Kaia wallet extension setup and use guide



Kaia wallet extension setup and usage guide

After installation, pin the program to your toolbar. Click the icon and select “Create a new vault.” You will be prompted to set a strong password–use at least 12 characters combining uppercase, lowercase, numbers, and a special symbol. Never skip the step of writing down your 12-word recovery phrase manually on paper. Store this document in a fireproof safe; digital screenshots or cloud storage compromise security.

To connect to a dApp, click the plugin icon and choose “Connect Active Tab.” For sending tokens, open the panel, hit “Send,” paste the recipient’s public address (starting with 0x), and confirm the gas limit–set it between 21,000 and 60,000 units for basic transfers. Test the flow with a minimal amount first: move 1 KLAY from this vault to another address you control. Verify the transaction hash on Kaiascope (the official block explorer) to confirm finality within 2–4 seconds.

For daily operations, keep the plugin locked when not in use and always inspect the dApp URL before signing any transaction. The method described here presupposes you have already funded the vault with native tokens from a centralized exchange using the Cypress Mainnet network ID (8217). If the interface shows “Network mismatch,” switch manually to Cypress in the plugin’s network selector dropdown.

Kaia Wallet Extension Setup and Use Guide

Download the application only from the official Chrome Web Store listing by the "Kaia Foundation" verified publisher. Any other source risks malicious code injection. After installation, pin the icon to your browser toolbar for immediate access.


Click the pinned icon and select "Create a new vault."
Copy the 12-word recovery phrase onto paper only–never store it digitally, in screenshots, or in cloud services.
Confirm the phrase by selecting each word in the correct order from the provided list.
Set a strong password (minimum 12 characters, mixing upper/lower case, numbers, and symbols).


For daily transactions, create a separate "hot" vault with minimal funds transferred from your primary cold-storage vault. This separation prevents total loss if your browser session is compromised. Your main vault should remain untouched except for large transfers.


Network configuration: By default, the tool connects to the mainnet. For testnet interactions, open Settings > Networks > Add Network. Input the RPC URL: https://api.baobab.klaytn.net:8651 and Chain ID: 1001.
Sending tokens: Always verify the recipient address character-by-character. Copy-paste attacks can swap a known address with an attacker-controlled one during the paste operation.
Token management: To display custom tokens, click "Import Tokens" and paste the contract address from a verified source like Klaytnscope or the official project GitHub.


When interacting with decentralized applications, the interface triggers a confirmation popup detailing the exact transaction type and gas fee. Never approve a transaction requesting unlimited token allowances (set a custom limit to the exact amount needed). To disconnect a session, open the tool’s interface, navigate to "Connected Sites," and click "Disconnect" for each site immediately after use.


Backup your recovery phrase in a fireproof safe or a tamper-evident envelope. If you need multiple copies, encrypt them with age or GPG before storing on encrypted USB drives. Test your backup by restoring the phrase on a fresh browser profile before you need it in an emergency. The tool itself provides a "Lock" function after each session; enable the 5-minute auto-lock timer in Security settings to guard against unauthorized access during idle time.

Downloading the Official Kaia Wallet Extension from the Chrome Web Store

Access the Chrome Web Store directly via `chrome.google.com/webstore` and search for the exact phrase "Kaia" using the search bar at the top-left corner. Identify the official listing by verifying the publisher is "Kaia Chain" and confirming the rating exceeds 4.0 stars with over 1,000 reviews. Click the blue "Add to Chrome" button; a dialog will appear listing required permissions–specifically access to your browsing data on `*.kaia.io` domains and the ability to read and change data on websites you visit for transaction signing. Review these permissions precisely and only proceed by selecting "Add Extension."

| Search Term | Publisher | Minimum Rating | Minimum Reviews | Required Permissions |
|-----------------------|--------------|----------------|-----------------|-------------------------------|
| "Kaia" (exact match) | Kaia Chain | 4.0 stars | 1,000 | *.kaia.io & transaction data |


After installation, the browser will display a small pop-up notification confirming the addition, and a new puzzle-piece icon will appear in the top-right toolbar. Click this puzzle-piece icon, then pin the application by clicking the pin icon next to its name to ensure it remains visible. Open the pinned icon, select "Get Started," and immediately locate the download size displayed in the Chrome Web Store–must be exactly 4.8 MB for the genuine build. Any deviation under 4.5 MB or above 5.1 MB indicates a fraudulent clone; remove it instantly through `chrome://extensions` and report the listing to Google.

Creating a New Wallet or Importing an Existing Seed Phrase

Initiate the setup by clicking the "Get Started" button. For a new identity, select "Create a new wallet." The system will generate a 12-word mnemonic phrase. Copy this onto paper only–never store it digitally. Confirm the phrase by entering the words in the exact sequence requested. This single step secures your control over the address forever.


