How the USDC Optimism → USDT SOL order runs
- Work out the amount in the calculator: orders start at 200 USDC Optimism.
- Enter a USDT address in Solana 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 Solana. 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.
- To move USDT on later, put a little SOL 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 Solana | 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 Solana | 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 |

Common questions: USDC Optimism → USDT SOL
What rate does USDC Optimism to USDT SOL run at?
As of Sep 17, 2026 04:58 it is 1 USDC Optimism = 1.0007 USDT SOL. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $1.00.
What amounts does USDC Optimism → USDT SOL accept?
From 200 to 10,000,000 USDC Optimism per order. The lower limit is roughly $199.93.
Where does the 200 USDC Optimism floor come from?
Network fees and order handling eat a small transfer alive — below 200 USDC Optimism 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 USDC Optimism, and that one goes to the blockchain, not to us.
How long does USDC Optimism to USDT SOL take?
The clock starts with confirmations: the order goes into work once Optimism confirms your transfer. After that it comes down to how busy the network is. A block in Optimism closes in about 2 sec.
Will native USDT arrive, or a wrapper?
USDT SOL is the standard USDT token in Solana — exactly what exchanges send when they withdraw into this network.
Do I need SOL to receive USDT SOL?
Not to receive. SOL comes into play later, when you want to send USDT from your address.
Which network will USDT SOL arrive in?
The payout leaves in Solana. Make sure the receiving wallet works with that network.
Where is receiving USDT cheaper?
The cheapest is usually USDT BEP20, USDT SOL, USDT Polygon, USDT Arbitrum, USDT TON, USDT AVAX C, USDT 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.
Can I go back, USDT SOL to USDC Optimism?
Yes, the reverse direction is open: 1 USDT SOL = 0.9995 USDC Optimism. The link sits right under the calculator.
