Gravity Bridge is a decentralized, open-source blockchain interoperability solution designed to connect the Cosmos ecosystem with Ethereum. It enables seamless transfer of assets such as ERC20 tokens (e.g., DAI, USDC) from Ethereum into Cosmos-based blockchains and vice versa, allowing Cosmos assets like ATOM to be represented and traded as ERC20 tokens on Ethereum decentralized exchanges and DeFi platforms. The bridge leverages the Inter-Blockchain Communication (IBC) protocol to facilitate cross-chain communication and asset transfers without requiring each Cosmos chain to operate its own bridge infrastructure.
The core of Gravity Bridge is built on Cosmos SDK and integrates Ethereum smart contracts to lock and mint tokens securely. Validators observe events on both chains and relay proofs to ensure trustless asset transfers. The system supports bidirectional transfers: locking Ethereum assets to mint Cosmos representations and burning Cosmos assets to release Ethereum tokens. The bridge also includes modules like the Gravity Auction Module for decentralized token distribution and supports integration with Ethereum AMMs and DeFi protocols.
Developers can integrate Gravity Bridge by deploying the Peggy modules into their Cosmos-SDK chains or using the provided demo application. Setting up involves running the bridge chain, deploying Ethereum contracts, and operating relayers that monitor and relay cross-chain events. The project provides comprehensive documentation, including setup guides for local testing, Ropsten testnet integration, and relayer operation. Gravity Bridge aims to enhance liquidity and interoperability between Ethereum and Cosmos ecosystems, enabling new DeFi composability and asset portability. Getting started requires familiarity with Cosmos SDK, Ethereum smart contracts, and running validator nodes or relayers.
Cross-chain asset transfers between Ethereum and Cosmos ecosystems are complex due to incompatible protocols and lack of a unified bridge infrastructure. This fragmentation limits liquidity and DeFi composability across these networks.
Modular bridge components that can be integrated into any Cosmos-SDK based blockchain.
Smart contracts on Ethereum handle locking and minting of ERC20 tokens representing Cosmos assets.
Relayers monitor blockchain events and submit proofs to facilitate cross-chain asset transfers.
Enable Cosmos assets like ATOM to be used as ERC20 tokens on Ethereum DeFi platforms such as Uniswap.
Allow projects built on Cosmos SDK to access Ethereum liquidity and vice versa without centralized intermediaries.
Use the Gravity Bridge Auction Module for user-driven, decentralized token sales and distribution across chains.
