USDT network fees

How the USDC Polygon → USDT Optimism order runs

Work out the amount in the calculator and press the exchange button.
Enter a USDT address in Optimism and a way to reach you.
Send USDC Polygon in Polygon 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 Polygon for USDT Optimism

Check this before sending USDC Polygon

The address network is Optimism. Sending through another network usually means losing the transfer.
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 OP Mainnet (Optimism).
To move USDT on later, put a little ETH at the same address.
Coins go through an AML check: a flagged transfer can be held until the check is finished.

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 OP Mainnet (Optimism)	Not needed to receive	Often needed, or the funds cannot be claimed or moved on
Timing	After confirmations in Polygon PoS; the order page tracks it	Depends on the bridge and the load of both networks
