Develop for Ethereum

Use the BUIDL IDE to create and deploy applications on the Ethereum blockchain

The Ethereum blockchain is the most widely used blockchain smart contract platform. However, it is also heavy congested and very expensive to deploy and run decentralized applications (dapp). For Ethereum application developers, we recommend you to develop and run your applications on Ethereum Classic or CyberMiles instead.

That said, to develop decentralized applications (dapps) on Ethereum using BUIDL is as simple as 1-2-3.

Step1 Configure BUIDL for Ethereum

The easy way is to just click the link below to launch BUIDL in your browser. It pre-loads all the configurations for you.

Of course, you can also manually setup the configurations from the Providers tab at the lower left panel of BUIDL.

Chain ID

Custom Tx Gas

Checked

Gas Price

10000000000

Gas Limit

8000000

The gas price and limit are the default values when you use BUIDL to deploy or call contracts. They are also used when you call web3.ss functions in the JavaScript application without specifying gas.

Step 2 Get some ETHs for gas

In the Accounts tab, you will see 5 auto-generated ETH addresses, and you can set any of them as default. The default address is used to sign transactions from both BUIDL and web3.ss applications. Because of that, you will need to send a little ETH (0.1 ETH is enough) into that account to pay for gas fees.

Step 3 Develop and deploy

You can now follow the Getting Started guide to develop and deploy your smart contract and dapp. The web3.ss package is a fully featured replacement for the web3.eth package. Of course, in your JavaScript code, you can still use web3.eth if you wish.

The contract creation, and function calls are all executed with the gas price and gas limit you set. You can still specify the gas price and limit on a per transaction basis. Here is an example.

instance.set(n, {
gas: 100000,
gasPrice: 10000000000
}, function (e, result) {
// ... ...
});

That's it. Happy coding on Ethereum!
