| RubyCash | Classic bridge | |
|---|---|---|
| What lands at your address | USDC in OP Mainnet (Optimism) | 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 |

| Timing | After confirmations in Avalanche C-Chain; 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 |
