I accidentally made two transactions to the same address when I made a swap at Quickex. I contacted their support agent via chat and described the situation. After I provide requested proof I was told to wait. Eventually, the second transaction that I send by mistake was returned to me! Thank you for good support and honest service!

I exchanged BTC to TRX, and the speed was satisfactory. I initially checked with support regarding the large amount and was assured there would be no issues, and that my transaction would be monitored. Everything went smoothly indeed. I plan to keep using this platform.

Exchange SPA to USDC Without Registration or KYC

Exchange SPA to USDC without an account or personal data for standard amounts. Transactions on ERC20 and Sonic are public on-chain — we don’t ask for name, email or documents, but the transfer is visible on the network.

KYC is requested only if a transaction is flagged by the system as suspicious — to prevent fraud. In all other cases, the SPA to USDC exchange runs without verification.

Transparent SPA to USDC exchange rate with no hidden fees

You see the final amount before you confirm. The fee is 1% on a Fixed rate or 0.5% on a Floating rate, plus the Sonic network fee. Nothing else.

The converter polls liquidity providers in real time and shows the best SPA to USDC rate. The selected rate is locked when you create the order and does not float during payment (for the Fixed type).

Instant SPA to USDC swap

Exchanging SPA to USDC takes 4 steps and on average 5–10 minutes after network confirmation.

Just a few steps – choose the pair , enter the amount and wallet address, and send SPA to complete your swap.
