# What's Contract Verification

> Contract verification is essentially **open-sourcing** your contract code :pencil2:

Contract verification allows smart contract developers to prove and publish the **source code** of the contracts deployed on-chain :white\_check\_mark: .

You may have come across some of them when browsing the [**Contract tab**](https://xdc.blocksscan.io/address/0x5d5f074837f5d4618b3916ba74de1bf9662a3fed?tab=contract#code) of any contract address on XDC BlocksScan Explorer.

## How do I verify a contract I've deployed ? <a href="#how-do-i-verify-a-contract-ive-deployed" id="how-do-i-verify-a-contract-ive-deployed"></a>

If you've deployed your contract using an online tool such as Remix, or OpenZeppelin's Contract Wizard, consider using the [**contract verification**](https://xdc.blocksscan.io/contracts/verify) page.

If you've deployed your contract using a development tool such as Hardhat, Foundry, Truffle and so on, consider using [**plugins**](https://docs.blocksscan.io/contract-verification/contract-verification-plugins) to automate the verification process.
