Cosine Wallet Integrates Unigox: Buy & Sell USDT In 30 Countries
Published on 10th of September 2026 by Unigox Team
Cosine Wallet, a self-custody mobile wallet on iOS and Android, has integrated Unigox as its fiat on- and off-ramp. Cosine users can now sell USDT straight to a local bank account, or buy USDT with local currency, without leaving the app. For the launch, every Unigox-routed transaction in Cosine Wallet runs at 0% added fees from 10th to 24th September 2026.
What changed for Cosine users
Until now, a Cosine user who wanted to cash out USDT in Lahore or Dhaka had to move funds to an exchange, sell there, and withdraw. Three apps, three sets of fees. With Unigox inside the wallet it's one flow: pick USDT, pick your currency, choose bank transfer, confirm. Unigox handles the corridor, the compliance checks and the payout.
The integration opens fiat corridors that Cosine's existing partners didn't cover:
- New sell markets: Bangladesh, Canada, Egypt, Ethiopia, Germany, Guinea, Kazakhstan, Kuwait, Pakistan, Sri Lanka
- New buy market: Sri Lanka
It also adds a second route in markets Cosine already served. That matters when one rail is slow or a bank is having a bad day.
- Buy: Germany, Mexico, South Africa
- Sell: Argentina, Cameroon, China, DR Congo, Ghana, India, Indonesia, Kenya, Mexico, Nigeria, Philippines, Rwanda, Saudi Arabia, Senegal, Sierra Leone, South Africa, Tanzania, Uganda, United States, Vietnam
That's 30 sell corridors and 4 buy corridors live from day one. If you want to check a rate first, our converters for USDT to NGN, USDT to INR and USDT to KES show the same Unigox rate you'll see in the app.
The launch promo: 0% added fees for 14 days
From 10th to 24th September 2026, Cosine Wallet is waiving its own fees on every transaction routed through Unigox. All buy and sell orders, every supported country, no volume cap. You pay the Unigox rate you see on screen and nothing on top.
How it works
- Open Cosine Wallet and tap Sell (or Buy).
- Choose USDT and the amount. Cosine shows the live Unigox rate. At the time of writing, 300 USDT gets you 409,376 NGN.
- Select Bank Transfer and the account you want paid.
- Confirm. Cosine hands the order to Unigox, it settles, and the money lands in your bank account.

"Wallets shouldn't have to build a payout network country by country. Cosine plugged into ours and switched on 30 corridors at once. That's the whole point of Unigox." Artur, Co-founder, Unigox
