Pay and receive Pix using
digital dollars (USDT).
Charge via Pix with direct USDT settlement, in a wallet you fully control. 100% self-custody: UnePay never has access to your funds.
We are the bridge between the real economy and the digital economy: charge and pay any Pix using digital dollars, with instant settlement on both sides.
You hold USDT
USDT is a digital dollar on the Polygon network. Always worth 1 to 1 with the US dollar, without the swings of bitcoin.
Pay any Pix instantly
QR code, Pix copy-paste, or key (CPF, CNPJ...): the wallet converts your USDT and pays directly, at the gas station, the pharmacy, wherever. Instant payment, confirmed right away.
The balance is yours, not UnePay's
Your wallet follows the BIP39 standard, the same one used across the market. You can import the same wallet into Trust Wallet, MetaMask, Rabby, Phantom and others, anytime.
Charge anyone via Pix
Generate a charge and receive with direct USDT settlement, in the wallet you configure. We help on the payout side too.

Frequently asked questions
No. You just need to know you hold digital dollars in the wallet and can turn them into a Pix payment anytime, instantly.
No. The balance is yours. Your wallet follows the BIP39 standard and can be imported into Trust Wallet, MetaMask, Rabby, Phantom and other standard wallets at any time.
Converting USDT to Pix has a simple fee, shown before every payment. No surprises at confirmation.
You recover the wallet on any device, or in any BIP39-compatible wallet, with your 12-word phrase. Keep it on paper, somewhere safe.
No. Your entire balance stays in your self-custody wallet. With your 12-word phrase you can import the wallet into any other app (Trust Wallet, MetaMask...) and your digital-dollar balance will be there, independent of UnePay.
No. When your customer pays the Pix you charged, the payment goes out under our conversion partner's name (the tokenizer). The amount is converted automatically and sent straight to your wallet.
After the Pix is paid, it takes about 15 seconds to land in your self-custody wallet. Paying a Pix (QR code, copy-paste, or key) takes about 25 seconds.
No. When you create your account, you can import a wallet you already have or create a new one right inside the app — conversion between Pix and USDT happens automatically.
We use blockchain, the most secure technology in the world — to date there's no known way to break it. The real risk is how you store your 12-word phrase: lose it, and you lose access to your balance — not even UnePay can recover it.
Depends on your document: we accept CPF (Brazil), DNI (Argentina), or CI (Paraguay).
We use USDT on the Polygon network.
It's the world's most used and liquid stablecoin — over $13 trillion moved in 2025 alone, supported by practically every exchange and wallet in the market.
