 ## Verifying Your Contract
 
-If you want to verify your contract on Etherscan:
+Ink uses [Blockscout](https://explorer-sepolia.inkonchain.com) as its block explorer — not Etherscan.
+To verify your contract after deployment, use the `--verifier blockscout` flag:
 
 ```bash
 forge verify-contract <DEPLOYED_CONTRACT_ADDRESS> src/InkContract.sol:InkContract \
     --chain-id 763373 \
-    --etherscan-api-key $BLOCKSCOUT_API_KEY
+    --verifier blockscout \
+    --verifier-url https://explorer-sepolia.inkonchain.com/api \
+    --verifier-api-key $BLOCKSCOUT_API_KEY
 ```
 
+> **Note:** `BLOCKSCOUT_API_KEY` can be obtained from the [Ink Blockscout explorer](https://explorer-sepolia.inkonchain.com).
+> Using `--etherscan-api-key` here will fail with an "unsupported chain" error.

 ## Additional Configuration
 
 You can customize your Foundry setup in `foundry.toml`:
