FAQ

With KEYRING PRO, you can manage all of your accounts easily.

Is manual private key generation safe?

Yes, it is safe. The private key will be stored on the device where it was created.

The private key is encrypted using AES-256 and the password set by the user. It is then stored in the secure storage of the device.

AES-256 stands for Advanced Encryption Standard with a 256-bit key. It is a widely used encryption standard for protecting sensitive data.

How many accounts can I create?

You can manage up to 20 accounts in total.

This includes all types of accounts, such as:

• Created accounts

• Imported accounts

• Restored accounts

• Registered 0x addresses

• Other account types

How many networks or chains does KEYRING PRO support?

KEYRING PRO Wallet currently supports EVM-compatible chains, which means chains that are compatible with the Ethereum Virtual Machine.

In addition to the default chains, you can add other EVM-compatible chains manually.

For more details, please refer to the Network section.

What happens to my Bitcoin or Solana wallet from the old KEYRING PRO version?

KEYRING PRO Wallet now only supports EVM-compatible chains. This means you can no longer create new wallets for non-EVM chains such as Bitcoin or Solana.

For Bitcoin or Solana wallets created in older versions of KEYRING PRO Wallet, the wallet addresses will still be displayed. However, you can only view their private keys. You will not be able to perform other actions like you can with EVM tokens.

What is Register 0x Address?

Register 0x Address is also known as a View Only Account. This means the account can only be viewed and cannot be used to perform actions.

In simple terms, it allows you to view the portfolio of a wallet address without controlling that wallet.

For example, you can add the wallet address of a whale or trader you follow and monitor what they buy or sell.

Some of my tokens do not show in the app. What should I do?

There are usually three possible reasons:

1. The token has a very small total value, or it has very few users or transactions.

2. The token is not officially listed yet, and data platforms such as CoinGecko or CoinMarketCap may not display it.

3. The token belongs to a non-EVM chain.

For cases 1 and 2, you can add the token manually.

Please see the guide here:

[link]

For case 3, the app will not display or support the token.

Where are backup files saved?

When you create a backup file, you can choose where to save it. For example, you can save it directly on your device or to cloud storage.

However, when restoring from a backup file, you must be able to select and open that file. This means the backup file needs to be available on your device when you restore it.

If you originally saved the backup file on your device, the system will open the folder path where you last saved a backup file.

What happens if I forget the password of a backup file?

If you forget the password of a backup file, you will not be able to restore that backup file.

KEYRING PRO Wallet cannot help you recover it because it is a non-custodial wallet. We cannot access the data stored on your device.

Even if you delete and reinstall the app, you will still need the correct password to restore that backup file. Each backup file is encrypted with the password set for that specific file, so you must enter the correct password for that file.

What happens if I forget my wallet password?

Your wallet password is an important part of the wallet security process. It is used to encrypt your private key when creating a wallet and to verify important actions when using the wallet.

It works as one of the main security layers for your wallet.

If you lose your wallet password, KEYRING PRO Wallet cannot help recover it because it is non-custodial. We do not collect or store user wallet data.

One possible way to recover your wallet is to delete and reinstall the app, then import the wallet again using its private key.

Why can I not copy my private key?

For security reasons, KEYRING PRO Wallet no longer allows users to copy private keys directly in the app.

When something is copied, it is stored in the device clipboard. In most cases, this is safe, but there is still a risk that another app or malicious software could read the clipboard and expose the private key.

To reduce this risk, KEYRING PRO Wallet does not allow private keys to be copied directly from the app.

However, you are still free to copy a private key from outside the app and paste it into KEYRING PRO Wallet if you choose to do so.

How do I close a page and go back?

To close a page, swipe down from the top edge of the pop-up window.

Why can I not use WalletConnect Pay?

To use WalletConnect Pay, make sure the store supports payments through WalletConnect Pay.

You also need to make sure you have the correct token required for the payment.

Can I add testnet networks or tokens?

Yes, you can.

KEYRING PRO Wallet allows you to add any network or token, including testnet networks and tokens, as long as they are EVM-compatible.

Can I hide the Link and TXD ub the My Liquidity page?

