Deploy Smart Contracts with Remix

Shardeum release is a phased rollout, and the initial test version of dApp & smart contract support is expected to be available in Q2 of 2025. Our aim is to work with the community to make this the fastest, parallel executing and affordable EVM platform and we can't wait to get started

Smart contracts and dApps are not yet supported on Shardeum. The beta version is expected in Q2 2025, with full launch planned for Q3 2025. We are working closely with the community to build the fastest, most affordable parallel-executing EVM platform and we can't wait to get started.

Remix IDE is an open source web and desktop application. It fosters a fast development cycle and has a rich set of plugins with intuitive GUIs. Remix is used for the entire journey of contract development as well as act as a playground for learning and teaching Ethereum.
