The ModuleKit has a helper to easily deploy modules and register them on the Module Registry. This will allow easy discoverability and useage of your module.

​
Create the .env file

Create a .env file in the root directory based on the .env.example (if you are using the module template) file and fill in the variables: 
PK=
DEPLOYMENT_SENDER=
DEPLOYMENT_RPC=
ETHERSCAN_API_KEY=

​
Create the deployment script

To use the RegistryDeployer, you need to create a new Foundry script and import the following objects: 
import "forge-std/Script.sol";
import { RegistryDeployer } from "modulekit/deployment/RegistryDeployer.sol";

​
Write the deployment script

Then, create a new contract, like the following example: 
/// @title DeployModuleScript
contract DeployModuleScript is Script, RegistryDeployer {
    function run() public {
        // Setup module initCode, metadata and resolverContext
        bytes memory initCode = type(MODULE_CONTRACT).creationCode;
        bytes memory metadata = "";
        bytes memory resolverContext = "";

        // Get private key for deployment
        vm.startBroadcast(vm.envUint("PK"));

        // Deploy module
        address moduleAddr = deployModule({
            initCode: initCode,
            salt: bytes32(0),
            metadata: metadata,
            resolverContext: resolverContext
        });

        // Stop broadcast and log module address
        vm.stopBroadcast();
        console.log("Deploying module at: %s", moduleAddr);
    }
}
Replace MODULE_CONTRACT with the contract you want to deploy. In most cases, metadata and resolverContext can be left empty.

​
Run the deployment script

To run the deployment script, you can use the following command: 
source .env && forge script script/DeployModule.s.sol:DeployModuleScript --rpc-url $DEPLOYMENT_RPC --broadcast --sender $DEPLOYMENT_SENDER --verify
Note: you might need to adjust the script path and name to match your setup. Your module is now deployed to the blockchain and verified on Etherscan.

​
Manually verify the module (optional)

If the verification on the block explorer fails, you can manually verify it on Etherscan using the following command (replace the placeholders with your actual values): 
source .env && forge verify-contract --chain-id [YOUR_CHAIN_ID] --watch --etherscan-api-key $ETHERSCAN_API_KEY [YOUR_MODULE_ADDRESS] src/[PATH_TO_MODULE].sol:[MODULE_CONTRACT_NAME]
