# Verify using Foundry

## Verify your Contract

To verify your smart contract that is already deployed, refer the instructions in [Blockscout's Foundry Contract Verification](https://docs.blockscout.com/devs/verification/foundry-verification) page. 

Run the following command to verify on **Plume Testnet** for instance (switch the RPC and verifier URL to Mainnet to deploy on Plume Mainnet):

```sh
export PLUME_RPC_URL=https://testnet-rpc.plume.org
export VERIFIER_URL=https://testnet-explorer.plume.org/api/
export CONTRACT_ADDRESS=<your_contract_address>
export CONTRACT_PATH=<contract_file>:<contract_name>

forge verify-contract $CONTRACT_ADDRESS $CONTRACT_PATH \
    --rpc-url $PLUME_RPC_URL \
    --verifier blockscout \
    --verifier-url $VERIFIER_URL
```

{% hint style="warning" %}
Make sure to replace the details in the `<contract address>` and `<contract_file>:<contract_name>` with your contract details.
{% endhint %}
