Deploys a contract to the network, given bytecode & constructor arguments.

## Usage

:::code-group
```ts [example.ts]
import { wagmiAbi } from './abi'
import { account, walletClient } from './config'

const hash = await walletClient.deployContract({
  abi,
  account,
  bytecode: '0x608060405260405161083e38038061083e833981016040819052610...',
})
```

```ts [abi.ts]
export const wagmiAbi = [
  ...
  {
    inputs: [],
    stateMutability: "nonpayable",
    type: "constructor",
  },
  ...
] as const;
```

```ts [client.ts]
import { createWalletClient, custom } from 'viem'
import { privateKeyToAccount } from 'viem/accounts'
import { mainnet } from 'viem/chains'

export const walletClient = createWalletClient({
  chain: mainnet,
  transport: custom(window.ethereum)
})

// JSON-RPC Account
export const [account] = await walletClient.getAddresses()
// Local Account
export const account = privateKeyToAccount(...)
```

})
```

### args (if required)

* **Type:** Inferred from ABI.

Constructor arguments to call upon deployment.
