   The below instructions for verifying on our Sepolia Blockscout instance will need to be altered to work with Etherscan
   deployments. As additional services come online for mainnet, we'll update these instructions.

 ## Using Developer Tools
 
-Most smart contract tooling has plugins for verifying your contracts easily on Etherscan. Blockscout supports Etherscan's contract verification APIs, and it's straightforward to use these tools with the Scroll Sepolia Testnet.

 ### Foundry
 
-<Aside type="danger" title="Warning">
+When using Foundry, the `verify-contract` command helps automate the process of verifying contracts. If your contract has constructor arguments, you can specify these in ABI-encoded form with the `--constructor-args` option. For example, if your constructor takes two `uint256` variables:
+```bash
+ --constructor-args $(cast abi-encode "constructor(uint256,uint256)" 0 7)
+```
+
+Refer to the [Foundry documentation](https://book.getfoundry.sh/reference/forge/forge-verify-contract) for further options you can specify.
+
+
+#### Scrollscan
+
+You will need to [register an account](https://scrollscan.com/register) to create an API key. The same key can be used for both Scroll Sepolia and mainnet. After creating your API key, please wait a few minutes before it comes into effect.
+
+```bash
+forge verify-contract <contract address> <contract name> \
+  --verifier-url https://api-sepolia.scrollscan.com/api \
+  --etherscan-api-key <your Scrollscan API key> \
+  --constructor-args <your constructor arguments>
+```
+<Aside type="caution" title="Caution">
+  Do not specify the chain ID.

+
+#### Blockscout
+
+{/* <Aside type="danger" title="Warning">
   Our Blockscout instance currently has inconsistent behavior in verifying contracts with Foundry. We're working on a
   fix, along with other stability improvements. Don't hesitate to come ask for help [on
   Discord](https://discord.com/channels/853955156100907018/1028102371894624337) though.
