Hello 👋

We at Dynamic are super passionate and excited about wallets and their promise (see our blog).

One example is supporting the creation of non-custodial wallets for users who don’t have wallets yet and are starting their journey on Web3 (see our blog).

In this exercise, you are going to build the Venmo of wallets. 💰  We call it “VenCura”

<aside> 🤯 Thank you GPT ❤️ “The name combines the words "Venmo" and "Custodian" to create a unique name that suggests a safe and reliable financial service. "Cura" means "care" or "guardianship" in Latin, which fits with the idea of a custodian service.”

In this take-home, you will build an API platform (with a basic UI) to generate custodial wallets on the backend with support for basic actions. We leave it kinda open-ended to not limit your creativity and to let you focus on things that you are interested in, within this problem.

Requirements:

• Use Dynamic for the authentication layer.
• An authenticated user can create at least one account/wallet.
• All the interactions with the custodial wallet would be done on the backend via an API.
• A user can perform at least these actions on the wallet:
  • getBalance() → balance: number (get the current balance on the wallet.
  • signMessage(msg: string) → signedMessage: string (The signed message with the private key)
  • sendTransaction(to: string, amount: number) → transactionHash: string (sends a transaction on the blockchain)
• Basic UI to interact with the API.
• We use TypeScript, Node and React, but our core product needs to work seamlessly with many different build tools and frameworks.

What to focus on:

• Code + API + Schema design and implementation.
