## Wallet operations

Cast provides wallet utilities for key generation, signing, and verification.

### Creating wallets

:::code-group
```bash [Random]
$ cast wallet new
```

```bash [Multiple]
$ cast wallet new --number 5
```

```bash [From mnemonic]
$ cast wallet derive "abandon abandon ... about"
```

```bash [Specific mnemonic index]
$ cast wallet private-key "abandon abandon ... about" 2
```
:::

### Keystore management

:::steps
#### Create a keystore

```bash
$ cast wallet import my-key --interactive
```

Enter your private key when prompted, then set a password.

#### List keystores

```bash
$ cast wallet list
```

#### Get address from keystore

```bash
$ cast wallet address --keystore ~/.foundry/keystores/my-key
```
:::

### Signing messages

:::code-group
```bash [With private key]
$ cast wallet sign "Hello, Ethereum!" --private-key $KEY
```

```bash [With keystore]
$ cast wallet sign "Hello, Ethereum!" --keystore ~/.foundry/keystores/my-key
```

```bash [With browser wallet]
$ cast wallet sign "Hello, Ethereum!" --browser
```

```bash [Sign a 32-byte hash]
$ cast wallet sign --no-hash $HASH --private-key $KEY
```
:::

### EIP-712 typed data

Sign structured data according to EIP-712:

```bash
$ cast wallet sign --data '{
    "types": {
      "EIP712Domain": [
        {"name": "name", "type": "string"},
        {"name": "version", "type": "string"},
        {"name": "chainId", "type": "uint256"}
      ],
      "Mail": [
        {"name": "from", "type": "address"},
        {"name": "to", "type": "address"},
        {"name": "contents", "type": "string"}
      ]
    },
    "primaryType": "Mail",
    "domain": {
      "name": "Ether Mail",
      "version": "1",
      "chainId": 1
    },
    "message": {
      "from": "0xCD2a3d9F938E13CD947Ec05AbC7FE734Df8DD826",
      "to": "0xbBbBBBBbbBBBbbbBbbBbbbbBBbBbbbbBbBbbBBbB",
      "contents": "Hello, Bob!"
    }
  }' --private-key $KEY
```

Use `--browser` instead of a private-key option to sign the typed data with an injected browser wallet. Browser wallets support personal-message and EIP-712 signing, but not raw-hash signing with `--no-hash`.

### Verifying signatures

```bash
$ cast wallet verify --address $SIGNER "Hello, Ethereum!" $SIGNATURE
```

### EIP-7702 account delegation

Use `cast wallet sign-auth` to create a signed authorization that delegates an EOA's execution to a contract implementation. The authorization can be submitted by the authority or a separate broadcaster.

See [EIP-7702 account delegation](/cast/eip-7702-delegation) for signing, nonce selection, broadcasting, verification, and clearing instructions.

### Vanity addresses

Generate addresses matching a pattern:

:::code-group
```bash [Starts with]
$ cast wallet vanity --starts-with dead
```

```bash [Ends with]
$ cast wallet vanity --ends-with beef
```

```bash [Prefix and suffix]
$ cast wallet vanity --starts-with 00 --ends-with 00
```
:::

### Address utilities

:::code-group
```bash [Checksum]
$ cast to-check-sum-address 0xd8da6bf26964af9d7eed9e03e53415d37aa96045
```

```bash [CREATE address]
$ cast compute-address $DEPLOYER --nonce 5
```

```bash [CREATE2 address]
$ cast create2 --starts-with 00 --init-code $BYTECODE --deployer $FACTORY
```
:::

### Hardware wallets

:::code-group
```bash [List Ledger]
$ cast wallet list --ledger
```

```bash [List Trezor]
$ cast wallet list --trezor
```

```bash [Sign with Ledger]
$ cast wallet sign "Hello" --ledger
```
