How to set up and use kaia wallet extension



Kaia wallet extension setup and usage guide

Download the official Klaytn-compatible browser tool exclusively from the Chrome Web Store or the Firefox Add-ons repository. Verify the developer is Kaia Chain Foundation and that the published date matches the latest release. Avoid third-party download sites to prevent malicious clones. After installation, pin the icon to your toolbar for direct access.


Open the application and select "Create a new vault". The interface will generate a 24-word recovery phrase. Write this phrase on paper using a pen–never store it digitally, in cloud services, or as a screenshot. Double-check each word for spelling errors. Confirm the phrase in the subsequent step to finalize the vault creation. This phrase is your sole method to restore access; losing it means permanent loss of funds.


Within the vault, generate a distinct account address. For token transactions on Kaia mainnet, ensure the network dropdown shows "Kaia Mainnet" (Chain ID: 8217) or tap "Add Network" to input the correct RPC endpoint: https://public-en.node.kaia.io. The tool supports KAIA coin transfers and ERC-20 compatible tokens natively. To receive assets, copy your public address from the account page; to send, click "Send", paste the recipient address, specify the amount, and confirm the gas fee (default values are acceptable for standard transfers).


For advanced functionality, access the "Settings" panel to enable test networks like "Kaia Kairos" for experimentation. Import tokens manually by pasting the contract address, symbol, and decimal count. Always verify token addresses against official sources like the Kaia portal. The built-in swap feature lets you exchange KAIA for other supported tokens directly, but confirm the slippage tolerance (e.g., 1%) before approving the transaction. Keep the extension updated manually by checking for new versions weekly, as security patches often coincide with network upgrades.

How to Set Up and Use Kaia Wallet Extension

First, download the official plugin directly from the Chrome Web Store or your browser’s add-on repository. Confirm the developer is "Kaia" before installing. Once added, pin the icon to your toolbar for quicker access. Click the icon, then select "Create a new wallet." You will be prompted to generate a 12-word mnemonic phrase–store this offline in a vault or on a steel plate, as it is the exclusive method to recover your accounts after a device wipe or browser reset.


Backup the recovery phrase: Write each word down sequentially. Never store this list on a cloud service, screenshot, or text file. Kaia’s client does not retain this data.
Confirm the phrase: The interface will ask you to rearrange the words correctly. Complete this verification to finalize creation.
Define a password: Choose a 12-character string with mixed cases, numbers, and symbols. This password encrypts the local data file on your machine and is required each session.


To receive tokens, open the extension and copy your public address (0x...). This identifier is safe to share for incoming transfers. To send tokens, click "Send," paste the recipient’s address, specify the amount, confirm the gas fee displayed in the transaction preview, and approve the action. For interacting with decentralized apps (dApps), navigate to the site, initiate a transaction, and a prompt from the plug-in will request your signature. Review the data, specifically the network ID and token amounts, under the "Data" tab before clicking confirm. Always verify the dApp URL matches the official domain to avoid phishing attempts.


Manage multiple accounts by clicking the account icon in the top-right corner of the popup and selecting "Create" or "Import" a private key. For custom network endpoints, go to Settings > Networks > Add Network. Input the RPC URL, chain ID (for Kaia mainnet: 8217; for Baobab testnet: 1001), and symbol "Kaia wallet recovery phrase." After adding, switch between networks using the dropdown at the top of the main screen. To disconnect from a dApp, return to the "Connected Sites" menu and revoke the connection. Clear transaction history by resetting the extension’s data through the browser’s extension management page, though this will require re-entering your mnemonic phrase.

Downloading the Official Kaia Wallet Extension from the Chrome Web Store

Open the Chrome Web Store and directly search for "Kaia Wallet" in the search bar. Verify you select the result published exactly by "Kaia Foundation" and check that the extension has over 100,000 active users and a rating of 4.5 stars or higher. Do not download any fork or duplicate listing; fraudulent copies often have fewer than 1,000 installs or misspelled developer names. Clicking "Add to Chrome" initiates a 2.3 MB download, which installs automatically under the puzzle icon in your toolbar.


