Ninji Wallet documentation: your Injective wallet guide

Ninji Wallet is a self-custody desktop wallet for the Injective ecosystem. It runs as a native application on Windows, macOS and Linux, so your keys are generated and stored on your own computer — never on our servers.

This documentation walks you through installing the app on each platform, creating or importing a wallet, protecting your recovery phrase and using everyday features like sending, receiving and staking INJ.

Self-custody means you alone control your funds. Before installing, keep these rules in mind:

1. 1Your 12-word recovery phrase is the only way to restore your wallet. Write it on paper and store it offline.
2. 2Ninji will never ask for your recovery phrase by email, chat or support ticket.
3. 3Only download Ninji Wallet from the official website. Verify the file before installing.
4. 4Use a strong, unique password to unlock the app on your device.

Ninji Wallet for Windows is distributed as a standard .exe installer.

System requirements

Install

1. 1Download the Windows installer (.exe) from the Download section of the official website.
2. 2Open the downloaded file. If Windows SmartScreen appears, confirm the publisher is Ninji before choosing Run.
3. 3Follow the setup wizard and choose an installation folder.
4. 4Launch Ninji Wallet from the Start menu or the desktop shortcut.

Update & uninstall

The app notifies you when a new version is available. To uninstall, open Settings → Apps → Installed apps, select Ninji Wallet and choose Uninstall. Make sure your recovery phrase is backed up first.

Ninji Wallet runs natively on modern Macs, including Apple silicon and Intel models.

System requirements

Install

1. 1Download the macOS build from the Download section of the official website.
2. 2Open the downloaded file and drag Ninji Wallet into your Applications folder.
3. 3Launch the app from Applications or Launchpad.
4. 4If macOS asks for confirmation on first launch, check that the developer is Ninji and choose Open.

Uninstall

Quit the app, then drag Ninji Wallet from Applications to the Trash. Back up your recovery phrase before removing the app.

Ninji Wallet supports popular 64-bit Linux distributions.

System requirements

Install

1. 1Download the Linux build from the Download section of the official website.
2. 2Open a terminal in the download folder.
3. 3Make the file executable if needed, then start the application.

chmod +x ./ninji-wallet*
./ninji-wallet*

1. 1Open Ninji Wallet and choose Create Wallet.
2. 2Set a strong password. It unlocks the app on this computer only.
3. 3Write down the 12 secret words in the exact order shown.
4. 4Confirm the words to prove your backup is correct.
5. 5Your Injective address is ready to receive assets.

Already have an Injective wallet? Choose Import Wallet, enter your recovery phrase and set a new local password. Your balances and assets appear once the app syncs with the network.

Receive

Open Receive to display your Injective address and QR code. Share only this address.

Send

1. 1Choose Send and select the token.
2. 2Paste the recipient address and enter an amount.
3. 3Review the network fee and confirm the transaction.

Staking lets you delegate INJ to a validator that helps secure the Injective network. In return you earn a share of network rewards, while your tokens remain under your own control.

Delegate

1. 1Open Staking and browse the list of active validators.
2. 2Compare commission, voting power and uptime before choosing.
3. 3Enter the amount of INJ to delegate and review the fee.
4. 4Confirm with your password. Rewards begin accruing after the next block.

Claim, redelegate & undelegate

Claim accumulated rewards at any time. You can move your stake to another validator without waiting, or undelegate to make tokens transferable again after the Injective unbonding period ends.

The Assets view lists INJ and every Injective token held by your address, with balances refreshed automatically. Hidden or small balances can be toggled from the list settings.

Add a custom token

1. 1Open Assets and choose Add token.
2. 2Paste the token's denom or contract address.
3. 3Confirm the symbol and decimals, then save.

NFT gallery

Injective NFTs appear in a dedicated gallery. Open any item to see its collection, attributes and transfer it to another address.

Ninji Wallet can approve connections and signing requests from Injective applications. Every request opens a review window inside the desktop app showing the site, the action requested and the estimated fee.

1. 1Choose Ninji Wallet when an Injective dApp asks you to connect.
2. 2Review the permissions requested and approve or reject.
3. 3Manage or revoke connected sites anytime in Settings → Connected apps.

Create several accounts from one recovery phrase or import independent wallets, then switch between them from the account menu. Rename accounts and assign colours to keep personal, trading and long-term holdings separate.

Your recovery phrase restores your wallet on any computer running Ninji Wallet. Treat it like the keys to a vault.

Restore on a new computer

1. 1Install Ninji Wallet for your platform.
2. 2Choose Import Wallet and enter your 12 words in order.
3. 3Set a new local password. Your accounts reappear automatically.

Always confirm that the installer you downloaded is authentic before running it. Each release will publish a SHA-256 checksum next to its download.

Windows (PowerShell)

Get-FileHash .\ninji-wallet-setup.exe -Algorithm SHA256

macOS & Linux (Terminal)

shasum -a 256 ./ninji-wallet*

Compare the result with the checksum on the official website. If they differ, delete the file and do not install it.

1. 1Keep your operating system and Ninji Wallet up to date.
2. 2Enable auto-lock so the app locks after a period of inactivity.
3. 3Use a reputable antivirus and avoid installing unknown software.
4. 4Bookmark the official website to avoid phishing copies.
5. 5Start with a small test transaction when sending to a new address.

Ninji Wallet is non-custodial. Private keys and recovery phrases are encrypted locally with your password and never leave your device. The app connects to Injective network nodes to read balances and broadcast transactions you approve.
