USDC network fees

How the USDT ERC20 → USDC Polygon order runs

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

Swap USDT ERC20 for USDC Polygon

Check this before sending USDT ERC20

The address network is Polygon. Sending through another network usually means losing the transfer.
The transfer must not be smaller than 100 USDT 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 USDC 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.

Fee and speed levels are comparative: both move with how busy the network is.

How this differs from a classic bridge

	RubyCash	Classic bridge
What lands at your address	USDC in Polygon PoS	The same stablecoin; turning USDT into USDC is a separate step
Wallet and signatures	Not needed: the coins go to the address from the order	Needed: connect the wallet and sign contract transactions
A coin for fees in Polygon PoS	Not needed to receive	Often needed, or the funds cannot be claimed or moved on
Timing	After confirmations in Ethereum; the order page tracks it	Depends on the bridge and the load of both networks
Who holds the funds meanwhile	RubyCash for the life of the order, with an AML check	The bridge contract or its validators

Common questions: USDT ERC20 → USDC Polygon

What rate does USDT ERC20 to USDC Polygon run at?

As of Nov 2, 2026 00:19 it is 1 USDT ERC20 = 0.997495 USDC Polygon. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $0.997224.

What amounts does USDT ERC20 → USDC Polygon accept?

From 100 to 10,000,000 USDT ERC20 per order. The lower limit is roughly $99.92.

Where does the 100 USDT ERC20 floor come from?

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

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 USDT ERC20, and that one goes to the blockchain, not to us.

How long does USDT ERC20 to USDC 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.

Will native USDC arrive, or a wrapper?

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

Do I need POL to receive USDC Polygon?

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

Which network will USDC Polygon arrive in?

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

Where is receiving USDC cheaper?

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

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.

What did the USDT ERC20 to USDC Polygon rate do this month?

The month came in at minus 0.03%. Low 0.999117, high 0.999991, middle 0.999544 USDC Polygon per USDT ERC20.

Can I go back, USDC Polygon to USDT ERC20?

Yes, the reverse direction is open: 1 USDC Polygon = 0.999489 USDT ERC20. The link sits right under the calculator.
