USDC on Solana

Fixed rate

The receive amount shown at order creation is what you get if the deposit rules are met.

• 0.8% service fee + network fee.
• Quoted rate held for about 10 minutes.
• If the market moves more than ~1% before your payment appears on-chain, you can refund or continue at the then-current market rate.

Note: Deposit amount and timing must match the order. Mismatches force a refund or market-rate continuation prompt.

Float rate

The final rate locks after your deposit reaches required confirmations. Markets up → you may receive more; markets down → less.

• 0.4% service fee + network fee.
• Final rate is set within about 10 minutes after the needed confirmations.

Example: You swap ~1,000 USDT for an estimated 0.015 BTC on ToSwap. Fixed pays exactly that BTC figure; float can land higher or lower with the market.
