To verify a smart contract on the Rootstock CLI, the `rsk-cli` verify command allows developers to submit their contract source code and other information to the Rootstock Explorer API.

The `rsk-cli` verify command enables the verification of a smart contract on Rootstock's mainnet or testnet by providing the contract code, address, and other metadata through a JSON file.

Verification on Rootstock's blockchain allows users to confirm that the compiled bytecode on the blockchain matches the source code.

**Mainnet:**

```
  rsk-cli verify --json <path_to_json> --address <address> --name <contract_name> --decodedArgs <arg1> <arg2> ...

**Testnet:**

```
rsk-cli verify --testnet --json <path_to_json> --address <address> --name <contract_name> --decodedArgs <arg1> <arg2> ...

To verify the same contract on the testnet:

```bash
rsk-cli verify --testnet --json artifacts/build-info/fb7b3667b850d874bffe750e005d2477.json --address 0x4edd891c2e988e6145fe3e418c652ee33ebab9ae --name ContactInfo
```

With constructor arguments:

```bash
rsk-cli verify --testnet --json ./contract.json --address 0x1234567890abcdef1234567890abcdef12345678 --name MyToken --decodedArgs 0xabcdef1234567890abcdef1234567890abcdef12 1000
```

The response below was obtained from the command without a constructor.
