TLaaS (LEX) — Deployment Scripts (Testnet & Mainnet): Environment Management

1. Purpose

Deployment scripts in TLaaS (LEX) automate the rollout of smart contracts to both testnet and mainnet environments. Proper deployment management ensures smooth integration with TLAAS (DLA) for validation and DAL for governance, while maintaining version control and auditability.

2. Deployment Goals

• Ensure consistent contract deployment across environments.
• Minimize configuration errors through automation.
• Maintain deployment logs for transparency and compliance.
• Support staged rollouts with verification steps.

3. Environment Setup

• Testnet: Used for QA, validator testing, and integration with TLAAS/DAL staging modules.
• Mainnet: Production environment for live licenses and marketplace activity.
• Config Files: Store network RPC URLs, private keys, and contract parameters in

4. Hardhat Deployment Script Example

const { ethers } = require("hardhat");

async function main() {
  const [deployer] = await ethers.getSigners();
  console.log("Deploying contracts with account:", deployer.address);

  const LicenseRegistry = await ethers.getContractFactory("LicenseRegistry");
  const registry = await LicenseRegistry.deploy();
  await registry.deployed();

  console.log("LicenseRegistry deployed to:", registry.address);
}

main()
  .then(() => process.exit(0))
  .catch((error) => {
    console.error(error);
    process.exit(1);
  });

5. Deployment Best Practices

• Dry Runs: Deploy to a local Hardhat network before testnet.
• Verify Contracts: Use
• Version Control: Tag deployments with Git commits.
• Backup Keys: Store deployment keys in secure vaults.
• Gas Management: Set appropriate gas limits and prices per network.

6. Post-Deployment Tasks

• Assign roles (issuer, validator) via governance or admin scripts.
• Configure royalty routing parameters.
• Register contract addresses in the DApp front end.
• Publish deployment details to governance forums for transparency.

7. Interoperability

• TLaaS (LEX): Direct deployment of marketplace contracts.
• TLAAS (DLA): Integration with validator verification contracts.
• DAL: Link to governance and dispute modules post-deployment.

8. Benefits

• Reduces human error in deployments.
• Ensures reproducibility across environments.
• Supports faster rollouts with minimal downtime.
• Maintains a complete history of deployment actions.