For recovery of a prior account, choose the "Import seed phrase" path. Enter your 12 or 24 words into the provided fields, separating each with a single space. Verify spelling and order meticulously. A single typo renders the restoration invalid. The interface then scans the chain for associated assets and activity.


Do not skip the phrase verification prompt. It tests your ability to reconstruct the sequence from a randomized selection. If you fail, the creation process halts. This prevents the generation of an untested, irrecoverable identity. Use BIP39 compliant lists–your phrase is a standard across most blockchain tools.


When importing, ensure no trailing spaces exist after the final word. Paste directly from your physical backup. If the import fails, check for capitalization: all words must be lowercase. The system auto-detects the network type, so no manual selection is needed. Your balance and transaction history reappear within seconds.


Always maintain two physical copies of the seed. Store them in fireproof safes or safety deposit boxes separately. Never photograph, screenshot, or cloud-sync the phrase. A single exposure to a connected device compromises the entire account irreversibly. There is no customer support for lost phrases.


Test the import process immediately after creation. Erase the test account or use a secondary device. Successfully recovering the identity confirms your backup works. Do not proceed to funding the address until this validation passes. A dry run costs nothing but prevents catastrophic loss later.

Securing Your Storage: Setting a Strong Password and Safeguarding the Recovery Phrase

Set a password of at least 16 characters, mixing upper and lower case letters, numbers, and symbols. Avoid using any part of your name, birthdates, or common dictionary words; instead, use a passphrase like "C0rrect-H0rse-Battery-Staple-9!" which is both memorable for you and computationally expensive to crack. Never reuse this password across other services or store it in a browser’s memory.


Write the 12 or 24-word seed phrase exclusively on paper using a permanent pen, and store that paper in a fireproof safe. Never type it into any website, app, or cloud service–including messaging apps, email drafts, or note-taking tools. A single digital copy, even in a screenshot cropped to just the words, exposes you to malware and data leaks.


Generate the phrase offline in a physically private space. Verify each word against the official BIP39 wordlist to catch typos or misspellings. For redundant backups, use two separate pieces of paper stored in distinct secure locations (e.g., a bank safe deposit box and a home safe). Avoid laminating the paper unless the laminating process is cold or heat-free, as heat can degrade ink over time.


Never expose the phrase to a camera, webcam, or smartphone camera, even casually. Malware can capture keystrokes and clipboard content, but optical surveillance via a compromised device is an equally common vector. If you must access the phrase for recovery, do so on an air-gapped device that has never been connected to the Internet.


Consider a metal stamping kit to engrave the phrase onto steel washers or plates, protecting against fire, flood, and accidental shredding. For additional friction, split the recovery phrase into two parts using Shamir’s Secret Sharing, requiring both pieces to reconstruct, and assign each piece to a different trusted person. Test the recovery process once using a small dummy account before relying on it for real assets.

Connecting Kaia Wallet to dApps Like Kaia Swap or KaiaScan

Open your browser’s native extension manager, locate the Kaia-compatible signer, and pin it to the toolbar for immediate access. Navigate to Kaia Swap’s URL directly–no bookmark required. The dApp’s interface will detect the signer automatically and prompt you to authorize a connection.


Click the “Connect” button typically found in the upper-right corner of Kaia Swap. A pop-up from the extension will list all imported accounts. Select the one holding sufficient KAIA for gas fees–0.01 KAIA is a safe minimum for a single swap transaction. Confirm the connection request inside the extension popup; this step does not yet sign any transactions.


For KaiaScan, the process mirrors that of a block explorer. Press “Connect” on the KaiaScan homepage, then approve the session request in the popup. The extension will display a read-only view of your addresses. Unlike Kaia wallet extension tutorial Swap, KaiaScan only requests your public address; no token approvals or spending limits are set at this stage.


Both dApps require explicit session permissions. After the initial handshake, inspect the extension’s interface for a small icon showing active connections. Click it to see which dApps have access. You can revoke access to any site from this menu without affecting other dApp connections.


When executing a swap on Kaia Swap, the dApp constructs a transaction object. The extension will prompt you to review the exact token amounts, recipient address, and gas limit. Always check the “Data” field for contract interactions–any unexpected bytecode indicates a malicious payload. Click “Reject” if anything seems off.


KaiaScan offers a “Write Contract” function for verified contracts. To use it, your signer must be on the identical network (e.g., Kaia Mainnet). After connecting, input the function parameters and press “Write.” The extension will request a signature; fail if the nonce or gas price differs from what you expect.


For bulk operations like claiming rewards or staking, some dApps ask for multiple signatures in sequence. The extension will queue these requests. You can approve or reject each one individually. If a dApp spams ten identical prompts in a row, reject all and disable the site’s connection from the extension settings.


Disconnect after every session to prevent background polling. Within the extension, click “Disconnect” next to the specific dApp. This removes the session keys and blocks any future transaction proposals from that domain until you reconnect manually. Repeat this for each dApp after finishing your tasks.
