 ## What
 
 This plugin helps you verify the source code for your Solidity contracts. At the moment, it supports [Etherscan](https://etherscan.io)-based explorers and explorers compatible with its API like [Blockscout](https://www.blockscout.com/).

+### Verifying on Sourcify
+
+To verify a contract using Sourcify, you need to add to your Hardhat config:
+
+```js
+sourcify: {
+  enabled: true,
+}
+```
+
+and then run the `verify` task, passing the address of the contract and the network where it's deployed:
+
+```bash
+npx hardhat verify --network mainnet DEPLOYED_CONTRACT_ADDRESS
+```
+
+**Note:** Constructor arguments are not required for Sourcify verification, but you'll need to provide them if you also have Etherscan verification enabled.
+
+To disable Sourcify verification and suppress related messages, set `enabled` to `false`:
+
+```js
+sourcify: {
+  enabled: false,
+}
+```
+
 ### Using programmatically
 
 To call the verification task from within a Hardhat task or script, use the `"verify:verify"` subtask. Assuming the same contract as [above](#complex-arguments), you can run the subtask like this:
