What Gravity Bridge does
Gravity Bridge is a purpose-built, fully decentralized blockchain that bridges assets between the Ethereum and Cosmos ecosystems. Its architecture comprises four components: the Gravity.sol Ethereum contract that locks ERC20 tokens, a Cosmos SDK module that mints corresponding Cosmos-side tokens, an orchestrator run by validators to sign cross-chain messages, and a free-market relayer layer. The platform uses the full Cosmos validator set (over 100 validators at mainnet launch) for security, with slashing and three pre-launch audits (Code4Arena, Informal Systems, Least Authority). Since its decentralized mainnet launch on December 13, 2021, it has become the most widely adopted bridge in Cosmos, connected to over half of IBC-enabled chains.
The product surface has expanded beyond fungible token bridging to include the Interchain Accounts (ICA) Controller Module, which lets users execute swaps on Osmosis and Crescent DEX from Gravity, an Auction Module launched in March 2024 that distributes bridge fee tokens to $GRAV holders, the Polaris upgrade adding Metamask-only ETH key signing, IBC auto-forwarding for single-transaction cross-chain UX, and an ICS721 working group building NFT bridging with Stargaze and IRISnet. A front-end toolkit enables Cosmos chains to deploy white-labelled Gravity UIs, with Nym and Persistence as adopters.
The business model is a decentralized protocol with no corporate entity, board, or disclosed institutional funding. Revenue mechanics consist of a 1 basis point fee on Cosmos-to-Ethereum MsgSendToEth transactions and 50 $GRAV fees per Auction Module bid, with bridge fees split 50/50 between stakers and a community pool. Go-to-market is product-led and community-led: permissionless integration via IBC, no gatekeeping, and governance conducted through the Commonwealth forum under a federated DAO structure (Gravity Growth) with working groups for development, marketing, ecosystem growth, and grants.

Revenue model
- Bridge Fees: Gravity Bridge collects fees on all MsgSendToEth transactions at a rate of one basis point (0.0001 of transaction value). Fees are paid in the same denomination as the token being bridged. Currently split 50/50 between Gravity Bridge stakers and the Gravity Bridge community pool.
- Auction Bid Fees: Each bid in the Auction Module incurs a fee of 50 GRAV tokens. This deters sandbaggers, bots, and auction snipers while generating additional revenue from the auction process.
Pricing tiers

Gravity Bridge product offering
Product offeringCore offering
Gravity Bridge is a purpose-built, fully decentralized, trustless blockchain that bridges assets between Ethereum and Cosmos ecosystems. It enables ERC20 tokens from Ethereum to flow into Cosmos and Cosmos SDK tokens to access Ethereum DeFi liquidity, using a combination of on-chain Ethereum contracts, a Cosmos SDK module, validator-run orchestrators, and a free-market relayer network. Supporting modules include an auction module for distributing bridge fees and an Interchain Accounts controller for cross-chain account management.
Product overview
Gravity Bridge operates as a unified blockchain bridge platform connecting Ethereum and Cosmos ecosystems. The core product is the Gravity Bridge itself—a decentralized, trustless blockchain for cross-chain asset transfer. Supporting modules include the Auction Module for decentralized token distribution, IBC Auto-Forwarding for seamless cross-chain transactions, and the ICA Controller Module for interchain account management. The platform also offers a Front End Toolkit enabling Cosmos chains to build custom interfaces, and a Snapshot Service for validator support.

Gravity Bridge competitors and assessment
Company assessmentDirect peers
- THORChain: THORChain is a decentralized liquidity network enabling native cross-chain swaps between Bitcoin, Ethereum, Cosmos, and other chains. While using a different mechanism (swaps vs. lock/mint), it competes with Gravity Bridge for cross-chain asset transfer use cases in the Cosmos-adjacent ecosystem.
- Wormhole: Wormhole is a cross-chain messaging protocol that wraps and unwraps assets across Solana, Ethereum, BSC, and other chains using a guardian network. Like Gravity Bridge, it is a lock/mint token bridge connecting heterogeneous ecosystems, making it the closest direct competitor in the bridging category.
- Stargate: Stargate is a cross-chain bridge built on LayerZero that uses unified liquidity pools for native asset transfers across chains. It competes directly with Gravity Bridge for cross-chain liquidity routing and stablecoin bridging use cases.
- LayerZero: LayerZero is an omnichain messaging protocol used to build bridges (including Stargate) connecting Ethereum, Cosmos chains, and other networks. It is a direct competitor for cross-chain asset transfer infrastructure, often preferred for new omnichain applications.
- Axelar: Axelar is a Cosmos-SDK-based interoperability network providing cross-chain messaging and asset transfer, native to the same ecosystem as Gravity Bridge. It competes head-to-head for Ethereum ↔ Cosmos bridge traffic and shared integrator relationships across IBC-enabled chains.
- Synapse Protocol: Synapse is a cross-chain bridge and liquidity network supporting Ethereum, Cosmos, and other chains. It offers token bridging and cross-chain swaps, overlapping directly with Gravity Bridge's Ethereum ↔ Cosmos asset transfer functionality.
Emerging players
- Connext: Connext is a modular interoperability protocol focused on cross-chain messaging and calldata passing between EVM chains. It is an emerging alternative for cross-chain bridging with partial overlap to Gravity Bridge's developer tooling and asset routing use cases.
- Hop Protocol: Hop Protocol is a cross-chain bridge for sending tokens between Ethereum, rollups, and sidechains using a native AMM-based bridge model. It overlaps with Gravity Bridge on Ethereum-side bridging and has expanded toward broader cross-chain reach.
Broad incumbents
- Chainlink CCIP: Chainlink's Cross-Chain Interoperability Protocol (CCIP) is a broad incumbent offering institutional-grade cross-chain messaging and token transfer. It competes in the same cross-chain infrastructure category with significantly more resources, brand recognition, and enterprise positioning.
Others
- Cosmos Hub: Cosmos Hub is the central blockchain of the Cosmos ecosystem from which Gravity Bridge rents shared security. It is an ecosystem enabler rather than a direct competitor, but its validator economics, governance, and Interchain Foundation stewardship directly influence Gravity Bridge's security model.
