What is ICE?

ICE is an extension network and application hub of the ICON ecosystem.
Built with Substrate, ICE is the first network to use the Substrate SDK to extend the feature-set of an existing layer one blockchain protocol. In addition, ICE will provide the much-needed addition of EVM compatibility to the ICON ecosystem.
Finally, ICE is the only EVM-compatible parachain that is also optimized for ICON’s BTP. This will position ICE as a potential flagship chain within the Polkadot ecosystem that showcases industry-leading cross-chain applications — all powered by ICON’s BTP.

Key Features

EVM & eWASM Compatible: ICE is fully EVM compatible, enabling developers to iterate and innovate much faster using existing tooling and code from the Ethereum ecosystem. ICE is also compatible with WebAssembly, a widely supported, high-performance standard that will likely serve as the foundation of decentralised systems development.
Integration with the Polkadot ecosystem: As a candidate for a Polkadot parachain, a successful auction will ensure ICE enjoys all the benefits of the Polkadot ecosystem. Powered by Substrate: ICE is built on Substrate, an open-source blockchain development framework that powers a variety of top projects including Polkadot, Kusama, Chainlink, Moonbeam, and more. Substrate allows developers to easily and efficiently build projects that are automatically optimized for any use case without requiring forks.
Access to a Multi-chain Ecosystem: As a key connection between the ICON and Polkadot ecosystems, ICE will also provide developers with unmatched access to ICON BTP partners (including Algorand, Binance Smart Chain, Polkadot and Kusama ecosystems, Harmony, and Near), as well as their respective communities.
