Once deployed, a contract resides at a specific address on the Ethereum blockchain. A contract is a collection of functions and data (its state). Defines a contract named `HelloWorld`. Specifies the version of Solidity, using semantic versioning. So if we convert 0x2B5E3AF16B1880000 to decimal we get 5*10^18 which equals 5 eth. The conversion from wei to eth is: 1 eth = 10^18 wei. Wei is used as the smallest denomination of ether. CODE language-js line-numbers - NOTE: This result is in wei not eth.

Check out this video for instructions on how to use the composer tool!Īfter you input your Metamask account address and click “Send Request”, you should see a response that looks like this: This will return the amount of Eth in our wallet. To double check our balance is there, let’s make an eth_getBalance request using Alchemy’s composer tool. (At the time of writing this, it took around 30 minutes.) You should see Eth in your Metamask account soon after! Step 5: Check your Balance To get Eth you can go to the Goerli faucet and enter your Goerli account address, then click “Send Me Eth.” It may take some time to receive your fake Eth due to network traffic. In order to deploy our smart contract to the test network, we’ll need some fake Eth. Navigate to the “Create App” page in your Alchemy Dashboard by hovering over “Apps” in the nav bar and clicking “Create App” If you’re not familiar with testnets, check out this guide. This will allow us to make requests to the Goerli test network. Once you’ve created an Alchemy account, you can generate an API key by creating an app.

If you don’t already have an Alchemy account, sign up for free here. The platform also has developer tools for monitoring and analytics that we’ll take advantage of in this tutorial to understand what’s going on under the hood in our smart contract deployment.
For simplicity, we’ll use a free account on Alchemy, a blockchain developer platform and API that allows us to communicate with the Ethereum chain without having to run our own nodes. There are many ways to make requests to the Ethereum chain.
