Introducing the KEYRING SMART DeCard
What is KEYRING SMART DeCard?
KEYRING SMART DeCard is an innovative product developed by BACOOR, utilizing advanced passkey technology and the ERC-4337 standard. Eliminating the need for native gas fee tokens and key management removes common barriers for new users and significantly improves accessibility.
This is a web-based app, accessible from any device that supports a browser, providing users with seamless, cross-platform access.
Powered by Passkey Technology
Passkeys provide secure access by encrypting private keys using biometric data, ensuring that only authenticated users can access the wallet.
KEYRING SMART DeCard allows you to generate a wallet using passkey technology. Since the passkey generates and encrypts the wallet, users do not need to remember or store a private key.
The key is securely linked to the user's biometric data.
How to Create a Keyring DeCart Wallet?
The process of creating a Keyring DeCard Wallet is simple and quick. Follow these steps:
Enable NFC: Turn on the NFC function on your device.
Scan the DeCard: Use your device's NFC function to scan the DeCard.
Access the Wallet Creation Page: You'll be directed to a page designed to create a wallet compatible with your DeCard.
Activate Your Account: Select "Activate Account" to begin the setup process.
(Optional) Create an Address Book NFT:

This helps you easily manage your wallet accounts on the device.

Use your fingerprint or Face ID to secure it.

You'll have your Keyring DeCard Wallet ready for use in just a few steps!
How to Receive Token
Receiving tokens is very simple:
Tap the QR code icon in the top-right corner.
Users will see the QR code of their wallet address.
The sender can scan this QR code directly to get the wallet address.
Alternatively, tap the "Copy" button below the QR code and share the copied address with the sender.
How to Send Token
Follow these steps to send tokens:
Select the token you want to send.
Enter the recipient's address.
Input the number of tokens you wish to send.
Choose the Execution Cost by selecting the ERC-20 token you want to use for the gas fee.
Tap "Send".
If the Gas Fee Token is on a different chain than the Token to be sent
Verify the gas fee transaction using your passkey.
Once the gas fee transaction is completed, the token transfer will begin automatically.
Verify the token transfer transaction using your passkey.
Wait for the transaction to complete, and the token transfer will be successful.
Important Notice
The KEYRING DeCard is an ERC-4337 Smart Wallet. While it allows seamless asset transfers between different wallets, it cannot directly send assets to exchanges (like Binance, Coinbase, Kraken, etc.) These exchanges may interpret an ERC-4337 Smart Wallet as a standard wallet, causing transactions to fail. This could result in the loss of assets, which cannot be recovered.
To prevent loss, please do not send assets directly from your KEYRING DeCard to any exchange.
If users disregard this warning and lose their assets, KEYRING DeCard will not be responsible for the loss.
How to Send NFT
Sending NFT is fairly similar to sending regular tokens since NFT is also just a different form of token.
Switch to the NFT tab.
Choose the network that has the NFT you want to send.
Choose the NFT
Tap "Send"
Input the recipient's address.
Input the quantity of the NFT you want to send.
Choose the token for the Execution Cost. Tap "Send"
If the Gas Fee Token is on a different chain than the NFT to be sent
Verify the gas fee transaction using your passkey.
Once the gas fee transaction is completed, the NFT transfer will begin automatically.
Verify the NFT transfer transaction using your passkey.
Wait for the transaction to complete, and the NFT transfer will be successful.
How to Exchange Token
Token exchange can be done in two ways: Swap and Bridge.
Swap: Exchange one token for another on the same blockchain.
Bridge: Transfer tokens across different blockchains. You can either keep the same token or exchange it for a different one.
To exchange tokens using the KEYRING DeCard wallet, follow these steps:
Select the token you want to exchange.
Switch to the Exchange tab.
Choose the Execution Cost (gas fee).
Select the output blockchain.
Choose the output token.
Enter the number of tokens to exchange.
(Optional) Adjust Slippage (the allowable price difference during the exchange). A wider slippage range prioritizes the transaction.
Confirm the exchange.
If the Gas Fee Token is on a different chain than the Token to be exchanged
Verify the gas fee transaction using your passkey.
Once the gas fee transaction is completed, the token exchange transaction will begin automatically.
Verify the token exchange transaction using your passkey.
Wait for the transaction to complete, and the token will be exchanged.
How to Recover Your Wallet if You Lose or Change Your 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!
