules, ensuring only safe transactions are processed.
