Develop for Ethereum Classic

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

The Ethereum Classic blockchain is ideal for application developers looking for a reliable, fast, and low cost public blockchain to deploy decentralized applications (dapps). Ethereum Classic is a secured by a large global network of miners and is one of the most highly valued blockchain networks. The native cryptocurrency, ETC, is a well-known store-of-value, which makes it a great DeFi platform. Compared with Ethereum (ETH), Ethereum Classic (ETC) is much less congested and hence much faster. For developers and users, paying blockchain "gas" using ETC costs only about 5% of ETH gas.

To develop decentralized applications (dapps) on Ethereum Classic using BUIDL is as simple as 1-2-3.

Step1 Configure BUIDL for Ethereum Classic

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

https://buidl.secondstate.io/etc

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

Setting	Value
ES Provider Endpoint	https://etc.search.secondstate.io
Web3 Provider Endpoint	https://www.ethercluster.com/etc
Chain ID	61
Custom Tx Gas	Checked
Gas Price	3000000000
Gas Limit	5000000

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.

Furthermore, since the Ethereum Classic requires bytecode generated from Solidity compiler version 0.4.2, you will need to append a /?s042 URL parameter to BUIDL. All these are done for you at https://buidl.secondstate.io/etc

Step 2 Get some ETCs for gas

In the Accounts tab, you will see 5 auto-generated ETC 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 ETC (0.1 ETC is enough) into that account to pay for gas fees.

If you do not have ETC and do not know where to buy it, send an email with your Accounts screenshot and your default address to [e-mail], and we will send you 0.1 ETC.

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.

Getting started

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 Classic!
