Live on the testnet: Unstablenet's intelligent contract platform

Experiment with deploying and examining smart contracts on our site's Unstablenet - a testnet similar to the EVM that is designed for developers to create, debug, and fine-tune Web3 applications by testing them out.

Live on the testnet: Unstablenet's intelligent contract platform

Unstablenet, a groundbreaking testnet developed by Shardeum, is set to revolutionize the world of Web3 applications and smart contracts. The ultimate goal is to enable various applications, such as machine learning models and gaming platforms, that were previously not feasible on blockchains[1].

This innovative testnet is designed for developing, experimenting, and deploying smart contracts and decentralized applications (dApps) on an Ethereum Virtual Machine (EVM)-compatible blockchain[2]. By offering an environment for early testing and experimentation with new features in a controlled, non-production setting, Unstablenet aims to empower developers and users to test, build, and innovate alongside the team[3].

The Testing Focus of Unstablenet

The primary focus of Unstablenet is to enable developers to identify bugs, optimize contract behavior, and validate functionalities in a way that mimics the mainnet but without the risks and costs associated with live deployment[1]. This helps ensure that smart contracts and dApps are robust and secure when released officially.

Unstablenet vs Mainnet

Unstablenet differs significantly from the mainnet. While the mainnet is the fully operational blockchain network where real transactions occur, and actual value is transferred and secured by full decentralization, Unstablenet is a testnet, intended for testing and development[1][3]. As such, Unstablenet is less stable by design, allowing for breaking and refinement, whereas the mainnet prioritizes stability, security, and finality.

Getting Started with Unstablenet

To start interacting with Unstablenet, users need a wallet such as MetaMask configured with specific RPC details. When adding Unstablenet endpoints to MetaMask, you may see the suggested network name as "our website Liberty 1.x". You can rename it locally as "our website Unstablenet" in your wallet settings[4].

Unstablenet features components that are being actively stress-tested by the engineering team. Fixes and feature updates will be rolled out progressively by the tech team as they are ready[5].

Future Plans for Unstablenet

Currently, there are no reward programs for contributing to Unstablenet, but incentives are planned to be introduced soon[6]. Users can deploy and test Solidity smart contracts on Unstablenet, use standard Ethereum tools, evaluate smart contract interactions, and participate in quests, interactive dApp contests, and bounties[7].

The website is launching Unstablenet on July 24, 2025[8]. After the testnet phase is successfully completed, launching smart contract functionality on the mainnet will occur[2].

For real-time updates on Unstablenet and further announcements, users are encouraged to follow the website's official social channels. The current gas estimation mechanism defaults to a fixed value of 3 million. If you encounter issues with transactions not going through, try setting a higher custom gas limit manually[9].