Yes, just swipe to the left.

Can I customize the Auto-Lock time?

Yes and no.

You can change the Auto-Lock time in the Security settings, but you can only choose from the available time options. You cannot set a custom time freely.

Available options include:

• 10 minutes

• 30 minutes

• 1 hour

• 12 hours

• 24 hours

• Never

Why do I see a notification bell on the Home screen?

The bell means there is a new announcement from the KEYRING PRO team, such as app updates, maintenance, or important notices.

These are not transaction, swap, or wallet activity notifications.

Tap the bell to read the announcement. The badge will disappear after you read all of them.

Why can I use a 4-digit passcode when the new password requires 8 characters?

The 4-digit passcode option is only available for existing users who had already set a passcode in the old version of KEYRING PRO.

If you are an existing user, you may choose to reuse your old passcode as your new password. However, for better security, we recommend setting a new password with at least 8 characters.

New users must create a password with 8 characters.

Can I hide tokens?

Yes

1. Swipe left on the token you want to hide

2. Tab the hide icon.

Can I unhide tokens?

Yes

1. On the token page, tap obn the hide icon in the bottom left

2. It will shot a list of hidden tokens.

3. Tap con the token you want to reveal

4. tap on the Show button.

5. It'll be back in your shown token list.

How do I know which accounts that I have exported to an NFC card?

There will be an icon shown under the account:

• Fire icon: hot wallet

• Ice icon: cold wallet - meaning this account has been exported to an NFC card.

• Eye icon: This is a view-only account

Why can’t I use the NFC function?

There are several reasons why the NFC function may not work:

• NFC is not enabled on your phone.

• The NFC card already contains another account.

• Your phone does not support NFC.

• Your phone case is too thick or contains metal that interferes with NFC scanning.

• The NFC card was removed before the scanning process was completed.

• And more

Carefully check for any factors that may interfere with the NFC function before trying again.

How do I import an account from an NFC card into KEYRING PRO Wallet?

You cannot import an account directly into KEYRING PRO Wallet simply by scanning the NFC card.

KEYRING PRO Wallet does not support importing a wallet directly from an NFC card.

To import the account:

1. Use the Show Private Key function.

2. Retrieve the private key stored on the NFC card.

3. Use the private key to import the account into KEYRING PRO Wallet.

How do I export an account to an NFC card?

You can export an account to an NFC card using the Advanced Protection for Pro Users feature.

For detailed instructions, see Advanced Protection for Pro Users under NFC Tag Operation.

What NFC cards work with KEYRING PRO?

KEYRING PRO should work with most compatible NFC cards. However, the most compatible supported tag types are NTAG215 and NTAG216.

Why do I have more than 20 accounts?

If you updated from an older version of KEYRING PRO Wallet, all accounts created in the previous version will continue to be displayed, even if the total number exceeds 20.

However:

• Bitcoin and Solana accounts will only support the View Private Key function. This allows you to retrieve the private key and import the account into another compatible wallet. KEYRING PRO Wallet only supports Ethereum and EVM-compatible networks.

• EVM accounts will continue to work normally even when the total number of accounts exceeds the limit.

• You cannot create or import additional accounts once the total number of accounts reaches 20 or more.

What is included in a KEYRING PRO backup file?

A KEYRING PRO backup file saves the complete wallet state at the time the backup is created.

This includes:

• All accounts in the wallet

• Imported accounts

• Registered view-only addresses

• Added networks

• Added tokens

• Custom networks and tokens

• Testnet networks and tokens

When the file is restored, KEYRING PRO restores the wallet exactly as it was when the backup file was created.

Does a backup file update automatically?

No.

A backup file only contains the wallet data that existed when the file was created. Accounts, networks, or tokens added afterward will not be included.

Create a new backup file whenever you make important changes to your wallet.

Can I restore my KEYRING PRO Wallet on another device?

Yes.

Install KEYRING PRO Wallet on the other device, select Restore Using Backup File, choose the correct backup file, and enter the password set for that file.

A KEYRING PRO backup file can only be restored using KEYRING PRO Wallet.

Can I restore a KEYRING PRO backup file in another wallet app?

No.

