To deploy a smart contract, you merely send an Ethereum transaction containing the compiled code of the smart contract without specifying any recipient. Prerequisites You should understand Ethereum networks , transactions and the anatomy of smart contracts before deploying smart contracts. Deploying a contract also costs ether ETH , so you should be familiar with gas and fees on Ethereum.
Finally, you'll need to compile your contract before deploying it, so make sure you've read about compiling smart contracts. How to deploy a smart contract What you'll need your contract's bytecode — this is generated through compilation ETH for gas — you'll set your gas limit like other transactions so be aware that contract deployment needs a lot more gas than a simple ETH transfer a deployment script or plugin access to an Ethereum node , either by running your own, connecting to a public node, or via an API key using a node service like Infura or Alchemy Steps to deploy a smart contract The specific steps involved will depend on the tooling you use.
If the contract compiles perfectly, you will see a green tick with the solidity icon as shown in the image above. Bookmark for later: How does Ethereum work? After deploying the contract you will see your contract under the deployed contracts as shown in the image above. Now we can test the smart contract by updating the num variable. Updating the variable We can update the num variable, using the setNum function by entering an integer value as shown below and then clicking on setNum in orange color.
This will store the integer value, that we enter inside the num variable. Now you can check the value of the variable by clicking on num in blue color. The value stored inside num will be displayed below it as shown in the image above. You have built and tested a smart contract on Remix IDE.
