The figure is indicative; the exact amount is locked in the order.
One USDC ERC20 buys 1.0001 USDC Optimism right now; the other way round, 1 USDC Optimism is 0.9999 USDC ERC20. Market over 24 hours: USDC ERC20 against USDC Optimism a move of 0%. The week added a move of 0%.
The weekly corridor ran from 1 to 1 USDC Optimism, a spread of 0%.
The payout leaves in the Optimism network, so the receiving address has to belong to that network.
Who takes the USDC ERC20 → USDC Optimism route
- Moving between networksUSDC in Ethereum (ERC20) (fee ≈ $0.0081) becomes Optimism (fee ≈ $0.00016) — the usual way to top up a wallet or an exchange that speaks one network only.
- A road both waysThe USDC Optimism → USDC ERC20 direction is open too, so going back into USDC takes the same route.

Payout network for USDC
The same USDC goes out in several networks. Rates and lower limits differ, and the fee is charged by the network itself.
| Network | Per USDC ERC20 | From | Network fee | Speed |
|---|---|---|---|---|
| Polygon | 0.9999 | 10,500 USDC ERC20 | ≈ $0.0017 | fast |

How the USDC ERC20 → USDC Optimism order runs
- Work out the amount in the calculator and press the exchange button.
- Enter a USDC address in Optimism and a way to reach you.
- Send USDC ERC20 in Ethereum (ERC20) for exactly the amount stated in the order.
- Once the network confirms your transfer, USD Coin Optimism leaves for your address. The order page tracks every step.
Check this before sending USDC ERC20
- 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 USDC 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.
Ethereum against OP Mainnet (Optimism)
| Ethereum | OP Mainnet (Optimism) | |
|---|---|---|
| Network type | Layer one (L1) | L2, optimistic rollup |
| Fees are paid in | ETH | ETH |
| Fee level | ≈ $0.0081 | ≈ $0.00016 |
| Speed | medium | fast |
| Block | ~12 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 | USDC in OP Mainnet (Optimism) | Depends: in some networks it is the bridged version of the token |
| 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 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: USDC ERC20 → USDC Optimism
What rate does USDC ERC20 to USDC Optimism run at?
As of Sep 17, 2026 01:38 it is 1 USDC ERC20 = 1.0001 USDC Optimism. The figure recalculates on its own, and the calculator always shows the fresh one. In dollars that is around $0.999824.
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 ERC20, and that one goes to the blockchain, not to us.
How long does USDC ERC20 to USDC Optimism 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.
Which network will USDC Optimism arrive in?
The payout leaves in Optimism. 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.
Will native USDC arrive, or a wrapper?
USDC Optimism is the standard USDC token in OP Mainnet (Optimism) — exactly what exchanges send when they withdraw into this network.
Do I need ETH to receive USDC Optimism?
Not to receive. ETH comes into play later, when you want to send USDC from your address.
What is wrong with the official OP Mainnet (Optimism) bridge?
An official deposit from Ethereum into OP Mainnet (Optimism) means connecting a wallet and signing a contract transaction. Here you simply send USDC ERC20 to the address from the order.
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, USDC Optimism to USDC ERC20?
Yes, the reverse direction is open: 1 USDC Optimism = 1.0001 USDC ERC20. The link sits right under the calculator.
