How the USDT Optimism → USDC AVAX C order runs
- Work out the amount in the calculator and press the exchange button.
- Enter a USDC address in Avalanche C-Chain and a way to reach you.
- Send USDT Optimism in Optimism for exactly the amount stated in the order.
- Once the network confirms your transfer, USD Coin leaves for your address. The order page tracks every step.
Check this before sending USDT Optimism
- The address network is Avalanche C-Chain. 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 Avalanche C-Chain.
- To move USDC on later, put a little AVAX 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 | USDC in Avalanche C-Chain | 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 Avalanche C-Chain | 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 |
