NeuroSynapse is an innovative Android application that allows users to buy U.S. stocks securely using blockchain technology. The app integrates advanced features such as NFC ring authentication and real-time stock pricing to ensure a smooth and safe user experience.
-
Blockchain-Backed Stock Purchases: NeuroSynapse enables users to purchase U.S. stocks seamlessly using Ethereum blockchain technology.
-
Enhanced Security with NFC Ring: The app leverages the RingOFRingsSDK to boost security by requiring confirmation via an NFC ring before completing any stock purchase.
-
Real-Time Stock Prices: By integrating Chainlink technology, NeuroSynapse fetches real-time stock prices from the Ethereum blockchain, ensuring users have up-to-date information when making buying decisions.
-
NFT-Based Ownership: After purchasing a stock, users receive an ERC-721 NFT in their wallet. This NFT represents the value of the stock, offering a unique and verifiable ownership mechanism on the blockchain.
- Ethereum Blockchain: For decentralized and secure stock transactions.
- Chainlink: For fetching real-time stock price data from external sources.
- RingOFRingsSDK: For NFC ring-based authentication, ensuring enhanced security for stock purchases.
- ERC-721 NFTs: To represent purchased stock as digital assets in the user's wallet.
To retrieve stock prices for our application, we utilize the Polygon API. Polygon is a Web 2 API that allows access to real-time and historical stock data. We use this API to gather accurate and up-to-date market information.
To securely connect this data with our smart contracts, we leverage Chainlink Oracles. Chainlink provides a decentralized infrastructure that allows us to fetch data from Web 2 APIs and deliver it to blockchain-based smart contracts. By doing so, we can ensure the integrity and reliability of the data without relying on a single centralized source.

The RingOfRings holds the user’s wallet private key, making transactions easy and secure. When the user wants to buy a stock, they log in to MetaMask, then use the ring to check the private key stored on it. The ring signs a message, and from that, the public key is extracted and compared with the public key from MetaMask. If they match, the transaction goes through; if not, it’s rejected. This adds an extra layer of security to make sure everything is legit.
