# Parameters

The erc20 module contains the following parameters:

| Key             | Type | Default Value |
| --------------- | ---- | ------------- |
| `EnableErc20`   | bool | `true`        |
| `EnableEVMHook` | bool | `true`        |

### Enable ERC20 <a href="#enable-erc20" id="enable-erc20"></a>

The `EnableErc20` parameter toggles all state transitions in the module. When the parameter is disabled, it will prevent all token pair registration and conversion functionality.

### Enable EVM Hook <a href="#enable-evm-hook" id="enable-evm-hook"></a>

The `EnableEVMHook` parameter enables the EVM hook to convert an ERC20 token to a Cosmos Coin by transferring the Tokens through a `MsgEthereumTx` to the `ModuleAddress` Ethereum address.
