Ambire is a free, open-source Ethereum wallet for people who want to hold and manage their own keys from a web browser. It is built around Ethereum and EVM-compatible networks, and it suits anyone who prefers to control their funds directly rather than leave them with a service.
Ambire is self-custodial, which means the project never takes custody of your funds and does not act as a counterparty to any trade. Ambire for Windows is delivered as a browser extension, not a standalone desktop program. The same project also has versions for macOS, Android, iOS, Docker and the web, but on a Windows PC you work with the extension inside Chrome, Edge or Firefox.
What Is a Self-Custodial Wallet?
A self-custodial wallet stores the cryptographic keys that prove ownership of your funds on your own device, not on a company's server. When you send a transaction, the wallet signs it locally with your private key and broadcasts it to the network.
The practical consequence is that nobody can reset your password or recover your funds for you. Your seed phrase, a list of words generated when you create a wallet, is the master backup. Anyone who gets that phrase can take control of the funds, and if you lose it, the funds may be unrecoverable.
This model is different from a centralized exchange, where the company controls the balances. Ambire follows the self-custodial model, so the responsibility for backups and everyday security sits with you.
Who Ambire Is For
Ambire fits Windows users who already spend time in a browser and work with Ethereum or EVM networks. Typical users include people who want to hold Ethereum-based assets, developers who test decentralized apps, and users who want a Ledger device for signing.
It is also a reasonable choice for readers who care about open source. Because the code is public, technically minded users can review how the wallet works before trusting it with funds.
It is less suited to people who want a full desktop application, or who need a wallet that covers many non-EVM blockchains. Those users may prefer one of the alternatives listed below.
Common Use Cases for an Ethereum Browser Wallet
A typical day with an Ethereum browser wallet might involve checking a token balance, sending ETH to a friend, or approving a request from a decentralized application. Each action is signed by you, so the wallet confirms what you are authorizing before anything leaves your account.
Every Ethereum transaction pays a gas fee to the network. Gas fees change with network demand, so the cost of the same transfer can differ from one day to the next. Reading the fee before you confirm is a simple habit that avoids surprises.
Some wallet features depend on third-party services. In those cases, the provider's own documentation and terms apply, and any fee is documented for that feature. Read those details before using the service, especially when it involves swaps or external platforms.

How to install Ambire on Windows
- 1
Get the Official Package
Download Ambire only from the official website at ambire.com or from the Releases page of the AmbireTech/extension repository on GitHub. Ignore search ads and links shared in chats, because copies of wallet software are a common phishing tactic.
- 2
Verify the File
Compare the file's SHA-256 checksum with the value published alongside the release. If a signature is provided, check it as well. If the values do not match, delete the file and do not install it.

Add the Extension to Your Browser
Install the extension in Chrome, Edge or Firefox using the browser's standard extension installation process. Open the extension, create a new wallet or import an existing one, and write down your seed phrase offline before you deposit any funds.
How to use Ambire
Setting up Ambire takes only a few minutes, but the first session matters most. Work through these steps in order:
- Open the extension from your browser toolbar and choose whether to create a new wallet or import an existing one.
- Write your seed phrase on paper and store it somewhere offline. Never type it into a website, a form or a chat.
- Set a strong password for the extension on this computer.
- If you use a Ledger, connect the device, unlock it and select the Ledger option when the wallet asks how to sign.
- Check that the network you need is selected, starting with Ethereum, and confirm your balance looks correct.
- Send a small test amount before moving larger sums.
- When a website asks to connect, read the request and approve only sites you trust.
Pros & cons
- Free to use and open source, with public code on GitHub
- Self-custodial design, so the project does not hold your funds
- Focused on Ethereum and EVM-compatible networks
- Supports Ledger hardware wallets
- Runs inside Chrome, Edge or Firefox without a separate desktop install
- The same project extends to macOS, Android, iOS, Docker and the web
- The Windows version is a browser extension, not a standalone desktop app
- Ethereum and EVM focus makes it a poor fit for non-EVM chains
- Self-custody means you alone are responsible for seed phrase backups
- Some features rely on third-party services with their own fees
- Browser extensions share the browser's attack surface, so fake copies are a real risk
Is Ambire safe?
Ambire is self-custodial, which means your security depends largely on your own habits. Download the software only from the official website or the GitHub Releases page, and never from links in messages or advertisements. Verify the SHA-256 checksum or signature before installing, and check the publisher details in your browser's extension listing.
Never enter your seed phrase on a third-party website, in a support chat or in a form that claims to restore your wallet. Legitimate software never needs it outside the wallet itself. Be cautious with look-alike extensions, since copies can ask for your seed phrase.
Where features use third-party providers, read their terms and fees before you connect. For larger balances, consider pairing the wallet with a hardware device.
- Official source only. Download from www.ambire.com. 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
Ambire occupies a different niche from several programs in this catalog. Frame is a desktop Web3 wallet that runs as a standalone program, while Ambire lives in your browser. MyCrypto also centers on Ethereum, but it focuses on managing Ethereum accounts rather than acting as an everyday extension.
Cake Wallet is a multi-currency, non-custodial wallet, so it suits people who hold many different coins. MyTonWallet is built specifically for TON, and Status Desktop combines a messenger, a wallet and a Web3 browser. If your priority is Ethereum and EVM networks through a browser, Ambire is the more direct fit.

Ambire can be used safely if you follow basic security habits. Download it only from the official website or GitHub, verify the SHA-256 checksum, and keep your seed phrase offline. Most losses come from phishing and fake copies, not from the wallet itself.
Yes. Ambire documents support for Ledger hardware wallets. Connecting a Ledger keeps your private keys on the device, and each transaction requires confirmation on the hardware screen, which adds a layer of protection.
The Windows version runs as a browser extension for Chrome, Edge and Firefox. You add it to your browser instead of installing a separate desktop program, and it appears in the toolbar once installed.
Ambire is built for Ethereum and EVM-compatible networks, and its documentation names Ethereum (ETH). Check the current documentation before sending funds on any network, since supported networks can change over time.
No. Ambire is self-custodial, so your keys and funds stay under your control. The project also does not act as a counterparty to trades, so there is no company holding your balance on its servers.

Verdict
Ambire suits Windows users who want a free, open-source, self-custodial wallet for Ethereum and EVM networks and who spend most of their time in a browser. It is a solid choice if public code and Ledger support matter to you. It is less suitable if you need a standalone desktop application or a wallet covering many non-EVM blockchains. Before installing, check the latest version on the official website, keep your seed phrase offline and test with small amounts first.
