以最优汇率兑换 USDT 为 USDC

The exchange rate is very close to 1:1 since both are USD stablecoins. You'll pay a small exchange spread (0.1–0.5%) plus network fees. Total cost is typically $1–$5 depending on the networks used. On OneSwap.ai, the exact amount of USDC you'll receive is shown before you confirm.

Common reasons: USDC is preferred by certain DeFi protocols (Aave, Compound), USDC is required for some exchanges or on-ramps, USDC has more transparent reserves (audited by Deloitte), or you want to use the Coinbase/Base ecosystem where USDC is the native stablecoin.

USDT can be sent from TRC-20, ERC-20, BEP-20, Arbitrum, or Polygon. USDC can be received on Ethereum, Arbitrum, Base, Optimism, Solana, or Polygon. For the cheapest swap, send USDT from TRC-20 and receive USDC on Arbitrum or Base.

Very fast. Since both are stablecoins with no price volatility risk, exchange partners process these quickly. Typical time: 3–10 minutes depending on the source and destination networks.

Almost never. Stablecoin-to-stablecoin swaps are considered low-risk by exchange partners. KYC is extremely rare for this pair regardless of the amount.
