Here's a list of blockchain explorers that you can use to explore ZetaChain testnet:
ZetaScan is a blockchain explorer maintained by the ZetaChain team. You can view recent ZetaChain transactions and track the status of cross-chain transactions end-to-end. Check it out: https://explorer.zetachain.com.
Verifying Smart Contracts
ZetaScan allows you to verify the source code of deployed smart contracts and interact with them directly from the explorer.
To verify a smart contract, navigate to the contract's page and click the "Verify & Publish" button. You will need to provide the contract's source code and metadata file.
Let's compile, deploy and verify one of the example contracts as an example.
Clone the example contracts repository and navigate to the withdraw contract:
git clone https://github.com/zeta-chain/example-contracts
Install the dependencies:
Clear the cache and artifacts, then compile the contract:
npx hardhat compile --force
Create a wallet:
npx hardhat account --save
Request testnet ZETA tokens:
npx hardhat faucet
Deploy the compiled contract to ZetaChain's testnet:
npx hardhat deploy --network zeta_testnet
Follow the link in the output to view the contract on ZetaScan. Please, note that it may take a few minutes for the contract to appear on ZetaScan.
Click the "Verify & Publish" button. You will need to provide the contract's source code and metadata file.
The source code of the contract is contained in the
file. Drag the file into the drop zone in ZetaScan.
The metadata is contained in the
artifacts/build-info directory. Drag the JSON
file into the drop zone in ZetaScan as well.
After both the source code and metadata have been uploaded, click the "Verify & Publish" button. If your contract imports other contracts, you may see a pop-up window asking you to select which contract you want to verify.
Select "Withdraw" and click "Verify again".
Congratulations! Your contract is now verified on ZetaScan. You can now interact with it directly from the explorer.
