Stablecoins from Ethereum to Polygon PoS: USDC ERC20 → USDT Polygon

Q: What rate does USDC ERC20 to USDT Polygon run at?

As of Sep 17, 2026 10:28 it is 1 USDC ERC20 = 1.0018 USDT Polygon. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $1.00.

Q: What amounts does USDC ERC20 → USDT Polygon accept?

From 100 to 10,000,000 USDC ERC20 per order. The lower limit is roughly $99.96.

Q: Where does the 100 USDC ERC20 floor come from?

Network fees and order handling eat a small transfer alive — below 100 USDC ERC20 the swap stops making sense for either side.

Q: What else is taken on top of the rate?

The payout is already calculated at the rate in the calculator. On top of it you only pay the network fee for sending USDC ERC20, and that one goes to the blockchain, not to us.

Q: How long does USDC ERC20 to USDT Polygon take?

The clock starts with confirmations: the order goes into work once Ethereum (ERC20) confirms your transfer. After that it comes down to how busy the network is. A block in Ethereum (ERC20) closes in about 12 sec.

Q: Will native USDT arrive, or a wrapper?

USDT Polygon is the standard USDT token in Polygon PoS — exactly what exchanges send when they withdraw into this network.

Q: Do I need POL to receive USDT Polygon?

Not to receive. POL comes into play later, when you want to send USDT from your address.

Q: Which network will USDT Polygon arrive in?

The payout leaves in Polygon. Make sure the receiving wallet works with that network.

Q: Where is receiving USDT cheaper?

The cheapest is usually USDT SOL, USDT Polygon, USDT Arbitrum, USDT TON, USDT BEP20, USDT AVAX C, USDT Optimism. Still, the network is chosen by what the recipient supports, not by the fee.

Q: What if the rate moves while I am paying?

The rate is pinned to the order and does not move while the order is alive. It can be recalculated if the payment arrives late or for a different amount — so send the exact sum, and send it promptly.

USDT network fees

How the USDC ERC20 → USDT Polygon order runs

Work out the amount in the calculator: orders start at 100 USDC ERC20.
Enter a USDT address in Polygon and a way to reach you.
Send USDC ERC20 in Ethereum (ERC20) for exactly the amount stated in the order.
Once the network confirms your transfer, Tether leaves for your address. The order page tracks every step.

Swap USDC ERC20 for USDT Polygon

Check this before sending USDC ERC20

The address network is Polygon. Sending through another network usually means losing the transfer.
The transfer must not be smaller than 100 USDC ERC20.
Copy the address whole, then compare the first and last characters after pasting.
Ethereum, Arbitrum, Optimism, BNB Smart Chain and Polygon all use the same address shape (0x…). Make sure the wallet is switched to Polygon PoS.
To move USDT on later, put a little POL at the same address.
Coins go through an AML check: a flagged transfer can be held until the check is finished.
