How to Spend Crypto with KuCard-AU?

Last updated: 04/17/2026 13:44:00

How KuCard transactions work?

KuCard enables eligible users to make card payments that are settled in standard currency (USDC), with the option to use supported crypto-assets as a funding source through conversion at the time of transaction.
Supported funding options currently include:
Standard currency: USDC
Supported crypto-assets (non-exhaustive list): BTC, ETH, XRP...
You may select which funding assets are available for KuCard transactions and define a priority order for how payments are funded. At least one funding asset (crypto) must remain enabled at all times in order to complete transactions.
Additional crypto-assets may be supported in the future, subject to regulatory approval and technical availability.
      
     

Payment priority and deduction order

When a KuCard transaction is initiated, funds are deducted based on the payment priority order set by you.
If no custom order is set, the default order applies:
USDC → BTC → ETH → KCS
If the balance of the first priority funding asset is insufficient, the system will automatically proceed to the next available option in the defined order.
  
Illustrative examples
Scenario 1 – Crypto balance sufficient
  • Payment amount: USDC 500 Available balances: USDC 1,000
  • Crypto-assets available but not required
  • Priority order: USDC → BTC → ETH
The transaction is fully funded using USDC from the Funding Account. No crypto-asset conversion is required.
  
Scenario 2 – Crypto balance sufficient
  • Payment amount: USDC 500 Available balances: USDC 100, ETH 0.6
  • Will be charged 0.25 ETH (assumed market price: 1 ETH = USDC 2000)
  • Additional crypto-assets available
The transaction is funded using:
0.25 ETH, converted into USDC at the applicable market sell price at the time of conversion. Conversion rates are subject to market conditions and may vary.
  • Available balances(After payment): USDC 100, ETH 0.35
  
Scenario 3 – Non-Crypto transaction (Fiat currency)
  • Transaction currency: AUD 100 Available balances: USDC 1,000
  • For Non-Crypto transactions:
The transaction amount is converted into USDC using KuCard Foreign Exchange Fee Rate at the time of processing.
Any remaining amount is funded using the next available funding asset based on your priority order.
Example (illustrative): If the applicable Mastercard exchange rate is 1% per transaction, USDC 69.5*(1+1%) equals approximately AUD 100.
USDC 70.195 is deducted from the Funding Account.
     
      

Important information

Authorisation and settlement When a transaction is authorised, the authorised amount is temporarily held in your Funding Account until the merchant completes settlement. If an authorisation is reversed or expires, the held amount is released back to your available balance.
Use of crypto-assets
  Each transaction may use USDC and at most one type of crypto-asset as a funding source.
  • Transactions cannot be split across multiple crypto-assets.
  • If the selected crypto-asset balance is insufficient, the system will automatically proceed to the next funding option based on your priority order. 
Regulatory clarification
KuCard transactions are settled in USDC.
Crypto-assets are used solely as a funding source via conversion and are not transferred to merchants.
Conversion rates, availability, and execution are subject to market conditions, applicable fees, and regulatory requirements.
