Second State launches BUIDL IDE for Ethereum Classic

Share Article

Calling all developers: Ethereum Classic is the best blockchain for smart contracts and dapps. With the Second State BUIDL IDE, you can develop and deploy on ETC in minutes from any web browser. See how:

Decentralized applications (dapps) are collaborative and censorship-resistant applications built on blockchain smart contracts. Examples of popular dapps include cryptocurrencies, payments, crypto exchanges, prediction markets, peer to peer e-commerce, and decentralized finance (DeFi).

Ethereum is the world’s first and dominant smart contract platform. It has the largest dapp ecosystem with over a million deployed smart contracts and hundreds of millions of dollars in monthly transactions. However, compared with web and mobile app development, it is still very difficult for developers to get started with dapp development. Developers and users must be familiar with cryptocurrency, crypto wallet, blockchain nodes, RPC services, web3, a variety of tools, specialized programming languages, frameworks, and services. That has greatly hampered dapp adoption.

Furthermore, in the past several weeks, the Ethereum blockchain is operating near its capacity. The gas price required for developers and users to operate smart contracts is now 10x its value earlier this year, and it takes hours for a smart contract transaction to get confirmed on the network.


Ethereum Classic (ETC) is one of the most secure and decentralized blockchain networks today. It is fully compatible with the Ethereum blockchain (ETH), but is much faster (transactions are confirmed in seconds) and much cheaper (gas fee is 1% of ETH). Developers are looking at Ethereum Classic as a serious alternative to the Ethereum blockchain.

“Ethereum Classic is not only the original Ethereum blockchain,” said Elizabeth Kukka, Executive Director of Ethereum Classic Labs. “But also the most dapp friendly Ethereum blockchain with its very low gas fees, store-of-value native cryptocurrency, and fast confirmation times. We look forward to collaboration with Second State to further empower our developer communities.”

However, developer tooling on Ethereum Classic has been traditionally lacking, and as a result, far fewer smart contracts and dapps are deployed on Ethereum Classic. Second State aims to change that.


The Second State BUIDL IDE (Integrated Development Environment) is a web-based IDE that requires no software download or install. It provides a one-stop development and deployment environment for smart contract and dapp developers. With one click, developers can publish a dapp on the web for everyone to interact with blockchain smart contracts. Watch the short video tutorial to see how to create a wallet-free, cryptocurrency-free and wait-free dapp on BUIDL.

Bob Summerwill, Executive Director of the ETC Cooperative, said “I am delighted to see Second State launch BUIDL for ETC. There has been a developer need for such a tool since the death of the much beloved Ethereum Studio many years ago. It is marvelous to see Second State launching BUIDL for ETC to fill this need, and to help provide an easier onramp for developers to develop on ETC.”

Working with ETC Labs and ETC Cooperative, Second State has released a special version of its BUIDL IDE for the Ethereum Classic blockchain. Developers can now develop and deploy in the Ethereum Classic blockchain in minutes from any web browser with no software to download or install.

1 Open the BUIDL for ETC IDE via the following link:

2 Open the Accounts tab and send a little ETC (0.1 ETC) to the default address to use as gas for deployment on the Ethereum Classic blockchain. If you do not know how to get ETC, send an e-mail to to ask for some.

3 Develop, debug, deploy, and publish your dapp! Learn more:
