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 S to FIRE Without Registration or KYC

Exchange S to FIRE without an account or personal data for standard amounts. Transactions on Sonic and Polygon POS 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 S to FIRE exchange runs without verification.

Transparent S to FIRE 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 Polygon POS network fee. Nothing else.

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

Instant S to FIRE swap

Exchanging S to FIRE 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 S to complete your swap.

Purchase S for FIRE easy and simple!
