Gravity Bridge node is the gravity daemon that runs the Cosmos to Ethereum bridge, written for developers, validators and advanced users who want to connect Cosmos SDK chains such as the Cosmos Hub with Ethereum. It is a free, open source program in the nodes and blockchain clients category, and its latest release is v1.14.4.
The project focuses on keeping its design simple and efficient, so the software does one job: moving assets between the two ecosystems. Its code was last updated on September 25, 2026, which means the project is actively maintained at the time of writing. Because it is a node rather than a point-and-click app, expect to work in a terminal. The guide below covers what the program does, how to install it on Windows, and how it compares with other clients.
What Is Gravity Bridge Node?
Gravity Bridge node is the software that runs the gravity daemon, the process that keeps a machine connected to the bridge network. A node is not the same thing as a wallet. A wallet stores keys and lets you send funds, while a node keeps a copy of the chain and checks its data against the rules of the network.
The word bridge describes the purpose. Blockchains such as Cosmos and Ethereum use different rules and different token standards, so they cannot read each other's transactions directly. A bridge is the connecting layer that lets assets and messages pass between them. Gravity Bridge focuses on the Cosmos to Ethereum direction and uses the Cosmos SDK as its foundation.
For most readers, the practical takeaway is that this is infrastructure software. It is meant to run continuously on a server or a dedicated PC, and it is most useful to people who want to understand how cross-chain systems work from the inside.
How a Cosmos to Ethereum Bridge Works
Bridges generally rely on participants that observe events on one chain and act on the other. Validators are participants whose signatures or votes count toward a decision. Relayers are processes that carry data between networks, so a transfer can be recorded on both sides.
In many bridge designs, assets are locked on the source chain while a representation is issued on the destination chain. The reverse happens when the asset returns. The exact steps depend on each bridge's rules, so the project's documentation is the place to confirm the flow for this software.
Two terms come up often. Finality describes the point after which a transaction is considered settled and is very unlikely to be reversed under normal conditions. Consensus is the process by which the network agrees on the order and validity of transactions. Understanding both helps you read the node's logs and sync status with more confidence.
Real-World Scenarios for a Bridge Node
A developer building a cross-chain application might run the node on a local machine to test how messages move between Cosmos and Ethereum. Testing on a separate setup keeps experiments away from any live data and makes it easier to reset the environment when something goes wrong.
An infrastructure team might run the node as part of a larger service that monitors bridge activity. In that case, logging, disk monitoring and scheduled restarts matter as much as the software itself. Good operators document their configuration so that a colleague can recover the setup quickly.
A researcher or community member might run the node mainly to study how the bridge logic is structured. Reading the open source code alongside the running daemon is a practical way to learn how Cosmos SDK chains handle cross-network communication.
Key features
Cosmos to Ethereum bridging
Built for Cosmos SDK chains
Simplicity-first design
Ethereum asset support
Free and open source
Supported coins
The project's documentation names Ethereum (ETH), Cosmos (ATOM) and ERC-20 tokens as the assets involved in the bridge. ERC-20 is a token standard used by many Ethereum projects, so the bridge is relevant to a broad group of tokens. Refer to the current documentation for details on each asset, since supported assets can change as the software evolves.
How to install Gravity Bridge node on Windows
- 1
Confirm a Windows build exists
Open the project's GitHub Releases page and look for a Windows file that matches the version you want, such as the latest v1.14.4. If no suitable file is listed, building the program yourself is a developer task that requires additional tools.
- 2
Download from the official source
Download the files only from the official website or the GitHub Releases page. Avoid mirrors and links shared in chats or forums, since they can carry modified files.
- 3
Verify the file
Compare the file's SHA-256 checksum with the value published on the release page. If a signature is provided, verify it as well. Do not run a file whose checksum does not match.
-
Extract and place the binary
Extract the archive into a dedicated folder, such as C:\gravity, so the node's files stay in one place. Add that folder to your PATH if you want to run the gravity command from any directory.
How to use Gravity Bridge node
Once installed, the gravity daemon runs from a terminal and stays open while it syncs with the network. The steps below outline a typical session. Exact commands and flags can change between releases, so read the documentation that comes with your version.
- Open PowerShell or Command Prompt and confirm that the gravity command runs and displays its version.
