Install the browser add-on exclusively from the official source to prevent fraudulent code. Verify the developer’s details match the legitimate entity before adding it to your browser. This initial step is the primary defense against losing your funds to malicious software.

During the creation of your new vault, the twelve-word secret recovery phrase is generated. Write these words on physical paper and store them offline. Digital screenshots or cloud storage create unacceptable vulnerabilities. This sequence of words is the absolute key to restoring your holdings on any compatible device; its security is non-negotiable.

Configure your preferred networks immediately after vault creation. The interface allows you to enable or disable specific blockchains like Solana, Ethereum, or Avalanche. Activating only the chains you frequently use streamlines the interface and reduces visual clutter, focusing attention on relevant balances and transactions.

For managing multiple accounts, utilize the built-in feature to create distinct portfolios. Assign one for daily transactions, another for long-term holdings, and perhaps a separate one for experimental assets. This practice provides clear organization and can enhance security by isolating funds based on their purpose.

Before confirming any transaction, double-check the recipient’s address and the selected blockchain. A common error is sending assets on a network the recipient does not support, which can result in permanent loss. Manually approving each connection request for decentralized applications limits exposure, revoking access for services you no longer use directly from the add-on’s permissions menu.

Downloading and Installing the Coin98 Browser Add-on

Navigate directly to the official Chrome Web Store or Firefox Add-ons portal. Search for the authentic utility; fraudulent copies exist. Verify the publisher is listed as “Coin98 Super Wallet” before proceeding with the installation.

Click ‘Add to Browser’ and confirm the permissions prompt. The icon will appear in your toolbar. Pin it for immediate access. A new tab will launch automatically–this is your vault’s interface. Do not close it. Immediately follow the on-screen prompts to either generate a fresh vault or restore an existing one using your secret recovery phrase. This step is mandatory for functionality.

Store your recovery phrase offline, on physical paper.

Never share this phrase or input it on any website.

Configure a strong, unique password for local transaction approvals.

After creation, fund your new address with a small test transaction to confirm everything operates correctly.

Creating and Securing Your First Digital Vault

Install the software from the project’s official website, never from third-party links or app store listings.

During generation, write the 12 or 24-word recovery phrase on paper, store this physical copy in a secure location like a fireproof safe, and never digitize it via photos, cloud notes, or text files.

Immediately after noting your seed phrase, confirm you can accurately restore access to a fresh, empty instance of the application; this practice verifies your backup’s correctness before funding the account.

Security Feature Action Required Priority

Transaction Signing Always verify the request details displayed before approving. High

Network Permissions Revoke unused dApp connections periodically from the settings menu. Medium

Phishing Attempts Ignore direct messages offering support or requesting your secret phrase. Critical

A strong, unique password exceeding 14 characters, combining case-sensitive letters, numbers, and symbols, protects local encrypted storage.

For significant holdings, consider a hardware-based key storage device; it keeps private keys completely offline, requiring physical confirmation for every transaction, thus nullifying remote attack vectors.

Regularly audit connected applications and transaction history.

Importing an Existing Wallet with a Recovery Phrase

Select “Import Wallet” from the main interface of the add-on.

You will be prompted for your twelve or twenty-four word secret phrase. Type it manually, in the correct sequence, with a single space between each term. Never paste this phrase into a text document or email. Accuracy is critical; a single misspelled word will prevent access.

Double-check for stray spaces at the start or end of the phrase.

Verify similar-sounding words (e.g., “write” vs. “right”).

Confirm the exact word count your original vault utilized.

After entering the mnemonic, establish a new, robust password. This password encrypts the local data store; losing it requires re-importing with the seed phrase again.

The software will then generate all associated addresses. This process is instantaneous. You should see your expected public keys and asset balances populate immediately if the mnemonic was correct.

Conduct a small test transaction before moving significant holdings. Send a minimal amount from this newly imported interface to another address you control, confirming both the send and receive functions operate correctly. This validates the entire restoration process.

Store your recovery phrase offline, separate from this device. The imported vault is only as secure as your seed phrase’s confidentiality. Treat those words with the highest level of permanent secrecy.

Adding and Managing Various Blockchain Networks

Navigate directly to the network management panel, often symbolized by a globe or list icon within the interface.

Select ‘Add Custom RPC’ to manually input new chain parameters. You will need precise data: Network Name, New RPC URL, Chain ID, Symbol, and Block Explorer URL. Inaccurate information here will cause failed transactions.

For Ethereum-compatible chains like Polygon or BNB Smart Chain, many parameters auto-populate after entering a correct RPC endpoint. Verify the Chain ID independently; a mismatch is a common error source.

Source RPC URLs from official project documentation, never from unofficial blogs or social media. A compromised RPC can lead to total fund loss. Consider adding multiple endpoints for the same network to maintain access during provider downtime.

Organize your active chains. Most interfaces allow you to reorder networks by dragging, prioritizing those you use daily. Disable or hide testnets or unused chains to streamline the selection menu and reduce visual clutter.

Regularly review and update your custom RPCs. Infrastructure providers occasionally deprecate old endpoints; an outdated URL will silently break your connection. Set a quarterly reminder to check each custom network’s status against official sources.

Delete networks you no longer interact with. This minimizes potential attack surface and keeps your list functional.

