- Hedera has launched a browser-based Contract Builder tool for developing, testing, and deploying smart contracts on its network.
- The Contract Builder allows users to author, compile, deploy, verify, and call Solidity smart contracts directly from a web browser.
- The tool supports industry standards like ERC-20, ERC-721, ERC-1155, and Hedera Token Service (HTS) system contracts.
- No local installation or environment setup is necessary, enabling rapid prototyping and collaboration.
- The tool is open-source and built in partnership with Kabila to encourage developer contributions.
Hedera has unveiled its new Contract Builder, a web-based tool designed to simplify the development and deployment of smart contracts on the Hedera network. The Contract Builder, available through the user’s browser, aims to make it easier for both new and experienced developers to create and manage smart contracts without the need for complex setups or installations.
According to Ed Marquez and Manu Cabrera, the Contract Builder enables users to start authoring and deploying smart contracts within seconds. The tool provides built-in templates and supports well-known blockchain standards, including ERC-20 (used for fungible tokens), ERC-721 (non-fungible token standard), and ERC-1155 (multi-token standard), in addition to Hedera Token Service (HTS) contracts. These features allow developers to interact with common contract types and test logic easily.
Users can author Solidity contracts by selecting functions and properties, compile them directly in the browser, and deploy to the Hedera test network with a single click. Verification is enabled through Sourcify on HashScan. The tool also allows for execution of contract functions to confirm behavior, as well as collaboration and sharing among peers.
The browser-based tool eliminates the need for users to download software, run local nodes, or switch between different development environments. Hedera states that even those with minimal Solidity experience can use the Contract Builder’s interactive templates and real-time feedback to begin learning about smart contracts and decentralized application development.
The Contract Builder is open source and developed with the support of Kabila, a Hedera ecosystem project that focuses on both Web2 and Web3 technologies. The open-source model encourages transparency and community-driven improvements, allowing contributors to expand the platform’s features collaboratively.
Getting started with the Contract Builder requires logging in to a Hedera Portal account. Once logged in, users can select templates or standards, author their contracts, then compile, deploy, and verify them directly from the browser interface. The process is intended to reduce barriers for those entering Web3, especially for developers transitioning from traditional software backgrounds.
Hedera has positioned the tool as a way to make building and experimenting with smart contracts more efficient while encouraging wider adoption within its developer community. Full details and the Contract Builder tool are available at hedera.com/contract-builder. Developers are invited to share feedback on the official Hedera Discord.
