Payout network for USDT
The same USDT goes out in several networks. Rates and lower limits differ, and the fee is charged by the network itself.

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.
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.
OP Mainnet (Optimism) against Polygon PoS
| OP Mainnet (Optimism) | Polygon PoS | |
|---|---|---|
| Network type | L2, optimistic rollup | Sidechain with checkpoints in Ethereum |
| Fees are paid in | ETH | POL |
| Fee level | ≈ $0.00016 | ≈ $0.0017 |
| Speed | fast | fast |
| Block | ~2 sec | ~2 sec |
| Address shape | 0x… | 0x… |
| Memo or tag | not needed | not needed |
| Ethereum-style address (0x…) | yes | yes |
| Official withdrawal to Ethereum | ≈ 7 days (challenge period) | — |
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 | 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 |
