# Deployments

Deploying decentralized identity (dID) on a new rollup blockchain requires several steps to ensure seamless integration and compatibility with the DiD Layer. Below is a structured guide on how to deploy dID on a new rollup blockchain.

### Step 1: Integrate DiD Layer Contracts

The first step is to integrate the DiD Protocol contracts into the rollup blockchain. These contracts handle identity management, mapping user-friendly names to wallet addresses, and facilitating decentralized application (dApp) interactions.

***

### Step 2: Understand Smart Contracts

Familiarize yourself with the DiD Layer [Smart Contracts](/snowball/decentralized-identity-layer/technical-documentation/smart-contracts.md), including:

Understanding these contracts ensures proper implementation within the rollup blockchain.

***

### Step 3: Prepare the Development Environment

Set up a development environment with the necessary tools:

* **EVM-Compatible Rollups**: Install Truffle or Hardhat.
* **Other Environments**: Await future updates for compatibility.
* **Version Control**: Use Git for managing changes.

***

### Step 4: Review the Contract Code

Examine the smart contract source code for:

* Structure and function logic.
* Configurable parameters.
* Alignment with project requirements.

***

### Step 5: Customize Configuration

Modify the smart contracts as needed:

* Adjust contract parameters.
* Configure network settings.
* Integrate with existing systems.

**Important**: Any modifications should be reviewed and audited to maintain compatibility with DiD Layer Protocol.

***

### Step 6: Compile Contracts

Compile the smart contracts into bytecode and ABI artifacts using Truffle or Hardhat. This ensures readiness for blockchain deployment.

***

### Step 7: Configure Deployment Settings

Define deployment parameters:

* **Gas limits** and **transaction fees**.
* **Network endpoints**.
* **Initial contract values**.

***

### Step 8: Implement Rollup Messaging Protocol

* **Default Protocol**: DiD Layer supports LayerZero out of the box.
* **Additional Protocols**: Can be requested based on rollup requirements.
* **Synchronization**: Integrate DiD Layer with the rollup’s messaging protocol to ensure smooth data exchange.

***

### Step 9: Ensure Security and Auditing

Conduct security audits and testing:

* **Code Reviews**: Ensure best practices are followed.
* **Penetration Testing**: Identify vulnerabilities.
* **Deployment Simulation**: Use testnets for validation.

***

### Step 10: Develop User Interface

Build a UI for managing dID on the rollup blockchain:

* **User-friendly design**.
* **Features for creating, updating, and interacting with identities**.
* **Integration with real-time data from DiD Layer**.

***

### Step 11: Deploy on Testnet

Before mainnet deployment:

* Deploy dID on a testnet.
* Conduct thorough validation.
* Address any issues found.

***

### Step 12: Deploy on Mainnet

After successful testnet validation:

* Deploy the solution on the mainnet.
* Provide documentation.
* Inform users and developers about the new dID integration.

***

### Step 13: Monitor and Maintain

* Continuously track performance and user adoption.
* Address emerging issues.
* Update the dID solution as rollup technologies evolve.
