FAQ
What is Passkey?
A passkey is a modern, secure way to log in to apps and websites without a traditional password. It uses biometric authentication (like your fingerprint or face ID) or a PIN on your trusted device.
Is KEYRING DeCard safe?
Yes, it is! The KEYRING DeCard uses Passkey as its primary security method. To perform any transaction, users must authenticate themselves through their Passkey—such as a fingerprint, Face ID, or the PIN code of their trusted device.
Even if your device is lost, no one else can access your KEYRING DeCard unless they have your Passkey. This ensures that your funds and wallet remain secure, providing peace of mind in protecting your assets.
Why must I register an image and nickname when creating an account?
You don’t have to! This step is optional during the account creation process. It’s part of a feature we call the Address Book NFT.
Here’s how it works:
If you choose to provide an image and nickname, we’ll use this information to create a personalized NFT for your account.
This NFT helps you customize your account and makes managing it more convenient.
Additionally, it enhances transaction clarity: other KEYRING DeCard users can easily identify you during transactions, reducing errors when entering recipient details.
So while it’s optional, it’s a great way to personalize your experience and streamline your wallet usage!
What is an Address Book NFT?
The Address Book NFT is a feature that personalizes your account by turning your image and nickname into a unique NFT.
This NFT acts as a profile for your wallet, making it easier for others to identify you during transactions and reducing errors when sending funds.
It’s an optional but practical way to enhance your wallet’s usability and identity on the blockchain.
Why sometimes I have to confirm via Passkey twice, and other times it's only once?
The number of Passkey confirmations depends on the relationship between the token being sent and the gas token's blockchain.
Single Passkey Verification: This happens when the token you’re sending and the token you’re using to pay the gas fee are on the same blockchain.
Double Passkey Verification: This is required when the token you’re sending and the gas fee token are on different blockchains.
This ensures extra security and clarity for cross-chain transactions, minimizing errors and keeping your assets safe.
Can the same account be used on multiple devices?
Yes, you can use the same account on multiple devices, provided they are compatible. Here's how it works for different platforms:
For iOS Devices: If your devices share the same iCloud account, your Passkey is stored and synced through iCloud. This allows seamless login to the same KEYRING DeCard across multiple Apple devices.
For Android Devices: If your devices use the same Google account, your Passkey will be synced via Google services, enabling access to your wallet on multiple Android devices.
For Windows PCs: Copy the wallet URL from your Android device and paste it into Chrome on your PC. To access the wallet, ensure you are signed in to the same Google account on both your Android device and Chrome browser.
We recommend creating your account on a mobile device to ensure the best experience with KEYRING DeCard.
Can I use any ERC-20 Token as a Gas Token?
Not all ERC-20 tokens are supported. Currently, KEYRING DeCard supports ERC-20 tokens on the following five chains:
Ethereum
Optimism
Binance Smart Chain (BSC)
Polygon
Arbitrum
Additionally, whether a token can be used as a gas token depends on the initial configuration set by our partners. Ensure the token you wish to use is compatible with these chains and meets the specific requirements for gas payments.
If I delete my cache on my device, will I lose my account?
No, your account is safe. The KEYRING DeCard is linked to your device’s Passkey, not its cache or browsing history. Deleting your cache will not impact your wallet.
However, please note:
Since the wallet relies on your Passkey, deleting or changing your Passkey may result in losing access to your wallet.
To prevent issues, always keep your Passkey secure and intact.
If you change your Passkey and can no longer access your wallet, please contact us at info@bacoor.co. We’ll provide detailed instructions on how to regain access to your account.
Why must I enter so many passwords/codes on Windows PCs?
Creating and logging into wallets on mobile devices tends to be simpler because passkeys are better optimized for phones.
For Windows PCs, wallet creation must be done through the Chrome browser. As a result, you need to follow Google's and Chrome's security procedures, which require multiple passkey verifications.
However, once the wallet is successfully created, you won't need to verify as often.
This is part of Google and Chrome's security protocol, and KEYRING DeCard cannot change or decide these steps.
Why Do I Keep Getting Asked to Verify with Passkey on My Phone?
You might be asked to verify with a passkey when you use different Google accounts on your phone and Chrome.
For example, if you create a wallet with Google account A on your phone but use Google account B on Chrome, you'll need to verify with your phone.
How to Avoid This:
Use the same Google account on both your phone and Chrome.
Or create a new wallet using the Google account on Chrome.
This way, you won't need to verify with your phone each time.
Why Do I Need to Delete the Old Passkey to Create a New One on Windows?
