How the USDC Optimism → USDT Polygon order runs

Work out the amount in the calculator: orders start at 200 USDC Optimism.
Enter a USDT address in Polygon and a way to reach you.
Send USDC Optimism in Optimism 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 Optimism for USDT Polygon

Check this before sending USDC Optimism

The address network is Polygon. Sending through another network usually means losing the transfer.
The transfer must not be smaller than 200 USDC Optimism.
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.

How this differs from a classic bridge

	RubyCash	Classic bridge
What lands at your address	USDT 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 OP Mainnet (Optimism); 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
