Verify With Hardhat

#1. Configure RBAScan

Add the RBAScan Testnet configuration to your hardhat.config.js or hardhat.config.ts.

etherscan: {
  apiKey: {
    "roburna-testnet": "empty",
  },

  customChains: [
    {
      network: "roburna-testnet",
      chainId: 159,

      urls: {
        apiURL: "https://testapi.rbascan.com:443/api/",
        browserURL: "https://testnet.rbascan.com",
      },
    },
  ],
},

RBAScan does not require a traditional API key for this configuration, so "empty" is used as the value.

#2. Verify the Contract

Run: npx hardhat verify
--network roburna-testnet
YOUR_CONTRACT_ADDRESS

Replace YOUR_CONTRACT_ADDRESS with the address of your deployed contract.

#3. Constructor Arguments

If your contract has constructor arguments, provide them after the contract address. For example: npx hardhat verify
--network roburna-testnet
YOUR_CONTRACT_ADDRESS
"Constructor Argument"

For multiple constructor arguments, provide each argument in the same order used during deployment.

#4. Check the Result

After successful verification, open the contract on RBAScan Testnet. The contract source code should now be available under the Contract section.
