Simplex and the Unigox Crypto widget for a stablecoin sale
| Topic | Simplex | Unigox |
|---|---|---|
| How you add it | For sells, a link or button that sends the user to Simplex's Sell widget with your referral ID. No back-end work, and the sale finishes on Simplex's page. Buys use an iFrame, the Wallet API or a JWT integration. | One embed code with your widget key; the widget opens inside your site. Unigox runs sign-up, identity checks and the trade. |
| What users can sell | BTC and USDT on Tron, as Simplex's Sell tutorial lists them, through a link to its sell widget. | USDT or USDC from the user's Unigox Wallet. USDT can arrive on Tron, Solana, TON or EVM networks such as Ethereum and BNB Smart Chain. |
| Where the sale is paid | To the user's Visa or Mastercard card, or to a SEPA account. | To the user's bank or mobile money account in local currency, sent by the P2P merchant or payment business that buys the stablecoins. |
| What users pay | No fee table. Simplex's terms say it charges no fee for the Simplex Service itself and shows any fee of its own before charging; the crypto-asset service provider that completes the purchase charges fees under its own terms. | A rate with the Unigox fee inside it, shown before the user confirms. |
| What you earn | Not published. Businesses get in touch through Simplex's partner page. | Your cut is 20% of the Unigox fee per completed trade, paid as agreed at setup. On sells you can add your own markup, credited in crypto to the partner wallet. |
