Building a smart contract is an essential part of the creative project that leads to a dApp for Chiliz Chain — or any blockchain, really.

There are two steps that you must go through once you have built your dApp's smart contract:

1. Deploying the contract on Chiliz Chain.

2. Verifying that contract.

These two steps are documented here.

To ensure that your transaction doesn't remain in "pending" status for too long, you should include enough to cover the fees:

• Minimum gas fee: 2,500 gwei.

• Minimum priority fee: 1 gwei.

Step 1: Deploy your smart contract

You can use either of these options:

Deploy with RemixDeploy with thirdweb

Step 2: Verify your smart contract

After creating a smart contract, it is necessary to verify it. Only you can do it, and you should do it as soon as possible.

Here are guides for each:

Verify with ChiliscanVerify with Chiliz Block Explorer

Once your contract is verified, it will receive a "green dot" on the block explorer interface, indicating that your contract can be trusted.
