Which is the best way to deploy a smart contract?
Your contract is now ready, so let’s compile it. Once the contract is compiled, let’s deploy it on the blockchain. As mentioned earlier, we’ll use Kovan testnet to deploy the contract. Check if the smart contract is deployed. For the contract I deployed for this tutorial, this is the transaction.