KEYRING PRO backup files can only be restored in KEYRING PRO Wallet. Other wallet apps cannot read or restore the backup file directly.

To access the same account in another compatible wallet, you must import the account’s private key individually.

What happens when I restore a backup file?

Restoring a backup file replaces the entire wallet currently stored in KEYRING PRO.

The current wallet and the wallet saved in the backup file are not merged. After restoration, KEYRING PRO will contain only the accounts, networks, and tokens saved in the selected backup file.

Before restoring, make sure you have safely backed up the wallet currently stored on the device.

What happens if I restore an old backup file?

KEYRING PRO will return to the wallet state saved in that old backup file.

Accounts, networks, and tokens added after the old backup was created will no longer appear in the app after restoration.

This does not delete assets from the blockchain. However, you may lose access to accounts that were not included in the restored backup unless you have their private keys or a newer backup file.

Can I merge a backup file with my current wallet?

No.

Restore Using Backup File replaces the current wallet. It does not add or merge the contents of the backup file with the wallet currently stored in KEYRING PRO.

Can I use the same backup file more than once?

Yes.

You can use the same backup file to restore your wallet in KEYRING PRO more than once, including on another device.

You must select the correct backup file and enter the password assigned to that file.

Is my KEYRING PRO password the same as my backup file password?

No.

Your KEYRING PRO password is used to access and protect the wallet application.

A backup file password is created specifically for an individual backup file. Each backup file can have a different password.

Does changing my KEYRING PRO password change my backup file password?

No.

Changing your KEYRING PRO password does not change the passwords assigned to backup files that were previously created.

You must continue using the original password set for each backup file.

Can I restore an old backup file after changing my KEYRING PRO password?

Yes.

To restore the backup file, enter the password originally set for that specific file. Your current KEYRING PRO password is not used to unlock an existing backup file.

Is my backup file automatically stored by KEYRING PRO?

No.

KEYRING PRO does not keep, upload, or synchronize a copy of your backup file.

You must choose where to save the file and keep both the file and its password safe.

What should I do before uninstalling KEYRING PRO or changing my device?

Before uninstalling KEYRING PRO, resetting your device, or moving to another device:

1. Create a new backup file.

2. Store the backup file in a safe location.

3. Make sure you remember the password set for that backup file.

4. Keep the private keys of important accounts in a secure location.

To restore using the backup file on another device, you must install KEYRING PRO Wallet. To access the accounts through another wallet app, you must import each private key separately.

What should I do if I forget my KEYRING PRO password?

KEYRING cannot view, reset, or recover your KEYRING PRO password.

You will need to reset the wallet on the device and restore access using one of the following methods:

• Restore the wallet in KEYRING PRO using a backup file and the correct backup-file password.

• Import each account again using its private key.

If you do not have a backup file, its password, or the account private keys, the wallet cannot be recovered.

Does deleting an account from KEYRING PRO delete my assets?

No.

Your assets are stored on the blockchain, not inside KEYRING PRO. Deleting an account only removes access to that account from the current wallet on the device.

To access the account again, you must import its private key or restore a backup file that contains the account.

Why can’t I send tokens from a registered 0x address?

An account added using Register 0x Address is a view-only account.

KEYRING PRO does not have the private key for that address, so the account can only be used to view balances and transaction information. It cannot send tokens or confirm transactions.

Can I receive a token that has not been added to my token list?

Yes.

Tokens can be sent to your wallet address even if they have not been added to your token list.

The tokens still exist on the blockchain. Adding the token to KEYRING PRO only allows its balance and information to be displayed in the app.

Why does my account have the same address on different networks?

Ethereum and EVM-compatible networks use the same address format.

The same private key normally generates the same 0x address across supported EVM networks. However, each network has its own balances, tokens, and transaction history.

Having an asset on one network does not mean that the same asset is available on another network.

Why does KEYRING PRO show “Insufficient Gas Fee” even though I have enough tokens?

The token being sent and the token required to pay the gas fee may be different.

For example, having enough USDT on Ethereum does not cover the gas fee. You still need ETH on the Ethereum network to process the transaction.

Make sure the account has enough of the network’s native token to pay the gas fee.

