How the USDC ERC20 → USDT Arbitrum order runs
- Work out the amount in the calculator: orders start at 100 USDC ERC20.
- Enter a USDT address in Arbitrum One 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, Tether leaves for your address. The order page tracks every step.
Check this before sending USDC ERC20
- The address network is Arbitrum One. Sending through another network usually means losing the transfer.
- The transfer must not be smaller than 100 USDC ERC20.
- 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 Arbitrum One.
- To move USDT 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.

How this differs from a classic bridge
| RubyCash | Classic bridge | |
|---|---|---|
| What lands at your address | USDT in Arbitrum One | 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 Arbitrum One | 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 |
