> Deploy smart contracts to local network or Mega testnet

# mega deploy

The `deploy` command (also aliased as `mega create`) deploys smart contracts to either a local development network or the Mega testnet.

## Usage

```bash theme={null}
mega deploy <contract> [options]
```

## Arguments

| Argument   | Description                                                                         |
| ---------- | ----------------------------------------------------------------------------------- |
| `contract` | Path to the contract file and contract name (e.g., `src/MyContract.sol:MyContract`) |

## Options

| Option                         | Description                                              |
| ------------------------------ | -------------------------------------------------------- |
| `--testnet`                    | Deploy to Mega testnet instead of local network          |
| `--broadcast`                  | Broadcast the transaction instead of doing a dry run     |
| `--constructor-args [args...]` | The constructor arguments                                |
| `--verify`                     | Verify contract after creation                           |

  This command supports all options available in `forge create`. See the
  [Forge documentation](https://book.getfoundry.sh/reference/forge/forge-create) for a complete list.

## Description

This command deploys Solidity smart contracts to a blockchain network. By default, it deploys to a local Anvil network, but you can use the `--testnet` flag to deploy to the Mega testnet.

The command is a wrapper around Foundry's `forge create` with additional features specific to the Mega ecosystem.

## Examples

### Deploy to local network (dry run)

```bash theme={null}
mega deploy src/MyContract.sol:MyContract
```

### Deploy to local network and broadcast the transaction

```bash theme={null}
mega deploy src/MyContract.sol:MyContract --broadcast
```

### Deploy to Mega testnet using a stored account

```bash theme={null}
mega deploy src/MyContract.sol:MyContract --testnet --broadcast --account <account-name>
```

### Deploy to Mega testnet using a private key

```bash theme={null}
mega deploy src/MyContract.sol:MyContract --testnet --broadcast --private-key <private-key>
```

### Deploy with constructor arguments

```bash theme={null}
mega deploy src/MyContract.sol:MyContract --broadcast --constructor-args "Hello World" 123
```
