⚡ Quick summary (TL;DR)
Manage Pay balance, transfers into MPCard, spending, and transfers out so balances stay clear day to day.
Keep egress region, billing address, and card details aligned; leave a balance buffer; do not rapid-retry payments.
This guide is for MPChat Pay & MPCard (Cloud / Boundless).
📖 Overview
Understand the fund flow of MPChat in one article: Pay → card → spend → transfer back. It is suitable for users who have just opened a card and want to figure out "where the money is and how to move it."
MPChat's funds are divided into two layers: Pay balance (your asset account) and card balance (each card is independent). Understand the relationship between these two levels, and you will not get lost when using cards.
The Asset page has two tabs: Pay and Web3. Card opening, deposits, card spending, and transfers out use Pay balance only; assets in the Web3 tab are not used for cards.

Deposit into Pay
First deposit USDT into MPChat Pay, and the system will convert it into USD based on the then-current exchange rate (1 USDT usually converts to about 0.993–0.998 USD) and credit it to Pay balance. Two ways:
On-chain deposit (USDT): Withdraw coins from the exchange or wallet to the MPChat payment address. For details, see "How do I top up (deposit) my MPChat Asset? 》.
Binance Pay recharge: For details, see "How to use Binance Pay to recharge to MPChat account?" 》.
The minimum on-chain deposit is 15 USDT. If the amount actually received after the sending platform's withdrawal/network fees is below 10 USDT, HashKey cannot credit it and will not return it, even if the amount entered when sending was 15 USDT. This applies to USDT on Tron (TRC20), BNB Smart Chain (BEP20) and Ethereum (ERC20). Match the network selected in MPChat and check the net received amount before sending.
Transfer from Pay to the card
After opening the card, the balance of the card will be used for consumption, and the Pay balance needs to be transferred to the card first.
Path: Card page → "Recharge/Transfer", select the target card and enter the amount.
Cost and timeliness: Transfers between Pay and cards are instant and free.
For details, see "How to add money to the card after opening the card?" 》What is the difference between "Transfer" and "Top-up"? Is there a fee?.
Card consumption and automatic currency exchange
The card is settled in USD; when spending in non-USD areas, the bank will automatically convert it into the local currency.
The actual deduction for each purchase = consumption amount + handling fee (non-USD spending also incurs FX). Including the USDT conversion difference, USD spending is usually about 1% all-in and non-USD spending about 1.8%–2.2%, subject to actual rates. Please ensure that the balance in the card is sufficient (it is recommended to reserve a buffer).
For details such as cross-border fees and handling fees, please refer to the "MPCard Cross-border Exchange Rate and Handling Fee Instructions".
⚠️ Insufficient balance will cause the payment to fail and will not cause the card to be frozen; please make up the balance in time and try again.
Transfer card balance back to Pay
Money you don’t want to keep on the card can be transferred back to Pay balance.
Path: Card page → "Transfer/Swap" to transfer the card USD balance back to Pay.
Minimum retained balance: The card balance must be transferred back to Pay before cash can be withdrawn; when transferring out, refer to the "Transferable Balance" on the card details page. Insufficient balance will only cause the transaction to fail/reject payment, but will not cause the card to be frozen.