Why did my transaction fail but still use a gas fee?

Gas fees are paid to the blockchain network for processing a transaction.

A transaction may fail after the network has already performed part of the required processing. The gas used during that process is normally not refunded.

Why is my transaction still pending?

A transaction may remain pending because:

• The network is congested.

• The gas fee is too low.

• The RPC connection is responding slowly.

• An earlier transaction from the same account is still pending.

Do not repeatedly submit the same transaction without checking its current status first.

Can KEYRING PRO cancel or reverse a completed transaction?

No.

Once a transaction has been confirmed on the blockchain, KEYRING PRO cannot cancel, reverse, or recover it.

Always check the wallet address, network, token, and amount carefully before confirming a transaction.

Can KEYRING recover tokens sent to the wrong address or network?

No.

KEYRING cannot control the blockchain or the recipient’s wallet and cannot reverse a confirmed transaction.

If the tokens were sent to your own address on a different EVM network, they may still be accessible by opening the correct network. However, tokens sent to an incorrect address may be permanently inaccessible.

WalletConnect and Website Security

Is connecting my wallet the same as approving a transaction?

No.

Connecting a wallet normally allows a website to view public information such as your wallet address.

Sending tokens, approving tokens, or interacting with a smart contract requires a separate request that you must review and confirm.

Can a website access my private key through WalletConnect?

No.

Your private key is not shared with the connected website through WalletConnect.

However, a malicious website may send unsafe transaction or approval requests. Always review every request carefully before confirming it.

What should I check before approving a WalletConnect request?

Before confirming a request, check:

• The website URL

• The selected network

• The token and amount

• The recipient or smart contract address

• The action being requested

• Any safety warning displayed by KEYRING PRO

Do not confirm a request if the information is unclear or different from the action you intended to perform.

Does disconnecting a website remove its token approvals?

Not necessarily.

Disconnecting WalletConnect ends the current connection between the wallet and the website.

Token approvals that were previously confirmed and recorded on the blockchain may remain active until they are separately revoked.

What happens if my NFC card is lost or damaged?

KEYRING cannot recover or replace the information stored on a lost or damaged NFC card.

If you have a backup file or the account’s private key, you can restore or import the account again.

Without the NFC card or another recovery method, you may permanently lose access to a Cold NFC Wallet account.

Should I create a backup before exporting an account to an NFC card?

Yes.

Create and safely store a backup file before converting an account into a Cold NFC Wallet.

You should also make sure you remember the backup-file password. This provides another recovery method if the NFC card is lost, damaged, or cannot be scanned.

What happens if I uninstall or reset KEYRING PRO?

Uninstalling the application or resetting the wallet removes the wallet information stored on that device.

It does not delete your assets from the blockchain.

To regain access, restore a KEYRING PRO backup file using the correct backup-file password or import each account again using its private key.

What should I do if my phone is lost or stolen?

Restore the wallet on a secure device using a KEYRING PRO backup file or the account private keys.

If you believe someone may be able to access the lost device, move your assets to newly created accounts as soon as possible.

Never provide your private key, wallet password, backup file, or backup-file password to anyone claiming to be KEYRING Support.

Does Face ID or fingerprint authentication replace my KEYRING PRO password?

No.

Biometric authentication provides a convenient way to unlock KEYRING PRO on a supported device. It does not replace your KEYRING PRO password.

You may still need the password for security-related actions, so it must be stored safely.

Can a custom RPC change my wallet address, private key, or assets?

No.

A custom RPC only changes the connection route used to communicate with the blockchain. It does not change your wallet address, private key, or assets.

However, an unreliable or malicious RPC may display incorrect information or interfere with blockchain requests. Only use RPC URLs from trusted sources.

What information should I provide when contacting KEYRING Support?

To help KEYRING Support identify and resolve an issue, provide:

• A screenshot or screen recording

• Your wallet or sub-account address

• The affected network and token

• The transaction hash, if available

• The complete error message

• Your KEYRING PRO version

• Your device model and operating system

• A brief description of the action you were trying to perform

Never provide your private key, KEYRING PRO password, backup file, or backup-file password.