After installation, pin the icon by clicking the puzzle piece in the upper-right corner of Chrome, finding "Kaia Wallet" in the dropdown, and clicking the pin symbol. Chrome may prompt you with a dialog box requesting permission to "Read and change your data on websites you visit." This permission is mandatory for the application to inject transaction sign-in prompts and read-chain interaction requests from dApps like KLAYswap or Kaia Square. Accepting this prompt finalizes the installation process without any further configuration needed at this stage.


Before any transaction, confirm the extension’s version number matches the repository on GitHub under kaiachain. Version 1.4.1 (released March 2025) requires Chrome 110 or higher. Check this by right-clicking the pinned icon, selecting "Manage extensions," and toggling "Developer mode." The version appears under the extension name. If your version is older than 1.3.9, the application will fail to connect to Kaia mainnet nodes due to API deprecation. Redownload through the store to force an update.

Do not use alternative browsers or mobile Chrome for this download–the desktop Chrome browser on Windows 10+, macOS 11+, or Linux x86_64 is the only supported environment as of March 2025. A common installation failure occurs when your Chrome profile has disabled third-party extension installation via group policy (visible at chrome://policy). Resolve this by running Chrome as administrator or clearing the "ExtensionInstallBlocklist" policy for your user profile. Once installed and pinned, the icon immediately displays a "Get Started" screen requiring no data from the store–only cryptographic key generation occurs here.

Creating a New Wallet: Generating Your Seed Phrase and Setting a Strong Password

Open the application and select the option to create a fresh account. You will be presented with a sequence of 12 or 24 words–this is your seed phrase, the single master key to all your assets. Never type it on a computer or take a screenshot; write it down on paper with a pen.


Store this document inside a fireproof safe or a bank deposit box. A single typo or loss renders your funds irrecoverable, as no support team can reverse a blockchain transaction. Verify your backup by re-entering the words in the exact order the system presents them.


Following seed confirmation, define a password for local device access. This password encrypts the application data on your machine. Generate a string of at least 16 characters, mixing uppercase, lowercase, numbers, and symbols like `%$#@!`. Biometric authentication, such as a fingerprint, can be activated as a secondary convenience after the password is established.


Avoid phrases from literature, song lyrics, or common substitutions (e.g., "p@ssw0rd"). Instead, employ a random generator tool or construct a sentence with obscure references, then modify its letters. For instance, "My blue bike cost 94 dollars!" becomes `MbBc94$!`.


The password protects against local intruders who gain physical or remote access to your computer. Without it, the encrypted wallet file is gibberish. Change this password every 90 days and never reuse it across other platforms.


Write your seed phrase on a single sheet, not multiple scraps. Consider a secondary backup etched into a cryptosteel capsule, which resists fire and flood. Do not store digital copies in cloud drives, notes apps, or emails.


Perform a test by closing the application entirely, then restoring your identity from the written seed words alone. Confirm that all balances and transaction history re-appear identically. This validates your backup before you deposit any significant value.


Schedule a quarterly audit of the physical seed sheet for fading ink or damage. Replace the paper if it shows wear. These mechanical steps form the stark foundation of your self-custody. Neglect them, and technical sophistication offers zero protection.

Importing an Existing Wallet Using a Private Key or Recovery Phrase

Open the application and immediately select the "Import wallet" option from the initial screen. You must choose between two distinct authentication methods: a 12 or 24-word mnemonic seed phrase or a single private key string. For the recovery phrase, ensure you enter all words in the correct order with lowercase letters and single spaces between each term; a single typo will generate an error. Private keys must be copied exactly as shown, typically starting with "0x" for those generated on EVM-compatible chains.


When pasting a mnemonic phrase from a clipboard, manually verify each word against your original paper backup. Digital copies are vulnerable to malware and keyloggers–type the phrase manually whenever possible. The interface will display a word count indicator; confirm it matches your source (12 or 24). If your original wallet derived addresses using a specific BIP-39 passphrase, you will need to append that passphrase after the seed words in the designated field.


After submission, the application performs a local derivation of all associated addresses without transmitting your credentials to any remote server. You will see a list of accounts that match the imported seed or key. Select the specific address containing your assets; multiple addresses may appear if your original wallet used hierarchical deterministic (HD) derivation paths. Use a test transaction or check known token balances to confirm you have selected the correct account.


For imported private keys, note that these single-key imports do not support HD derivation–you obtain exactly one address. To manage multiple addresses from a single seed, repeat the full import process using the recovery phrase method instead of the private key option. The application stores the imported key locally in an encrypted vault, protected by a new password you define during the setup.


Test the imported account by sending a minimal amount (e.g., 0.001 unit of the native token) to a different address you control. Verify the transaction appears in the history and the balance updates correctly. If the derivation path from your original wallet was non-standard (e.g., Ledger Live vs. Metamask), click the "Advanced" option during import to specify the exact BIP-44 path, such as `m/44'/60'/0'/0/0`.


Immediately after successful verification, delete any digital screenshots or text files containing your private key or recovery phrase. Write the new password for this application on a separate physical document; losing it locks access even with the original seed. Do not reuse the same password across multiple financial tools.

Q&A:
I installed the Kaia Wallet extension, but I see "Create Wallet" and "Import Wallet." If I pick "Create Wallet," do I get to choose my own password right away, or does it show me the seed phrase first?

When you click "Create Wallet," the first thing you see is a screen asking you to set a strong password. You need to enter it twice and confirm it. Only after that does the extension generate your 12-word recovery seed phrase. You will be asked to verify the phrase by selecting the words in the correct order before the wallet becomes active. The password is what you use to unlock the extension every day, while the seed phrase is your absolute backup.

What exactly is "Kaia" in the wallet? Is it just the name of the extension, or does it refer to a specific blockchain network I need to add manually?

"Kaia" is both the name of the extension and the name of the native blockchain network it is built for. Kaia is a layer-1 blockchain (a merger of the Klaytn and Finschia chains). The wallet extension comes pre-configured to connect to the Kaia Mainnet and the Kaia Kairos Testnet. You do not need to add the Kaia network manually—it is already there. The extension does support other EVM-compatible networks (like Ethereum or BNB Smart Chain), but you would have to add those through the settings menu under "Networks."

I read that the Kaia wallet has a "Social Recovery" feature. How does that work in practice? Does it mean I don't need to save my seed phrase?

Social Recovery is an optional feature available for Kaia-specific accounts. It is not a replacement for your seed phrase—you still need to save that when you first create the wallet. What Social Recovery does is let you set up a list of "Guardians" (other trusted wallets). If you lose access to your device or forget your password, you can use a majority of these Guardians to reset your access to that specific wallet address. This is a safety net for regaining access to your account without exposing your private key, but your original seed phrase remains the most direct form of recovery.

I’m trying to send KAIA tokens to a friend, but the transaction keeps failing with a "low gas price" error. How do I fix this without just guessing a number?

This error usually means the network base fee has changed since you tried to send the transaction. Open the Kaia wallet extension and start the transfer as normal. On the confirmation screen, look for a small "gear" icon or a "Gas Settings" toggle. Tap that. You will see two numbers: "Max Priority Fee" and "Max Fee." The extension usually has a "Suggested" option (like Low, Medium, High) or a "Market" setting. Click on "Medium" or "High" to add a small tip to the validator. You can also use a block explorer like Kaiascope (kaiascope.io) to check the current gas price before sending. The wallet does not adjust gas automatically for past failed transactions, so you must re-initiate the transfer with the corrected fee.
