About Darwinia Network

Darwinia Network is a decentralized cross-chain bridge network building on Substrate, which is the “cross-chain bridge hub” of the Web 3.0 Metaverse. It provides a safe and general bridging solution, connects to Polkadot, Ethereum, TRON, and other heterogeneous chains by cross-chain transfer of assets and remote chain calls.

Darwinia Network has gained high reputation and recognition along the way to build the decentralized cross-chain bridge protocol. In 2020, Darwinia was written in Polkadot light-paper as one of the friends of Polkadot and Substrate. And Darwinia was selected to join Substrate Builder Program and Web3.0 Bootcamp, and for the outstanding work in Substrate Builder Program, Darwinia Network was officially awarded the Level 2 badge by Parity. The products and tools developed by Darwinia have been rewarded three W3F Grants.

Darwinia has been contributing to the compatibility and interoperability of the Metaverse.

The application areas of Darwinia Network include DeFi, cross-chain NFT trading, games, etc. Darwinia also develops the Metaverse game Evolution Land.
