Kast BNB Chain Card, explained: USDT on BEP-20, BNB and getting money out
The Kast BNB Chain Card is the KAST Visa card funded over BNB Chain. KAST takes USDT on BEP-20 with no KAST fee and converts BNB on arrival. It is a deposit-only network, so withdrawals leave on Solana, TRON, Ethereum or Arbitrum.
What is the Kast BNB Chain Card?
The Kast BNB Chain Card is the regular KAST Visa card, topped up with USDT or BNB sent over BNB Chain. KAST announced the integration on 9 July 2025, describing it as a step toward a single place to save, send and spend stablecoins worldwide, and added BNB itself as a depositable coin that autumn.
It suits anyone whose funds sit on Binance or in a BNB Chain wallet, since USDT goes straight in without a bridge or an extra swap and network fees are a few cents.
How to deposit USDT on BNB Chain to KAST
Depositing USDT on BNB Chain to KAST takes a minute once your account is verified.
- In the KAST app, tap Receive and choose Stablecoin.
- Pick USDT, then BNB Chain from the network list.
- Copy the address with the copy button.
- Withdraw USDT on BEP-20 from your exchange or wallet to that address.
KAST charges nothing and credits it 1:1 in dollars, usually within minutes. At least $1 has to arrive after network fees. If you don't have an account yet, our Kast Card sign up page covers the ID check first.
Sending BNB to KAST
BNB sent to KAST is converted to stablecoins on arrival. Choose Crypto in the Receive screen, pick BNB and copy the address; the app shows an indicative price and explains that whatever reaches that address is sold for stablecoins automatically.
The conversion fee is shown before you confirm and usually lands between 2% and 5%. KAST puts it as "send BNB, spend stables."
What BNB Chain costs with KAST
USDT on BNB Chain costs nothing to deposit on KAST's side, and BNB Chain's own gas is usually a few cents. KAST groups it with Solana, TRON, Polygon and Stellar as a low-fee network that confirms in seconds.
After that, card payments in US dollars are free and other currencies carry a 0.5% to 1.75% FX fee. The full list is on our Kast Card fees page.
Getting money out when BNB Chain is deposit-only
KAST doesn't send stablecoins out on BNB Chain, so withdrawals go over another network. USDT can leave on Solana ($1 + 0.1%), TRON ($5 + 0.1%) or Ethereum ($6 + 0.1%), and USDC on Solana, Ethereum or Arbitrum ($0.20 + 0.1%).
Most exchanges accept USDT on Solana or TRON, so the usual route back to Binance is one of those. Our Kast Solana Card and Kast TRON Card pages walk through both.
Spending BNB Chain funds with the Kast Card
Once the deposit lands it is a dollar balance, usable anywhere Visa is accepted, online or in person. Cashback comes back in US dollars: up to 8%, with 1.5% on the free Standard tier and more on the paid tiers.
BEP-20 or ERC-20? Getting the network right
BNB Chain and Ethereum addresses both start with 0x, so a wallet won't stop you mixing them up. KAST's deposit screen says each address is unique to its network, so copy it only after you have picked USDT and BNB Chain.
If USDT goes out on the wrong network, recovery isn't guaranteed. When it is possible it takes 1 to 2 weeks, costs a fee, and the funds go back to the sending wallet.
