About Darwinia Network

GitHub | Website | Medium | Twitter | Telegram

Darwinia is a cross-chain messaging infrastructure, which provides a light client-based, programmable, universal cross-chain messaging network for decentralized applications. Now, we’ve successfully used Darwinia’s light-client cross-chain messaging protocol(LCMP) to bridge cross-chain messages between substrate-based chains, and even between substrate-based chains and EVM chains, meanwhile, Darwinia provides developers with an SDK, so they can easily integrate cross-chain capabilities into their Dapps. This will have profound implications for cross-chain interoperability, and Darwinia as a cross-chain messaging infrastructure will facilitate the building of a hybrid cross-chain network for Polkadot.

Crab is a canary network with real economic value for Darwinia, positioning similar to Polkadot’s Kusama Network, which is a programmable cross-chain platform for Dapps. It is substrate-based, EVM-compatible, and connected to Kusama.
