The Gravity Bridge chain serves as a neutral bridge between Ethereum and Cosmos. With the help of IBC (Interblockchain communication), various Cosmos-based projects can connect to and utilize the bridge to access ERC20 assets such as dai or usdc, without the need to operate the gravity orchestrator on their own chain. Gravity enables the transfer of ERC20 assets from Ethereum to Cosmos and vice versa, allowing assets like ATOM and other Cosmos ecosystem assets to be traded on Uniswap and other Ethereum AMMs, as well as interact with Ethereum DeFi just like any other ERC20 token.