- Choose a home directory for node data and make sure the drive has enough free space for the chain's data.
- Configure the network settings, such as the peers the node connects to, following the project's documentation.
- Start the daemon and let it sync with the network before relying on its output.
- Monitor the log output for errors, warnings and sync progress.
- Stop the node cleanly before installing a newer release, then restart it and check the version again.
Pros & cons
- Free and open source, with public code on GitHub
- Designed around simplicity and efficiency
- Covers the Cosmos to Ethereum link, including ETH and ERC-20 assets
- Built for Cosmos SDK chains such as the Cosmos Hub
- Recently updated, with v1.14.4 as the current release
- Windows availability depends on the release, so check before installing
- Command-line focused, which suits operators more than casual users
- Narrow scope: it handles the bridge, not wallet or trading tasks
- Running a node requires ongoing attention to updates, disk space and logs
Is Gravity Bridge node safe?
Gravity Bridge node is infrastructure software, so treat it with the same care as any program that touches blockchain keys. Download it only from the official website or the GitHub Releases page, and check the SHA-256 checksum or signature before running the file. Never enter a seed phrase on third-party websites, and never type it into a program that asks for it unexpectedly. If your node uses validator or signing keys, store the key files offline or in encrypted storage, and do not share them with anyone. The code was last updated on September 25, 2026, so check the latest version, currently v1.14.4, on the official website before you install, and keep the node updated.
- Official source only. Download from github.com/gravity-bridge/gravity-bridge. Ignore ads and lookalike domains.
- Check the SHA-256. Compare the installer hash with the value the developer publishes before running it.
- Never share your seed phrase. No developer, support agent or website — including CryptApps — will ever ask for it.
Alternatives
Gravity Bridge node sits in a different place from most entries in this category. Geth, Nethermind and Erigon are full Ethereum clients that sync and verify the Ethereum chain itself. Evmos runs an EVM-compatible chain inside the Cosmos ecosystem, while Celestia App handles consensus for the Celestia network. Gravity Bridge is narrower: its job is the link between Cosmos and Ethereum. If you want to read Ethereum state, a client such as Geth is the better fit. If you need the bridge itself, Gravity Bridge is the relevant choice. GoQuorum is not supported, and OpenEthereum has closed, so neither is a good option for a new setup.

Frequently asked questions
Gravity Bridge node runs the gravity daemon, which connects the Cosmos ecosystem with Ethereum. It is aimed at developers, validators and operators who want to take part in bridge activity between Cosmos SDK chains such as the Cosmos Hub and Ethereum. Unlike a wallet, it is infrastructure software, so it is most useful when you need to run a node rather than simply hold or send tokens.
Yes. Gravity Bridge node is listed as free and open source, and its source code is published on GitHub. You can get the ready-made program from the project's release files without paying a license fee. Running any node still uses your own hardware, electricity and internet connection, and those costs are yours to carry.
The project builds for Windows, but availability can differ between releases. Check the Releases page for a Windows file that matches the version you want. If no suitable file is posted, you would need to build the program yourself, which is a more advanced process. Review the release notes before you start.
It can be, provided you take normal precautions. Verify the file's SHA-256 checksum or signature, keep the software updated to the latest release, and protect any keys the node uses. The safety section explains each step in more detail. Never enter a seed phrase on a third-party website, even if the page looks official.
The project's documentation names Ethereum (ETH), Cosmos (ATOM) and ERC-20 tokens as the assets involved. ERC-20 covers many tokens built on Ethereum, so the bridge is relevant to a broad group of assets. Check the current documentation for details on each one, since supported assets can change as the project evolves.
Yes, based on its recent activity. The latest code update was made on September 25, 2026, and the current release is v1.14.4. Active maintenance makes fixes more likely, but it does not guarantee future releases, so review the repository's activity before you depend on the software for important work.
Verdict
Gravity Bridge node suits developers, validators and infrastructure operators who want a focused client for the Cosmos to Ethereum link. It is free, open source and recently updated, and its design goals center on simplicity and efficiency. It is a poor fit for anyone who wants a point-and-click app or general crypto management. If you only need an Ethereum client, a tool such as Geth may be simpler. If your work is in the Cosmos SDK ecosystem, this node is the more relevant choice.
