Working with LSPs on Remix IDE

This guide will walk you through the process of building and deploying LSP smart contracts using Remix IDE.

Setting Up Dependencies

First, create a package.json file with the required LSP smart contract dependencies to the root of your project:

{
  "dependencies": {
    "@erc725/smart-contracts-v8": "npm:@erc725/[email protected]",
    "@erc725/smart-contracts": "^7.0.0",
    "@openzeppelin/contracts": "^4.9.3",
    "@lukso/lsp1-contracts": "~0.15.0",
    "@lukso/lsp2-contracts": "~0.15.0",
    "@lukso/lsp14-contracts": "~0.15.0",
    "@lukso/lsp17contractextension-contracts": "~0.15.0",
    "@lukso/lsp20-contracts": "~0.15.0"
  }
}

Deploying using the Universal Profile browser extension

To deploy your smart contract using the Universal Profile browser extension:

• Click on the Customize this list option in the Environment field
• Activate the option of Injected Provider - Universal Profile under the Deploy using a Browser Extension.

Verifying the Contract

To verify your contract on the LUKSO Testnet:

1. Enable Contract Verification

   • Open the Plugin Manager in Remix
   • Activate the Contract Verification tool
   • The verification icon will appear in the left menu

2. Configure Blockscout API

   • Navigate to the Settings tab
   • Add the LUKSO Testnet Blockscout API:

     https://explorer.execution.testnet.lukso.network/api

3. Verify Contract

   • Go to the Verify tab
   • Fill in the following details:
     • Chain: LUKSO Testnet (4201)
     • Contract Address: Your deployed contract address
     • Contract Name: Select your contract's Solidity file
   • Enter the same constructor parameters used during deployment
   • Ensure Blockscout is selected
   • Click the "Verify" button

After verification, your contract will be visible and verified on the LUKSO Testnet explorer.
