## Introduction
Create and interact with Crossmint wallets in EVM. This quickstart uses Crossmint Auth and uses your external wallet (e.g Phantom, Metamask, Coinbase, etc.) as a signer for that wallet.
**Learn how to:**
- Create a wallet
- View its balance for ETH and ERC20 tokens
- Send a transaction
- Add delegated signers to allow third parties to sign transactions on behalf of your wallet
## Deploy
Easily deploy the template to Vercel with the button below. You will need to set the required environment variables in the Vercel dashboard.
[](https://vercel.com/new/clone?repository-url=https%3A%2F%2Fgithub.com%2FCrossmint%2Fevm-wallets-quickstart&env=NEXT_PUBLIC_CROSSMINT_API_KEY&env=NEXT_PUBLIC_CHAIN)
## Setup
1. Clone the repository and navigate to the project folder:
```bash
git clone https://github.com/crossmint/evm-wallets-quickstart.git && cd evm-wallets-quickstart
```
2. Install all dependencies:
```bash
npm install
# or
yarn install
# or
pnpm install
# or
bun install
```
3. Set up the environment variables:
```bash
cp .env.template .env
```
4. Get a Crossmint client API key from [here](https://docs.crossmint.com/introduction/platform/api-keys/client-side) and add it to the `.env` file. Make sure your API key has the following scopes: `users.create`, `users.read`, `wallets.read`, `wallets.create`, `wallets:transactions.create`, `wallets:transactions.sign`, `wallets:balance.read`, `wallets.fund`.
```bash
NEXT_PUBLIC_CROSSMINT_API_KEY=your_api_key
```
5. Set the chain you want to use. (default is `optimism-sepolia`)
```bash
NEXT_PUBLIC_CHAIN=your_chain
```
5. Run the development server:
```bash
npm run dev
# or
yarn dev
# or
pnpm dev
# or
bun dev
```
## Using in production
1. Create a [production API key](https://docs.crossmint.com/introduction/platform/api-keys/client-side).
