    Principle of operation

    Gravity is a Token Bridge that locks tokens in the escrow contracts on Ethereum and mints tokens on Cosmos. The cross-chain communication is achieved using Gravity Bridge Blockchain with validators watching Ethereum network for events and minting tokens on Cosmos. Validators also approve transfers back to Ethereum via message signing.

    Transfers are externally verified

    Transfer events on Ethereum are being watched by Validators and when they happen tokens are minted on Cosmos. When bridging back to Ethereum the message is signed by the previously mentioned blockchain and relayed to the Ethereum network where it is checked. If everything is correct the funds are released and send back to the user.

    Destination tokens

    Note: This section requires more research and might not present accurate information.

    Tokens transferred end up as wrapped ERC20 proxies.


    The system uses the following set of permissioned addresses:

    Cosmos Validators

    Control Gravity contract on Ethereum, funds cannot be transfer without the signature of at least 2/3 of the validators set.

    Smart contracts
    Note: This section requires more research and might not present accurate information.

    The system consists of the following smart contracts on the host chain (Ethereum):

    Contract holding locked assets and handling user interactions for transfers and withdrawals. This contract stores the following tokens: USDC, WETH, DAI, USDT, WBTC.
