A browser-based tool for editing, compiling, deploying, verifying, and calling smart contracts on Hedera in seconds.

What is the Hedera Contract Builder?

The Hedera Contract Builder is a powerful new tool for developers that makes it easier than ever to work with smart contracts on Hedera. Whether you’re just starting with Solidity or you're an experienced developer looking to prototype quickly, the Contract Builder provides everything you need right in your browser.

There’s no need to install packages, configure local nodes, or juggle with environments. With just a few clicks, you can author, compile, deploy, verify, and call Solidity smart contracts on the testnet. And with built-in templates and support for well-known standards like ERC-20, ERC-721, and HTS, it’s the fastest way to bring your smart contract ideas to life.

The Contract Builder simplifies the end-to-end contract development process, enabling you to:

• Author Solidity smart contracts by selecting the functions and properties you want

• Compile contracts directly in the browser

• Deploy contracts to the Hedera testnet with a single click

• Verify contract code using Sourcify on HashScan

• Execute contract functions to test your logic

• Share your contracts with collaborators

With support for HTS system contracts and widely-used standards like ERC-20, ERC-721, and ERC-1155, the Builder accelerates your flows, from learning Solidity to testing token logic. Whether you’re exploring with smart contracts for the first time or validating a new idea, the Builder is your sandbox.

The Playground is an open-source project built in collaboration with Kabila, a project in the Hedera ecosystem with expertise in Web2, Web3, and Hedera technologies. The open-source nature of the Builder facilitates transparency and encourages contributions from the developer community.

Who is it for?

Web2 Developers:

The Hedera Contract Builder is a great first step into Web3. If you’re a Web2 developer curious about smart contracts or decentralized applications, this tool eliminates the typical barriers like complex setups, and unintuitive command-line tools, and lets you jump straight into writing and deploying contracts. With minimal Solidity knowledge, you can start learning and experimenting using interactive templates and instant feedback.

Existing Hedera and Web3 Developers:

For developers already building on Hedera or familiar with EVM-compatible platforms, the Contract Builder is a productivity booster. It enables rapid prototyping, instant deployments, and quick iterations to help you explore your best ideas. Test new contract logic or explore Hedera’s smart contract capabilities in seconds, without having to spin up a full dev environment.
