Live on our test network Unstablenet: a platform for testing out smart contracts
Introducing Unstablenet: A Revolutionary Testnet for the Future of Web3
Shardeum is launching a new testnet called Unstablenet on July 24, 2025. This dedicated smart contract testing environment is designed to revolutionize the development of decentralized applications (dApps) and smart contracts on Shardeum’s Ethereum Virtual Machine (EVM)-compatible blockchain.
A Sandbox for Innovation
Unstablenet provides a safe platform for developers to build, break, and optimize smart contracts and dApps before deployment on the mainnet. This sandbox environment reduces risks and bugs, making it easier for developers to create and refine their projects before they reach the wider ecosystem.
EVM Compatibility for Seamless Transition
By being fully compatible with the Ethereum Virtual Machine, Unstablenet enables developers familiar with Ethereum tooling to easily port or create applications for Shardeum’s chain without needing to learn new languages or frameworks.
Autoscaling and Sharding for Enhanced Performance
Shardeum’s blockchain offers linear scalability with low, predictable transaction fees (under $0.01) and no network congestion burden. Unstablenet allows developers to test these performance benefits for their dApps in a realistic environment. Moreover, Unstablenet is the first sharded blockchain with native EVM support, setting Shardeum apart as a pioneer in this field.
A Growing Community
With an active community of over 1 million users, Unstablenet offers developers the chance to prepare their applications for a user base ready for acquisition on a low-cost, scalable, and developer-friendly platform.
Testing Ground for Future Features
Unstablenet is expected to run long-term and continue to serve as a space for early previews of upcoming features and ongoing testing. This ensures that developers have access to the latest tools and updates as they are rolled out progressively by the tech team.
Participating in Unstablenet
Users can contribute to Unstablenet by deploying and testing Solidity smart contracts, evaluating smart contract interactions, and participating in quests, interactive dApp contests, and bounties. Rewards for participation and contributions will be announced in advance.
Accessing Unstablenet
Users can interact with the Unstablenet network using a wallet like MetaMask and RPC details provided. Additionally, users can claim test SHM tokens through a faucet channel on Discord. Bugs can be reported and feedback provided through a bug reporting channel on Discord as well.
Embracing the Future of Web3
Together, the community and the team aim to redefine what's possible in Web3 through Unstablenet. With its focus on creating great user experiences without network congestion and unpredictable gas fees, Unstablenet is set to help developers build on the world’s first autoscaling Layer 1 blockchain.
For updates on Unstablenet and further announcements, follow the website’s official social channels. Support for community-run nodes is also on the roadmap for Unstablenet.