How to Send and Receive Cryptocurrency Assets

Always verify the network compatibility before any transaction; sending Ethereum-based USDT to a Solana USDT address guarantees permanent loss.

To receive funds, open your portfolio, select the desired asset, and click ‘Receive’. Share the generated public address or QR code with the sender. For enhanced privacy, generate a new address for each transaction–this feature is supported for Bitcoin and many Ethereum Virtual Machine chains. Double-check that the receiving network matches the sender’s outgoing network exactly.

Initiate a transfer by selecting ‘Send’ from the asset’s page.

Paste the destination address or scan a QR code. Manually typing addresses is strongly discouraged.

Select the network; confirm the recipient supports it.

Enter the amount. Review the dynamic transaction fee displayed.

Execute the transaction after verifying all details.

For significant amounts, conduct a test with a minimal sum first. Monitor the transaction status via the provided transaction hash on a block explorer like Etherscan or Solscan. Failed transactions still consume gas fees; adjusting the gas price can prioritize network confirmation during congestion.

Connecting the Wallet to Decentralized Applications (dApps)

Always verify the application’s URL before initiating a connection to avoid phishing attempts.

Your browser’s toolbar houses the utility; click its icon to see a list of compatible networks like Ethereum, BNB Chain, or Solana.

Select the precise network a dApp requires prior to linking; mismatches cause failed transactions.

Most platforms feature a prominent “Connect” button, typically triggering a modal window that displays available custodial interfaces–choose the correct one from this list.

A connection request pop-up from your interface will appear; scrutinize the permissions, then authorize it to establish the link.

Some complex DeFi platforms may need multiple authorizations for specific contracts; maintain this selective approach for each new request.

After a successful link, your public address and balance often display in a corner of the site, enabling immediate interaction with swaps, stakes, or NFT mints.

Terminate active sessions through the dApp’s interface or directly within your crypto tool’s “Connected Sites” settings menu to preserve security after concluding your activity.

Managing Token Visibility and Handling ‘Undetected’ Tokens

Immediately access the asset management panel within the interface to manually add any standard token contract address.

For tokens built on networks like Solana or BNB Smart Chain, this action forces a refresh of your balance sheet. Always verify the contract address on an official project source or a trusted block explorer before importing; entering a malicious address can lead to irreversible fund loss. This process does not require a transaction fee, as it merely modifies local display settings.

If a legitimate asset remains missing after manual import, confirm the network connection is correct. The application must be linked to the specific blockchain where the token was issued. Cross-chain assets, for instance, will not appear if you are viewing an incompatible chain. Persistent display issues may stem from the application’s internal token list not being updated, requiring a short wait for its metadata refresh or a manual cache clearance in your browser’s settings.

Q&A:

How do I install the Coin98 wallet browser extension?

First, visit the official Chrome Web Store or Firefox Add-ons site. Search for “Coin98 Wallet.” Select the legitimate extension published by Coin98 SuperApp. Click “Add to Chrome” or “Add to Firefox.” Confirm the installation when prompted. A new icon will appear in your browser’s toolbar. Click it to begin the setup process inside the extension.

I’m setting up a new wallet. What’s the safest way to handle my recovery phrase?

During setup, you will see a 12 or 24-word secret recovery phrase. Write each word down in the exact order on paper. Do not save it digitally—no screenshots, text files, or emails. Store the paper in a secure place, like a safe. Verify the phrase by correctly selecting the words when asked. This phrase is the only way to restore your wallet if you lose access; losing it means losing your funds permanently.

Can I use the extension with networks like Solana or Avalanche?

Yes. The wallet supports many networks. After setup, open the extension and find the network management section. You can add networks manually or select from a list. For Solana, it’s typically pre-installed. For others, you might need to input the correct RPC URL and Chain ID, which you can get from the network’s official documentation. Always double-check these details to avoid connecting to a malicious server.

What’s the difference between the main wallet and a sub-wallet within Coin98?

Think of your main wallet as your primary account, derived directly from your recovery phrase. Sub-wallets are additional accounts generated within the same wallet. They use the same recovery phrase but have unique receiving addresses. This lets you separate funds for different purposes—like one for trading and one for savings—without needing multiple seed phrases. You manage them all from a single extension login.

I sent tokens but the transaction is stuck. What can I do?

Check the transaction status on a block explorer using the transaction ID. If it’s pending, the network might be congested. Wait. If it fails, funds should return. You can sometimes speed up a transaction by sending a new transaction with a higher gas fee from the same wallet. In the extension, check the transaction history and ensure you have enough native currency (like ETH for Ethereum) to cover network fees for any new actions.

I installed the Coin98 extension but the interface feels overwhelming. Where should I focus first to just send/receive crypto safely?

After installing, focus on three areas. First, locate your wallet address. Click the extension icon, choose your wallet, and press “Receive.” This string of characters is your public address for receiving assets. Double-check it against the sender’s copy. Second, for sending, use the “Send” button. You’ll need the exact recipient address and the correct network (like Ethereum or BNB Chain). A wrong network means lost funds. Always send a tiny test transaction first. Third, secure your recovery phrase. If you haven’t already, write down the 12 or 24-word phrase on paper and store it offline. Never share it or type it into any website. Master these steps before exploring swaps or bridges.
