Fizen Super App vs Bitget Wallet: How to Spend USDT in Vietnam

Fizen Super App vs Bitget Wallet compared: both pay Vietnamese merchants with USDT by QR. Coverage, chains, and which to choose.

You hold USDT and you are in Vietnam. The two apps that let you walk up to a shop and pay a merchant directly by QR code with stablecoins are the Fizen Super App and Bitget Wallet. Both plug into VietQR, both are non-custodial, and both convert your stablecoins to Vietnamese dong for the merchant. So which should you actually use?

Here is an honest, side-by-side look. If you also want to see how Fizen compares with LocalPay and Moreta Pay, we cover that in a separate QR Pay comparison.

Short version: Both are non-custodial and both let you scan a national QR code and pay merchants with USDT. Bitget Wallet is the broader crypto wallet, with national QR pay across Vietnam, the Philippines, and Brazil and support for many chains. The Fizen Super App is the simpler all-in-one choice for everyday spending: QR Pay in Vietnam and the Philippines, plus a Visa card, eSIM, and tokenized stocks on one USDT balance, backed by Tether, with easy in-app funding by card or bank.

Fizen Super App

The Fizen Super App lets you scan a VietQR code and pay a merchant directly through its QR Pay feature, so the merchant receives Vietnamese dong while you spend USDT on BNB Chain or Solana. Topping up on BNB Chain has no gas fee, and you can fund the app on-chain or buy USDT inside it with a Visa card or a bank transfer through P2P, so you do not need a separate exchange. It is non-custodial and backed by Tether.

QR Pay is not a separate download. There is no standalone "Fizen QR Pay" app, you get the one Fizen Super App and QR Pay is built in. The same USDT balance also runs a Visa Prepaid card, eSIM data, and access to tokenized stocks, and QR Pay works in the Philippines too, not only Vietnam. That all-in-one simplicity, on one balance, is what sets it apart.

Bitget Wallet

Bitget Wallet integrates with VietQR and lets you scan to pay across a large network of locations, converting your crypto to dong at checkout through its payment partner. It supports USDT and USDC across several chains including Ethereum, BNB Chain, Solana, Tron, Base, and TON, and beyond Vietnam it also runs national QR pay in the Philippines and Brazil. It is a full multichain wallet with swaps, DApps, and its own card, with regular cashback campaigns for eligible users. If you want one big self-custody wallet that also handles QR pay, it is a strong, broad option.

How they really differ

For paying a merchant in Vietnam, the two feel almost identical: scan, confirm, done. The difference is what surrounds the payment. Bitget Wallet is built first as a large multichain wallet, with many chains, swaps, DApps, and national QR pay across Vietnam, the Philippines, and Brazil, so it shines if you already manage tokens across chains and want wide coverage. The Fizen Super App is built first for spending: the same USDT balance you pay with also powers a Visa Prepaid card, eSIM data, and access to tokenized stocks, and you can fund it by buying USDT in-app with a card or bank transfer. It is backed by Tether. So the honest split is the breadth of a crypto wallet (Bitget) versus the simplicity of an all-in-one spending app (Fizen). If Trust Wallet QR was your old method, note that it was discontinued in March 2026, which is part of why both of these are worth a look now.

Which should you choose

Choose Bitget Wallet if you want one powerful multichain self-custody wallet that also pays by national QR across several countries. Choose the Fizen Super App if you want the simplest way to live on USDT day to day: pay by QR in Vietnam and the Philippines, swipe a Visa card anywhere Visa is accepted, grab an eSIM, and fund it all with a card or bank transfer, on one balance, backed by Tether.
