We are looking for someone to make a simple cryptocurrency wallet application. We will supply an easy to use SDK that allows you to build and sign transactions and obtain wallet info (public key, address) using a private key. Making transactions and receiving blockchain information (balances, blocks, transactions etc.) will be done with simple http calls to an api endpoint (for example using fetch). Screens for most features will be supplied. All elements in the screen must be made as reusable typescript React components. Features: 1. Login with encrypted private key + passphrase 2. Create new wallet (generate private key + let user encrypt with passphrase) 3. Store encrypted private key in json file so user can login with only passphrase in future 4. After login, show wallet info (address, balances, transaction history), and buttons that open modals with forms for making transactions. Other info: - Wallet info is retrieved with simple GET calls to a http endpoint, only need to send wallet address. - Sending transactions is done with simple POST calls to a http endpoints, only need to send signed transaction (generated with our sdk). - Transactions are constructed and signed using our simple SDK (looks like: "Transaction(type, amount, from, to).sign(privateKey)"). - When making a transaction, user must re-enter their encrypted key's passphrase, which then decrypts the encrypted private key which is stored in the state. Requirements: - Must be written in Typescript - React front-end with reusable components - React Redux for state management - Runs on Electron Please supply any past experience with this type of stack. Experience with cryptocurrency wallet development is a plus.
