### Sign EVM transactions with mnemonic and optional bip44 path

#### Example

```
const mnemonic = 'all all all all all all all all all all all all'

const transaction = {
    to: `0x8a65ac0e23f31979db06ec62af62b132a6df4741`,
    data: `0x12345c0e23f31979db06ec62af62b132a6df4741`,
    gasLimit: 200000,
    gasPrice: `0x123`,
    value: '0x456',
    chainId: 1,
}

const message = 'Message to sign'
```

```
