We need to create a website where users can come, sign up and create a cloud wallet for themselves. They can login via username and password, create new wallets, ask the backend to sign a transaction on their behalf.

• User signs up
• User signs in
• Users asks to sign a txn
• User asks for the status of a problem

Hints

• Node polyfills in react
• String private key to uint8array
• Serializing transactions in solana
