  1. Contract Verification

What's Contract Verification

Last updated 8 months ago

Contract verification is essentially open-sourcing your contract code

Contract verification allows smart contract developers to prove and publish the source code of the contracts deployed on-chain .

You may have come across some of them when browsing the of any contract address on Etherscan.

How do I verify a contract I've deployed ?

If you've deployed your contract using an online tool such as Remix, or OpenZeppelin's Contract Wizard, consider using the page.

If you've deployed your contract using a development tool such as Hardhat, Foundry, Truffle and so on, consider using to automate the verification process.