This is a required Google process that KEYRING DeCard cannot change. Before creating a new one, you need to delete the old passkey to ensure the account is clear.
Rest assured, the passkeys on your phone or computer remain unchanged. This only applies to the Google account used for wallet creation. Once the new passkey is created, you won't need to repeat this step.
Why do I still use my machine's PIN Code when logging in, even after creating a new passkey for the wallet on Windows?
When you create a passkey, it's saved to your Google account. When logging into Chrome on another computer, you'll use this passkey. This is also your recovery key.
After logging in, if your Windows PC has a PIN code, you'll need to enter it each time you log into the wallet. If it doesn't, you won't need to.
Can I transfer funds from my wallet to an Exchange?
No, you cannot. KEYRING DeCard t is not a typical web3 wallet; it uses an ERC-4337 Smart Contract Wallet.
Why Not? ERC-4337 wallets should avoid direct transfers to exchanges because:
Specific Deposit Procedures: Exchanges often require unique deposit addresses or memos/tags for certain assets. Missing these steps can result in lost or irrecoverable tokens.
Compatibility Issues: ERC-4337 wallets operate as smart contracts, which might not align with the exchange's standard transaction handling, causing failed deposits.
Recommendation:
Always confirm the exchange's requirements before transferring.
We do not recommend making direct transactions from KEYRING DeCard to an exchange to avoid loss of assets.
Important Note: If users ignore this warning and directly transfer from KEYRING DeCard to an exchange, resulting in asset loss, KEYRING DeCard will not be held responsible.
What is ERC-4337?
ERC-4337, or Account Abstraction, enables smart contract wallets on Ethereum to function as programmable, secure, and user-friendly accounts.
Unlike traditional wallets tied to private keys (EOAs), ERC-4337 wallets are flexible, allowing features like gasless transactions, custom security rules, and token storage.
It simplifies wallet usage by automating actions and enabling advanced features while maintaining full decentralization.
How to Transfer Funds to an Exchange
Since you cannot directly transfer funds from KEYRING DeCard to an exchange, you will need to use an indirect method:
Transfer your funds to a standard web3 wallet, such as KEYRING PRO Wallet, MetaMask, or Trust Wallet.
From the standard web3 wallet, send your funds to the exchange.
This extra step might seem inconvenient, but it ensures the safety of your assets. Sacrificing a bit of convenience is worth it for the added security.
If I Lose My Device, Can I Recover My Wallet?
Yes, you can.
For iOS Devices:
Your wallet is linked to your iCloud account.
Simply log in to another iOS device using the same iCloud account to access your wallet.
For Android and Windows Devices:
Your wallet passkey is saved to your Google account.
Log in to another device using the same Google account to recover your wallet.
This ensures that you can always access your wallet, even if you lose your device.
Can I use other methods to create a passkey on my Window?
No, you must use Google Passkey Manager to create a passkey for your wallet. Any other method won't work.
How to Recover My Wallet if I Lose or Change My Passkey?
DeCard offers a unique advantage: even though it’s a Smart Wallet (ERC-4337), you can still recover your wallet by extracting the Private Key. This is helpful if you lose your Passkey or switch to a new device.
To recover your wallet:
Contact Us: Send an email to info@bacoor.co.
Follow Instructions: We will provide step-by-step guidance for the recovery process.
Important: Wallet recovery is only possible if you still have your DeCard. If both the Passkey and the DeCard are lost, recovery cannot be done.
Keep your DeCard safe—it’s essential for securing your assets!
What If I Lose My Card?
For the ERC-4337 Smart Wallet, the wallet does not have a traditional Private Key, as it is encrypted within the Passkey. The user's passkey acts as the key to access the wallet.
To provide an additional backup option for users, KEYRING DeCard links the wallet's Passkey to a Private Key—similar to a non-custodial wallet. This allows users to access their wallet if they change their Passkey.
If you lose your DeCard physical card, you can still access and use your wallet, provided your Passkey remains unchanged. All you need is to save the wallet's URL (e.g., bookmark it or create an app shortcut) to continue accessing it.
However, if both the Passkey and the card are lost, there is no way to access the wallet.
How Can I Find My Wallet URL?
Since the KEYRING DeCard is a web-based wallet, it doesn’t have a separate app. Instead, it works directly in the web browser, and each wallet has a unique URL.
Here are ways to access your wallet:
Tap the card on your device (make sure NFC is enabled) to be directed to the wallet page.
Bookmark the wallet URL for quick access.
On mobile devices, you can create a shortcut to the wallet on your home screen.
